How to solve pipe puzzles
The goal: every tile joins one network fed by the well, with no pipe ending in mid-air and no loops. Three ideas solve almost every garden.
Questions
How do you play the pipes puzzle?
Tap a tile to turn it a quarter turn. Turn the tiles until water from the well in the middle reaches every plant, with no pipe ending in mid-air and no loops.
Does every garden have one solution?
Yes. Every published garden was checked by a solver: it has exactly one solution, and you can reach it step by step by reasoning, without guessing.
What do the hints do?
A hint first shows where to look, then explains why that tile can only turn one way, and only then turns it for you. Use as much or as little help as you like.
Is there a new puzzle every day?
Yes. A new daily garden arrives every day at midnight UTC. Practice gardens in three sizes are always available too.
Is Puzzle Desk free? Do I need an account?
It is free and there is no account. Your progress is saved in this browser.
Can I play with a keyboard?
Yes. Use the arrow keys to move around the garden, Space or Enter to turn a tile, Shift with Space to turn it back, P to pin a tile and Ctrl+Z to undo.
