✉️ ehsan@allionapp.comHow do I get extra hints or an extra life?
Watch a short rewarded ad from the game-over or hint screen to get an extra life or hint.
Do I need an account to play?
No. Sudoku Origin works instantly with no sign-up. Your progress (level, XP, coins, streak) is stored automatically so it's there next time you open the app.
How do I reset my progress?
Uninstalling the app removes all data stored locally on your device. To also delete your progress stored on our servers, email us at
ehsan@allionapp.com and we'll remove it.
How do I switch between Light and Dark mode, or change the language?
Go to the Profile tab inside the app — you'll find Theme and Language settings there.
Does the app show ads?
Yes, Sudoku Origin shows banner and interstitial ads, and offers optional rewarded ads in exchange for extra lives or hints. See our
Privacy Policy for details.
Email ehsan@allionapp.com with a description of the issue and, if possible, your device model and iOS/Android version. We usually reply within a few business days.
