Intense puzzle game that really puts you under pressure, much like the pipes you're working with.

Good game, stimulates my brain tissues

There's also a Game Boy version. This game is addiction in a cartridge.

I probably shouldn't love this game as much as I do. The concept is simple, but it just triggers the right parts of your brain so that all you want to do is twist that next pipe into place. It's like they figured out how to digitize powerwashing videos into a game (before they actually just made a powerwashing game).
