Rules:
Each puzzle consists of a rectangular lattice of dots with some clues in various places. The object is to link adjacent dots so:
1. The value of each clue equals the number of links surrounding it.
2. Empty squares may be surrounded by any number of links.
3. When completed, the solution forms a single continuous loop with no crossings or branches.
