Common questions
- How do I restore Premium on a new iPhone or iPad?
- Open Settings in the app and tap Restore Purchases, signed in with the Apple ID you bought Premium with.
- What do I get with Premium?
- Every advanced lesson (Levels 5 and 6), Hard and Expert practice puzzles, and no ads. It is a one-time purchase, not a subscription.
- How do levels and exams work?
- Finish the lessons of your level, then practise until you reach 85% on two different days. The level exam is three puzzles solved without hints, with at most one corrected mistake each. Pass it to earn the level's certificate and open the next level.
- Why are hints turned off during an exam?
- The exam checks what you can do on your own. You can use all three hint levels in every other puzzle.
- The scanner read a number wrong.
- Tap the cell in the scan preview and correct it before starting. Good light and a flat page help. The scanner only accepts puzzles with exactly one solution.
- My progress isn't showing on my other device.
- Check that iCloud Sync is on in Sudoku Coach Settings on both devices and that both are signed in to the same Apple ID with iCloud Drive enabled.
- How do I change my ad or privacy choices?
- Settings > Share usage and crash data turns statistics on or off (they are off until you allow them). Settings > Ad privacy choices changes Google's ad consent. To stop tracking for all apps, go to iOS Settings > Privacy & Security > Tracking.
- How do I delete everything?
- Settings in the app > Delete all data. This removes your progress from the device and from iCloud Sync and cannot be undone.
