Unfortunately, Game Center and Google Play only record your achievements and will not save your game's progress. Currently, the only way to save your game to an account and access it across multiple devices is by using a Jam City ID account.

You can access the Jam City ID login by tapping the gear button in the upper right corner to bring up the Settings menu.

For more information about the login process, please refer to our "How do I save my game to an account?" and "How do I load a game that was saved to an account?" FAQs.
