Abstract

An automatic gaming system for games of chance, such as BINGO or the like, is disclosed comprising a system base station, a plurality of electronic gaming boards, and a plurality of validation units. The electronic gaming boards are initialized by the system base station with a complex gaming schedule developed by the system operator. The system base station includes an interactive program to create a complex gaming schedule having completely arbitrary win patterns, multiple levels of payouts, and multiple place win combinations. The system base station further loads each gaming card with data representing a variable time interval which causes all of the boards to enter the play mode at the same time. The validation units are initialized by the system base station with a validation code which is used when checking a win claim of an electronic card. The validation units store audit information gained during the validation of win claims and upload that stored information to the system base station at the end of a gaming session. The system base station further includes a program to command the electronic gaming boards and validation units to turn off or on.
