Your Game Progress Is Safe!
Your progress is automatically saved — both on your device and in the cloud.
Whenever you play, your game data is uploaded to the cloud using your Google Play (for Android) or iCloud (for iOS) account.
This means that if you switch to a new device, you won’t lose anything! Just log in with the same account, and your progress will be restored automatically.
Note: You won’t need to create a nickname or set a password to play.
