- Start with the short paths of 1, 2 and 3, and then move up to longer ones.
- Don’t forget the squares at each end when counting path lengths.
- Paint partial paths whenever possible. This will usually help with neighboring paths as well.
- Every new path you paint might help in a next step.
- Determine which clues pair with which. Using odd/even parity can help with this process.
- Never guess! Paint each path only after you are sure it is unique.
Note: There is only one unique solution for each puzzle.
When solving on paper
- Use a soft erasable pencil and a high quality eraser.
- Draw paths as thin lines and paint the squares later.
- Lightly draw temporary paths to see which pairs of clues are blocked from others.
- Experienced solvers can paint with markers for outstanding results.
When playing on a computer
- Use Preferences options in toolbar for a better personal playing experience.
- Paths can be started from both ends, and then joined together later on.
- Path fragments can also be painted by starting from any empty square.
- Any path can be deleted by double-clicking the mouse or using the Delete key.
