How to play Sudoku
Fill the 9×9 grid so that every row, every column, and each of the nine 3×3 boxes contains the numbers 1 to 9, with no repeats. Start with the rows, columns or boxes that already have the most numbers filled in.
Sudoku builds logical reasoning and perseverance, no maths required, just careful thinking. Looking for more puzzles? Try a word search or a maze.
