Rules and play
Daily Sudoku Game Rules
No repeat in a row, column, or box. Given digits stay. Fill empties until the board is complete and legal. Notes (pencil marks) record candidates. A digit that fits a row can still be banned by its box. New puzzle daily.
- Fill Daily Sudoku so each row, column, and 3×3 has 1–9 once.
- Given numbers cannot be changed.
- Repeats in any house are illegal.
- A new 9×9 publishes each day.
