SUMMARY

    In this prospectus, the words "Company," "Harrah's," "we," "our," "ours," and "us" refer to Harrah's Entertainment, Inc., a Delaware corporation ("Harrah's Entertainment"), and its wholly-owned subsidiary, Harrah's Operating Company, Inc., a Delaware corporation ("Harrah's Operating"), unless otherwise stated or the context otherwise requires. The following summary contains basic information about this offering. It may not contain all the information that is important to you. The "Description of Notes" section of this prospectus contains more detailed information regarding the terms and conditions of the notes.


THE COMPANY

    We operate in more markets than any other casino company and offer a Harrah's casino experience within a three-hour drive of one-third of the U.S. population. On July 31, 2001, we consummated our acquisition of Harveys Casino Resorts. The addition of the Harveys properties expanded our geographic distribution to 25 casinos in 12 states, increased our nationwide casino square footage by almost 15% and added 1,109 hotel rooms, 149 table games, excluding poker tables, and 5,768 slot machines to serve our customers. Our casino entertainment facilities, operating under the Harrah's, Rio, Showboat, Harveys and Players brand names, include eleven land-based casinos, ten riverboat or dockside casinos, and three casinos on Indian reservations. We also own a non-controlling interest in and manage the only land-based casino in New Orleans, Louisiana. In addition, during the first quarter of 2000, we signed a definitive agreement with the Rincon San Luiseno Band of Mission Indians to build and manage a $125 million casino and hotel on Rincon tribal land. The tribe began operations of a temporary casino on January 11, 2001. We do not manage the tribe's temporary casino.

Brand Strategy

    We seek to differentiate ourselves by building the industry's only national brand. To accomplish this objective, we have invested significant time and resources learning who the best customers in our industry are and what they want from a gaming experience. We are building our brand with a focus on the broad middle market gaming segment, but because of our strategy, we are uniquely positioned to appeal to those customers that play in more than one market. We believe that these customers represent 12% of the industry's customers, but generate 55% of the industry's revenue. Our strategy is comprised of four integrated components which we believe combine to create a sustainable competitive advantage for Harrah's. These four elements are national geographic distribution, quality facilities, proprietary technology and superior customer service.

National Geographic Distribution

Quality Facilities

6


Proprietary Technology

Superior Customer Service

    We believe that our strategy continues to evolve and build loyalty with our target customer through the use and development of our unique capabilities in addition to the four integrated components described above. We have developed unique capabilities such as Total Rewards, sophisticated direct marketing and telemarketing tools and programs, enhanced revenue management systems, Internet capabilities and data mining and data modeling capabilities. These capabilities, together with our information rich and extensive customer database, allow us to build loyalty that translates into same store sales growth.

    Our principal executive offices are located at One Harrah's Court, Las Vegas, Nevada 89119. Our telephone number is (702) 407-6000.

THE EXCHANGE OFFER

The Exchange Offer   We are offering to exchange our exchange notes for our outstanding private notes properly tendered and accepted. You may tender outstanding notes only in denominations of $1,000 and multiples of $1,000. We will issue the exchange notes on or promptly after the date that the exchange offer expires. As of the date of this prospectus, $500,000,000 in aggregate principal amount of private notes are outstanding.

Expiration Date

 

The exchange offer will expire at 5:00 p.m., New York City time, on October 9, 2001, unless extended, in which case the expiration date will mean the latest date and time to which we extend the exchange offer.

Conditions to the Exchange Offer

 

The exchange offer is not subject to any conditions other than that it not violate applicable law or any applicable interpretation of the staff of the SEC. The exchange offer is not conditioned upon any minimum principal amount of private notes being tendered for exchange.

Procedures for Tendering Private Notes

 

If you wish to tender your private notes for exchange notes pursuant to the exchange offer you must transmit to the U.S. Bank, N.A. (formerly known as Firstar Bank, N.A.), as exchange agent, on or before the expiration date, either:

 

 


 

a computer generated message transmitted through The Depository Trust Company's Automated Tender Offer Program system and received by the exchange agent and forming a part of a confirmation of book-entry transfer in which you acknowledge and agree to be bound by the terms of the letter of transmittal; or

 

 


 

a properly completed and duly executed letter of transmittal, which accompanies this prospectus, or a facsimile of the letter of transmittal, together with your private notes and any other required documentation, to the exchange agent at its address listed in this prospectus and on the front cover of the letter of transmittal.

8



 

 

If you cannot satisfy either of these procedures on a timely basis, then you should comply with the guaranteed delivery procedures described below. By executing the letter of transmittal, you will make the representations to us described under "The Exchange Offer—Procedures for Tendering."

Special Procedures for Beneficial Owners

 

If you are a beneficial owner whose private notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your private notes in the exchange offer, you should contact the registered holder promptly and instruct the registered holder to tender on your behalf. If you wish to tender on your own behalf, you must either (1) make appropriate arrangements to register ownership of the private notes in your name or (2) obtain a properly completed bond power from the registered holder, before completing and executing the letter of transmittal and delivering your private notes.

Guaranteed Delivery Procedures

 

If you wish to tender your private notes and time will not permit the documents required by the letter of transmittal to reach the exchange agent before the expiration date, or the procedure for book-entry transfer cannot be completed on a timely basis, you must tender your private notes according to the guaranteed delivery procedures described in this prospectus under the heading "The Exchange Offer—Guaranteed Delivery Procedures."

Acceptance of Private Notes and Delivery of Exchange Notes

 

Subject to the satisfaction or waiver of the conditions to the exchange offer, we will accept for exchange any and all private notes which are validly tendered in the exchange offer and not withdrawn before 5:00 p.m., New York City time, on the expiration date.

Withdrawal Rights

 

You may withdraw the tender of your private notes at any time before 5:00 p.m., New York City time, on the expiration date, by complying with the procedures for withdrawal described in this prospectus under the heading "The Exchange Offer—Withdrawal of Tenders."

9



Liquidated Damages

 

We issued the private notes on June 14, 2001, to the initial purchasers pursuant to a purchase agreement. At the same time, we entered into a registration rights agreement with the initial purchasers requiring us to make the exchange offer. The registration rights agreement also required us to:

 

 


 

cause the registration statement filed with respect to the exchange offer to be declared effective by December 11, 2001; and

 

 


 

consummate the exchange offer by January 10, 2002.

Exchange Agent

 

U.S. Bank, N.A. (formerly known as Firstar Bank, N.A.), the trustee under the indenture governing the private notes, is serving as the exchange agent.

Consequences of Failure to Exchange Notes

 

If you do not exchange your private notes for exchange notes, you will continue to be subject to the restrictions on transfer provided in the private notes and in the indenture governing the private notes. In general, the private notes may not be offered or sold, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not currently plan to register the private notes under the Securities Act.

Registration Rights Agreement

 

You are entitled to exchange your private notes for exchange notes with substantially identical terms. The exchange offer satisfies this right. After the exchange offer is completed, you will no longer be entitled to any exchange or registration rights with respect to your private notes. Under the circumstances described in the registration rights agreement, you may require us to file a shelf registration statement under the Securities Act.

We explain the exchange offer in greater detail beginning on page 20.

10



THE EXCHANGE NOTES

    The form and terms of the exchange notes are the same as the form and terms of the private notes, except that the exchange notes will be registered under the Securities Act and, therefore, the exchange notes will not be subject to the transfer restrictions, registration rights and provisions providing for an increase in the interest rate applicable to the private notes. The exchange notes will evidence the same debt as the private notes and both the private notes and the exchange notes, collectively, the "notes," are governed by the same indenture.

Total Amount of Notes Offered   $500,000,000 principal amount of 7.125% Senior Notes due 2007.

Maturity

 

June 1, 2007.

Interest

 

7.125% per year.

Interest Payment Dates

 

June 1 and December 1, beginning on December 1, 2001. Interest will accrue from the issue date of the notes.

Optional Redemption

 

We may redeem some or all of the exchange notes at any time at the redemption price described in the "Description of Notes" section under the heading "Optional Redemption," plus accrued interest to the date of redemption.

Guarantee

 

Harrah's Entertainment unconditionally guarantees the notes. However, because Harrah's Entertainment's sole material asset is its equity interest in Harrah's Operating, Harrah's Entertainment is dependent on the receipt of dividends or other payments from Harrah's Operating to make payments on the guarantee of the notes.

Ranking

 

The notes are unsecured senior obligations of Harrah's Operating. At June 30, 2001, after giving effect to the issuance of the notes, the notes would have ranked equal in right of payment with $1,804.9 million of other senior indebtedness of Harrah's Operating, including $645.0 million under our credit facility. However, $100.5 million of such indebtedness represents obligations of our subsidiaries, all of which would effectively rank senior to the notes.

Covenants

 

The indenture governing the notes contains covenants that limit our ability and our subsidiaries' ability to:

 

 


 

enter into certain sale and lease-back transactions;

 

 


 

incur liens on our assets to secure debt;

 

 


 

merge or consolidate with another company; and

 

 


 

transfer or sell substantially all of our assets.

11



 

 

For more details, see the "Additional Covenants of Harrah's Operating" section under the headings "Description of Notes" and "Merger, Consolidation or Sale of Assets" in this prospectus.

Form of Exchange Notes

 

The exchange notes will be represented by one or more permanent global certificates, in fully registered form, deposited with a custodian for, and registered in the name of a nominee of, The Depository Trust Company, as depositary. You will not receive exchange notes in certificated form unless one of the events described under the heading "Book-Entry; Delivery; Form and Transfer—Transfers of Interests in Global Notes for Certificated Notes" occurs. Instead, beneficial interests in the exchange notes will be shown on, and transfers of these notes will be effected only through, records maintained in book-entry form by The Depository Trust Company and its participants.

Use of Proceeds

 

We will not receive any cash proceeds in the exchange offer.

We explain the exchange notes in greater detail beginning on page 31.

12



RISK FACTORS

    You should read carefully this entire prospectus before investing in the notes. Among the factors that may adversely affect an investment in the notes are the following:

Our substantial indebtedness could adversely affect our financial results and prevent us from fulfilling our obligations under the notes.

    We currently have a significant amount of indebtedness. At June 30, 2001, our total consolidated indebtedness was approximately $3,052.9 million. See "Capitalization." On July 31, 2001, we incurred an additional $631.4 million in indebtedness to fund the acquisition of Harveys Casino Resorts.

    The notes will not restrict our ability to borrow substantial additional unsecured indebtedness in the future. If new indebtedness is added to our current debt levels, the related risks that we now face could increase.

    Our indebtedness could have important consequences for the holders of the notes, including:

Servicing our indebtedness will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.

    Our ability to make payments on our indebtedness, including these notes, and to fund planned capital expenditures will depend on our ability to generate cash in the future. Harrah's Entertainment is a holding company and Harrah's Operating conducts substantially all of its operations through its subsidiaries. As a result, our ability to meet our debt service obligations substantially depends upon our subsidiaries' cash flow and payments of funds to us by our subsidiaries. This ability, to some extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

    Based on our current level of operations and recent acquisitions, we believe our cash flow from operations, available cash and available borrowings under our credit facility will be adequate to meet our liquidity needs for the next few years.

    We cannot assure you, however, that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our credit facility in an amount sufficient to enable us to pay our indebtedness, including these notes, or to fund our other liquidity needs. We may need to refinance all or a portion of our indebtedness, including these notes on or before maturity. We cannot assure you that we will be able to refinance any of our indebtedness on commercially reasonable terms or at all.

Although these notes are referred to as "senior notes," they will be effectively subordinated to our secured indebtedness and the indebtedness of our subsidiaries.

    The notes are unsecured and therefore will be effectively subordinated to any secured indebtedness we may incur to the extent of the value of the assets securing such indebtedness. In the event of a

13


bankruptcy or similar proceeding involving us, our assets which serve as collateral will be available to satisfy the obligations under any secured indebtedness before any payments are made on the notes. In addition, our subsidiaries will not guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, creditors of our subsidiaries will generally be entitled to payment of their claims from the assets of those subsidiaries before any assets are made available for distribution to us, except to the extent we may also have a claim as a creditor. At June 30, 2001, these notes were effectively junior to approximately $100.5 million of indebtedness of subsidiaries of Harrah's Operating. The notes are also effectively junior to the $631.4 million of additional indebtedness we incurred on July 31, 2001, to fund our acquisition of Harveys Casino Resorts.

We may incur additional losses related to the New Orleans land-based casino.

    On January 4, 2001, JCC Holding Company, the owner and operator of the New Orleans, Louisiana, land-based casino managed by one of our subsidiaries pursuant to a contract, filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code. On January 12, 2001, JCC Holding filed a plan of reorganization which was supported by us, the bank lenders and bondholders of JCC Holding. The plan of reorganization was consummated on March 29, 2001.

    We could face additional losses relating to the New Orleans casino. In connection with the consummation of the plan, we guaranteed payments to the State of Louisiana of up to $230 million. We also received $51 million in term debt of the reorganized company and we are providing $35 million in revolving debt to the reorganized company. If the casino does not perform well and experiences financial difficulty, we would be responsible for state payments to the extent that JCC Holding is unable to pay such amounts. We could also incur losses resulting from the loans we provided to and our equity ownership in JCC Holding. In addition, we face exposure to accounting losses if the casino does not perform well. It is also possible that other stakeholders in the casino could pursue litigation against us.

We may require you to dispose of your notes or redeem your notes if any gaming authority finds you unsuitable to hold them.

    We may require you to dispose of your notes or redeem your notes if any gaming authority finds you unsuitable to hold them or in order to otherwise comply with gaming laws to which we are subject, as more fully described in the sections entitled "Regulation and Licensing" and "Description of the Exchange Notes—Mandatory Disposition Pursuant to Gaming Laws."

An active trading market may not develop for the notes.

    There is no existing trading market for the notes. Although the initial purchasers of the private notes have informed us that they currently intend to make a market in the notes, they have no obligation to do so and may discontinue making a market at any time without notice.

    We do not intend to apply for listing of the exchange notes, on any securities exchange or for quotation on the Nasdaq National Market.

    The liquidity of any market for the notes will depend on a number of factors, including:

    We cannot assure you that an active market for the notes will develop or, if developed, that it will continue.

14



USE OF PROCEEDS

    The exchange offer satisfies an obligation under the registration rights agreement. We will not receive any cash proceeds from the exchange offer.


RECENT DEVELOPMENTS

    On August 9, 2001, we notified the trustee and registered holders of $150 million aggregate principal amount of 105/8% Senior Subordinated Notes due 2006 that we intend to redeem these notes on September 11, 2001. We assumed the liability for these notes when we acquired Harveys Casino Resorts on July 31, 2001, and will fund the redemption using funds drawn under our existing revolving credit facilities.

Property EBITDA consists of operating profit before depreciation and amortization, write-downs, reserves and recoveries and project opening costs. See Exhibit 12 to our 2000 Form 10-K for the computations of Property EBITDA. Property EBITDA is a supplemental financial measure used by management, as well as industry analysts, to evaluate our operations. However, Property EBITDA should not be construed as an alternative to Income from operations (as an indicator of our operating performance) or to Cash Flows from operating activities (as a measure of liquidity) as determined in accordance with generally accepted accounting principles and presented in our Consolidated Financial Statements. All companies do not calculate EBITDA in the same manner. As a result, Property EBITDA as presented by our Company may not be comparable to similarly titled measures presented by other companies.

REGULATION AND LICENSING

    The ownership and operation of casino gaming facilities are subject to extensive governmental regulation. Each of the jurisdictions in which we operate gaming facilities requires us to hold various licenses, findings of suitability, registrations, permits, and approvals (collectively, "Gaming Licenses"). Under the gaming laws of Nevada, New Jersey, Mississippi, Missouri, Louisiana, Illinois, Indiana, Iowa, Colorado, Arizona, California, Kansas and North Carolina, and our corporate charter, holders of our securities may be required, under certain circumstances, to dispose of the securities. If the holder refuses to do so, we may be required to repurchase the security. In addition, the management contracts and the operation of gaming and casinos on Indian land in the United States are subject to the Indian Gaming Regulatory Act, which is administered by the National Indian Gaming Commission.

    Consequently, each holder of notes, by accepting any notes, will be deemed to have agreed to be bound by the requirements imposed by the gaming authority in any jurisdiction we, or any of our subsidiaries, conduct or propose to conduct gaming activities. See "Description of Notes—Mandatory Disposition Pursuant to Gaming Laws." In addition, under the indenture governing the notes, each holder and beneficial owner of notes, by accepting or otherwise acquiring an interest in any notes, will be deemed to have agreed to apply for a license, qualification, or finding of suitability as required by the gaming authorities in any jurisdiction in which we, or any of our subsidiaries, conduct or propose to conduct gaming activities. If a holder of notes fails to apply or become licensed or qualified or is found unsuitable, we shall have the right, at our option:

    We will not be responsible for any costs or expenses incurred by any such holder or beneficial owner in connection with its application for a license, qualification or finding of suitability. Harrah's Operating's charter also expressly provides that debt securities issued by Harrah's Operating may be redeemed if a holder of such securities is found unsuitable by any governmental agency.

    The Nevada Gaming Commission, the New Jersey Casino Control Commission, the Mississippi Gaming Commission, the Missouri Gaming Commission, the Louisiana Gaming Control Board, the Illinois Gaming Board, the Indiana Gaming Commission, the Iowa Racing and Gaming Commission and the Colorado Limited Gaming Control Commission may also, among other things, limit, condition, suspend or revoke a Gaming License or approval to own the stock or joint venture interests of any of our operations in such licensing authority's jurisdiction, for any cause deemed reasonable by such licensing authority. Substantial fines or forfeiture of assets for violations of gaming laws or regulations may be levied against us, such subsidiaries and joint ventures and the persons involved. The suspension or revocation of any of our Gaming Licenses or the levy on us of substantial fines or forfeiture of assets could have a material adverse effect on our business.

    Under Nevada and Mississippi law, we may not make a public offering of our securities without the prior approval of the applicable gaming commission if we intend to use the offering proceeds to construct, acquire or finance a gaming facility, or retire or extend existing obligations incurred for such purposes. On November 20, 2000, the Nevada Gaming Commission granted Harrah's Entertainment and Harrah's Operating prior approval to make offerings for a period of two years, subject to certain conditions. The Chairman of the Nevada State Gaming Control Board may rescind its approval for good cause without prior notice upon the issuance of an interlocutory stop order. These prior approvals

18


do not constitute a finding, recommendation or approval by the Nevada Gaming Commission or the Nevada State Gaming Control Board as to the accuracy or adequacy of this prospectus, or the investment merits of the notes. Any representation to the contrary is unlawful. The Company received a similar two-year approval from the Mississippi Gaming Commission on August 16, 2001. Additionally, Indiana requires approval of any debt transaction involving more than $1,000,000. The Executive Director of the Indiana Gaming Commission issued a waiver to us to sell the private notes without Commission approval, and on August 23, 2001, the Commission approved the issuance of these registered notes. Under Indiana law, a riverboat owner licensee or any other person may not lease, hypothecate, borrow money against or loan money against an owner's riverboat gaming license.

    To date, we have obtained all Gaming Licenses necessary for the operation of our gaming activities. Gaming Licenses and related approvals, however, are deemed to be privileges under the laws of the jurisdictions in which we conduct gaming activities, and no assurances can be given that any new Gaming Licenses that may be required in the future will be granted or that existing Gaming Licenses will not be revoked or suspended.

    The foregoing is only a summary of the applicable regulatory requirements. For a more detailed description of the applicable regulatory requirements, including requirements under gaming laws and our corporate charter, see "Governmental Regulation" in Harrah's Entertainment's Annual Report on Form 10-K for the year ended December 31, 2000, incorporated by reference herein.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

    We sold the private notes on June 14, 2001, to Salomon Smith Barney Inc., Commerzbank Capital Markets Corp., Banc of America Securities LLC, Fleet Securities, Inc., Wells Fargo Brokerage Services, LLC, Credit Suisse First Boston Corporation, Deutsche Banc Alex. Brown Inc., SG Cowen Securities Corporation, CIBC World Markets Corp., Credit Lyonnais Securities (USA) Inc., Scotia Capital (USA) Inc., Bear, Stearns & Co. Inc., Goldman, Sachs & Co., Jefferies & Co., Inc., and Merrill Lynch, Pierce, Fenner & Smith Incorporated, the initial purchasers, pursuant to a purchase agreement. The initial purchasers subsequently sold the private notes to "qualified institutional buyers," as defined in Rule 144A under the Securities Act, in reliance on Rule 144A and to certain persons outside the United States in reliance on Regulation S of the Securities Act. As a condition to the sale of the private notes, we entered into a registration rights agreement with the initial purchasers on June 14, 2001. Pursuant to the registration rights agreement, we agreed that, unless the exchange offer is not permitted by applicable law or SEC policy, we would:

    Upon the effectiveness of this registration statement, we will offer the exchange notes in exchange for the private notes. We filed a copy of the registration rights agreement as an exhibit to the registration statement.

Resale of the Exchange Notes

    We are making the exchange offer in reliance on the position of the staff of the SEC as set forth in interpretive letters addressed to third parties in other transactions. For further information on the SEC's position, see Exxon Capital Holdings Corporation, available May 13, 1988, Morgan Stanley & Co. Incorporated, available June 5, 1991 and Shearman & Sterling, available July 2, 1993, and other interpretive letters to similar effect. We have not sought our own interpretive letter, however, and we cannot assure you that the staff would make a similar determination with respect to the exchange offer as it has in interpretive letters to third parties. Based on these interpretations by the staff, we believe that the exchange notes issued under the exchange offer may be offered for resale, resold or otherwise transferred by you, without further compliance with the registration and prospectus delivery provisions of the Securities Act, so long as you:

20


    By tendering the private notes in exchange for exchange notes, you will be required to represent to us that each of the above statements applies to you. If you are participating in or intend to participate in, a distribution of the exchange notes, or have any arrangement or understanding with any person to participate in a distribution of the exchange notes to be acquired in this exchange offer, you may be deemed to have received restricted securities and may not rely on the applicable interpretations of the staff of the SEC. If you are so deemed, you will have to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction.

    Each broker-dealer that receives exchange notes for its own account in exchange for private notes, which the broker-dealer acquired as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. The letter of transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act. A broker-dealer may use this prospectus, as it may be amended or supplemented from time to time, in connection with resales of exchange notes received in exchange for private notes which the broker-dealer acquired as a result of market-making or other trading activities.

Terms of the Exchange Offer

    Upon the terms and subject to the conditions described in this prospectus and in the letter of transmittal, we will accept any and all private notes validly tendered and not withdrawn before the expiration date. We will issue $1,000 principal amount of exchange notes in exchange for each $1,000 principal amount of outstanding private notes surrendered pursuant to the exchange offer. You may tender private notes only in integral multiples of $1,000.

    The form and terms of the exchange notes are the same as the form and terms of the private notes except that:

    The exchange notes will evidence the same debt as the private notes and will be issued under the same indenture, so the exchange notes and the private notes will be treated as a single class of debt securities under the indenture.

    As of the date of this prospectus, $500,000,000 in aggregate principal amount of the private notes are outstanding and registered in the name of Cede & Co., as nominee for The Depository Trust Company, or DTC. Only a registered holder of the private notes, or such holder's legal representative or attorney-in-fact, as reflected on the records of the trustee under the indenture, may participate in the exchange offer. We will not set a fixed record date for determining registered holders of the private notes entitled to participate in the exchange offer.

    You do not have any appraisal or dissenters' rights under the indenture in connection with the exchange offer. We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement and the applicable requirements of the Securities Act, the Exchange Act and the rules and regulations of the SEC.

21


    We will be deemed to have accepted validly tendered private notes when, as and if we had given oral or written notice of acceptance to the exchange agent. The exchange agent will act as your agent for the purposes of receiving the exchange notes from us.

    If you tender private notes in the exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of private notes pursuant to the exchange offer. We will pay all charges and expenses, other than the applicable taxes described below, in connection with the exchange offer.

Expiration Date; Extensions; Amendments

    The term "expiration date" will mean 5:00 p.m., New York City time on October 9, 2001, unless we, in our sole discretion, extend the exchange offer, in which case the term "expiration date" will mean the latest date and time to which we extend the exchange offer.

    To extend the exchange offer, we will:

each before 9:00 a.m., New York City time, on the next business day after the previously scheduled expiration date.

    We reserve the right, in our reasonable discretion:

    We will follow any delay in acceptance, extension or termination as promptly as practicable by oral or written notice to the exchange agent and a press release or oral or written notice to the holders of the private notes. If we amend the exchange offer in a manner we determine constitutes a material change, we will promptly disclose the amendment in a prospectus supplement that we will distribute to the registered holders. We will also extend the exchange offer for a period of five to ten business days, depending upon the significance of the amendment and the manner of disclosure, if the exchange offer would otherwise expire during the five to ten business day period.

Interest on the Exchange Notes

    The exchange notes will bear interest at the same rate and on the same terms as the private notes. Consequently, the exchange notes will bear interest at a rate equal to 7.125% per annum. Interest will be payable semi-annually in arrears on June 1 and December 1, commencing December 1, 2001.

    Interest on the exchange notes will accrue from the last interest payment date on which interest was paid on the private notes or, if no interest was paid on the private notes, from the date of issuance of the private notes, which was June 14, 2001. We will deem the right to receive any interest accrued on the private notes waived by you if we accept your private notes for exchange.

22


Procedures for Tendering

    You may tender private notes in the exchange offer only if you are a registered holder of private notes. To tender in the exchange offer, you must:

    In addition, either:

    The term "agent's message" means a message, transmitted by DTC to, and received by, the exchange agent and forming a part of a book-entry confirmation, which states that DTC has received an express acknowledgment from its participant tendering private notes which are the subject of this book-entry confirmation that this participant has received and agrees to be bound by the terms of the letter of transmittal, and that we may enforce the terms of the letter of transmittal against the participant.

    Your tender, if not withdrawn before the expiration date, will constitute an agreement between you and us in accordance with the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

    The method of delivery of private notes and the letter of transmittal and all other required documents to the exchange agent is at your election and risk. We recommend that instead of delivery by mail, you use an overnight or hand delivery service, properly insured. If you choose delivery by mail, we recommend registered mail, return receipt requested, properly insured. In all cases, you should allow sufficient time to assure delivery to the exchange agent before the expiration date. You should not send letters of transmittal or private notes to us. You may request your respective brokers, dealers, commercial banks, trust companies or nominees to effect the transactions described above for you.

    If you are a beneficial owner of private notes whose private notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender your private notes, you should contact the registered holder promptly and instruct the registered holder to tender on your behalf. If you wish to tender on your own behalf, before completing and executing the letter of transmittal and delivering the private notes, you must either:

23


    The transfer of registered ownership may take considerable time. Unless the private notes are tendered:

an eligible guarantor institution must guarantee the signatures on a letter of transmittal or a notice of withdrawal described below under "—Withdrawal of Tenders."

    If the letter of transmittal is signed by the registered holder(s) of the private notes tendered, the signature must correspond exactly with the name(s) written on the face of the private notes. If the letter of transmittal is signed by a participant in DTC, the signature must correspond exactly with the name as it appears on the security position listing as the holder of the private notes.

    If the letter of transmittal is signed by a person other than the registered holder of any of the private notes listed, the private notes must be endorsed or accompanied by a properly completed bond power that authorizes that person to tender the private notes on behalf of the registered holder, signed by the registered holder exactly as the registered holder's name appears on the private notes.

    If the letter of transmittal or any private notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, they should so indicate when signing, and unless waived by us, they must submit evidence satisfactory to us of their authority to so act with the letter of transmittal.

    A tender will be deemed to have been received as of the date when the tendering holder's duly signed letter of transmittal accompanied by the private notes tendered, or a timely confirmation received by a book-entry transfer of private notes into the exchange agent's account at DTC with an agent's message, or a notice of guaranteed delivery from an eligible institution is received by the exchange agent. Issuances of exchange notes in exchange for private notes tendered under a notice of guaranteed delivery by an eligible institution will be made only against delivery of the letter of transmittal, and any other required documents, and the tendered private notes, or a timely confirmation received of a book-entry transfer of private notes into the exchange agent's account at DTC with an agent's message, to the exchange agent.

    The exchange agent and the depositary have confirmed that any financial institution that is a participant in DTC's system may utilize the depositary's Automated Tender Offer Program to tender notes.

    We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance and withdrawal of tendered private notes, which determination will be final and binding. We reserve the absolute right to reject any and all private notes not properly tendered or any private notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to particular private notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions

24


in the letter of transmittal, will be final and binding on all parties. Unless waived, you must cure any defects or irregularities in connection with tenders of private notes within the time we determine. Although we intend to notify you of defects or irregularities with respect to tenders of private notes, neither we, the exchange agent nor any other person will incur any liability for failure to give you that notification. We will not deem tenders of private notes to have been made until you cure, or we waive, any defects or irregularities.

    While we have no present plan to acquire any private notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any private notes that are not tendered in the exchange offer, we reserve the right in our sole discretion to purchase or make offers for any private notes that remain outstanding after the expiration date. We also reserve the right to terminate the exchange offer, as described below under "—Conditions," and, to the extent permitted by applicable law, purchase private notes in the open market, in privately negotiated transactions or otherwise. The terms of any of those purchases or offers could differ from the terms of the exchange offer.

    By tendering, you will be making several representations to us including that:

    If you are a broker-dealer that will receive exchange notes for your own account in exchange for private notes that were acquired as a result of market-making activities or other trading activities, you will also be required to acknowledge in the letter of transmittal that you will deliver a prospectus in connection with any resale of those exchange notes; however, by so acknowledging and by delivering a prospectus, you will not be deemed to admit that you are an underwriter within the meaning of the Securities Act.

Return of Private Notes

    If we do not accept any tendered private notes for any reason described in the terms and conditions of the exchange offer or if you withdraw or submit private notes for a greater principal amount than you desire to exchange, we will return the unaccepted, withdrawn or non-exchanged notes without expense to you as promptly as practicable. In the case of private notes tendered by book-entry

25


transfer into the exchange agent's account at the depositary pursuant to the book-entry transfer procedures described below, we will credit the private notes to an account maintained with the DTC as promptly as practicable.

Book-Entry Transfer

    The exchange agent will make a request to establish an account with respect to the private notes at DTC for purposes of the exchange offer within two business days after the date of this prospectus. Any financial institution that is a participant in DTC's systems may make book-entry delivery of private notes by causing DTC to transfer the private notes into the exchange agent's account at DTC in accordance with the DTC's procedures for transfer. However, although delivery of private notes may be effected through book-entry transfer at DTC, an agent's message or the letter of transmittal or a facsimile of the letter of transmittal, with any required signature guarantees and any other required documents, must be transmitted to the exchange agent at the address below under "—Exchange Agent" on or before the expiration date or pursuant to the guaranteed delivery procedures described below. Delivery of documents to DTC does not constitute delivery to the exchange agent.

Guaranteed Delivery Procedures

    If you are a registered holder and wish to tender your private notes and (1) the notes are not immediately available, (2) you cannot deliver the private notes, the letter of transmittal or any other required documents to the exchange agent before the expiration date, or (3) the procedures for book-entry transfer cannot be completed on a timely basis and an agent's message delivered, you may effect a tender if:

    Upon request, the exchange agent will send to you a notice of guaranteed delivery if you wish to tender your notes according to the guaranteed delivery procedures described above.

Withdrawal of Tenders

    Except as otherwise provided in this prospectus, you may withdraw tenders of private notes at any time before 5:00 p.m., New York time, on the expiration date.

26


    To withdraw a tender of private notes in the exchange offer, the exchange agent must receive a written or facsimile transmission notice of withdrawal at its address listed in this prospectus before the expiration date. Any notice of withdrawal must:

    We will determine in our sole discretion all questions as to the validity, form and eligibility of the notices, and our determination will be final and binding on all parties. We will not deem any properly withdrawn private notes to have been validly tendered for purposes of the exchange offer, and we will not issue exchange notes with respect to those private notes, unless you validly retender the withdrawn private notes. You may retender properly withdrawn private notes by following one of the procedures described above under "—Procedures for Tendering" at any time before the expiration date.

Conditions

    Notwithstanding any other term of the exchange offer, we will not be required to accept for exchange, or exchange the exchange notes for, any private notes, and may terminate or amend the exchange offer as provided in this prospectus before the acceptance of the private notes, if, in our reasonable judgment, the exchange offer violates applicable law, rules or regulations or an applicable interpretation of the staff of the SEC or any action or proceeding has been instituted or threatened in any court or before any governmental agency with respect to the exchange offer which, in our judgment, might impair our ability to proceed with the exchange offer or materially and adversely affect us.

    If we determine in our reasonable discretion that any of these conditions are not satisfied, we may:

    If the waiver constitutes a material change to the exchange offer, we will promptly disclose the waiver by means of a prospectus supplement that we will distribute to the registered holders of the private notes, and we will extend the exchange offer for a period of five to ten business days, depending upon the significance of the waiver and the manner of disclosure to the registered holders, if the exchange offer would otherwise expire during the five to ten business day period.

Termination of Rights

    All of your rights under the registration rights agreement will terminate upon consummation of the exchange offer except with respect to our continuing obligations:

27


Shelf Registration

    If:

we will, at our cost:

    We will provide to each relevant holder copies of the prospectus which is part of the shelf registration statement, notify each holder when the shelf registration statement has been filed and when it has become effective and take certain other actions as are required to permit unrestricted resales of the notes. A holder that sells notes pursuant to the shelf registration statement generally:

28


In addition, a holder of private notes will be required to deliver information to be used in connection with the shelf registration statement in order to have the holder's private notes included in the shelf registration statement and to benefit from the provisions regarding liquidated damages described below.

Liquidated Damages

    If:

the interest rate borne by the private notes will increase by 0.25% per year upon the occurrence of any of the events described above, each of which will constitute a registration default. The interest rate will increase by 0.25% per annum at the end of each subsequent 90-day period until all such registration defaults have been cured, but in no event shall such rate exceed 0.50% per annum. Following the cure of all registration defaults, the accrual of the additional interest will cease and the interest rate will revert to the original rate.

Exchange Agent

    We have appointed U.S. Bank, N.A. (formerly known as Firstar Bank, N.A.), as exchange agent for the exchange offer. You should direct questions and requests for assistance, requests for additional copies of this prospectus or the letter of transmittal and requests for a notice of guaranteed delivery to the exchange agent addressed as follows.

By registered or Certified Mail, Overnight Delivery, or Hand Delivery:

U.S. Bank, N.A.
101 East Fifth Street
St. Paul, MN 55101
Attention: Frank P. Leslie
Corporate Trust

By Facsimile:
(651) 229-6415

    Delivery to an address other than the one stated above or transmission via a facsimile number other than the one stated above will not constitute a valid delivery.

29


Fees and Expenses

    We will bear the expenses of soliciting tenders. We are making the principal solicitation by mail; however, our and our affiliates' officers and regular employees may make additional solicitations by telegraph, telephone or in person.

    We have not retained any dealer manager in connection with the exchange offer and will not make any payments to brokers, dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses.

    We will pay the cash expenses incurred in connection with the exchange offer which we estimate to be approximately $375,000. These expenses include registration fees, fees and expenses of the exchange agent and the trustee, accounting and legal fees and printing costs, among others.

    We will pay all transfer taxes, if any, applicable to the exchange of notes pursuant to the exchange offer. If, however, a transfer tax is imposed for any reason other than the exchange of the private notes pursuant to the exchange offer, then you must pay the amount of these transfer taxes. If you do not submit satisfactory evidence of payment of these taxes or exemption from payment with the letter of transmittal, we will bill the amount of these transfer taxes directly to you.

Consequence of Failures to Exchange

    Participation in the exchange offer is voluntary. We urge you to consult your financial and tax advisors in making your decisions on what action to take.

    Private notes that are not exchanged for exchange notes pursuant to the exchange offer will remain restricted securities. Accordingly, those private notes may be resold only:

    In each case, the private notes may be resold only in accordance with any applicable securities laws of any state of the United States or any other applicable jurisdiction.

DESCRIPTION OF NOTES

General

    The exchange notes will be issued pursuant to an indenture among Harrah's Operating, Harrah's Entertainment and U.S. Bank, N.A. (formerly known as Firstar Bank, N.A.), as trustee. The following summary highlights certain material terms of the exchange notes, which are identical in all material respects to the terms of the private notes, except that the registration rights and related liquidated damages provisions, and the transfer restrictions that apply to the private notes, do not apply to the exchange notes. We urge you to read the indenture because it, and not this description, defines your rights as holders of the exchange notes. As used in this section, the terms "note" and "notes" refer to the exchange notes.

    The notes:

    The guarantees by Harrah's Entertainment will be:

    We may from time to time without notice to, or the consent of, the holders of a series of senior securities, create and issue additional notes, equal in rank to the notes offered hereby in all respects (or in all respects except for the payment of interest accruing prior to the issue date of the new notes or except for the first payment of interest following the issue date of the new notes) so that the new notes may be consolidated and form a single series of notes with the notes offered hereby and have the same terms as to status, redemption or otherwise as the notes offered hereby. In the event that we issue additional senior notes, we will prepare a new offering memorandum or prospectus.

Principal, Maturity and Interest

    Harrah's will issue the notes in fully registered book-entry form only, without coupons in denominations of $1,000 and any integral multiple of $1,000. The notes will mature on June 1, 2007, referred to as the "Maturity Date." Each note will bear interest at the rate of 7.125% from June 14, 2001, or from the most recent interest payment date to which interest has been paid or provided for, payable semiannually on June 1 and December 1 of each year (each, an "Interest Payment Date"), commencing December 1, 2001, to the persons in whose names such notes are registered at the close of business on the date fifteen days prior to such Interest Payment Date.

    If any Interest Payment Date, date of redemption (the "Redemption Date") or Maturity Date of any of the notes is not a business day, then payment of principal, premium, if any, and interest will be made on the next succeeding business day. No interest will accrue on the amount so payable for the period from such Interest Payment Date, Redemption Date or Maturity Date, as the case may be, to the date payment is made. Interest on the notes will be computed on the basis of a 360-day year of twelve 30-day months.

    The notes will not be entitled to the benefit of any sinking fund.

31


Optional Redemption

    The notes are redeemable, in whole or in part, at any time, and at our option, at a redemption price equal to the greater of:

plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date.

    "Adjusted Treasury Rate" means, with respect to any Redemption Date:

    The Adjusted Treasury Rate shall be calculated on the third business day preceding the Redemption Date.

    "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such securities ("Remaining Life").

    "Comparable Treasury Price" means (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

    "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by us.

    "Reference Treasury Dealer" means:

32


    "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker at 5:00 p.m., New York City time, on the third business day preceding such Redemption Date.

    We will mail a notice of redemption at least 30 days but not more than 60 days before the Redemption Date to each holder of notes to be redeemed. If we elect to partially redeem the notes, the trustee will select in a fair and appropriate manner the notes to be redeemed.

    Unless we default in payment of the redemption price, on and after the Redemption Date, interest will cease to accrue on the notes or portions thereof called for redemption.

Merger, Consolidation or Sale of Assets

    Neither Harrah's Operating nor Harrah's Entertainment may consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to another corporation, person or entity unless:

immediately after giving effect to the transaction, no default or Event of Default shall exist under the indenture.

Events of Default

    "Event of Default" means with respect to the notes, any of the following:

    "Non-recourse Indebtedness" means indebtedness with terms providing that the lender's claim for repayment of that indebtedness is limited solely to a claim against the property that secures the indebtedness.

33


    "Consolidated Net Tangible Assets" means the total amount of assets (including investments in joint ventures) of Harrah's Operating and its subsidiaries (less applicable depreciation, amortization and other valuation reserves) after deducting therefrom:

    If an Event of Default with respect to notes (other than an Event or Default relating to certain events of bankruptcy, insolvency or reorganization) occurs and is continuing, either the trustee or the holders of at least 25% in principal amount of the outstanding notes may, by a notice as provided in the indenture, declare the unpaid principal amount of, and any accrued and unpaid interest on, all notes to be due and payable immediately. However, at any time after a declaration of acceleration with respect to notes has been made, but before the trustee obtains a judgment or decree based on that acceleration, the holders of a majority in principal amount of the outstanding notes may, under certain circumstances, rescind and annul that acceleration. For information regarding waiver of defaults, see "Modification and Waiver" below.

    The indenture will provide that, subject to the trustee's duty to act with the required standard of care during an Event of Default, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders, unless such holders offer the trustee reasonable security or indemnity. Subject to certain provisions of the indenture, including those entitling the trustee to receive security and indemnification, the holders of a majority in principal amount of the outstanding notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the notes.

    The indenture requires that we furnish annually to the trustee a statement as to our performance of our obligations under the indenture and as to any default in such performance.

Modification and Waiver

    We generally may amend the indenture or the notes with the written consent of the holders of a majority in principal amount of the outstanding notes. The holders of a majority in principal amount of the outstanding notes may also waive our compliance in a particular instance with any provision of the indenture with respect to the notes. We must obtain the consent of each holder of notes affected by a particular amendment or waiver, however, if such amendment or waiver:

34


    We may amend the indenture or the notes without notice to or the consent of any holder of a debt security:

    The holders of a majority in principal amount of the outstanding notes, by notice to the trustee, may waive any existing default or Event of Default and its consequences with respect to the notes other than a default or Event of Default in the payment of the principal of or any interest on any notes; provided, however, that the holders of a majority in principal amount of the outstanding notes may rescind an acceleration and its consequences, including any related payment default that resulted from the acceleration.

Additional Covenants Of Harrah's Operating

Limitation on Lien

    Neither Harrah's Operating nor any of its Subsidiaries may issue, assume or guarantee any Indebtedness secured by a Lien upon any Consolidated Property or on any Indebtedness or shares of capital stock of, or other ownership interests in, any Subsidiaries (regardless of whether the Consolidated Property, Indebtedness, capital stock or ownership interests were acquired before or after the date of the Indenture) without effectively providing that the notes shall be secured equally and ratably with (or prior to) such Indebtedness so long as such Indebtedness shall be so secured, except that this restriction will not apply to:

    (1) Liens existing on the date of original issuance of the notes;

35


    (2) Liens affecting property of a corporation or other entity existing at the time it becomes a Subsidiary of Harrah's Operating or at the time it is merged into or consolidated with Harrah's Operating or a Subsidiary of Harrah's Operating;

    (3) Liens on property existing at the time of acquisition thereof or to secure Indebtedness incurred prior to, at the time of, or within 24 months after the acquisition for the purpose of financing all or part of the purchase price thereof;

    (4) Liens on any property to secure all or part of the cost of improvements or construction thereon or Indebtedness incurred to provide funds for such purpose in a principal amount not exceeding the cost of such improvements or construction;

    (5) Liens which secure Indebtedness owing by a Subsidiary of Harrah's Operating to Harrah's Operating or to a Subsidiary of Harrah's Operating;

    (6) Liens securing Indebtedness of Harrah's Operating the proceeds of which are used substantially simultaneously with the incurrence of such Indebtedness to retire Funded Debt;

    (7) purchase money security Liens on personal property;

    (8) Liens securing Indebtedness of Harrah's Operating or any of its Subsidiaries the proceeds of which are used within 24 months of the incurrence of such Indebtedness for the cost of the construction and development or improvement of property of Harrah's Operating or any of its Subsidiaries;

    (9) Liens on the stock, partnership or other equity interest of Harrah's Operating or any of its Subsidiaries in any Joint Venture or any such Subsidiary which owns an equity interest in such Joint Venture to secure Indebtedness, provided the amount of such Indebtedness is contributed and /or advanced solely to such Joint Venture;

    (10) Liens to government entities, including pollution control or industrial revenue bond financing;

    (11) Liens required by any contract or statute in order to permit Harrah's Operating or a Subsidiary of Harrah's Operating to perform any contract or subcontract made by it with or at the request of a governmental entity;

    (12) mechanic's, materialman's, carrier's or other like Liens, arising in the ordinary course of business;

    (13) Liens for taxes or assessments and similar charges;

    (14) zoning restrictions, easements, licenses, covenants, reservations, restrictions on the use of real property and certain other minor irregularities of title; and

    (15) any extension, renewal, replacement or refinancing of any Indebtedness secured by a Lien permitted by any of the foregoing clauses (1) through (14).

    Notwithstanding the foregoing, Harrah's Operating and any one or more of its Subsidiaries may, without securing the notes, issue, assume or guarantee Indebtedness which would otherwise be subject to the foregoing restrictions in an aggregate principal amount which, together with all other such Indebtedness of Harrah's Operating and its Subsidiaries which would otherwise be subject to the foregoing restrictions (not including Indebtedness permitted by the preceding paragraph) and the aggregate Value of Sale and Lease-Back Transactions (other than those in connection with which Harrah's Operating has voluntarily retired Funded Debt) does not at any one time exceed 15% of Consolidated Net Tangible Assets of Harrah's Operating and its consolidated Subsidiaries.

36


Limitation on Sale and Lease-Back Transactions

    Neither Harrah's Operating nor any of its Subsidiaries will enter into any Sale and Lease-Back Transaction unless either (1) Harrah's Operating or such Subsidiary would be entitled, pursuant to the above provisions, to incur Indebtedness in a principal amount equal to or exceeding the Value of such Sale and Lease-Back Transaction, secured by a Lien on the property to be leased, without equally and ratably securing the notes or (2) Harrah's Operating within 120 days after the effective date of such Sale and Lease-Back Transaction applies to the voluntary retirement of its Funded Debt an amount equal to the Value of the Sale and Lease-Back Transaction (subject to credits for certain voluntary retirements of Funded Debt).

Guarantee of Notes

    Harrah's Entertainment will irrevocably and unconditionally guarantee, on an unsecured senior basis, the payment of all obligations of Harrah's Operating under the notes. If Harrah's Operating defaults in the payment of the principal of, premium, if any, or interest on such notes when and as the same shall become due, whether upon maturity, acceleration, call for redemption or otherwise, without the necessity of action by the trustee or any holder of such notes, Harrah's Entertainment shall be required promptly and fully to make such payment. The indenture provides for the release of Harrah's Entertainment as guarantor of the notes in certain circumstances, including circumstances in which:

    Harrah's Entertainment conducts substantially all of its business through Harrah's Operating and its subsidiaries and does not own any material assets other than the common stock of Harrah's Operating. As such, Harrah's Entertainment is dependent on the receipt of dividends or other payments from Harrah's Operating to make payments on the guarantee of the notes. Our credit facility imposes significant restrictions on Harrah's Operating's ability to pay dividends to Harrah's Entertainment.

Limited Liability of Certain Persons

    None of the past, present or future stockholders, incorporators, employee officers or directors, as such, of Harrah's Operating, Harrah's Entertainment or any of our affiliates or successor corporations shall have any personal liability in respect of our obligations under the indenture or the debt securities by reason of his, her or its status as such stockholder, incorporator, employee officer or director.

Mandatory Disposition Pursuant to Gaming Laws

    Federal, state and local authorities in several jurisdictions regulate extensively our casino entertainment operations. The nature of such regulation is described in detail in "Business and Properties—Governmental Regulation" in the 2000 Form 10-K of Harrah's Entertainment, which we have incorporated by reference herein. The gaming authority of any jurisdiction in which we or any of our subsidiaries conduct or propose to conduct gaming may require that a holder of the notes or the beneficial owner of the notes of a holder be licensed, qualified or found suitable under applicable gaming laws. Under the indenture, each person that holds or acquires beneficial ownership of any of the notes shall be deemed to have agreed, by accepting such notes, that if any such gaming authority requires such person to be licensed, qualified or found suitable under applicable gaming laws, such

37


holder or beneficial owner, as the case may be, shall apply for a license, qualification or a finding of suitability within the required time period.

    If a person required to apply or become licensed or qualified or be found suitable fails to do so, we shall have the right, at our election, (1) to require such person to dispose of its notes or beneficial interest therein within 30 days of receipt of notice of such election or such earlier date as may be requested or prescribed by such gaming authority or (2) to redeem such notes at a redemption price equal to the lesser of:

No Protection in the Event of a Change of Control

    The notes do not contain any provisions which may afford holders of the notes protection in the event either Harrah's Operating or Harrah's Entertainment has a change of control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control) which could adversely affect holders of the notes.

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

Defeasance and Discharge

    The indenture provides that we may be discharged from any and all obligations in respect of the notes, except for certain obligations to pay additional amounts, if any, upon the occurrence of certain tax, assessment or governmental charge events with respect to payments on such notes, to register the transfer or exchange of notes, to replace stolen, lost or mutilated notes, to maintain paying agencies and to hold money for payment in trust. We will be so discharged when we:

Book-Entry, Delivery and Form

    The notes will be represented by one or more permanent global notes in definitive, fully registered form without interest coupons and will be deposited with the trustee as custodian for, and registered in the name of a nominee of, DTC.

    Ownership of beneficial interests in a global note will be limited to persons who have accounts with DTC ("participants") or persons who hold interests through participants. Ownership of beneficial

40


interests in a global note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants).

    So long as DTC, or its nominee, is the registered owner or holder of the notes, DTC or that nominee, as the case may be, will be considered the sole owner or holder of the notes represented by the global note for all purposes under the indenture and the notes. No beneficial owner of an interest in a global note will be able to transfer that interest except in accordance with DTC's applicable procedures, in addition to those provided for under the indenture and, if applicable, those of Euroclear and Clearstream Banking.

    Payments of the principal of, and interest on, a global note will be made to DTC or its nominee, as the case may be, as the registered owner thereof. Neither we, the trustee nor any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

    We expect that DTC or its nominee, upon receipt of any payment of principal or interest in respect of a global note, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global note as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in such global note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

    Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream Banking will be effected in the ordinary way in accordance with their respective rules and operating procedures.

    We expect that DTC will take any action permitted to be taken by a holder of notes (including the presentation of notes for exchange as described below) only at the direction of one or more participants to whose account DTC interests in a global note is credited and only in respect of such portion of the aggregate principal amount of notes as to which such participant or participants has or have given such direction. However, if there is an Event of Default under the notes, the Depository Trust Company will exchange the applicable global note for certificated notes, which it will distribute to its participants.

    We understand that: DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "Clearing Agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Indirect access to DTC system is available to others such as banks, brokers, dealers and trust companies and certain other organizations that clear through or maintain a custodial relationship with a participant, either directly or indirectly ("indirect participants").

    Although DTC, Euroclear and Clearstream Banking are expected to follow the foregoing procedures in order to facilitate transfers of interests in a global note among participants of DTC, Euroclear and Clearstream Banking, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither we nor the Trustee will

41


have any responsibility for the performance by DTC, Euroclear or Clearstream Banking or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

    If DTC is at any time unwilling or unable to continue as a depositary for the global notes and a successor depositary is not appointed by us within 90 days, we will issue certificated notes in exchange for the global notes. Holders of an interest in a global note may receive certificated notes in accordance with DTC's rules and procedures in addition to those provided for under the indenture.

Same Day Settlement and Payment

    We will make payments in respect of the notes represented by the global notes (including principal, premium, if any, interest and liquidated damages, if any) by wire transfer of immediately available funds to the accounts specified by the global note holder. We will make all payments of principal, interest and premium and liquidated damages, if any, with respect to certificated notes by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no account is specified, by mailing a check to that holder's registered address. The notes represented by the global notes are expected to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in the notes will, therefore, be required by DTC to be settled in immediately available funds. We expect that secondary trading in any certificated notes will also be settled in immediately available funds.

    Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a global note from a participant in DTC will be credited, and any crediting of this type will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a global note by or through a Euroclear or Clearstream participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC's settlement date.

The Trustee

    The trustee under the indenture is U.S. Bank, N.A. (formerly known as Firstar Bank, N.A.).

Governing Law

    The indenture and the notes will be governed by, and construed in accordance with, the internal laws of the state of New York.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

    The following discussion is a summary of the material United States federal income tax consequences relevant to the exchange of private notes for exchange notes, and the ownership and disposition of the notes, but does not purport to be a complete analysis of all potential tax effects. The discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), United States Treasury Regulations issued thereunder, Internal Revenue Service rulings and pronouncements and judicial decisions now in effect, all of which are subject to change at any time. Any such change may be applied retroactively in a manner that could adversely affect a holder of the notes. This discussion does not address all of the United States federal income tax consequences that may be relevant to a holder in light of such holder's particular circumstances or to holders subject to special rules, such as certain financial institutions, U.S. expatriates, insurance companies, dealers in securities or currencies, traders in securities, holders whose functional currency is not the U.S. dollar, tax-exempt organizations and persons holding the notes as part of a "straddle," "hedge," "conversion transaction" or other integrated transaction. If a partnership holds notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding notes, you should consult your own tax advisors. Moreover, the effect of any applicable state, local or foreign tax laws is not discussed. The discussion deals only with notes held as "capital assets" within the meaning of Section 1221 of the Code.

    As used herein, "United States Holder" means a beneficial owner of the notes who or that is:

    We have not sought and will not seek any rulings from the Internal Revenue Service (the "IRS") with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences of the purchase, ownership or disposition of the notes or that any such position would not be sustained.

    Prospective investors should consult their own tax advisors with regard to the application of the tax consequences discussed below to their particular situations as well as the application of any state, local, foreign or other tax laws, including gift and estate tax laws.

United States Holders

Exchange of Notes Pursuant to Exchange Offer

    The exchange of private notes for exchange notes should not constitute a taxable exchange. As a result, (1) a United States Holder should not recognize a taxable gain or loss as a result of exchanging such holder's notes; (2) the holding period of the notes received should include the holding period of the notes exchanged therefor; and (3) the adjusted tax basis of the notes received should be the same as the adjusted tax basis of the notes exchanged therefor immediately before such exchange.

43


Interest

    Payments of stated interest on the notes generally will be taxable to a United States Holder as ordinary income at the time that such payments are received or accrued, in accordance with such United States Holder's method of accounting for United States federal income tax purposes.

Market Discount

    The market discount rules discussed below apply to any note purchased after original issue at a price less than its stated redemption price at maturity.

    If a United States Holder purchases a note at a market discount, such holder generally will be required to treat any principal payments on, or any gain on the disposition of, such note as ordinary income to the extent of the accrued market discount (not previously included in income) at the time of such payment or disposition. In general, subject to a de minimis exception, market discount is the amount by which the note's stated redemption price at maturity exceeds the holder's basis in the note immediately after the note is acquired. A note is not treated as purchased at a market discount, however, if the market discount is less than 0.25 percent of the stated redemption price at maturity of the note multiplied by the number of complete years to maturity from the date when you acquired the note. Market discount on a note will accrue on a straight-line basis, unless a holder elects to accrue such discount on a constant yield to maturity basis. This election is irrevocable. A United States Holder may also elect to include market discount in income currently as it accrues. This election, once made, applies to all market discount obligations acquired on or after the first day of the first taxable year to which the election applies and may not be revoked without the consent of the IRS. If a United States Holder acquires a note at a market discount and disposes of such note in any non-taxable transaction (other than a nonrecognition transaction defined in section 1276(c) of the Code), accrued market discount will be includable as ordinary income to such holder as if such holder had sold the note at its fair market value. A United States Holder may be required to defer until the maturity of the note or, in certain circumstances, its earlier disposition the deduction of all or a portion of the interest expense attributable to debt incurred or continued to purchase or carry a note with market discount, unless an election to include the market discount in income on a current basis is made.

Amortizable Bond Premium

    If a United States Holder purchases a note for an amount in excess of its stated redemption price at maturity, such holder will generally be considered to have purchased the note with "amortizable bond premium." The amount of amortizable bond premium is computed based on the redemption price on an earlier call date if such computation results in a smaller amortizable bond premium attributable to the period of such earlier call date. A United States Holder generally may elect to amortize such premium using the constant yield to maturity method. The amount amortized in any year will generally be treated as a reduction of your interest income on the note. If the amortizable bond premium allocable to a year exceeds the amount of interest allocable to that year, the excess would be allowed as a deduction for that year but only to the extent that a holder's prior interest inclusions exceed bond premium deductions on the note. If a United States Holder does not make such an election, the premium on a note will decrease the gain or increase the loss otherwise recognized on the sale, redemption, retirement or other disposition of the note. The election to amortize the premium on a constant yield to maturity method, once made, generally applies to all bonds held or subsequently acquired by a United States Holder on or after the first day of the first taxable year to which the election applies. A United States Holder may not revoke this election without the consent of the IRS.

Sale or Other Taxable Disposition of the Notes

    A United States Holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note equal to the difference between the amount realized upon the disposition (less a portion allocable to any accrued and unpaid interest, which will be taxable as ordinary income) and the United States Holder's adjusted tax basis in the note. A United States Holder's adjusted tax basis in a note generally will be the United States Holder's cost therefor, plus market discount previously included in income, if any, less any previous bond premium deductions and any principal payments received by such holder. This gain or loss generally will be a capital gain or loss, and will be a long-term capital gain or loss if the United States Holder has held the note for more than one year. Otherwise, such gain or loss will be a short-term capital gain or loss.

Backup Withholding and Information Regarding

    A United States Holder may be subject to a backup withholding tax when such holder receives interest and principal payments on the notes held or upon the proceeds received upon the sale or other disposition of such notes before maturity. Certain holders (including, among others, corporations and certain tax-exempt organizations) are generally not subject to backup withholding. Payments made in respect of a note must be reported to the IRS, unless you are an exempt recipient or otherwise establish an exemption from information reporting. A United States Holder will be subject to backup withholding if such holder is not otherwise exempt and such holder:

    United States Holders should consult their own tax advisor regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. The backup withholding tax is not an additional tax and any amount withheld is allowable as a refund or credit against a United States Holder's federal income tax liability as long as certain information is provided to the IRS.

Non-United States Holders

    A non-United States Holder is a beneficial owner of the notes who is not a United States Holder.

Exchange of Notes Pursuant to Exchange Offer

    The material federal income tax consequences to a non-United States Holder of an exchange of private notes for exchange notes will be the same as those described for United States Holders under "—United States Holders—Exchange of Notes Pursuant to Exchange Offer."

Interest

    Interest paid to a non-United States Holder will not be subject to United States federal withholding tax provided that:

    The certification requirement described above may require a non-United States Holder that provides an IRS form, or that claims the benefit of an income tax treaty, to also provide its United States taxpayer identification number. The applicable regulations generally also require, in the case of a note held by a foreign partnership, that:

Further, a look-through rule will apply in the case of tiered partnerships. In addition, special rules apply to qualified intermediaries that enter into withholding agreements with the IRS, and such intermediaries generally are not required to forward any certification forms received from you. Prospective investors should consult their own tax advisors regarding the certification requirements for non-United States persons.

    Interest on notes not excluded from United States withholding tax as described above generally will be subject to United States withholding tax at a 30% rate, except where an applicable United States income tax treaty provides for the reduction or elimination of such withholding tax (and you provide the appropriate certification) or if, as described more fully below, interest on the notes is effectively connected with your conduct of a trade or business in the United States.

Sale or Other Disposition of the Notes

    A non-United States Holder will generally not be subject to United States federal income tax or withholding tax on gain recognized on the sale, exchange, redemption, retirement or other disposition of a note. However, a non-United States Holder may be subject to tax on such gain if such holder is an individual who was present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met, in which case such holder may have to pay a United States federal income tax of 30% (or, if applicable, a lower treaty rate) on such gain.

Income or Gain Effectively Connected With a United States Trade or Business

    If interest or gain from a disposition of the notes is effectively connected with a non-United States Holder's conduct of a United States trade or business or, if an income tax treaty applies, and the non-United States Holder maintains a United States "permanent establishment" to which the interest or gain is generally attributable, the non-United States Holder may be subject to United States federal income tax on the interest or gain on a net basis in the same manner as if it were a United States Holder. If interest income received with respect to the notes is taxable on a net basis, the 30% withholding tax described above will not apply (assuming an appropriate certification is provided). A foreign corporation that is a holder of a note also may be subject to a branch profits tax equal to 30%

46


of its effectively connected earnings and profits for the taxable year, subject to certain adjustments, unless it qualifies for a lower rate under an applicable income tax treaty.

Backup Withholding and Information Reporting

    Backup withholding and information reporting will generally not apply to payments made by us or our paying agents, in their capacities as such, to a non-United States Holder if the holder has provided the required certification that it is not a United States person as described above, provided that neither we nor our paying agent has actual knowledge that the holder is a United States person. Payments of the proceeds from a disposition by a non-United States Holder of a note made to or through a foreign office of a broker will generally not be subject to information reporting or backup withholding, except that information reporting may apply to those payments if the broker has a certain type of relationship to the United States. Payment of the proceeds from a disposition by a non-United States Holder of a note made to or through the United States office of a broker is generally subject to information reporting and backup withholding unless the beneficial owner appropriately certifies as to its foreign status or otherwise establishes an exemption from information reporting and backup withholding.

    Non-United States Holders should consult their own tax advisors regarding the application of backup withholding in their particular circumstance and the availability of and procedure for obtaining an exemption from backup withholding under current Treasury regulations. Any amounts withheld under the backup withholding rules from a payment to a non-United States Holder will be allowed as a refund or a credit against the holder's United States federal income tax liability, provided that the required information is furnished to the IRS.

    THE PRECEDING DISCUSSION OF MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. ACCORDINGLY, YOU ARE URGED TO CONSULT WITH YOUR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO YOU OF THE EXCHANGE OFFER AND THE OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE EFFECT AND APPLICABILITY OF STATE, LOCAL, FOREIGN OR OTHER TAX LAWS, AS WELL AS THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

PLAN OF DISTRIBUTION

    Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale, offer to resell or other transfers of such exchange notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of exchange notes received in exchange for private notes where such private notes were acquired as a result of market-making activities or other trading activities. We have agreed that, starting on the expiration date and ending on the close of business one year after the expiration date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

    We will not receive any proceeds from any sale of exchange notes by brokers-dealers or any other persons. Exchange notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the exchange notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such exchange notes. Any broker-dealer that resells exchange notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such exchange notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit of any such resale of exchange notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

    For a period of one year after the expiration date, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holder of the private notes) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the private notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

    By its acceptance of the exchange offer, any broker-dealer that receives exchange notes pursuant to the exchange offer agrees to notify us before using this prospectus in connection with the sales or transfer of the exchange notes. The broker-dealer further acknowledges and agrees that, upon receipt of notice from us of the happening of any event which:

which notice we agree to deliver promptly to the broker-dealer, the broker-dealer will suspend use of this prospectus until we have notified the broker-dealer that delivery of the prospectus may resume and have furnished copies of any amendment or supplement to this prospectus to the broker-dealer.
