You can back up your game progress via Google Play Games or iCloud Game Center, depending on whether you use an Android or iOS device.
To connect to Google Play Services, follow these steps:
- Install the Google Play Games from the Play Store
- Go into the game’s settings
- Tap “Sign in with Google”
If in the case that you do have Google Play Services installed on your device, but the game still does not save your progress, please do the following:
- Go into the game’s settings
- Tap “Sign in with Google”
To connect to iCloud, check the following:
- Make sure you are logged into the Game Center (Settings -> Game Center)
- Make sure your iCloud Drive is turned on (Settings -> Apple account settings -> iCloud)
If your progress is backed up, simply connect the same account to your new device, and the progress should be restored from your Cloud back-up.
