○ white pin — a right color in the wrong spot
Pins are not in peg order. Use them to work out the code within 10 tries.

Tap a cell to fill it, or drag to paint a straight line. Tap a filled cell to clear it.
Switch to ✕ Cross (or right-click) to mark cells you know are empty.
When a line matches its clue, its numbers turn gray and its remaining cells are crossed out automatically.
Fill every line to match its clues to solve the puzzle.
