I remember a scene in 21 wherein the actor was tested under pressure and so he was advise to go to a underground place and played and then they put a sack on his head and test him if he can still remember his card count. Perhaps that's what the atmosphere on some of those underground casinos.
It’s definitely a different atmosphere and one thing for sure is not regulated.
But we are not sure if that is true or not, maybe the representation is wrong and they just added something to make it dramatic.
What’s interesting about underground casinos is that you can dress however you want, and as long as you have money, you’re welcome. If you bet big, you're treated like a VIP - no questions asked. And who hasn’t seen the movie 21, right? That was such a good film all about card counting. I believe it still happens today, but with advanced cameras and tech, patterns of winning can be tracked, and in the long run, you might get exposed.
That is also the same with landbase casinos, as far as I know there is no dress code there, at least look decent, smells good, no flipflops or open shoes then you are all good. Even if you bet big you are not going to be treated as VIP as there is a separated room for VIP in a casinos, just to let you know.
That’s why doing it in an underground casino is super risky.. you never know, you could end up in serious trouble… or worse...
I do agree, you really don't know what's inside, and who knows, maybe the first time you go there, there might be operations and you might be caught by the police. So there is a big risk and for some of us, we don't like to take that.
