As others mentioned... – Cubica Review

Fun game, very strategic and methodical and once you learn your "method," it will carry you through the entire game. It's an easy to pick up and put down game at any time. Unfortunately... I played it all the way until level 56, and now it has glitched and won't let me progress. And the higher levels take quite a while to finish so I've invested a bit of time into this. It's rather inconsequential, but still a bummer as I would have liked to get to level 100.
