Every player has a recruitment code that can be used to invite non-playing friends.

 

You may send the invite code through Facebook or email to the desired recipient through the game.

Once an invitation is accepted, both you and the invitee will receive gifts for using this code.

 

You can use your code to invite several players; however a new player can only be invited by one existing player.

 

Note that this feature only works for players on the same server and platform.
