Arsenal, like all games on the Fabwelt ecosystem, offers a referral system. Basically, this means players can earn by bringing other players to Arsenal to further expand the userbase.
Every registered user in Arsenal has a personal referral code. You can give and publish this code anywhere in order to attract other players to sign up with your referral code. A player that signs up with a referral-code, gets a welcome bonus of 250 WELT!
When other players earn in Arsenal with your referral code, you will get 1% of their earnings as long as they play and earn!
