My eight year old son loves this game. It has quickly become one of his favorite and most used apps on our iPad. What's great is that this game actually helps kids develop thinking skills, instead of just playing mindless games or watching mindless shows like Sponge Bob. It has some similarities to Sudoku but with an added twist. Your child must fill in the rows with shapes but match them up with colors too. My son has really improved his critical thinking skills and his teacher in school asked what has gotten him thinking more. I told her about this app and she was pleasantly surprised. Oh, parents can play it too. It's not as easy as you think. A good, entertaining way to spend some time with your kid.
