Abstract: A system for playing bingo which includes a transmitter and at least one receiver. The transmitter includes a masterboard with associated ball-actuated switches which deliver signals in parallel format representing numbers in a bingo game. A parallel-to-series converter is provided to convert the signals into a series format. The receiver includes a series-to-parallel converter which effects a reconversion of the received signals into a parallel format and a flashboard which is coupled to outputs of the series-to-parallel converter and displays the numbers of a bingo game.
