  • Patent number: 4884817
    Abstract: A three dimensional game played by two players each having five identical playing pieces. The game is played on three similar boards or grids lying in three vertically spaced parallel planes. Each board contains thirteen spaces, nine of which form a central square with one of the four remaining spaces lying adjacent to the center of each of the four sides of the central square. To begin the game, the first player places one of his five pieces in the four outermost spaces and in the central space of the uppermost gameboard called the Alpha grid while the opposing player places his five pieces in the corresponding spaces of the lowermost gameboard called the Omega grid. The middle board is called the neutral grid. The central space of the Alpha and the Omega grids is that player's base and the object of the game is to capture the opponent's base by landing a piece on it or by first capturing all of the opponent's pieces.
