How to play sudoku
- Fill every empty square with a number from 1 to 9.
- Each row contains every number exactly once.
- Each column contains every number exactly once.
- Each 3 × 3 box contains every number exactly once.
Why large print?
Bigger numbers mean less eye strain, fewer mistakes and more fun – ideal for older players, people with low vision and anyone who likes a calm, clear game.
