For now it looks like a scam. A similar website template can be found on Google. Do not make any deposits to this casino!
I also won a little from these free spins and bet on my withdrawal. I’ll write what happens next with the conclusion, but I have doubts. They may cancel the withdrawal and ask for a deposit.
I also found it weird that they would allow users withdraw money they won from free spins without any strings attached.
Usually when casinos give their users free spin when they free account it usually comes with high wagering requirements so that they won’t be able to meet the withdrawal criteria and then withdraw - in other words, the free spins will be a means for them to test the site without having to withdraw from it (since they’ll eventually lose their winnings before they meet the wagering threshold).
