The object of the game is to use pipe segments to connect a source to a destination. Pieces of pipe appear in straight, angle, or forking units. In the game, available pipe pieces are limited and scroll across the bottom of a screen on a conveyor belt. The player must select, rotate, and position pieces rapidly - pieces that scroll off the screen are lost. Selection and placement are performed with the mouse; rotations are performed by the keyboard. Additionally, the entire pipe circuit must be completed in a limited amount of time. Incomplete circuits cause the game to be lost.
