Guest accounts are bound to the specific device where the game was first installed and cannot be transferred directly.
If you want to transfer your game to a new device, it's highly recommended that you should bind your game with your Facebook account at first. After that, you can install Jackpot Crush app on the new device through App Store or Google Play Store, and log in with your Facebook to get back the original game account.
Important: Do not uninstall the app while using a Guest Account, as your progress may be permanently lost.
