What this one asks of you - mild spoilers
- Follow it and see it fail. Take a direction and keep applying the simpler rules. If the line paints itself into a corner, that direction was wrong - so the other one is right.
- Only way out. The line can leave a cell in only one direction - every other neighbour is already used, off the board, or a waypoint that is not due yet.
- Do not strand a cell. The line must pass through every cell. If going one way would leave a cell with no way in or out, that way is wrong.
Every one of these is explained properly in the Circuit guide.
