To transfer your progress over, you need to first save your progress on your old device using one of our authentication methods you can see the in-game Settings.
Then, once you install the game on your new device, go to “Save/Load Progress” in your Settings after completing the tutorial and tap on the same login method that you used when saving your progress on your old device.
Follow the on-screen instructions and your game progress should now be transferred to your new device!
