Not complicated at all, heard about commissions? That's it, all you have to do is to promote your link and encourage someone to sign under your link and if they deposited some money there, you'd get the % from that money and that will be your commission or you call the affiliate money that you earn. It's no brainer at all but to have as much referrals or affiliates is a hard task so those that have been into this kind of business are into volumes and quantity of the affiliates and commissions that they're getting. If they are serious with it, they're making more than the minimum wage if they've got a lot of referrals and the majority of them are active gamblers that keeps on depositing money time after time. But a situation is when they're on the good season now but after a few days, weeks or months they won't be.
