ISO

Yea! Glad to see the update for iOS 11 BUT my scores are now all screwed up so what you gotta do is delete the game and reinstall. You lose your scores but they're beyond repair anyway.

9 years later I’m here with 6.0, I made sure to test score migration carefully so we don’t have any repeat mistakes! Thanks for your support.

A favorite casual game!

One of the first games I ever downloaded to my very first iPhone. Simple and relaxing. This one has been ported to each new phone and I keep coming back to it. Great for a few quick moments of stress relief.

Simple, but the best

This is the game I always come back to. It's in my home row and the one I turn to whenever I'm bored. Stellar, simple game mechanic that gets challenging fast.
