When you register an account, you are given the option to add an existing player as your referral to Flight Rising.
What are referrals?
Referrals reward the player you listed as your referral with a one time gift of 50 gems when you make your first gem purchase. After that, whenever you make a gem purchase they receive some gems from Flight Rising, too!
Can I add someone as my referral after I register?
No. Referrals can only be added at the time of registration.
What if I want to keep my gem purchases private?
You can send Flight Rising Support a request to unlink your account from theirs. Be sure to use the email address registered to your account when you do!
