Due to your game data being stored within the device you play on, there is currently no option to sync game data between devices. If you're playing on a phone or tablet and you need to transfer your progress to a new device, you can do so with the Save Progress and Restore Progress features in the settings menu.
Please note: Once the codes from your old device are used, the code from that device will no longer be able to be used in future transfers.
If you have any other questions, please feel free to use the Contact Us feature.
