Tap a tile to rotate it clockwise. Join every pipe opening to a neighbouring pipe and connect the entire board. The filled dot marks the starting tile. End caps are allowed.

How to play
  1. Select a pipe to turn it one quarter-turn clockwise.
  2. Connect every opening to a neighbouring pipe. No openings may point outside the board.
  3. Connect all tiles into one network. Use a hint if you get stuck.
Tips and tricks

A few ideas that make Pipe Puzzle easier and more fun:

  • Start with the corners and edges. Pieces with only one possible fit are the easiest to lock in.
  • Follow the water. Tiles linked to the start glow, so look for where the glow stops and fix that spot.
  • Hints cost points. Try turning a tile all the way round before you ask for one.
About Pipe Puzzle

Play Pipe Puzzle online

Pipe puzzles belong to the family of tile-connection puzzles. A small local change can affect the whole network. Biuno generates a connected arrangement, then rotates its pieces for you to repair.

Why it works

You imagine how a piece will look after a turn and inspect how it joins its neighbours. The task uses spatial reasoning and checking a complete system.

These are the skills used during play; improvement outside the game is not established.
