FIVE WAYS TO PLAY SUDOKU

HOW TO PLAY SUDOKU
Fill every row, column and box with the numbers 1 to 9 (1 to 6 on Beginner boards, 1 to 16 on Giant boards) so that no number repeats. Use logic, not guesswork – each puzzle has a single solution.

HOW TO PLAY KILLER SUDOKU
Follow the classic rules, and make the digits in each dashed cage add up to the small number in its corner. A digit never repeats inside a cage.

WHY PLAY SUDOKU?
Sudoku is one of the most loved number games and logic puzzles in the world. A few minutes a day is a calm way to practise focus and logical thinking – whether you want a quick easy sudoku on a break or a long, hard sudoku in the evening.

GOOD TO KNOW
Sudoku – Classic Puzzle Board is free to download and play. It contains ads and offers optional in-app purchases: gems, ad removal and the Sudoku Plus subscription, which renews automatically until you cancel it in Google Play. Classic puzzles play offline; the league, leaderboards and cloud save need an internet connection.
