Sudoku

Sudoku is a popular logic puzzle. Solving it requires concentration and logical reasoning, rather than calculations or advanced mathematics. Playing regularly can help you practise these skills.

Sudoku Rules

Fill the 9x9 grid with the digits 1–9 so that each row, column and 3x3 box outlined by thick lines contains every digit exactly once.

• Each digit from 1 to 9 appears exactly once in each column.
• Each digit from 1 to 9 appears exactly once in each row.
• Each digit from 1 to 9 appears exactly once in each 3x3 box.

Classic Sudoku uses a 9x9 grid. Beginners can try Mini Sudoku first, or print puzzles for children to solve with a pencil.
