The board is a 10 x 10 grid of squares numbered in order from 1 to 100. These squares are of different colors, and each color has a different point value, e.g. red squares are worth 13 points, and the red squares include 13, 26, 39, etc. Each player has 10 square pieces of a different color which he places on the squares on the board and receives the number of points given for the color of that square. Whoever has the most points when all the pieces have been placed is the winner. Which squares players may place pieces on is determined by a roll of 3 dice; the numbers rolled may be put into an equation involving addition, subtraction, multiplication, and/or division. For example, if a player rolls a 2, 3, and 4, he may place a piece on the 9 square (2+3+4), the 24 square (2x3x4), the 10 square ((3x4)-2), etc. He may not place a piece on an already occupied square unless the occupying piece is one of his own piece.
