A casino, also known as a gambling hall or a gaming room, is a place where people play a variety of games of chance. While the modern casino often adds luxuries like restaurants, musical shows and shopping centers to draw in customers, it would not exist without games of chance that provide the billions of dollars in profits casinos take in each year. Slot machines, blackjack, roulette, baccarat and other games of chance are the mainstays that help casino owners rake in the dough.
Something about gambling (probably the presence of large amounts of money) encourages people to cheat, steal or scam to try to win, and that’s why casinos spend a lot of time and effort on security measures. In addition to the usual cameras everywhere, casinos use specially trained staff and sophisticated technology to monitor game results and players. Security officers watch tables from a centralized control room where they can quickly spot any suspicious behavior. Table managers and pit bosses have a broader view of the tables, watching patrons as they play and looking for betting patterns that indicate cheating or collusion.
The games themselves are monitored as well, with special chips that contain microcircuitry that allow the casinos to oversee the exact amount of money wagered on each bet minute by minute; roulette wheels are electronically monitored to discover any statistical deviations from their expected results; and video cameras can be aimed at specific patrons or tables at the push of a button by security personnel in a room filled with banks of computer screens. While the high-tech surveillance may not prevent everyone from trying to bend the rules a bit, it does make cheating far less common than it might be in a more casual atmosphere.
Casinos make money by charging for admission and then collecting a percentage of the bets placed on games. This is called the vig or rake. While this doesn’t always bring in a profit, the overall house edge ensures that the casino will eventually come out ahead. In the long run, it’s very rare for a casino to lose money on its games. To offset the house edge, casino offer free food and drink, hotel rooms, and extravagant inducements to big bettors in the form of free spectacular entertainment and reduced-fare transportation.
