AdVenture Ages uses Game Center and Google Play to backup and restore game progress and purchases. Make sure you are synced before changing devices or uninstalling the app!
If you have synced your game, your purchases will transfer between devices as long as you are logged into the same account.
If you need help transferring between Android and iOS, reach out to our support team with both your new and old Account IDs. Our support team will see what they can do to help!
