Brain Thaw is a math based puzzle game for the iPhone and iPod Touch. This game may seem simple at first, but unless you're really quick with your math, you'll be surprised how challenging it can get.
Each level is going to provide you with thirty squares for you to move around on. Tapping on a square will bring your penguin over to it. Double tapping will eat that specific square. While you're moving around, you'll need to avoid the yeti's that will eat you if you cross their path.
