  • Patent number: 5326104
    Abstract: An automated casino gaming system includes a central game controller to which a number of automated writer stations are connected. In the keno playing embodiment disclosed, the automated writer stations each have a keypad with two colored LEDs mounted under each key. To play a game, patrons first insert a card into the automated writer station to identify their account maintained on the central game controller. The patron then enters a wager on the automated writer station. As the patron picks the desired numbers, LEDs of one color associated with the keys for the numbers will light. The patron presses a PLAY key to transmit an electronic "ticket" to the central game controller. When the period for entering wagers has ended, the central game controller requests a random draw from a separate, secure random number generator.
