Linking your game to Facebook is the best way to save your game progress. Facebook login is available within the Chef Circle tab and Settings screen.
Linking to Facebook will also help you play the same game on multiple devices. To load your game progress on another mobile device you simply need to launch the game and log in with the same Facebook account.
Remember: The game progress is saved when you quit the game. So we recommend you quit your game in the current device before moving the game to a different device.
