🎯 The Objective

Draw a single continuous loop that passes through some edges of the grid, following the numbered clues.

🔢 The Clues

Numbers in cells indicate how many edges of that square are part of the loop:

• 0 - No edges touch the loop
• 1 - Exactly one edge is on the loop
• 2 - Exactly two edges are on the loop
• 3 - Exactly three edges are on the loop

Empty cells can have 0, 1, or 2 edges (never 3).

✏️ Drawing the Loop

• Left click edges to add them to the loop (draw black lines)
• Right click edges to mark them as definitely NOT part of the loop (mark with X)
• Click again to undo and return to unknown state

📏 The Rules

1. The loop must be one continuous path (no breaks)
2. The loop must close on itself (start and end at the same point)
3. The loop cannot cross itself
4. The loop cannot branch (max 2 edges per grid point)
5. Every clue must be satisfied

💡 Tips & Strategies

• Start with 3s: Cells with 3 edges are the most constrained
• Use 0s and 1s: They eliminate many possibilities
• Corner cells: Pay attention to corners with clues
• Mark impossible edges: Right-click helps narrow down options
• Visual guidelines (5×5 only): Gray lines show valid possibilities
• Think ahead: Consider how the loop must close
