Nikoli loop puzzle (Loop the Loop / Fences): draw a single non-crossing closed loop along the dots so each number has that many of its sides on the loop. Unique solution. Free, no ads.
How to play
- Tap an edge to cycle it: line, then ✕ (no line), then empty.
- Each number is how many of that cell's four sides the loop uses.
- The loop is one continuous ring that never crosses or branches.
- Every dot ends with 0 or 2 lines; every board has a unique solution.
