How come having two or more account help to win more ? More accounts = more to deposit = more to lose, when chance to win is the same for every gambler. I can only understand if the situation was about users trying to cheat with welcome bonuses if there were any. But correct me if I am wrong, nobody now gives free bets or free spins just for a registration. I could understand if a person creates another account, because his first was banned, but it is a risky move, because chances for second account to be banned are increased. I can accept that someone create multiple accounts because he wants to get low level up bonuses, because wagering several thousands is always easy than, for example, wager from 50k to 100k to get free 10$. But that is also illogical. While trying to get $10, it easy to lose much more.
As @ultrloa, @Adbitco, and @Hirose UK said, having multiple accounts can benefit gamblers especially in referral. They can get more amount as the reward if they use all of their account in different time. But casino will know and will investigate it furthermore to proves that they are not cheat the casino. They will use one account and playing gambling and they don't mind to deposit more money because they have a reason why they use multiple accounts. We never know what is their reason because those people will not telling clearly the goals. For us, that will not make sense but for them, that still make sense especially if they are often doing that in the other casinos. We just don't know how and what they will do.
Can you explain how gambling referral reward system works then? Because as I know, you get something from casino only when a referral looses money. What is the trick then, when I have to lose my own money to get a only a % of them back. If casinos pay when a referral makes a deposit, then depositing/withdrawing method would created owner of a referral rich. But casinos aint stupid. I can assume, the same casinos have levelling system, where you not only have to wager a specific amount, but brings several referrals as well (stupid system imho). In that case I can understand why a person creates several more accounts. But again, he creates them only to unlock a next level, he did not gamble from those second or more accounts.
