From my experience with casinos, I would stay away from this one. I took a rough look at the site and there a some factors that indicate that it is a scam site. There is no official address of the location, usually such casinos have at least a address in Malta, Gibraltar or the Bermuda Islands where they also got their license from to operate legally. Also as @dec2020mcl already wrote, they are operating under the 1668/JAZ licence what is the next indicator. So better stay away!
