An electronic game for positional games such as chess comprises a playing board and a plurality of playing pieces, each piece being movable between playing positions on the playing board in accordance with a predetermined pattern which is influenced by the locations of other playing pieces. Each playing piece is encoded in accordance with its identity, and each playing position automatically responds to the encoding when it is occupied by a playing piece. An electrical circuit associated with the playing position causes other positions to which the playing piece is capable of moving to be illuminated with an appropriate color. Each playing piece includes light sources which are illuminated when the playing piece is in jeopardy of being captured by an opposing playing piece or is covered by a friendly playing piece. The intensity of attack and the depth of cover may also be indicated. The playing pieces are automatically oriented in a predetermined manner when they are placed on a playing position in order to establish electrical contact between electrical terminals on the base of the playing piece and electrical terminals on the playing position.
