Pipe Connect

Every square holds a pipe piece — an end, a straight, a bend or a junction. The pieces have been scrambled by rotating them. Turn them back so that every pipe connects to the central source and no pipe end points into a wall or an empty side.

Each board is generated from a real network that spans the whole grid, so a solution always exists. Connected pieces light up, so you can see your progress as you go.

1. Click or tap a piece to rotate it clockwise; right-click to rotate it back.
2. Pieces connected to the source (the gold dot) light up.
3. Connect every piece with no open ends to win.

• Start at the edges and corners. A pipe end on the border can only face inwards, which fixes many pieces immediately.
• Straights next to walls must run along the wall.
• Avoid closed loops. The network has no cycles, so two pieces that would close a ring cannot both point at each other.
