Item 5.  Other Events.

         On December 7, 1999 the Board of Directors of Black Hawk Gaming &
Development Company, Inc. ("Company") adopted an amendment in the form attached
hereto to modify the Understanding as to Joint Venture Agreement dated November
12, 1996 ("Understanding").

         The Understanding required the Company to offer a participation of up
to 49% to Diversified Opportunities Group Ltd. ("DOGL") in any gaming
opportunity undertaken by the Company. DOGL is an affiliate of Jeffrey P.
Jacobs, the Company's Chairman, Chief Executive Officer and largest beneficial
shareholder. That right of participation has been terminated, although DOGL must
continue to offer a 51% participation to the Company in gaming opportunities
undertaken by DOGL, except slot or video poker routes (including those in
restaurants, grocery stores and truck stops) or in the business of wagering
related to a pari-mutuel license, whether at live tracks, by satellite or
otherwise.

         Finally, the amendment provides that the Company's right to participate
in DOGL's gaming opportunities not excepted above will terminate one year after
Jeffrey P. Jacobs ceases to be an officer and director of the Company and ceases
to own beneficially sufficient shares of the Company to elect a majority of its
directors.
