I got $50 sign up bonus with promo code, withdraw was inactive. I made 2 bets, $20 and $30, i couldn`t choose the bet size. After 1 win, withdraw button became active, i withdraw $20 for test.
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.
Is this the link to the casino you are talking about: winline.ru ?
I googled "winline casino" but didn't get any result so I assumed it's an
ru TLD since you said it's a russian casino!
Regarding their kyc policy, do they enforce it on all players on registration or only when you make a withdrawal request?
Also, could you, pls, confirm that you withdrew the bonus winnings without making any deposit? Because there aren't many casinos that offer a no-deposit bonus with only a 1x wagering requirement.
