Klocki

I spent a good deal of time over the weekend playing Klocki, a minimalistic puzzle game. There are no instructions on how to solve the puzzles, just a game board and some pleasant ambient music. You touch and tap around to discover how to move the pieces and each level gets a little more complex over time. So far it hasn't reached a level of maddening frustration, it's just enjoyable. Oh, and the Level Clear sound is awesomely satisfying.

It's on Android, iOS and even the web, so you've no excuse not to play.
