Please note that you can transfer progress only to the same platform (from Android to another Android and from iOS to another iOS).

To continue playing on another device, you need to sign into a social network and activate the Cloud Storage that will save your current game progress. You can authorize through the game Start Menu, pressing the required button at the bottom of the screen.

To copy your game progress to another device, you need to complete just the same authorization procedure on it. After that the system will identify you and offer you to download your game progress.

Please note: each time you chose to continue playing on another device you will have to repeat this process to ensure you have the latest version of your progress on your current device. Otherwise you may end up losing a part of your progress.
