Not a drop spilled.
Pipe Connect
Turn the pipes to join every pump to its tanks without mixing colours or spilling a drop — 50 pipe puzzle levels.
About the Game
Pipe Connect is an original pipe-turning puzzle with 50 handcrafted levels. Each level is a boiler-room floor tiled with steel pipes: straights, corners, T-pieces and dead ends, all scrambled. Tap a pipe to turn it a quarter turn and watch the coloured liquid run from the pumps through every joint you line up. Fill every tank with its own colour to finish — but liquid that reaches an open pipe end spills, and two colours must never meet. Later levels bring several colours at once, crossing pipes that let two colours pass through each other, valves you open or shut to hold liquid back, bolted pipes that can't be turned, tap limits and, in the final chapter, a pressure timer counting down while you work. Every level has been solved by a computer search, so the par shown is the true fewest taps.
How to Play
Each pump pushes coloured liquid out of its nozzle. Tap any pipe to turn it a quarter turn clockwise, and line up the openings so the liquid runs from the pump to every tank of the same colour. The liquid shows you how far it gets as you play. A level is complete when every tank is full, no two colours meet, and nothing spills — liquid that reaches an open pipe end, a rock or the edge of the board spills, so every wet pipe has to be fully connected. Spare pipes that stay dry don't matter. T-pieces split the flow to feed more than one tank. A cross lets two different colours pass straight through each other. Tap a valve wheel to open or close it: a closed valve (red) holds the liquid back without spilling. Pipes with gold bolts can't be turned. Some levels limit your taps, and the last chapter adds a pressure timer: connect every tank before it runs out. Finish in the par number of taps for three stars.

Gameplay Tips
- Start at a tank's nozzle — the last pipe must point straight at it.
- Pipes in corners and along the edge can only face a few useful ways.
- Follow a spill back: the drip shows exactly which pipe is facing the wrong way.
- A straight pipe only ever needs one tap; a corner may need three.
- Shut valves on branches you don't need instead of rebuilding the network.
FAQ
What is Pipe Connect?
Pipe Connect is a free pipe-turning puzzle on ZOQSY. You tap pipes to rotate them and connect each coloured pump to its tanks without spilling or mixing colours.
How many levels are there?
50 handcrafted levels in five chapters, from a single bend to huge four-colour boiler rooms against the clock.
Why does my level not finish when the tanks are full?
Somewhere liquid is still spilling from an open pipe end, or two colours are touching. Look for the red ring that marks a spill and turn that pipe.
What do crosses and valves do?
A cross carries two separate flows straight through each other, so two colours can cross without mixing. A valve lets liquid through while open; closed (red), it holds the liquid back without spilling.
How do I get three stars?
Finish in the par number of taps — the fewest possible, found by a computer search. A few extra taps still earn two stars.
Can I play on my phone?
Yes — tap pipes with your finger. The board scales to fit any screen from a small phone to a desktop monitor.
Is Pipe Connect free?
Yes — free in your browser with no download or account. Stars and progress are saved locally in your browser.
