In this game the winner is the first to complete a row of three, either horizontally, vertically or diagonally.

Roll the dice, place each dice in one of the squares and decide whether you want to add or subtract to produce a total shown on the board. Your total will then be covered with a counter.

You cannot cover a number which has already been covered.
If you are unable to find a total which has not been covered you must Pass.

You can use the interactive version below or print this board to play away from the computer.
