Frequently Asked Questions
How do I restore my Pro purchase?
Open the app, tap the GO PRO chip on the home screen, then tap Restore purchase at the bottom of the Pro upgrade screen. This will restore your Sudoku Game Pro unlock on your current device.
Make sure you are signed in to the same Apple ID or Google account that you used for the original purchase. Restore works for both Sudoku Pro tiers: Yearly ($2.99/year auto-renewable subscription) and Lifetime ($9.99 one-time, never expires).
How do I cancel my Sudoku Pro Yearly subscription?
Sudoku Pro Yearly auto-renews each year until canceled. You can cancel at any time:
- iOS: Settings > [your name] > Subscriptions > Sudoku Pro > Cancel Subscription
- Android: Google Play Store > Menu > Payments & subscriptions > Subscriptions > Sudoku Pro > Cancel
Canceling stops future charges. Your Pro access remains active until the end of the current paid period. Sudoku Pro Lifetime is a one-time purchase and does not auto-renew — there is nothing to cancel.
How do I delete my data?
All your data is stored locally on your device. Sudoku Game does not use accounts or cloud sync, so nothing is stored on our servers.
To delete your data:
- iOS: Settings > General > iPhone Storage > Sudoku Game > Delete App
- Android: Settings > Apps > Sudoku Game > Storage > Clear Data
Uninstalling the app removes all data completely, including saved games, statistics, daily challenge streaks, trophy wall records, hint tokens, and Pro status. There is no way to recover this data after deletion.
How do I manage ad preferences?
You can change your ad personalization settings at any time:
- iOS: Settings > Privacy & Security > Tracking
- Android: Settings > Privacy > Ads
- In-app: Settings > Privacy
You can also remove all ads permanently by upgrading to Sudoku Game Pro.

How do hint tokens work?
Every puzzle gives you 3 free hints. If you need more, you can earn additional hint tokens in several ways:
- Daily challenges: Complete the daily challenge to earn a bonus hint token.
- Rewarded videos: Watch an optional video ad to receive 3 hint tokens.
- Go Pro: Upgrade to Sudoku Game Pro for unlimited hints on every puzzle — either Yearly at $2.99/year (auto-renewable) or Lifetime at $9.99 (one-time, never expires).
Hint tokens are saved across puzzles and persist between sessions. Your token balance is shown on the game screen near the hint button.
