How to play Sudoku
Fill the 9×9 grid so every row, column, and box holds 1 to 9.
The rules
- Fill every empty square with a digit from 1 to 9.
- Each row, each column, and each 3×3 box must contain every digit exactly once.
- The dark digits are fixed clues, and there is exactly one solution.
How to get started
- Pick a 3×3 box that is nearly full. Which digits is it missing?
- Tap an empty square in that box. Any digit already in its row or column cannot go there.
- When only one digit is left for a square, tap it on the number pad.
- Stuck? Turn on Notes and pencil in every digit a square could still take. A square with one note is ready to fill.
- Keep scanning rows, columns, and boxes. Ask the coach whenever you want a nudge.
A tip
Look for a row, column, or box with only one or two empty squares.
