Management Agreement [Member]
Operating agreement description for camc			On June 19, 1993, two subsidiaries of Diamondhead Casino Corporation, Casino World Inc. and Mississippi Gaming Corporation, entered into a Management Agreement with Casinos Austria Maritime Corporation (CAMC). Subject to certain conditions, under the Management Agreement, CAMC would operate, on an exclusive basis, all of the Company's proposed dockside gaming casinos in the State of Mississippi, including any operation fifty percent (50%) or more of which is owned by the Company or its affiliates. Unless terminated earlier pursuant to the provisions of the Agreement, the Agreement terminates five years from the first day of actual Mississippi gaming operations and provides for the payment of an annual operational term management fee of 1.2% of all gross gaming revenues between zero and $100,000,000; plus 0.75% of gross gaming revenue between $100,000,000 and $140,000,000; plus 0.5% of gross gaming revenue above $140,000,000; plus two percent of the net gaming revenue between zero and $25,000,000; plus three percent of the net gaming revenue above twenty-five million dollars $25,000,000. Management of the Company believes this Agreement is no longer in effect. However, there can be no assurance that CAMC will not attempt to maintain otherwise which would lead to litigation.
