  • Patent number: 4902011
    Abstract: A game apparatus which utilizes a plurality of magnetized playing pieces is disclosed. The magnetized playing pieces are in the shape of two-sided circular discs, one side having a north polarity and other side a south polarity. The common polarities are identified by a surface color or by indicia printed thereon.The playing pieces are displayed on a flat, horizontal playing surface, preferably within a circular boundary on a rough-textured surface such as provided by canvas, leather or etched glass. The pole strengths of the magnetic playing pieces are sufficient to permit the balancing of a playing piece obliquely on its edge in proximity to but spaced from a flat-lying piece of like upward-facing polarity.
