ABSTRACT:
A game of backgammon played electronically in which movement of men by the players is limited to switch controls exclusively. A memory stores signals representing the number of men of each player at each of the game positions and these signals are used to energize light emitting diodes on a console to display the positions of the men. The memory is updated each time a player moves a man to store signals representing the changed positions. Control circuitry in the console, in accordance with the rules of the game, (1) moves a man of one player from an initial game position to a final game position, (2) moves a man of the other player on the final position to the 0 position of this other player if this other player has only one man on the final position, and (3) prevents the one player from moving a man to the final position if the other player has at least two men on the final position. The console includes additional light emitting diodes which are controlled by the circuitry to be sequentially energized to display movement of a man from the initial position to the final position. Electronic dice are activated by push buttons and display on the console the number of positions a player may move his men. The game also includes a points doubling logic circuit which includes a numeric display on the console as the multiplier of the number of points being played for and push buttons enabling each player to double the number displayed each time a button is depressed, thereby doubling the points.
