Electronic equipment is provided for playing a bingo-like game in a fashion closely simulative of the well known game of bingo played with paper cards. The three main functional components are: a) a central computer that is used both to determine which sets of faces are downloaded into players' game boards and to reconcile cash received by a salesperson with the number of downloaded games authorized to be played; b) players' game boards, each of which is adapted to receive enabling messages from a sales unit, to display enabled sets of playable indicia simulative of a bingo card and to modify that display responsive to a player's input; and c) the sales unit, which is adapted both to send an enabling message to a player's game board responsive to a manual input from a salesperson, and to record each such enabling transaction for later upload to the central computer. Another feature of the system is a switching arrangement for controlling a LCD display in a manner simulative of the use of a conventional ink dauber in marking a paper bingo card. This may be done by using a permanent magnet disposed on a simulative dauber that cooperates with a Hall-effect, or other, magnetic field sensor disposed behind an LCD display cell.
