Math Zombie is an addition app. The goal is simple: in 10 seconds, players must combine numbers to equal the number in the big yellow box. Players must clear the board to move to the next level. Points increase when more numbers are combined. In order to double your points, players must use the same color numbers. It is a quick thinking addition game, and the zombie theme is fun for kids.
Pros: FREE, easy to catch on right away, has several difficulty levels, fun "Zombie" theme.
Cons: Sometimes its not possible to pick numbers that are of the same color, so you receive less points for picking mismatched colors. Only in addition.
