What Is a Casino?


A casino is a large building or room in which gambling games are played. It also has dining and entertainment options. The name is derived from the Latin casino, meaning “house of games.” Casinos are legal in most jurisdictions as long as they do not violate gambling laws.

A number of different gambling games are played in casinos, including blackjack, roulette, and poker. Some casinos offer a wide range of other games as well, such as baccarat, sic bo, and fan-tan. In addition, many casinos have floor shows and other forms of entertainment for those who are not interested in gambling.

Many casinos use advanced technology to monitor their games and customers. For example, in some games, betting chips have built-in microcircuitry that enables the casino to monitor the exact amount wagered minute by minute and warn them of any statistical deviations from expected results; and in some casinos, the wheels of roulette and dice are electronically monitored regularly to discover and correct any anomalies. This type of work is performed by people who are called gaming mathematicians or analysts.

While most casinos do not employ a full-time staff of such professionals, many hire consultants to perform this work for them. In addition, the computer programs that generate the house edge and variance information used by casinos are usually the work of experts in the field of mathematical statistics. These experts are usually employed by consulting firms that sell or license the software to casinos.
