Customer Reviews


I cannot believe the creator of this game had the nerve to charge anything for this complete waste of time. Each game takes about a minute, and they're only about 12 of them. No challenge at all except to wonder how somebody can rip off people like this. Unless you are under 12 years old with the tiniest of fingers you can't help but hit more than one block at the same time, but it doesn't matter because even a six-year-old would find this very unchallenging. If this is the kind of garbage that the App Store allows to sell this is the last time I buy another App. Shame on the owner and shame on me for falling for it.

Love it!!!

This game keeps me sharp on my problem solving skills! I love it! If works great and I have never received any bugs! I love the auto fill option, it's amazing!
