摘要： A method and apparatus for securing the game program software and related data files used by a gaming device and for authenticating such files during game startup and play. In one embodiment of the present invention, a verification code is generated by the manufacturer for each software file and data file used by the game. The verification codes are stored in a non-volatile, tamper-proof, read-only memory device securely attached to the gaming device. On the occurrence of certain pre-defined events, the stored verification code is used to validate the game software and data files. Verification consists of calculating a live verification code for some or all of the software and data files present in the alterable random access memory using the same method chosen to create the stored verification code. In some embodiments of the present invention, the verification code is the result of a hash function of trusted copies of each software and related data file.

摘要： The preferred embodiment of the present invention operates on a system of interconnected gaming machines and selectively provides one or more active features to all of the gaming machines linked to the system. The enablement of the feature may be based on the combined results from previous plays on the individual gaming machines. The feature may be a bonus award for a specific displayed combination, an increased possibility for a winning combination, or any other feature which alters the normal operation of the gaming machines. The first machine to generate a winning game result to which the feature applies will be given an award based upon the feature. The feature is then disabled and the system returns to normal play mode until the feature is again enabled. Various other features are described.

摘要： A method and apparatus for securing the game program software and related da ta files used by a gaming device and for authenticating such files during game startup and play. In one embodiment of the present invention, a verification code is generated by the manufacturer for each software file and data file used by the game. The verification codes are stored in a non-volatile, tampe r- proof, read-only memory device, which is (in some embodiments) securely attached to the gaming device. On some or every download of the game softwar e and/or related data files into the gaming device, commencement of a game, or on the occurrence of certain pre-defined events, the stored verification cod e is used to validate the game software and data files. In some embodiments, verification is performed automatically on a periodic basis without operator or player action. Verification consists of calculating a live verification code for some or all of the software and data files present in the alterable random access memory using the same method chosen to create the stored verification code. In some embodiments of the present invention, the verification code is the result of a hash function of trusted copies of each software and related data file. If the live code matches the stored code for every suspect file, then operation and play proceeds normally. If, however, one or more codes do not match, an error condition is declared, operation is halted, and notification of the error condition follows.

Additional jackpots accumulate at higher rates. The betting of additional monetary amounts enables the player to win additional jackpots. This provides added incentive for the player to bet additional monetary amounts.

摘要： In one embodiment of a gaming machine incorporating the present invention, a special outcome of a primary game initiates a bonus game of a type very different from the primary game. One of the outcomes of the bonus game is the initiation of a third game, which the player then plays to determine whether the bonus game ends o r continues. This third game may be the random selection by the player or the gaming machine of one of a plurality of tiles (or other icons), where certain ones of the tiles end the bonus game and other ones of the tiles allow the bonus game to continue. The third game may be any game where a random result determines the ending of the bonu s game, or the third game may be a game of skill, such as a hand of blackjack. In on e embodiment, the primary game, the bonus game, and the third game are played on the same touch video screen, where sensors in the screen detect the position of a player's touch in order to select a displayed option.

摘要： The preferred embodiment of the present invention operates on a system of interconnected gaming machines. In a normal operation mode, the individual machines provide awards to individual players based on the generation of symbol combinations in a first group of symbol combinations. The linked gaming machines are polled by a feature controller to determine whether symbol combinations in a second group of combinations are generated. These symbol combinations in the second group of combinations are accumulated until a level is reached such that a bonus award will be given to the next player whose machine generates a symbol combination within said second group of symbol combinations. The first machine to generate a winning symbol combination within said second group of symbol combinations is given a bonus award. The feature is then reset. The status of the feature is displayed for all players of the linked gaming machines.
