This is a cool game called Cold Blocks which is really cool. It's an amazing, classical, and addictive puzzle game. You get 3 different shapes of blocks and you need to fill them into a pool that is 9X9. Once there is no extra space, it fails. Each time when you get a row, a line, or a 3x3 square, you will be able to destroy them. Your highest score is recorded, try to break it.
