Game Where You Connect Pipes: How to Play Pipe Spin, Edges First

If you're looking for a game where you connect pipes by turning tiles, try Pipe Spin first. Every tile holds a piece of pipe, all of them start twisted, and you rotate them until one network runs from the dark tile in the middle to every corner of the board. No download, no account, and each board has exactly one answer.

The rules take ten seconds. Getting fast at it takes a few habits, so here they are, plus a second pipe game for when squares start feeling easy.

How to play a game where you connect pipes

There are four kinds of tile in Pipe Spin: a straight, a bend, a T-junction and a dead end (the little square cap). Tap a tile and it turns. The buttons under the board decide whether it turns left or right.

A tile lights up once it's joined to the source. The counter under the board tells you how many are lit, something like "Active: 7/25" on the 5×5. You win when every tile is lit and no pipe points at a wall or at a blank side of its neighbour.

That second part matters. A board can look almost done with one pipe still poking into nothing. Check the edges before you decide you're stuck.

Start from the border, not the middle

The source sits in the middle, so it's tempting to start there. Don't. The middle tiles have the most freedom. The border tiles have the least, because on a normal board nothing is allowed to point outside.

A few things fall out of that right away:

• A straight can't sit in a corner at all, and on an edge it has to run along the wall.
• A bend in a corner has exactly one legal position.
• A T-junction on an edge has one position too: flat side against the wall.
• A dead end in a corner still has two options, so leave those for later.

Fix the forced ones, then look at their neighbours. A pipe pointing into a tile means that tile must have an opening on that side. A blank side means it mustn't. Work inward like that and the middle usually solves itself.

Use Lock, and keep dead ends apart

Two dead ends side by side can't face each other. If they did, they'd form a tiny two-tile network cut off from the source, and the board would never fully light up.

Once you're sure about a tile, switch to Lock and tap it. I skipped this on my first 9×9 and turned a finished corner by accident while reaching for the tile next to it. On bigger boards it's not optional.

Undo and Redo are there if you go down a wrong path. Solve will show you the answer, but a board finished that way doesn't count as a win.

Wrapping boards: no edges to lean on

Open Type and you'll see the sizes (5×5 up to 13×11), each with a wrapping version. On those, a pipe that leaves the right side comes back on the left, and top joins bottom.

That kills the border trick completely. What I do instead is look for tiles boxed in by neighbours I already know. A straight between two known openings, or a T-junction with one known blank side, usually has only one way to go. Start the wrapping boards on 5×5. They're a different puzzle.

A second pipe puzzle game online free: Honeycomb Pipes

When square tiles feel solved, try Honeycomb Pipes. Same idea, but the default grid is hexagons, so each tile has six sides and more ways to turn. The pipe ends shaped like little bulbs are the dead ends.

Two things make it friendlier than it sounds. Tiles that are already joined share a colour, so you can see separate chunks of network. And if you close a loop, which isn't allowed, those tiles get highlighted. You can also draw along an edge to mark it as a wall, or across it to mark a connection, before you know how the tile turns.

Grid can also be square or octagon, size goes from 4×4 to 10×10, and there's a Wrap edges box. New puzzle generates a fresh one in your browser every time.

Which one to open first

New to pipe puzzles? Open Pipe Spin on 5×5, solve two boards from the edges in, then move to 7×7. Already comfortable? Go straight to Honeycomb Pipes on hexagons and see how long the border trick keeps working when every tile has six sides.
