Pipe Rotate: Water Puzzle

About this game

A board of water pipes has been scrambled. Tap a pipe to turn it a quarter turn, and keep turning until the water from the pump in the middle reaches every pipe on the board.

HOW IT WORKS
Water starts at the pump. Each tap rotates one pipe 90 degrees clockwise, so four taps bring it back where it started. You win when two things are true at once: the water has reached every pipe, and no pipe mouth is left pointing at nothing. An open end means a leak, so a board can be fully wet and still not finished.

Where to start: pipes along the border cannot point off the board, and a cap has a single opening that has to face its one neighbor. Those two facts usually unlock the rest.

ANY LAYOUT THAT CONNECTS EVERYTHING COUNTS
The game checks the connections, not a stored answer. If you route the water a different way than the puzzle was built, that is still a win. You are never told your solution is wrong because it is not the one on file.

EVERY PUZZLE CAN BE SOLVED
Boards are generated on your device from a structure that is guaranteed connectable, so you are never handed something impossible. There is an unlimited supply.

FOUR SIZES
5×5 to start, 7×7 and 9×9 as you get faster, and a 9×9 that wraps around the edges — a pipe leaving the right side comes back on the left.

TAKE AS LONG AS YOU LIKE
No timers. No move limits. No lives. A move counter and a par target are there if you want something to beat, and you can ignore both. A free hint will point out one pipe that is facing the wrong way.

DAILY PUZZLE
One board a day, the same one for everyone, with a streak if you keep coming back.

MADE TO BE COMFORTABLE
Dark mode, and a colorblind-friendly palette if the blue and grey are hard to tell apart. Everything is free — no in-app purchases.

PLAYS ANYWHERE
Puzzles are built on your phone, so it works on a plane, on the subway, or with no signal at all. No account, no sign-in.

A quiet puzzle you can pick up for two minutes or twenty.
