An electronic alpha-numeric digit displaying device, together with a control unit and electronic circuitry appropriate to the encoding, sending, receiving, decoding, and displaying of data as used in various games, such as Bingo, Keno, or the like, in which a plurality of players may participate. In the exemplary game of Bingo, for instance, light-weight plastic balls, each marked with a letter and a number, are randomly selected and deposited into apertures in a console, by which action they are automatically identified through the breaking of one row and one column infra-red light beam of a coordinate grid of such beams. Through electronic encoding, transmitting/receiving, and decoding, the aforesaid letter-number combination is substantially instantaneously displayed in two places on a display board. One of these locations is on letter-labeled rows by the sequential order of the selected letter-number; the other location is on a separate row where appearance is determined entirely by the sequence in which the letter-number combination is selected. The numbers are continuously selected and progressively displayed until a round of play has been completed in accordance with various rules of the game being played. When this occurs, the display board is cleared and all of the balls are reloaded to begin the next round of play. The console contains manually operated controls which affect the game data stored in memory and thus the display board, also.
