Let’s get you back
to your puzzle.

Help with Sudoku Arena accounts, saves, purchases, and gameplay.

Accounts and cloud saves

Open Settings in the game to link your guest player to an email address. Use Sign in with an email code on another device to return to the same account. Linking your account before uninstalling protects progress that has successfully synced.

If an email does not arrive, check spam and confirm the address you entered. Never share a verification code with anyone, including support. For saves that differ between devices, review the game's conflict choices before selecting the progress you want to keep.

Purchases and restoring ad-free access

Use the store account that made the purchase, then choose Restore purchases in the game's store. Purchases are tied to the relevant app store; signing into the same game email does not automatically transfer a purchase between Android and iOS.

For billing or refunds, use Google Play purchase support or Apple purchase support. You can also contact us with the product name and order reference. Do not send full card numbers.

Playing offline or with friends

Solo puzzles work offline. Multiplayer, email sign-in, cloud sync, and store restoration need an internet connection. If a match disconnects, check your connection before returning to the game.

Privacy and account deletion

Read our privacy policy or follow the account-deletion instructions. You can request account deletion by email even if you no longer have the app installed.
