How to play Loopy
Solve three handcrafted Slitherlink puzzles. Each number gives the count of loop edges around its cell; the finished lines must form one connected, nonempty loop with exactly two lines at every used vertex. Any valid solution is accepted.
Controls
- Click an edge to cycle empty, line, and cross; right-click reverses the cycle
- Tab to an edge, then Enter or Space to change it
- Choose a puzzle to switch levels; Restart clears it; Hint adjusts one edge
Tips
- Use a 3 or 0 to determine nearby edges quickly.
- Check that every used vertex has two lines and that all lines connect into one loop.
