A backgammon calculator has a keyboard laid out in the configuration of a backgammon board, with keys for entering men on the points and bar to set up a game position, and further keys in the home and outer boards between the points for amending the game position, for identifying the player which has the next turn or whose position is to be calculated, and for initiating a number of different calculations as to a player's position. The data entered and the results of the calculations are displayed on a digital read-out.
