How does inviting friends work?
Share your invitation link from the Coins page. A friend counts once they have predicted 3 different matches that have kicked off. You earn 10 coins for each of your first 5 friends, 20 for friends 6 to 15, 30 for friends 16 to 30, and 40 after that. The reward is taken back if the friend deletes their account within 30 days.
