Wagering system with improved communication between host computers and remote terminals
First Claim
1. The method of operating a computerized lottery system, wherein the necessity for spontaneously transmitting each individual wager from a remote terminal to a host computer is eliminated, and wherein the total amount of data transmitted therebetween is substantially reduced, thereby reducing the consequent cost of transmission and enhancing the number and types of economically viable transmission alternatives, comprising the steps of:
- providing a host computer and a remote terminal;
generating a seed number at said host computer specific to a pool and said terminal;
transmitting said seed number to said terminal;
producing pseudo-random wager numbers sequentially for sequential plays within said pool at said terminal from said seed number;
conveying from said terminal to said host a total number of said sequential plays and a means for identifying said terminal uniquely; and
reconstructing pseudo-random wager numbers and serial numbers associated with each of said plays at said host from said total number of sequential plays and said identifying means.

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. The reduced data exchange makes available novel methods of data transfer, such as satellite packet transmission and cellular service.

16. A method of securely and compactly communicating wagering information regarding plays of a game between remote computers comprising the steps of:
-
establishing one of said remote computers as a host terminal, and establishing at least one of said remote computers as an agent terminal; delivering to said remote computers a pseudo-random number generating algorithm; generating a seed number and delivering said seed number to said remote computers; using said algorithm and said seed number to produce pseudo-random wager numbers; assigning at said agent terminal said wager numbers and sequential serial numbers to sequential plays made at said agent terminal, and creating a wager receipt for each of said plays therefrom; closing said game; conveying a total number of said sequential plays from said agent terminal to said host terminal; reconstructing said wager numbers and said serial numbers at said host terminal from said algorithm, said seed number and said total number of said plays; determining winning wagers; ascertaining a liability of said remote computers based upon said winning wagers and said wager numbers at said host terminal; and communicating winning selections and liability data to said remote computers. - View Dependent Claims (17, 18, 19)

20. A wagering system for a game which assigns wagering selections to players at an agent terminal and communicates said wagering selections to a physically remote host terminal, both said host terminal and said agent terminal capable of communications therebetween and also capable of performing mathematical computations and storing the results thereof, wherein the improvement comprises the further combination of a seed number and a pseudo-random number generating algorithm each stored at both of said host terminal and said agent terminal and each used at said agent terminal to generate said wagering selections, and a counter value which directly or through computation represents the total number of said wagering selections assigned at said agent terminal for said game, whereby said agent terminal may communicate said counter value to said host terminal and said host terminal can then reconstruct each of said wagering selections using said pseudo-random number generator, said seed and said counter value, thereby substantially reducing the amount of data communicated between said agent terminal and said host terminal.
