What Is a Casino?

A casino is a place where people can gamble with cash and/or paper tickets called chips. In a casino game, players place these chips on certain combinations of numbers that have been randomly generated. Casinos also host gambling games that require a degree of skill, such as blackjack and poker. The chips used in these games have built-in microcircuitry that interacts with electronic systems on the tables to allow casinos to monitor exactly how much is being wagered minute by minute and warn them if there is any anomaly. Several of these casino games have special rules to prevent cheating, including the requirement that players keep their cards visible at all times.

A modern casino may have two separate departments for security: a physical security force that patrols the premises and a specialized surveillance department that operates the closed circuit television (CCTV) system. These two departments often work together to prevent crime and are staffed by personnel trained to recognize suspicious or definite criminal activity. In addition, many casinos have hired gaming mathematicians and computer programmers to help them understand the mathematical underpinnings of their casino games and prevent cheating or rigging.

In addition to a range of casino games, many of these casinos feature five-star hotel accommodations, Michelin star restaurants, designer shops, and top-billed entertainment shows ranging from high-flying circus acts to the latest musicians topping the Billboard charts. In the United States, casinos are found in Las Vegas and Atlantic City, as well as on American Indian reservations where they can operate legally under state gambling statutes.
