If your game is connected to a Facebook account, you can play the game on multiple devices.
To sync your game on multiple devices:
- Connect your game to Facebook on your old device
- Install the same version of the game on your new device, and connect the same Facebook account
- Choose if you'd rather transfer your local saved game or the saved game on the server
- Tap on that saved game in the pop-up window
- Enter "CONFIRM" to finish the process
