Pipes
Rotate the pieces of a broken pipe network so that water can flow from the central source out to every endpoint, with nothing leaking off the side.
Rules
- Click a piece to rotate it.
- Every pipe exit must line up with a matching exit on its neighbour. No exit may dead-end against a wall.
- Water flows from the central source through every connected piece.
Controls
- Click a piece to rotate it 90° clockwise.
- Right-click a piece to rotate it 90° counter-clockwise.
- On mobile, tap a piece to rotate it clockwise.
Tips & Tricks
- Edges and corners are the most constrained, so start there.
- A cap in a corner has only one valid rotation, and the same is true for tees and crosses tucked against a wall.
- Straight pipes along an edge can only run parallel to that edge.
- A tee against a wall always points its three exits inward.
- An orange outline means the connected pipes form a loop — water has to branch out from the source, never round in a circle.
