  • Patent number: 5441259
    Abstract: A double match jackpot with (2) separate identical operating mechanisms in the machine is the invention. The two (2) identical mechanisms operate independently with no set combinations of play. Each play is with random results. A winning play is not determined by the number of plays made previously. The matching of two (2) identical symbols on pairs of facing discs determines a win. Operating sections can be attached separately to other identical operating sections to increase the odds in any play of the machine. Odds can be increased also by addition of identical symbols to the edges of facing discs.

  • Patent number: 4010956
    Abstract: An automobile drag racing game comprising a playing board having two parallel lanes each of which is designed to accommodate a playing piece in the form of a miniature drag racing car, so as to conduct a drag race between the two cars under conditions simulating those of an actual race. The playing board is divided into four transverse zones corresponding with the portions of a drag race in first, second, third and fourth gears. Movement of the cars is controlled by dice, or in another embodiment by a number wheel actuated by a gear shift lever which can be shifted into first through fourth gears. The numbers thus randomly selected are utilized to determine the number of feet which the car may advance in any given gear by reference to a conversion chart with which each player is provided. Each conversion chart is calculated to produce racing performance characteristics of a well known type of car and driver.

The playing board is divided into four transverse zones corresponding with the portions of a drag race run in first, second, third and fourth gears. Movement of the cars is controlled by dice, or in another embodiment by a number wheel actuated by a gear shift lever which can be shifted into first through fourth gears. The numbers thus randomly selected are utilized to determine the number of feet which the car may advance in any given gear by reference to a conversion chart with which each player is provided.

  • Patent number: 3945644
    Abstract: A game toy comprising a base, having an upstanding cylindrical ring wall provided with a plurality of circumferentially spaced windows, telescopically receives the depending wall of a top member rotatably supported by a base axle. A plurality of symbols printed on the periphery of the top wall are successively visible through the base ring windows when the top member is rotated. The top member is provided with a plurality of upstanding radial ribs. A releasable brake including a flexible flap, supported by the base, frictionally engages the ribs of the top member when it is manually spun, in either direction about its vertical axis, to stop its rotation and expose, by chance, the symbols through the base windows.
