Pipe Connection Puzzle: player questions
Where should I start?
Corners and border tiles have fewer possible orientations. Connect their available ends inward before working through the center.
Does a lit tile mean its rotation is correct?
No. Lighting shows connection to the highlighted source, not proof that the tile is in its final orientation.
Can the finished network contain a loop?
Not in this edition. All tiles must form a connected network without a closed circuit.
What does locking a tile do?
A lock protects a tile from accidental rotation. It records your decision; it does not check the decision for you.
What if two ends almost meet?
Both neighboring tiles need an end facing their shared border. An end pointing toward a blank side remains disconnected.
Why are border tiles helpful?
This edition does not wrap around the board. An opening cannot connect through the outside edge.
How do I recover from a wrong rotation?
Use Undo to reverse moves. You can also unlock a tile and rotate it again.
How are the levels different?
Easy uses 5×5 tiles, medium 7×7 and hard 9×9. Larger networks create more branches to inspect.
Can I play with a keyboard?
Focus the board, move with arrow keys, rotate with A or D, and lock a tile with S.
How can I compare daily puzzles with a friend?
Use Share to copy the date and level link. It identifies the starting puzzle, without copying your progress.
