1. An electronic game apparatus comprising:

  • a playing board having a playing surface and playing areas;

    a first set of generally parallel transmission lines located beneath the playing surface of the playing board and arranged in a first direction;

    a second set of generally parallel transmission lines located beneath the playing surface of the playing board, said second set of generally parallel transmission lines being arranged in a second direction different from the first direction of said first set of generally parallel transmission lines, said first and second sets of transmission lines forming intersecting points which are electrically isolated from one another, each said intersecting point being positioned proximate a playing area of said playing surface;

    a source of electromagnetic energy having a plurality of predetermined different frequencies within a predetermined frequency range;

    a plurality of game pieces each game piece containing a resonant circuit having a predetermined resonant frequency correspond a frequency within said predetermined frequency range;

    selector means for sequentially supplying electromagnetic energy signals at selected frequencies within said predetermined frequency range to said first set of transmission lines;

    detection means connected with said second set of transmission lines for detecting electromagnetic energy at a frequency within said predetermined frequency range on one of said transmission lines of said second set, whereby the presence of a game piece upon a playing area results in the generation of electromagnetic energy within a transmission line of said second set upon receipt by the resonant circuit within said game piece of electromagnetic energy from one of said transmission lines of said first set at a frequency corresponding to the resonant frequency of the resonant circuit within said game piece, said detection means detecting said electromagnetic energy within said transmission line of said second set to identify the playing area in which said game piece is located.
