What Is a Casino?


A casino is a gambling establishment, typically combined with restaurants, hotels, and/or other tourist attractions. It is known for entertaining patrons with a wide variety of gambling opportunities and events, including poker, blackjack, slots, roulette, and craps. The precise origin of gambling is unknown, but it has been popular throughout history in almost every culture.

Modern casinos resemble indoor amusement parks for adults, with much of the entertainment (and profits) derived from games of chance. Slot machines, video poker, keno, and other games of chance earn casinos billions in profits each year. Musical shows, lighted fountains and shopping centers add to the attraction, but gambling makes up only a fraction of a casino’s allure.

In the United States, casinos are generally licensed to accept bets on certain types of sports and events. In some cases, the licenses are issued by state governments. The casino industry is regulated in many jurisdictions, and operators are required to pay taxes on their earnings. Casinos often use their profits to offer free spectacular entertainment and transportation to big bettors.

Most casinos employ strict security measures to protect their patrons and their assets. Surveillance cameras monitor the gaming floor, and employees look out for blatant cheating such as palming or marking cards. Table managers and pit bosses watch the games with a broader perspective, observing betting patterns and other suspicious behavior. Several technological innovations have made casino security even more rigorous. For example, some casinos use chips with microcircuitry that interacts with electronic systems to oversee the amount of money wagered minute by minute, and roulette wheels are electronically monitored for any statistical deviation.
