You can play on the same Kingdom as your friends using the Friend Invite feature!
How to send friend invites?
In order to invite your friends to join you, you must first finish the tutorial. Once finished, select the Settings menu by tapping on the Gear icon, then tap “Invite Friends.” Copy this code and send it out to anyone who you’d like to join your Kingdom!
Note: Currently there is a limit of 1 friend invite per code generated.
How to redeem friend invites?
In order to redeem a code that someone has sent you, you must first finish the tutorial. Once finished, select the Settings menu by tapping on the Gear icon, then tap “Use Friend Code.”
Please keep in mind that when you redeem a Friend Invite, you will be starting a new account on the Kingdom you are redeeming the invite for. Your Game Progress & Purchases will not travel with you to the Kingdom your friend is playing on.
Note: If you want to play with your current Account & Kingdom in the future, you must bind that account to Facebook or Gamecenter before redeeming the Friend Invite.
