Frequently asked questions

Does the app need an internet connection?

No. Sudoku works fully offline — every puzzle, including the daily puzzle, is built into the app.

Are there ads or in-app purchases?

No ads and no in-app purchases.

Where are my games and settings saved?

On your device only. Nothing is sent to a server, and there is no account to sign in to.

Will my progress move to a new iPhone?

Yes, if you restore your new iPhone from an iCloud or computer backup of the old one. Deleting the app deletes its data.

How do I make the game easier or harder?

Open Profile → Game and pick an assistance level, from Beginner (every aid on) to Expert (no aids, no hints and a limit of three mistakes). Choose Custom to set each option yourself.

How do I change the language?

Profile → General → Language. The app is available in English, Deutsch, Français, Italiano, Suomi and Türkçe.
