  • Patent number: 4200289
    Abstract: A planar nonmagnetic sheet is mounted in an open topped container with the top of such sheet spaced from the bottom of the container and edge portions of the sheet spaced from the inner sides of the container. The top of such sheet forms a playing surface for a playing piece or wobbler having a low center of gravity and a convexly curved bottom. Lower board magnets are located beneath the playing surface sheet at the four corners of a square. An upper board magnet is positioned above the playing surface sheet at the center of such square. Another magnet is carried by the wobbler. All of the magnets, including the lower board magnets, the upper board magnet and the wobbler magnet, are short cylindrical bar magnets oriented such that the same pole of each is generally adjacent to the playing surface, and the other pole of each is farther from the playing surface, so that the board magnets provide a magnetic field repelling the wobbler.
