Crack Attack

Crack Attack is a puzzle game with the same idea as Tetris Attack. By moving colored blocks from side to side, you line up 3 or more in a row to pop the blocks. This game has internet multiplayer so you can play it with your buddies as a fun time waster. It is available in Linux, Mac, and Windows. In ubuntu you can install it with "sudo apt-get install crack-attack" as it is already in the repo.
