  • Patent number: 5316307
    Abstract: A three-dimensional strategy game is formed of four circular discs supported in vertically spaced apart relationship by peripherally spaced vertical posts. Each disc is provided with four concentric bands, and a plurality of station detents are located in each band on radial lines disposed 90.degree. apart. The detents are configured to seat game piece balls, and the posts are formed of hollow tubes configured to receive the balls for storage. A side opening at the bottom of each tube allows removal of the bottommost ball for play. The method of play is to place game piece balls in detents on one or more of the four discs to form a sequence of straight lines, circles or spirals, with the player producing or discovering a sequence being the winner of the game.
