How do I restore the full version?
In the shop, choose Restore Purchases using the Apple Account that made the purchase. Connect to the internet for verification; restoring does not charge you again. iCloud progress sync does not transfer purchase rights. Once the unlock is verified, you can play offline.
Moving devices and iCloud sync
Sign in to the same iCloud account and enable iCloud Drive on each device, then turn on automatic progress merging separately in this app’s Settings on each device. Sync is off by default. Stay online with the app in the foreground and wait for the sync status to update. Completed prints, methods, custom puzzles and stars can merge; unfinished work lines, device settings and purchases do not sync. Export a full backup before moving devices.
Signing in to Game Center
Sign in to Game Center in iOS Settings, then return to Friend Duel or the time rankings. Each player should use their own account, a compatible app version and an internet connection. Do not share your Apple Account password with the developer or other players.
How do I request a refund?
For purchases billed by Apple, visit reportaproblem.apple.com, sign in with the Apple Account used for the purchase, choose to request a refund and follow the website’s steps. Apple determines eligibility and the outcome. The developer cannot guarantee or issue the refund directly.
Backups, merging and undoing a restore
Export a full backup in the app’s Settings before restoring a file. Merging keeps valid progress and better records from both saves; replacing switches to the imported progress and turns iCloud sync off. After a successful restore, use Undo Last Restore to return to the previous progress. Undo also turns sync off. Keep the original exported file.
Contact Player Support
For game issues, failed imports, or suggestions, email gavinho020604@gmail.com. Describe the issue and include your app version, device, and iOS version. You may attach screenshots. Do not include passwords or other unnecessary private information.
Can't Connect to a Friend Duel?
Both players need compatible app versions, Game Center sign-in and an internet connection. After one player creates a room, they can share an invitation link. Their friend opens it and confirms joining, or enters the six-digit room code. If a match is already in progress, switching invitations first asks you to confirm leaving it. Keep the app in the foreground while waiting for a match.
Protect Your Progress
You can export a full backup in Settings. Keep a copy before changing devices. You can also choose to enable iCloud sync for completed orders, prints, print methods and stars; your local unfinished work line and settings stay as they are. Manual restoration can merge or replace data. Replacing or resetting turns sync off, while older cloud saves are kept.
Full Version and Restoring Purchases
Play the first six chapters (150 orders) free. One purchase unlocks the remaining 350, advanced modes and Blossom/Mint styles. There is no energy system or subscription, and retries and replays cost nothing extra. The purchase button shows the App Store's local price. Restore with the same Apple Account. Unlocked content works offline; free content does not require iCloud.
Language & Reading Settings
Switch between six languages instantly, change the theme, and reduce motion in app Settings. The app also follows iOS text size and Reduce Motion settings.
