Pipe Rotation Puzzle: how to play, rules & tips
Play the Pipe Rotation Puzzle free online: tap tiles to turn the pipes until every piece connects to the source in the center, with no leaks. There are ten levels and a free hint.
How to play the Pipe Rotation Puzzle
Every square on the board holds a piece of pipe: an end cap, a straight, a bend or a junction. Tap a tile to turn it a quarter-turn clockwise.
The source sits in the center of the board. Pipes light up as they connect back to it, so you can see your progress as you go.
The level is solved when every tile is connected into one network, every pipe end meets another pipe end, and nothing points at the edge of the board.
Levels and rules
| Difficulty | Levels | Board |
|---|---|---|
| Easy | 4 | 5×5 |
| Medium | 3 | 6×6 |
| Hard | 3 | 7×7 |
The ten levels are fixed, so a level is the same every time you play it. Each one was built from a finished network and then scrambled by turning the tiles, so it can always be solved.
The finished network never contains a closed loop, and it reaches every square on the board. Hint turns one tile into its correct position. Reset puts the level back to its start. There is no timer and no move limit.
Pipe Rotation Puzzle tips
- Start with the edges and corners. A pipe there cannot point off the board, which often leaves only one or two ways it can sit.
- A straight pipe on an edge must run along that edge, and a bend in a corner has only one legal position.
- End caps are dead ends. Two end caps next to each other should never point at each other, or that pair would be cut off from the rest.
- Because the network has no loops, if a turn would close a ring of pipes, that turn is wrong.
- Use the lit pipes as a guide. Work outward from the source and fix tiles where the light stops.
