by Nebulark Studio · Puzzle · v1.1.0
Turn copper pipe tiles until water flows from the valve to every sprouting plant, with no open ends. A fresh five-board Daily Ladder every day.
How to play
- Pick Daily Ladder (ranked) or an Endless size and press Play.
- Tap or click a tile to turn it 90° clockwise. Right-click or long-press turns it anticlockwise.
- Water flows from the brass valve through every pair of pipe openings that face each other.
- Join every tile into one network, with no open ends, so that water reaches every plant.
- Stars: solve within par moves for three stars, par + 50% for two. A hint caps the board at two.
- Undo takes back a turn. Pin mode pins tiles you are sure of so they cannot turn.
- Hint turns one wrong tile into place and locks it (+15 s).
- Daily Ladder: solve all 5 boards as fast as you can. Lower time is better. Your run is saved, so you can Continue later.

About Pipe Link
Pipe Link is a tactile rotation puzzle on a blueprint-blue board. Every tile holds a polished copper pipe (an end cap, straight, elbow, tee or cross), and all of them start out turned the wrong way. Tap a tile to give it a quarter turn and watch glowing teal water race out from the brass valve through every joined pipe. The board is solved when every tile is part of one network, with no open ends and no loops, and every little plant at the end of a pipe has sprouted. Every board is generated fresh from a random spanning tree, so any arrangement that makes a valid network counts. Race the Daily Ladder, five boards from 5×5 up to 9×9, for the fastest total time (each hint costs 15 seconds), or relax in Endless on the size you like, including an 11×11 board whose edges wrap around. A high-contrast mode is built in.
