Tap to rotate

Pipe

Pipe rotation puzzle — rotate each pipe to connect the source to the drain. A fresh layout every game.

How to play

Each cell of the grid holds a pipe piece. Tap a cell to rotate it 90° clockwise.

Connect the top-left source to the bottom-right drain. Connected pipes light up.

Finish to advance to a bigger grid. There's no time pressure — solve and grow.

Goal: clear as many levels as you can.

Tips & strategy

Since there is no clock, this is a logic puzzle to be reasoned out, not raced. Start from the fixed points — the source and the drain — and the edge and corner pieces, because tiles against a wall have far fewer sensible orientations and often only one. Lock those certainties in first and the middle of the grid solves itself around them.

Trace the path as a single connected line from source to drain rather than rotating tiles at random. A piece that must carry the flow has its direction forced by its neighbours, so work along the chain, each connected pipe constraining the next. If you get stuck, look for a tile you rotated on a guess and back it out; in a sound layout every piece has a determined orientation once its neighbours are set.
