Controls
Select a cell first, then enter numbers. Keyboard digits work on desktop.
- Pick an empty cell before entering a number. Given clues cannot be changed.
- Desktop supports keys 1-9, while Delete / Backspace clears the current cell.
- Each board gives you 3 hints. A hint fills the selected empty cell first, or a random empty cell if none is selected.
- Wrong entries are rejected instead of written to the board, but mistakes are still counted.
- Clearing the full board advances you to the next level automatically.
