Roll the dice. Then decide whether to add, subtract, multiply or divide the numbers to get a single number between one and ten. Decision made, flip the levered key piece with that number. It's a strategic decision, because you need to flip all ten keys to win, and some numbers are harder to get. The first player to flip all ten pegs wins. It's a fun way to practice basic math facts, but the game is more than an educational tool. It is a fun, well-designed game that even older kids long past mastering basic math skills enjoy playing.
