Pipe Connect

Every opening needs a matching neighbor

Rotating a pipe changes where its openings point. An opening must meet the facing opening of the adjacent pipe; an unmatched end is a leak. Two boundary openings are required: the inlet points left from the top-left tile, and the outlet points right from the bottom-right tile. Other openings must stay inside the board.

A corner pipe near the edge often has fewer plausible orientations than a pipe in the center. Set the constrained pieces first, then follow their connections inward. A closed loop by itself is not enough if it leaves another part of the network disconnected.

Check the whole network after a local change

Fixing one connection can break another connection on the same piece. After rotating a junction, inspect every branch rather than only the opening you wanted to match. Finish with every tile connected to the inlet, the outlet open and no leaks.

Choose a 4 × 4 board for a smaller planning problem, then try 5 × 5 or 6 × 6. The daily board uses 5 × 5. The native hint highlights a pipe to work on; Undo reverses a rotation when you want to compare orientations.
