Sudoku Zen - Calm Numbers

Five grades from Gentle to Master, a daily puzzle shared by everyone, and no clock demanding anything of you. Free to play, for as long as you like.

Nine rows, nine columns, nine boxes, and one number that belongs in each square. That is all Sudoku has ever been, and it is enough.

Sudoku Zen adds nothing to it except quiet.

FIVE GRADES • Gentle — a warm start, with nothing to untangle • Calm — steady, unhurried logic • Focused — asks for your full attention • Deep — pairs and chains, for when you have time • Master — for the patient mind

Every puzzle is generated with exactly one solution and is solvable by reasoning alone. You will never be asked to guess.

A DAILY PUZZLE One puzzle a day, the same puzzle for every player in the world, and a streak that grows for as long as you keep coming back. Miss a day and the streak resets — unless you have a freeze saved.

BUILT FOR THINKING • Notes, with a single tap to fill in every candidate • Peer highlighting, so the row, column and box you are working in are obvious • Matching-number highlighting across the whole grid • Unlimited undo • Mistake counting you can turn off entirely

NOTHING HURRIES YOU No lives. No energy. No countdown. The timer can be hidden and forgotten. Put the app down mid-puzzle and it will be waiting exactly as you left it.

YOUR NUMBERS Puzzles finished, best times by grade, your longest streak and the hour of day you play most. Kept on your device, and yours.

MADE WITH CARE Full VoiceOver support, with every cell announced by its value, row, column and box. Reduce Motion honoured. A light and a dark theme that both work in real light.

No accounts. No advertising. No third-party tracking. Plays entirely offline.
