Game Directions

This game needs at least six dice. This game can be played with more dice, but it may make the solutions too easy. Using fewer dice will result in impossible situations with no solution.

Before rolling the dice, select one die to be the answer die. For this example the red die will be the answer die.

Roll the dice. All five of the other dice must be used in the solution. The numbers may be used in any order, but each number must be used exactly once.

The numbers may be added, subtracted, multiplied, or divided. Parentheses, squares, square roots or any other mathmatical function may be used. Note: It is seldom necessary to do more than add, subtract, multiply, or divide to find a solution. Older children who have had algrbra may enjoy using more advanced functions to find a more difficult solution.
