Connecting your game with an account (Facebook or Username) allows you to play on multiple devices if you log into the same account. It also ensures that you can access your game later even if you lose access to your device. Because of this, we strongly recommend setting up an account.

To set up an account, tap on Menu (the button in the lower left corner filled with 9 squares) and then Account Info.

In order to sign in to an account on your new device, play through the tutorial. Once you're able to access Account Info in the Menu, press "Change User" and then "Load." From here, you can safely sign in to your other account without fear of losing your saved game.
