How to Play Sudoku
Sudoku is a logic puzzle. Fill the grid so every row, column, and 3×3 box contains the digits 1–9 with no repeats.
The rules
- The board is a 9×9 grid split into nine 3×3 boxes.
- Some cells already show numbers — those are given clues and stay fixed.
- Fill empty cells with digits 1 through 9.
- Each digit may appear only once in every row, column, and box.
