Pipe Connect

Every tile holds a piece of pipe. Turn the tiles until all of it joins up into one network fed from the source, with no loose ends. Three grid sizes, a timer, and your best time for each size is remembered.

How to play

Tap a tile to turn it a quarter turn clockwise. Right-click it, or press and hold on a phone, to turn it the other way.

Tiles joined to the source light up in colour; grey tiles are not connected yet. A pipe end that faces the edge of the grid, or at a tile that does not meet it, still needs turning.

The puzzle is solved when every tile is lit and nothing is left open. Switch on “Lock” and tap tiles you are sure about so a stray tap cannot turn them; “Take back” undoes your last turn.

A tip

Start at the edges: a pipe can never face out of the grid, so edge and corner tiles usually have only one way to sit. Every fix there settles its neighbours.

With the keyboard, use the arrow keys to move between tiles, Enter or Space to turn one clockwise, Shift+Enter to turn it the other way and L to lock it.
