To be honest I do not check if the casino has a license or not. What I do before I step into a casino is that I do a little research and check their reviews, and if they have a good reputation. When I'm intrigued and wanna find out more about a casino, I then check out how's their customer service, if it's good or nah. Or what I do is deposit a small amount to check if they have a good or fast deposit and withdrawal. If they are good and meet what I'm looking for in a casino, I slowly increase my bets (but not so much or high), and so far, I have not encountered a problem even though I'm not sure if they have a license or not.
