Abstract

Electronic game apparatus comprising a board displaying discrete playing areas and a number of playing pieces. Transmit and receive coils are provided beneath the surface of the board, preferably at right angles to each other, and each playing piece is provided in its base with an element. Means are provided for supplying a high-frequency current to each transmit coil in turn and for detecting the voltage induced in the receive coils for each discrete playing area. The presence of a playing piece on the playing area being tested, will affect the voltage induced in the receive coils and hence the presence, absence or type if desired, of a playing piece may be determined. The element preferably consists of any suitable metal or ferromagnetic material. Playing pieces of different types may be provided with elements of different materials.
