How to Play

Form a loop with the numbers as hints.

• Clicking on a edge darkens a line. Clicking on them again undarkens it. A double click erases the line.
• The number inside the squares indicates the number of lines that should be drawn around the four lines that surround it. A square with no number can have any number of lines around it.
• There is only one solution.
• There can only be a single loop with no loose ends.
