Rules and play
Loopy Game Rules
A 0 bans every edge around that cell. A 1, 2, or 3 demands exactly that many loop edges. The finished line cannot branch at a dot, cannot stop as a dead end, and cannot form extra mini-loops. Every numbered clue must be exact. Left-click (or tap) to include an edge; right-click (or the exclude action) to mark an edge as impossible. Confirming a small circle while clues remain outside is the classic Loopy failure.
- Build one closed loop in Loopy that matches every numbered cell.
- A clue counts how many of that cell’s edges are on the loop.
- No branches, dead ends, or extra loops.
- Mark excluded edges as well as included ones.
