The Game Center app (installed on your iOS device by default) automatically saves your game data and allows you to play on multiple devices without losing your game progress.
Here’s what you should do to play on multiple iOS devices with one profile:
  1. Make sure your game profile is linked to your Game Center account.
    Note: If you find that your game profile is not linked to Game Center at this stage, please contact our support team via Help button in the game settings.
  2. Open the Game Center app on the new device. Log into the Game Center account linked to your game profile. 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.
