This is the original 24 Game, which features single digit numbers and all four operations.

For years, the 24 Game has been the primary math game, even inspiring school and regional competitions. This is the original 24 Game, which features single digit numbers and all four operations. Kids race to add, subtract, multiply and divide the numbers on each card to reach 24. The answer is printed on the back of the card. Each set contains three levels of difficulty, so kids can keep playing once they master the basic facts. A child can also play alone for additional practice.
