How to solve a sudoku
Every row, every column and every box must contain each number exactly once. Look for a row, column or box with only one empty square first: the missing number is the only one not used yet.
| Size | Numbers | Boxes | Empty squares (easy / hard) |
|---|---|---|---|
| 4×4 | 1–4 | 2×2 | 6 / 10 |
| 6×6 | 1–6 | 2×3 | 14 / 22 |
| 9×9 | 1–9 | 3×3 | 36 / 50 |
Sudoku builds logical thinking. No maths is needed: the numbers are just symbols.
