This appears to be an easy game, but it is not. When too many blocks freeze, you are challenged to recover else you have to restart. Fortunately, you don't have to start from the beginning.

How to play:
Slide the blocks to make them fall into empty spaces. Fill a row to eliminate that row. Blocks start freezing from below and can no longer be moved. Remove frozen blocks by filling the rows. Blocks above the cold zone will not freeze, but the cold zone gets bigger as you level up. Watch out, a winter storm is coming!
