Pipe Mania is a puzzle game developed in 1989 by The Assembly Line for the Amiga. It was ported to several other platforms by Lucasfilm Games, who gave it the name Pipe Dream and acted as general distributors for the US. In this game, the player must connect randomly appearing pieces of pipe on a grid to a given length within a limited time. The Windows version of the game was included in the MS Windows Entertainment Pack. In 1990, it was released as an arcade game by Japanese manufacturer Video System Co. Ltd., though with slightly altered gameplay, giving the player the task to connect a source and drain with the random pipe pieces. Long after its initial release, the Pipe Mania concept re-emerged as a minigame representing hacking or security system bypassing in larger video games.
Gameplay
Using a variety of pipe pieces presented randomly in a queue, the player must construct a path from the start piece for the onrushing sewer slime, or "flooz", which begins flowing after a time delay from the start of the round. Pieces may not be rotated; they must be placed as presented in the queue. The player can replace a previously laid piece by clicking on it, as long as the flooz has not yet reached it; however, doing so causes a short time delay before the next piece can be laid. The flooz is required to pass through a given number of pipe pieces in order for the player to continue to the next round. Some rounds also include an end piece, which must be the end of the pipeline the player has constructed, in addition to fulfilling the minimum pipe length requirement. Completing the sewer pipeline in the time allotted allows the player to advance to the next level, which means a shorter interval from the start of the round until the flooz starts flowing, as well as faster-flowing flooz. On higher levels, some special pipe pieces appear in the game, such as reservoirs, one-way sections, and bonus sections. Obstacles and wrap-around sections also appear on the game board on higher levels. If a player is able to finish the level using five cross-section pieces and filling them both ways, 5,000 bonus points are awarded. Bonus rounds present the player with a grid full of pipe pieces and one open space; the goal is to slide the pieces around and make the longest possible path for the flooz.
Reception
In Japan, Game Machine listed the arcade version of Pipe Mania on their November 1, 1990 issue as being the most-successful table arcade unit of the year. The game was reviewed in 1994 in Dragon #211 by Jay & Dee in the "Eye of the Monitor" column. Jay did not rate the game, but Dee gave the Macintosh version of the game 2½ out of 5 stars, and the Windows version 4½ stars. Macworld named the Macintosh version of Pipe Dream the Best Arcade Game of 1990, putting it into the Macintosh GameHall of Fame, and called it an "addictive strategy game".
Within BioShock, a variation of the game exists as a means of 'hacking' vending machines, robots and cameras. Alien Swarm, Saints Row IV and Warframe also use Pipe Dream-like minigames to represent hacking tasks. The North Korean game Railway Assemblage, sponsored by North Korean propaganda regime Uriminzokkiri and released on December 9, 2006, includes a simplified version of Pipe Mania. The game involves joining together sections of railway in order to build a fast railroad track from South Korea to North Korea, before the KTX-shaped train appears on the screen.
