Loop
Draw one closed loop that satisfies every numbered clue.
How to play
- Draw a single continuous loop along the grid edges.
- Each numbered cell tells you how many of its four edges the loop uses.
- The loop never crosses, branches, or leaves a loose end.
Controls
- Tap an edge to add or remove a loop segment.
Example
┌─┐ │3│ · ·
A “3” cell uses exactly 3 of its 4 surrounding edges.
Tip · 0 and 3 clues and the grid corners are the safest places to start.
