Each level of this abstract puzzler challenges the player to set up a network of pipes to allow an unspecified substance known as 'flooz' to flow through as many of those as possible.

  • It Takes about 5 seconds to get the idea. It takes a lifetime to get good at it. Really good
  • It’s originally known as Pipe Mania but Pipe Dream is definitely the better name
  • Isn’t this the hacking game in Bioshock?!
  • Within BioShock, a variation of the game exists as a means of hacking vending machines, robots and cameras.[31] Alien Swarm, Saints Row IV and Warframe also use Pipe Dream-like minigames to represent hacking tasks.
  • Pipe Dream like hacking is a main mechanic of Half-Life: Alyx, with players solving puzzles in 3D space as a means of hacking doors and electronics in VR.
  • The game takes place on a grid where green slime, called "flooz," flows from a designated entry point. A dispenser holds five pipe sections, with the bottom piece placed when the player clicks an empty square. New pieces drop in from the top, and they must be used as-is, without rotation or flipping.
  • The goal is to create a continuous pipeline for the flooz, meeting a minimum length requirement. After a delay, the flooz starts flowing and stops if it reaches an open end or the playfield's edge. If the pipeline meets the required length, the player advances; otherwise, the game ends.
  • Before the flooz enters a pipe, players can swap it for the next dispenser piece, but this incurs a score penalty and a short delay.
  • Later levels introduce added complications, such as:
  • Higher minimum pipeline lengths and shorter delays before the flooz starts to flow.
  • Higher flow speeds.
  • Obstacles or pipe sections already on the field, which cannot be replaced.
  • An end piece into which the flooz must be routed. Failing to do so ends the game, even if the length requirement has been met.
  • Openings at opposite edges of the grid, allowing the flooz to wrap around from one to the other.
  • Reservoirs that take a few seconds to fill once the flooz enters them, giving the player extra time to place pipes.
  • One-way pipe sections that allow flow only in the indicated direction.
