Lol,,, that sounds cold! But it isn't far from the truth and it is what it is though. In this part of the world with regards to OP being African and I think OP takes residence in the continent too, Casinos are not very popular out here. There are sportsbookies everywhere you turn but, the case is different when it comes to Casinos. This could account for OP's ignorance on the term and formation but to have not seen a movie with a  vivid example of what a Casino is, that's extreme. Even the wild west movies futured some.
Well, we can't blame no one, through various means you get the education ad exposures you need and now, OP is surely getting one with the forum and on Casinos. Let's just hope OP doesn't get to gamble and waste all earnings before discovering the games and how to play.
