MEMORANDUM OF UNDERSTANDING

     THIS MEMORANDUM OF UNDERSTANDING ("Memorandum") is entered and effective 
this 29th day of October, 1997 by and among Boardwalk Casino, Inc., a Nevada 
corporation ("Boardwalk"), Diversified Opportunities Group Ltd, an Ohio 
limited liability company ("Diversified"), Jacobs Entertainment Nevada, Inc., 
a Nevada corporation, or its nominee ("Jacobs") and Avis P. Jansen, a Nevada 
resident ("Jansen") under the following circumstances:

     A.  Boardwalk needs an immediate capital infusion of $3.25 Million to 
         pay interest due on its $40 Million Note Indenture dated as of April 
         7, 1995 between Boardwalk, as Issuer and Shawmut Bank, N.A., as Trustee
         (the "Note Indenture") and retire an outstanding $600,000 obligation 
         and is in need of substantial additional assistance in order to improve
         the financial results of its current business.

     B.  Jacobs is willing to purchase $2.65 Million and Jansen is willing to 
         purchase $600,000 of 6% non-voting cumulative preferred stock of 
         Boardwalk.

     C.  Jacobs has under consideration up to an additional $15 Million 
         investment in Boardwalk and the construction of a development on the 
         office building property currently leased by Boardwalk from Jansen that
         is intended to enhance Boardwalk's gaming and hotel operations.

     D.  Boardwalk and Jansen are interested in providing Jacobs with the 
         means to develop the office building property in a manner that will 
         be beneficial to Boardwalk.

     NOW, THEREFORE, the parties agree as follows:

1.   ISSUANCE OF PREFERRED STOCK AND RELINQUISHMENT OF RIGHTS TO COMMON STOCK
     1.1  On or before October 29, 1997, Boardwalk will issue and Jacobs and 
          Jansen will purchase at a price of $1,000 per share, 6% Non-voting 
          Cumulative Preferred Share, Series A of Boardwalk ("Preferred 
          Shares"), containing the terms described in Exhibit A attached hereto.
          The number of shares and the consideration for each purchaser are set 
          forth in



          the following table:

              Purchaser          Shares Purchased         Consideration
              ---------          ----------------         -------------
              Jacobs                  2,650               $2.65 Million
              Jansen                    600               $600,000

     1.2  The proceeds of the sale of Preferred Shares together with existing 
working capital of Boardwalk will be used to pay the current interest payment 
due on the Note Indenture and the outstanding $600,000 note payable to David 
Cordova.

     1.3  Diversified hereby relinquishes its right to convert all or any 
portion of the unpaid principal balance of the $5,000,000 Convertible 
Subordinated Note issued on September 24, 1996 by Boardwalk to Diversified 
into shares of common stock of Boardwalk, $.001 par value per share and 
Boardwalk accepts such relinquishment and hereby cancels such conversion 
right.

2.   JACOBS OPTION FOR BOARDWALK PREFERRED SHARES
     2.1  Upon the initial purchase of the Preferred Shares, Boardwalk will 
          grant to Jacobs an option (the "Option") to acquire up to an 
          additional 15,000 Preferred Shares at a purchase price of $1000 per 
          share, such option to remain outstanding for a period of two (2) 
          years.

     2.2  As long as the Option is outstanding, Boardwalk will not extend, 
          change the strike price or otherwise change any of the terms of any of
          the warrants for Boardwalk common stock outstanding on the date the 
          Option is granted, including, without limitation, the warrants 
          expiring in February, 1998.

3.   OFFICE BUILDING OPTION AND LEASE MODIFICATION
     3.1  In consideration of Jacob's commitment of time and resources to 
          explore the feasibility of a development with a total cost in excess 
          of $20 Million on the site of the adjoining office building currently 
          leased by Boardwalk from the Norbert W. Jansen and Avis Jansen Family 
          Trust (the "Family Trust") under a Lease Agreement effective October 
          1, 1996 (the "Lease"), Jansen will grant to Jacobs a purchase option 
          (the "Purchase

                                      -2-




          Option") to purchase the premises leased under the Lease (the "Office
          Building Property") on the following terms and conditions:

          3.1.1  The purchase price for the Office Building Property is $10
                 Million in cash or other form of same day funds.

          3.1.2  The Purchase Option must be exercised by written notice to 
                 Jansen no later than November 1, 1998 (the "Exercise Date") 
                 and the closing of the purchase and payment of the purchase 
                 price shall occur on January 3, 1999 (the "Closing Date").

          3.1.3  On the Exercise Date Jacobs shall deposit $500,000 as earnest
                 money with National Title Company, as escrow agent, to be
                 applied toward the payment of the Purchase Price. The earnest
                 money will be forfeited if Jacobs fails to close on the
                 Closing Date for any reason other than the failure of Jansen
                 to convey the title to the Office Building Property, provide 
                 title insurance, pay closing costs, deliver closing documents 
                 or prorate rent in accordance with the requirements of 
                 Section 32 of the Lease.

     3.2  Jansen and Boardwalk hereby agree that the Lease will be modified as
          follows:
          3.2.1  Commencing November 1, 1997 Boardwalk will have the right to
                 defer payment of up to $40,000 per month of the Base Rent due
                 under the Lease. If the Purchase Option is not exercised the
                 deferred Base Rent will be due November 1, 1998 and the right
                 to defer payment will terminate. If the Purchase Option is
                 exercised the deferred Base Rent will be due on the Closing
                 Date.
          3.2.2  Boardwalk's option and right of first refusal to purchase
                 the Office Building Property in Section 32 of the Lease will
                 be subject to and subordinate to the Purchase Option and will
                 terminate upon the closing of the Purchase Option by Jacobs.

     3.3. The Option and Proxy Agreement among Norbert W. Jansen,
          individually and as trustee of the Family Trust, Diversified and
          Boardwalk dated September 24, 1996 (the "Jansen Shares Agreement")
          will be deemed to be amended to provide that:
          3.3.1  The phrase "1,000,000 shares" in paragraphs 1(c) and 1(d)
                 will be changed to "1,734,620 shares" and the exercise price
                 for the shares subject to paragraph 1(c) of

                                      -3-


                 the Jansen Shares Agreement will be changed to $4.00 per
                 share and the exercise price for the shares described in
                 paragraph 1(d) will be changed to $4.00 per share.
          3.3.2  If the Purchase Option is not exercised, then on and after
                 the Exercise Date the phrase "1,734,620 shares" in paragraphs
                 1(c) and 1(d) will revert to "1,000,000 shares".
          3.3.3  In the event a merger, consolidation or sale of all or
                 substantially all of the assets of Boardwalk to Jacobs is
                 presented for shareholder approval and Jansen votes the shares
                 she directly or beneficially owns against such transaction, the
                 exercise price for the shares subject to option as described in
                 subparagraphs (a) and (b) above will be $1.00 per share.
          3.3.4. The rights granted to purchase shares under the Jansen
                 Shares Agreement will apply to any shares received in exchange
                 for the shares subject to the Jansen Shares Agreement in any
                 merger, consolidation or sale transaction.

4.   DEVELOPMENT PROJECT
     4.1  Jacobs will undertake a preliminary analysis of the feasibility of
          building and financing a development on the Office Building Property
          (the "Project") and channeling patrons of the Project into the
          Boardwalk gaming facilities. Upon completion of the feasibility
          analysis, Jacobs will share the results with the Boardwalk Board of
          Directors and after having the benefit of Boardwalk's input, decide
          whether to pursue the Project. Boardwalk agrees that until a decision
          has been made by Jacobs as to whether to proceed with the Project, it
          will not convey, transfer or encumber the Boardwalk tangible assets or
          otherwise take any action with respect to the Boardwalk tangible
          assets that will interfere or negatively impact upon the prospects for
          the Project. If Boardwalk violates the provisions of this Section 4.1,
          then Boardwalk shall within ten (10) days of such occurrence, pay to
          Jacobs in cash, a termination fee of $2 Million as reimbursement for
          Jacobs' expenses relative to the transactions contemplated by this
          Memorandum of Understanding and as full and complete liquidation of
          all damages.

     4.2  If Jacobs elects to go forward with the Project, the Board of
          Directors of Boardwalk will

                                      -4-



          entertain at that time or such later time selected by Jacobs, not to
          exceed two (2) years from completion of the feasibility study for
          the Project, a proposal from Jacobs to merge, consolidate or sell
          all or substantially all of the assets of Boardwalk to Jacobs at a
          price and on terms to be negotiated at the time the proposal is
          made; provided, that if the proposed transaction is a merger or
          consolidation with Black Hawk Gaming & Development Co., Inc. ("Black
          Hawk"), the ratio of Boardwalk shares to Black Hawk shares, based on
          their respective outstanding shares shall not be greater than 2
          shares of Boardwalk for 1 share of Black Hawk.

                                   EXHIBIT A

                          BOARDWALK PREFERRED SHARES

     Pursuant to the authority granted under Section 3.2 of the Company's 
Restated Articles of Incorporation, the Board of Directors does hereby 
authorize the issuance, from the Company's authorized but unissued Preferred 
Shares, of up to 18,250 Preferred Shares, par value of $.001, such Preferred 
Shares to be designated as "6% Non-voting Cumulative Preferred Shares, Series 
A", which shall have the powers, preferences and rights, and be subject to 
the qualifications, limitations and restrictions, set forth below.

                                       1

     DESIGNATION OF NEW PREFERRED SHARES.  The new Preferred Shares shall 
bear the designation "6% Non-voting Cumulative Preferred Shares, Series A".

                                       2

     NUMBER OF PREFERRED SHARES; CONSIDERATION.  The Company may issue up to 
a maximum of 18,250 shares of 6% Non-voting Cumulative Preferred Shares, 
Series A.  After the issuance of any 6% Non-voting Cumulative Preferred Shares, 
Series A, the Company shall not authorize or issue any Preferred Shares or 
other equity securities which are not junior to the 6% Non-voting Cumulative 
Preferred Shares, Series A with respect to dividends and upon liquidation, 
without first having obtained the written consent to such issuance of the 
holders of a majority of the 6% Non-voting Cumulative Preferred Shares, 
Series A then outstanding.

                                       3

     DIVIDENDS.  Holders of record of 6% Non-voting Cumulative Preferred Shares,
Series A shall be entitled to receive, when and as declared by the Board of 
Directors of the Company out of funds legally available for the payment of 
dividends, cumulative dividends at the annual rate of $60 per share, and no 
more.  Such dividends with respect to any share of 6% Non-voting Cumulative 


                                    -8-



Preferred Shares, Series A shall accrue (whether or not declared) from the 
date of issue thereof and shall be payable on the last business day of each 
December (herein after referred to as a "Dividend Payment Date") to persons who
are holders of record of any 6% Non-voting Cumulative Preferred Shares, 
Series A on the immediately preceding December 15.

     So long as any of the 6% Non-voting Cumulative Preferred Shares, Series 
     A are outstanding, the Company will not declare or pay or set apart for 
     payment any dividends (other than a dividend in Common Stock or in any 
     other class of stock ranking junior to the 6% Non-voting Cumulative 
     Preferred Shares, Series A both as to dividends and upon liquidation) or 
     make any other distribution on any class of Company stock ranking junior 
     to the 6% Non-voting Cumulative Preferred Shares, Series A either as to 
     dividends or upon liquidation and will not redeem, purchase or otherwise 
     acquire for value, or set apart money for any sinking or other analogous 
     fund for the redemption or purchase of any shares of any such junior class
     unless (a) all dividends on the 6% Non-voting Cumulative Preferred Shares,
     Series A for all Dividend Payment Dates prior to or concurrent with the 
     payment with respect to any such dividend, distribution, redemption, 
     purchase or acquisition as to such junior class (in any such case, a 
     "Junior Payment"), and if the Junior Payment does not occur on a Dividend
     Payment Date for the 6% Non-voting Cumulative Preferred Shares, Series A,
     for the next succeeding Dividend Payment Date, shall have been paid, and 
     (b) the Company is then in compliance with its obligations, if any, with 
     respect to the redemption of the 6% Non-voting Cumulative Preferred Shares,
     Series A pursuant to the provisions of paragraph 5 below.  Notwithstanding
     the foregoing provisions limiting redemption or purchase of the junior 
     securities described above, the Company may make such a redemption or 
     purchase upon first obtaining the written consent thereto of the holders 
     of a majority of the 6% Non-voting Cumulative Preferred Shares, Series A 
     then outstanding.

                                       4

     LIQUIDATION PREFERENCE.  The 6% Non-voting Cumulative Preferred Shares, 
Series A shall be preferred over the Company's Common Shares and any other 
series of Preferred Shares hereafter created by the Company as to assets so 
that in the event of any liquidation, dissolution or winding-up


                                     -9-



of the Company, whether voluntary or involuntary, the holders of the 6% 
Non-Voting Cumulative Preferred Shares, Series A shall be entitled to receive 
on a ratable basis out of the assets of the Company available for 
distribution to its shareholders, whether from capital, surplus or earnings, 
before any distribution is made to holders of Common Shares or any other 
series of Preferred Shares, an amount equal to $1,000 per share, plus all 
dividends and distributions accrued and unpaid on the 6% Non-voting 
Cumulative Preferred Shares, Series A to the date payment is made.  If upon 
any liquidation, dissolution or winding-up of the Company, the assets of the 
Company, or the proceeds thereof, distributable among the holders of the 6% 
Non-voting Cumulative Preferred Shares, Series A are insufficient to pay in 
full the preferential amount aforesaid, then such assets, or proceeds 
thereof, shall be distributed among such holders ratably in accordance with 
the respective amount which would be payable on such shares if all amounts 
payable thereon were paid in full.  For purposes of this paragraph 4, neither 
the voluntary sale, lease, conveyance, exchange or transfer (for cash, shares 
of stock, securities or other consideration) of all or substantially all the 
property or assets of the Company, nor the consolidation or merger of the 
Company with one or more companies, shall be deemed to be a liquidation, 
dissolution or winding-up, voluntary or involuntary, unless such voluntary 
sale, lease, conveyance, exchange or transfer shall be in connection with a 
plan of liquidation, dissolution or winding-up of the Company.

                                       5

     REDEMPTION RIGHTS.  On or after April 1, 2005 the 6% Non-voting 
Cumulative Preferred Shares, Series A shall be permitted to be redeemed by 
the Company upon the written request of any holder thereof for a redemption 
price of $1,000 per share, plus all accrued, unpaid dividends, whether 
declared or undeclared, through the date when the redemption price for the
