Abstract: An electronic device comprising a master controller, numeric and alphanumeric displays, a numeric keyboard, control buttons, a pattern-input switch matrix, a card-input assembly and an optional audio module--all in one unit--automatically reads coded numbers on a card, accepts numbers as well as patterns whereupon it indicates by visual and optionally audible means when a win (i.e. "BINGO") occurs. The basic device can easily be adapted so it can be used to play other card games besides BINGO, (e.g. LOTTO).
