  • Patent number: 7364431
    Abstract: A multiplication game consisting of a perforated game board in which the assemblage of perforations forms a rectangular matrix. In a horizontal row of numerals printed on the rim of the board the numerals increase evenly in value from one end to the other end, and below each numeral is disposed a column of perforations. A column of numerals is printed on the edge of the board such that the numerals increase evenly in value from one end to the other end. A set of chips is provided, the total number of which equals to the product of the largest value in the column multiplied by the largest value in the horizontal row, and each chip is insertable in a cut-out window of the board. Each chip has one numeric value inscribed on its upper face, such that for each multiplication of any number in the row with any number of the column there is found a matching numeral on a chip.
