Some casinos will give you back good % of your net losses every week, but only if you keep playing for their tiered VIP system. Does the rebate really make us take smarter risks, or does it trick us into going after losses we would normally just walk away from?
It has been statistically proven that if a person stays longer exposed in any kind of gambling influence, the more chances that he/she would loss given the presence of house edge in favor of casinos.
OP you mentioned that there are certain casinos that will offer a rebate depending on the percentage of your losses every week. This may definitely sound appealing to your average gambler because it somehow gives you a sense of security for your losses. But this kind of scheme makes you want to gamble more in the process, which thereby exposes you to more risks in the future.
While I do agree that some casinos do not offer this kind of privilege to their VIP users, still in my humble opinion, this will trap the player into gambling more in the process. Ultimately, the casino will benefit long-term from this method.
