  • Patent number: 6475086
    Abstract: The necessity for spontaneously transmitting each individual wager from a remote terminal or terminals to a host computer in a computerized lottery system is completely eliminated. As a result, the total amount of data transmitted between the remote terminals and the host computer is substantially reduced. This reduces the consequent cost of transmission and enhances the number of economically viable transmission alternatives. A total number of sequential plays is conveyed from the remote terminal or terminals to the host computer. Pseudo-random wager numbers and serial numbers associated with each of the plays is reconstructed at the host computer from the total number of sequential plays. The reduced data exchange facilitates novel methods of data transfer, such as satellite packet transmission and cellular service.

  • Publication number: 20010051539
    Abstract: A computer selected “quick pick” wagering system uses keys in the form of random numbers to serve as seed numbers in a pseudo-random number generating algorithm. A sales agent's terminal uses the algorithm and seed to produce random number combinations for each play from a pool, assigning the number combinations sequentially and printing them, together with a sequential serial number, onto lottery tickets. By storing the algorithm and seed at both the host computer and remote agent terminal, the remote terminal can transmit all pertinent wagering information by only transmitting the actual count of plays sold, thereby reducing the amount of data exchanged by several orders of magnitude. The host computer can then reconstruct the wagers and compare them to winning number combinations. Liability information for each terminal is transmitted back to the agent together with new seed numbers, so the agent terminal may begin selling plays for a new pool while also verifying accurate data exchange.
