A casino is a place where people gamble by playing games of chance or, in some cases, skill. Generally speaking, casinos make money by charging players an entrance fee (generally referred to as a “vig”) or by taking a commission on certain types of bets, such as those in poker.

While a casino can be an excellent source of entertainment, it is important to understand how these establishments operate in order to avoid becoming addicted or gambling irresponsibly. In this article, we’ll take a look at some of the basics of casino operations and how they work to keep the house in the black.

Casinos have long been a fascination for the public, inspiring such movies as Ocean’s 11, and even non-gamblers are intrigued by the flashing lights, the five star food and the spectacle of millions of dollars changing hands on a daily basis. The precise origins of gambling are difficult to pinpoint, but it is thought that humans have been using games of chance to entertain themselves for millennia.

With such a large amount of money handled within a casino, there is always the possibility that employees or patrons will cheat or steal. To combat this, most casinos have security measures in place. On the floor, this starts with dealers who are trained to spot blatant cheating like palming or marking cards. In addition, each table has a pit boss who oversees the table. This supervisor keeps track of each person’s bets and can spot betting patterns that could indicate cheating.
