What do you get when you crossbreed Tetris and PipeDream? A double doze of enjoyment, challenge and action. PipeFun 2 is a new absorbing game that no PC game aficionado should overlook. The rules are very elementary - rotate various pieces of pipes to fit every other and form a "closed system" for the pipes to vanish. Sounds easy, but it's not. To aid you out, you will get a bomb sometimes to just blow it up. Available for free download now.
