If you do not have a Facebook account, or if you do not want to use it to save your game, you can play with friends through the Game Center app.
  • To do so, register a new account, or use your existing one if you already have one. If you’d like to create an Apple ID, press here.
  • To sign in to your account using an existing Apple ID (usually it is your email address) press here.
  • If you have previously made purchases in the iTunes & App Store, or have registered in the Game Center, you can use the same Apple ID as you had used within these systems.
