How Do I Play Across Multiple Devices?
It is possible to play the game across multiple devices on the same platform i.e. Multiple iOS devices at the same time or Multiple Android devices at the same time. However, it is not possible to play across platforms i.e. iOS > Android or Android > iOS
In order to transfer your progress from one device to another, you must be signed-in using Google Play Games (Android) or Game Center (iOS).
All you need to do is sign in with the same Google Play Games/Game Center account as you did on the previous device to restore your progress.
