You can only synchronize your game progress on multiple devices if your aquarium is linked to one of the social networks supported by the game. In addition:
- You must have the latest version of the game on both devices
- Synchronization through Google Play is only available within the platform on which the original game was installed (i.e. you can't sync devices on iOS and Android using Google Play).

Here's how to sync your devices:
1. Install the game on the second device and launch it.
2. Make sure you have a stable internet connection.
3. Connect the game to the same social network account you use on the first device.
4. A window asking you to download your saved game from our server will pop up.
5. Select Yes and type CONFIRM. Your game progress will be transferred.

ATTENTION! The downloaded save file will completely replace your current progress on the new device.
