You can only synchronize your game progress on multiple devices when your aquarium is associated with Facebook.

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 telling you to download the 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.
