If you logged in or connected your account to Facebook previously, all of your progress will be synced across all your devices. Logging into Facebook also ensures that you can resume where you left off in the event that you lose your device or purchase a new device.
Alternatively, you can also tie your account via email address. You just have to:
- Go to your Profile.
- Tap on the pencil icon (edit Profile).
- Fill in the email address you want to use under SAVE MY PROGRESS.
Please note that the email should be an active one, as we will be sending a verification code to that email so you can log in to the game.
