Little diagonals. No loops.
Every line has two ends.
Draw one diagonal in each square. Each numbered corner must touch exactly that many lines. Never close a loop.
Tap cycle: blank → / → \ → blank
Beautifully untangled.
Every number met. Not a loop in sight.

Three rules. One quiet puzzle.
- Fill every square. Tap to cycle from blank to /, then \, then blank again. You need one diagonal in every square.
- Match each numbered corner. A 2 needs exactly two lines ending at that point. A 0 must touch none. Unnumbered points have no count rule.
- Never close a loop. The diagonals may form separate branches, but not a closed path, even around unnumbered points.
Green numbers have the right count right now, but the board is not solved until every square is filled and there are no loops. Red numbers cannot be met with the current lines; red lines belong to a loop. Undo or change a line to fix them.
Use Undo to step back. Restart clears the current attempt but keeps completed marks and your best result. On small screens, swipe larger boards sideways or choose Fit whole board.
Keyboard: Tab to a square, use arrow keys to move, and Enter or Space to change it. Progress stays in this browser when storage is available.
