Me and my boys both enjoy this challenging game. Great skill builder too.

I really like this game and it's well worth its price. The interface is really unique, with nice use of the touch screen. I would like it even better if it would: 1. Remember the game you're currently playing if you need to leave the app 2. Remember your game settings 3. Allow you to view your game after it's complete 4. Ask if you're sure before resetting high scores

Puzzle itself is Amazing!!! Design and Interface is Super Cool and Amazing!!! In short this is worth spending $0.99 on this cool Math Puzzle Game.

Great game. I agree with most of the requested enhancements, especially a "show solution" option. I found one game that is unsolveable (have a screen shot if anyone doesn't believe me), so I would be interested for the game to show me the alleged solution. Love the quick mental stimulus.

I enjoy this game just to play for fun, yet it is a challenge. Thanks for the game.
