Pipe Connect
In Pipe Connect you rotate pipe sections to carry water from the inlet to the outlet. Every board is solvable. Free, no install, no sign-up.
In Pipe Connect, each square holds a section of pipe. Tap one to rotate it a quarter turn and join the inlet to the outlet. Every board can be solved.

How to play Pipe Connect
Two conditions, both required
First, every opening of every pipe section must line up with an opening on the neighbouring section — no half-open stubs sticking out. Second, water must actually reach the outlet from the inlet. The first condition alone is not enough: a board can be perfectly joined up but split into two separate runs, and water still would not get through.
Dangling openings are marked in red
Any opening that faces a solid block or a section with no matching opening gets a red dot. Those dots clear one by one as you line things up, so you can see progress without guessing.
Water is shown as you go
Sections that are actually carrying water from the inlet are drawn in green with the rest in grey. That distinction is the whole feedback loop.
Every board is solvable
The board is built by first laying down a complete route from inlet to outlet, then rotating each section a random number of quarter turns. Since four turns return a section to where it started, the original arrangement is always reachable again — solvability comes from how the board is made.
Tap to rotate a quarter turn
Each section has four possible orientations. There is no way to rotate the wrong way: four taps bring you back to where you started, so nothing can be made permanently wrong.
Blocks are not pipes
The dark squares are solid ground that no pipe passes through. The route winds around them, which is why it is not simply a straight line across.
Pipe Connect Tips and Strategy
No red dots is not finished
Every opening can be lined up and the water still fail to arrive, because the joined pipework can be split into two separate runs. Red dots only report loose ends, so treat them as necessary rather than sufficient. Follow the green from the inlet: if it stops short of the outlet, you closed off the wrong part of the route.
Build backwards from the outlet
The outlet's own orientation fixes where the route must arrive from, so start there and work towards the inlet rather than pushing water forward from one end. That anchors every decision to something already fixed. It also stops you building a long green run that dead-ends against a section you have not reached yet.
Clear loose ends near the inlet
A red dot next to the inlet is the cheapest progress available, because turning that section usually extends the green immediately. Work outward from the inlet section by section, clearing every red dot as you pass it. The blocked squares are where routes bend, so expect the loose ends to cluster around them rather than spreading evenly.
Pipe Connect — Frequently Asked Questions
All the openings line up but it says I am not finished. Why?
Because the water cannot reach the outlet. The route may be joined into two separate runs. The red dots tell you about loose ends; the green sections tell you where the water actually got to.
Can I get a board into an unsolvable state?
No. Rotations cycle, so four taps on a section always bring it back to where it started. Nothing you do can make a board impossible.
What are the dark squares?
Solid ground. No pipe runs through them, so the route has to go around.
Does it need installing or an account?
No. It runs in the browser on a phone, tablet or computer and works offline after the first visit.
