iCloud synchronization

Sudoku Studio synchronizes player progress and saved games through your private iCloud database when iCloud is available. Puzzle-cache data and device preferences remain local.

  1. Confirm that the same Apple Account is signed in on each device.
  2. Open iOS/iPadOS Settings → your name → iCloud and confirm iCloud is available.
  3. Open Sudoku Studio Settings → iCloud Sync and check the shown status.
  4. Choose Sync Now, then allow a short time for another device to receive the update.

If iCloud is temporarily unavailable, you can continue playing. Progress remains on the device and sync should resume when iCloud becomes available.

Premium and purchases

Premium is a one-time App Store purchase. It removes automatic interruption ads.

  1. Use the same Apple Account that made the purchase.
  2. Open the Premium screen in Sudoku Studio.
  3. Choose Restore purchases.

Apple handles billing and refunds. For a refund request, use Apple's purchase-support service.

Ads and rewarded hints

Every hint requires a rewarded video, including with Premium. Premium removes automatic interruption ads, not hint videos.

If no hint video is available, check your connection and try again later. Availability can depend on consent, region and current ad inventory. A hint is awarded only after the video reports completion.

Saved games and progress

Active puzzles save automatically. Use the Continue card on the home screen to resume. If an older state appears, keep the app open briefly while iCloud finishes syncing and avoid playing the same puzzle on two devices at once.

Privacy choices and deletion

Where required, ad consent can be reviewed through Settings → About → Privacy choices. To remove synchronized progress, open Settings → iCloud Sync → Delete iCloud Data.
