Pipe Dream (a.k.a. Pipe Mania outside the US) is the pipe connecting puzzler designed by Akila Redmer and Stephan Butler. It was developed by Assembly Line in 1989 for the Amiga. It was later ported to several other platforms by Lucasfilm Games (who also changed the name into Pipe Dream).
There was one sequel called Pipe Dreams 3D, and it has made its way onto mobile. It has also influenced many similar games and specific minigames in other titles. For example, a hacking minigame based on Pipe Dream can be found in Bioshock.
The object of Pipe Dream is to line up pipe pieces to get the fluid to flow through a certain number of pipes to advance to the next level. There are seven different kinds of pipes that will appear in random order, so place them wisely. The pieces can’t be rotated and must be used as oriented. However, the parts can be switched out, but this will cost you points and keep you from being able to place anything else for a few seconds. Bonus points are awarded for accomplishments like looping the fluid through all game board sections. There are also a few bonus rounds to enjoy. If you’ve got a mind for puzzles, try your hand at this one.
