Electronic completing the square game

Abstract

A pocket-sized electronic board game is disclosed. The apparatus for playing the game comprises a casing which serves also as the playing surface, through which project a plurality of push-buttons for actuating the keys in selected positions. A membrane-type key board may alternatively be used. The push-buttons and keys are arranged in a plurality of rows and columns with elongate light sources extending parallel to the rows of columns and between adjacent pairs of row-wise or column-wise keys. The electronic circuit within the casing acts to detect depression of two adjacent keys in any row or column and operates when such detection is made to cause the light source between the two actuated keys to illuminate and remain illuminated until the end of the game so that by depressing pairs of keys in turn players can "claim" sides of the squares constituted by the light sources. An embodiment including a microprocessor with a programme for providing moves representing those made by an opponent is also disclosed so that the apparatus can be used by one player.
