The Coupon code activation process goes as follows: The inviter sends a message to the invitee with a four-digit code. The invitee can enter the code in two different screens:

1. The "Log in" screen after completing the introductory island.

2. Or after you logged in, you can also activate the Code in the Shop by tapping on ’Enter Coupon code.

If the invitee wishes to enter the received Coupon code in the Shop, they need to do so WITHIN 72 HOURS after their registration for the system to accept the invitee as a new user. Once the invitee activated the Coupon code, they will be NOTIFIED immediately and the bonus Xeropan coins will be credited to their accounts. It generally takes AN HOUR for our system to process the activation for the inviter and only then will the bonus Coins be credited to their accounts as well.

If you experience any issues, make sure the invitee has entered their Coupon code within 72 hours after their registration.
