The gaming board when used for a BINGO game receives a schedule of a gaming session permitting a plurality of independent games, each with a number of win levels and payout places. A load mode is used to randomly input numbers for selectable BINGO cards which are then played during the independent games in a play mode. A set time for loading the BINGO cards into the gaming board is maintained by a counter which, when expired, automatically loads random numbers into those cards which have not been filled. A three tier power conservation and security operation is used to control the power supplies of the gaming board. Initially, the gaming board can only be powered on by connection to a system base station and turns itself off upon command from the system base station. During operation, an elapse of a predetermined interval without a key activation will power down the display and an elapse of a longer interval without a key actuation will power down the gaming board requiring reconnection to the base station.
