Abstract: A lighted display board or sign has a viewing face subdivided into 25 squares arranged five by five simulating a Bingo playing card and having a separate light positioned behind each square. An unusual circuit and switching arrangement makes it possible by merely closing a single switch to cause the lights on the board to indicate to the players what particular design, such as an "X", cross, square, etc., must be attained to obtain a "Bingo" or winner for the particular game then in progress. An on and off flashing light spelling out the words Bingo forms a part of the basic circuit.
