Friend Invitation rewards are only granted when a brand-new player registers/enters the game through your specific invitation link. If the invited friend has played before, or enters through another path, the reward will not be granted.
You won't get the reward if...
Your friend played the game before — Invitation rewards only apply to new players. If your friend has ever opened the game in the past (even once), they won’t count as new.
Your friend didn’t join from your invitation link — Your friend must open the game using your invitation link the first time they load the game. If they enter from the official account, a shared post, a different link, or any other method, the invite may not be credited to you.
How to make sure the invite counts
Send your invitation link
Share the invite link generated from your Friend Invitation screen
Your friend must use that link first
Your friend should tap your link and complete their first-time start flow directly from it
Check for your reward after they finish joining
Reopen the game and check your rewards again after your friend has completed their first entry.
