How to play Pipe Link
- Each colour appears twice on the board as a pair of dots.
- Drag from one dot to its partner to lay a pipe between them.
- Pipes may not cross or overlap each other.
- The board is solved when every pair is joined and every empty square is covered.

Tips & strategy
- Work the edges and corners first. A pipe in a corner has almost no freedom, so its route is usually forced.
- Never leave a square stranded. If a cell can only be reached by one colour, that colour must pass through it.
- Filling the board is part of the puzzle, not a bonus. A solution that connects every pair but leaves a gap is not finished.
- If two pipes both want the same corridor, the one with fewer alternatives takes it.
Frequently asked questions
Must every square really be covered?
Yes. Connecting all the pairs is only half the task; a completed board has no empty squares left.
What happens if I drag across an existing pipe?
The pipe you cross is cut back to the point of collision, which makes rerouting quick — you rarely need to clear a colour by hand.
How are the boards made?
A full set of non-crossing paths is carved across an empty grid first, and only the endpoints are shown to you, so a complete solution always exists.
