Abstract: Dynamic tournament gaming method and system, including the provision of a plurality of gaming terminals selectively interlinkable together with a host terminal so that current players of the terminals desiring to participate in group tournament play can be notified of the opportunity and provided with the choice to play or not. If a current player chooses to play, he so signifies, enters his entry fee into the terminal, and awaits start of the event. Upon start of the tournament by the host terminal, the player will play the tournament game over and over as fast as possible to accumulate as many points as possible during a particular pre-announced tournament period. The host terminal will continuously monitor the terminals of all play participants, dynamically record play status, and control termination of the game period. It will also conduct an accounting of the results, issue win results notification, and perhaps provide remote pay-out of game winnings.

Abstract: A method and apparatus for generating random numbers for use in electronic applications is disclosed. A given sequence of random binary numbers of a certain length can be decoded into several random numbers for a specific application. The upper range values of the random numbers to be decoded determine the number of bits required for the generation of the these random numbers. In the decoding process, the given random binary number divides a range value to generate a remainder and a quotient. The quotient becomes the new random binary number for the generation of other random numbers while the remainder is the generated random number. The process then repeats to generate other random numbers. At the end of the generation process, the last quotient determines the validity of the generated random numbers.

Abstract: The electronic casino gaming system consists of several system components, including a microprocessor (12), a main memory unit (13) that is typically a random access memory, and a system boot ROM (14). Also included in the electronic casino gaming system are a non-volatile RAM (17), a mass storage unit (18), a disk subsystem (19), and a PCI bus (20). The disk subsystem (19) preferably supports SCSI-2 with options of fast and wide. A video subsystem (22) is also included in the electronic casino gaming system and is coupled to the PCI bus (20) to provide full color still images and MPEG movies.

Abstract: Method and apparatus for providing authenticated, secure, on-line communication between remote locations including a user terminal adapted to enable a player in one location to remotely communicate via a communications medium such as the Internet with a gaming host in another location. Location of the remote user terminal, the host server and universal time are determined using means for accessing signals generated by geostationary navigational transmitters, such as in the global positioning satellite (GPS) system. Player authentication (identity verification) is determined by use of a personal identification number (PIN) and an electronic signature verification service. Security of communication is accomplished through use of a public-key/private-key encryption system.

Abstract: An operating system having a multitude of subsystems is provided where each subsystem performs a distinct function and may register with other subsystems to receive notification (or callbacks) upon the ocurrence of certain events. Moreover, the subsystems are programmed in such a manner where in the event of a fault (or exception) they can be instructed to cease the calling of other subsystems, thereby allowing each of the subsystems to complete its distinctive task without commencing further additional activities. When all of the activities have ceased, the state of the system as indicated by the parameters at the various registers and addresses are saved. At this time, the system can initiate a service call for an attendant through one of the provided mechanisms or routine calls.

Abstract: A method for ordering all of the possible hands into a particular sequence is presented. Due to the particular manner in which the hands are ordered and sequenced, any one of the hands can be accessed fairly quickly by the methods provided herein which simplifies complex calculations to table look-up operations. Given a particular hand (the first five cards given to the player in a five-card draw poker), all of the possible hands arising from the particular hand (as a result of the number of cards kept by the player) is iterated and the types of all possible resulting hands tabulated. The combination of hands resulting from the number of cards kept is considered in the iteration. After the iteration is completed, the results obtained is a tabulation of each combination of hands obtained.

Abstract: A two-dimensional random number generator for use in electronic applications is constructed of a shift-register random number generator using the coefficients of a primitive polynomial of degree k to generate sequences of random binary numbers, and a second random number generator to provide an index to an array of storage locations for storing and retrieving the sequences of random binary numbers generated by the shift-register random number generator.

Abstract: The present invention relates to a signaling system which provides as part of the signal an indication as to the approximate elapsed time since the activation of the signal. Furthermore, the type of service required can be indicated by a particular flashing scheme or color code. The system has both software and hardware components and can be easily integrated into individual game machines. In the preferred embodiment, the hardware component includes a software controllable switching means for controlling a plurality of lights. In order to identify the type of service needed, lights may be color-coded or different flashing patterns may be used. In the software component, a preferred algorithm which defines and varies the flash rate over time is implemented. The flash rate is defined as being in the on-state for a first specified duration and in the off-state for a second specified duration.

Abstract: A dynamic rate control method and apparatus for electronically played games and gaming devices and including an adaptable game play controller having a nominal play speed characteristic that is adjustable both up and down, together with means for sensing player input rate and for making stepped adjustments to the controller so as to cause the game play speed to follow the frequency of input by the player. The controller and sensing means can be implemented in either hardware or software, or a combination of hardware and software.

Abstract: An electronic casino gaming system includes an unalterable ROM for storing a casino game authentication program, including a message digest algorithm program, a decryption program and a decryption key. A casino game data set containing casino game rules and image data is stored in a mass storage device, such as a local disk memory or a remote network file server, along with the signature of the casino game data set. The signature is an encrypted version of the message digest of the casino game data set, prepared using a hash function. Prior to permitting game play by a player, the casino game data set is transferred from the mass storage device to main memory and during this process the message digest is computed from the image data using a hash function stored in the ROM. The encrypted version of the message digest transferred from the mass storage device is decrypted using the decryption program and decryption key stored in the unalterable ROM.
