Lumi Trace - One Line Puzzle

Lumi Trace is a one-line drawing puzzle: trace every line of the figure in a single stroke, without going over the same line twice. It looks like string art on a cork board, with brass pins and soft thread.

HOW TO PLAY
• Touch a pin and drag along the lines.
• Cover every line with thread to clear the puzzle.
• You can lift your finger and continue from the same pin.

NEW RULES AS YOU GO
• One-way arrows: these lines can only be traced in one direction.
