A casino is a gambling establishment where people can play games of chance for money. These games include slots, blackjack, craps, roulette, baccarat, poker, and other card games. Some casinos also have video poker machines. Some have a combination of these games and other entertainment. Casinos are located in many countries and are often a big part of the local economy.
Security in a casino starts on the gaming floor, where employees keep an eye on patrons and the games. Dealers are heavily trained to watch for blatant cheating such as palming, marking or switching cards or dice. They also follow a set of routines, such as when they shuffle and deal the cards. Pit bosses and table managers have a broader view of the tables, watching for betting patterns that might indicate cheating or collusion between players.
Something about gambling attracts criminal elements, and it is not uncommon for casinos to have a problem with organized crime. Mobster involvement is a serious concern for some casinos, especially in Las Vegas. However, the deep pockets of real estate investors and hotel chains have made it possible to buy out mafia ties to the point where the mafia now largely stays away from casinos.
There are a lot of different casino games, some more popular than others. Slots are by far the most popular, but you will find a variety of other games at most casinos. Some casinos even have a special section for table games.
