How to play Pipes

Tap the tiles to rotate them and join every pipe into a single network. Water flows from the source through everything that is connected — fill the whole board to win.

How to play

1. Tap a tile to rotate it 90° clockwise (right-click turns it back).
2. Every pipe end must meet a pipe end on the neighbouring tile — nothing may point off the board or into a wall.
3. All pipes must form one connected network without loops.
4. Water spreads from the source through everything that is connected.
5. When the water fills every pipe, the puzzle is solved.

Free online pipe puzzle

Pipes (also known as Net or FreeNet) is a logic puzzle: every tile holds a piece of pipe — a straight, a bend, a T-junction or an end — and your only move is to rotate it. Every level on PuzzleWorld is generated as a single network, so there is always a way to connect it all.

Start at the edges and corners: pipes can never point out of the board. End pieces next to each other can never face each other, and straight pieces on the border must run along it. Water shows which part is already connected to the source.
