If your current Rise of Firstborn account is linked to Google Play, Apple Game Center, or Facebook, you can connect your Google / Apple / Facebook accounts that you have linked to on other devices and import your game data. When you tap the Google, Apple, or Facebook account that you linked on the account link screen, the linked account information is automatically retrieved.
※ Please note that if you are using a guest account that is not linked to the account you are currently using, when you bring up an existing account, the account you are currently using will not be available.
In addition, Google Play and Apple Game Center account linking can only be used to transfer game data between Android models and iPhone models, respectively. In other words, if you are using a linked account through Google Play, you will not be able to transfer your game data to an Apple device (or vice versa).
※ If you would like to switch between Android and Apple devices, you will need to link your Rise of Firstborn account through a Facebook account.
