What is Sudoku?
Sudoku is a logic puzzle on a 9×9 grid divided into nine 3×3 boxes. Each row, column, and box must contain the digits 1 through 9 exactly once. No arithmetic is required—only deduction.
How to play
- Scan for obvious singles—cells where only one digit fits.
- Use notes to track candidates when several digits might work.
- Check the row, column, and box together before committing a number.
- Reset restores the original puzzle; New puzzle shuffles a fresh grid.
