How to play

  1. Click any pipe tile to rotate it 90 degrees clockwise.
  2. Connect the blue source (top-left) to the green sink (bottom-right) with an unbroken pipe path.
  3. Tiles currently fed by the source glow cyan, so you can trace the live flow.
  4. Click 'New Puzzle' for a freshly scrambled, always-solvable layout.

Each tile is a piece of pipe. Click a tile to rotate it 90°. Turn the pipes so an unbroken path of water connects the blue source to the green sink. Lit (cyan) tiles are currently fed by the source.

Frequently asked questions

How do I rotate a pipe?
Just click (or tap) any pipe tile — it rotates 90 degrees clockwise each click.
How do I know I've solved it?
When a continuous flow links the blue source tile to the green sink tile, every connected pipe lights up cyan and a success message appears.
