How to play
- Fill the 9×9 grid with digits 1–9.
- Each row, column, and 3×3 box must contain every digit exactly once.
- Use notes/pencil marks if the UI offers them — they help track candidates.
Strategy tips
- Start with digits that already appear eight times on the board.
- Scan rows and columns that are nearly complete to place singles.
- On harder tiers, look for naked pairs to eliminate candidates.
