Nice math learning puzzle game. A good pass-time. I guess it's good for kids to learn addition, subtraction and multiplication and it's definitely a good challenge for an adult which wants 3 starts on all levels. Puzzle difficulty varies, not all puzzles in the last room seemed hard to me (to get 3 stars). Graphics are nice. Bought this app after doing and online course about how the brain learns. It would be nice to find some games for grownups to learn more complex stuff than basic math operations.
The game play is slow and the math is simplistic This is likely only useful for very young math students. My son didn't enjoy it
