  • Patent number: 5116062
    Abstract: A board game for two players includes a game board consisting of ten rows of eight squares each arranged like in an alternating pattern of playing and non-playing squares. Each player is provided with two sets of game pieces with each set consisting of twelve game pieces individually and consecutively numbered 1 through 12. On one set of game pieces the sides are marked with the mathematical symbols for addition and subtraction. On the other set of game pieces the mathematical functions of multiplication and division are represented. The game pieces of the opponent are similarly configured in two sets with the same numbering and the same mathematical functions. The only difference between the two sets of game places of each player are their color so as to distinguish the pieces of one player from those of the other. The game is played in a conventional manner much like the traditional game of Checkers with the players moving forward, jumping, removing the jumped piece and becoming a king.
