    摘要： A method of gaming comprises the steps of acquiring first biometric data of a game player by observing the game player through a button (14) of the gaming machine (10) when touched by game player, in which the button (14) also serves in operation of the gaming of the gaming machine (10). The first biometric data is compared with second biometric data provided by another source, for example, a 'smart card' carried by the game player. Then, the gaming machine (10) is activated for play by the game player if the first and second biomeric data have a close similarity.

    摘要： A method and apparatus of dynamically storing critical data of a gaming machine by allocating and deallocating memory space in a gaming machine is disclosed. One or more embodiments describe downloading or removing a new game to a gaming machine such that all existing critical data in NV-RAM memory is left intact. In one embodiment, the invention discloses a method and apparatus for dynamically allocating and deallocating memory space to accommodate either permanent or temporary storage in an NV-RAM. A method and apparatus is provided to monitor available memory space and dynamically resize the memory in NV-RAM. In one embodiment, a method is disclosed for performing an integrity check of the NV-RAM and determining whether a critical data error has occurred. In one or more embodiments, methods of compacting and shifting contents of an NV-RAM are described to consolidate available memory space or to prevent unauthorized access of NV-RAM memory.

    摘要： Gaming device (100), a base game, starts and has first bonus game (102). Once a player has inserted an appropriate amount of money, a player spins the reels (104). The gaming device (10) determines whether a bonus triggering event is generated for a first bonus game (106), second bonus game (112), or a third bonus game (118). The gaming device then determines whether at least a first predefined number of paylines are wagered (108), at least a second predefined number of paylines are wagered (114), or whether at least a third predefined number of paylines are wagered (120). If the gaming device determines that a first predefined number of paylines are wagered (108) then a first bonus game is initiated having a first average payout per credit bet (110). If the gaming device determines that a second predefined number of paylines are wagered (114) then a second bonus game is initiated having a second average payout per credit bet (116). If the gaming device determines that a third predefined number of paylines are wagered (120) then a third bonus game is initiated having a third average payout per credit bet (122).

    摘要： The present invention provides an architecture and method for a gaming-specific platform that features secure storage (354) and verification (366) of game code and other data, provides the ability to securely exchange data with a computerized wagering gaming system, and does so in a manner that is straightforward and easy to manage. Some embodiments of the invention provide the ability to identify game program code as certified or approved, such as by the Nevada Gaming Regulations Commission or other regulatory agency. The invention provides these and other functions by use of encryption (216), including digital signatures (220) and hash functions (210) as well as other encryption methods.
