## How to play

### Goal

Draw a single continuous loop that never crosses or branches. Each number says exactly how many of that cell's four sides the loop uses; blank cells can have any number of sides. Every puzzle has one solution — you never have to guess.

### Rules

• The loop is one closed line and never crosses itself or splits
• A numbered cell must have exactly that many of its four edges on the loop
• A 0 means none of that cell's sides are used
• Blank cells have no constraint
• Every dot the loop reaches has exactly two segments meeting at it

### How to Play

• Tap the gap between two neighbouring dots to place a segment; tap it again to mark an X (no line there), and once more to clear it
• Marking X's on sides you have ruled out is what makes the deductions visible
• Use Check to flag any cell whose number can no longer be met, Hint to reveal one correct segment, and Undo to step back
• Keyboard: arrows or WASD move the cursor between segments, Enter or Space places a line, X crosses it out, Backspace clears, Z undoes

### Tips

• Start with 0s — cross out all four of their sides straight away
• A 3 next to a 0, or two 3s side by side, forces several segments at once
• Corners with a 1 or a 3 have only one sensible shape — fill those first
• Keep every dot at zero or two lines; a dot with one line must continue

### Difficulty

The grid grows with difficulty: 5×5, 7×7 and 9×9, with fewer clues each step. A bigger, sparser board means longer chains of deduction — never guesswork.
