A quiet Sudoku for Android
Nine rows. Nine columns. Nothing else on the screen.
No ads, no timers you didn't ask for, no pop-ups between you and the next cell. Three free puzzles a day at each difficulty, or unlock every one with a single purchase.
Android now. iOS later.
How it plays
What the app does, and what it leaves out.
No ads, no interruptions
Nothing appears between you and the board. Not between puzzles, not after a mistake, not ever.
Pencil notes that stay put
Jot the digits a cell might take. Each sits in a fixed spot, one top-left to nine bottom-right, so you read them by place.
Plays offline
No connection needed. Puzzles you solve on a plane count the moment you are back.
Readable by design
Type you can read at arm’s length, light and dark modes, a high-contrast setting, and three text sizes.
Progress that follows you
Sign in and your level, XP and achievements come with you to the next phone.
A hint when you want one
Stuck? Hint fills one correct cell. The completion screen counts them, so you always know.
