Your game progress on Android OS devices can be saved by linking to your Google Play account.
 
If you would like to play using the same profile on multiple Android devices:
  1. Make sure your game profile is linked to your Google Play account.
    Note: if you find that your game profile is not linked to Google Play account at this stage, please contact our support team via Help button in the game settings.
  2. Open the game settings screen in your new profile, press "Connect" button, and select the Google Play account connected to your game profile in the pop-up window. Your progress will be synced automatically.
Note: you can’t play on more than one device at once.
If you switch your device, tap “Refresh Session” when you launch the game to sync your game progress.
