A referral system was put in place to encourage players to share the game with their friends. To access your referral link, you must access the Game settings (gear icon).
The referring player and the new player BOTH receive 5,000 GOLD + 5,000 ROCK + 5,000 WOOD in resources.
The new player must join Crypture World using your referral link. They must also adventure a few times to see the CLAIM BONUS popup. After the transaction is confirmed using their wallet, both players receive their bonus resources.
You can check the number of "confirmed" players you have referred in Game settings, the number is shown beside the title above your referral link.
After the 50th referral there is no bonus for the referring player. The new player who followed the link to join can still claim his bonus.
