Abstract: A mathematical board game including a game board bearing a rectangular grid defining a plurality of ranks and files. Additionally, the game board includes a scoring apparatus composed of two groups of labeled scoring bins, one group for each playing team, for the purpose of recording the score as the game is played. The game board also includes a sum/point tabulation table which provides a cross reference, relating sums with scoring points awarded for each sum. A plurality of scoring `stones` are provided for each player. Upon scoring, the scoring player places a single stone in his labeled scoring bin corresponding to the number of points scored. A plurality of tiles are also provided for each player, each tile being marked with a symbol representing one of the numbers in the range [1, 2, 3, . . . , N.times.M] for placing on the board, where N is the number of ranks and M is the number of files.
