Oh, perfect timing! I actually sent the link to my brother yesterday. The system is pretty transparent. You go into the menu, copy your unique URL, and send it via messenger. The best part is that you can simply Invite friends & earn, because you instantly get 10,000 GC and 1 SC for each of your first six friends. Your friends also get their own sign-up bonuses. If they later decide to buy a coin package, you receive an extra reward of 15% of their purchase. The fixed payout limit applies to the first six invites, but percentage-based rewards from purchases continue more broadly. Do your colleagues enjoy casual games like this, or are they more into strategy games?
