About the Game

The game is played on a 8x8, or 10x10 board, or as a TV show. The game contains 400 coins/checkers with numbers from 1 to 100 on one side, and the sign Plus or Minus on the other side. The numbers fill the board, and players will have to make accurate guesses for the sum of a certain row or column, without knowing the sign of each number.

The total permutations for this game are incredible! On a 8x8 board = 5.94*10^173. For a 10x10 board = 2.58*10^241. The game is full of suspense because players have no way to check that many permutations.
