It is not a secret, but this is russian casino with KYC. If anyone interesting - winline, promo code - UFF5000, but i don`t know if it still working. Decide by yourself to boycott russian casinos or to get bonus.
I have no problem with Russian casinos but not for KYC on any casino platform, but the promo bonuses offered seem real because users can use withdrawals but unlike many other casino platforms it can only be used to bet on the casino. Can you provide details of the casino you mean because I will do a test for the use of promo codes.
I wouldn't get interested to it since first they do ask KYC which most of us doesn't like. Do all gambling site do have sign up bonuses? it's very rare nowadays to look for a gambling site that doesn't offer sign up bonuses since most of them do have this bonus.
