FAQ
How do you play the pipes puzzle?
Each tap turns a pipe 90 degrees clockwise. Once water from the top-left source reaches every pipe and there are no dead ends (open ends that don't connect to a neighbor), you win.
Where should I start?
Pipes on the edge can't point outward, so they have fewer possible directions. Lock in the corners and edges first, then work inward.
Is there only one solution?
Usually, but some layouts, such as ones that can form a 2×2 loop, have more than one. Any arrangement that gets water everywhere counts.
How is the leaderboard ranked?
By the time from opening the puzzle to finishing it, fastest first. You only need a nickname, and you can submit up to 30 times a day per size. The server checks the rotation of every tile.
