Pipe Mania (also known as Pipe Dream is a tile-matching (sort of) puzzle game about flowing liquids developed by The Assembly Line in 1989. You must build a path made of pipe pieces to let a green liquid (sewer goo?) flow. It's simple, original and addicting, that's why Pipe Mania was cloned a number of times.
