I think your accounts have to use the same email if you want to sync them @ShaDisz

If you are using different emails for separate accounts I don't think they can be synchronised.

To sync your game to a new device or across several devices all you need to do is create a King account.

Once you have a King account all you need to then to sync your game is to use your email and password to sign into your game.
