What Is a Casino?


A casino is an establishment for certain types of gambling. Typically, it is combined with hotels, restaurants, shopping centers and/or other entertainment venues. Some casinos offer a wide range of gaming activities, including slot machines, table games, keno, craps, and roulette. Many casinos also offer a variety of live entertainment acts and/or sports events.

Casinos are operated by governments or private organizations and are regulated by laws governing gambling. Most countries have legalized some form of casino gambling. In the United States, most casino activity takes place in Nevada and Atlantic City. In addition, some Native American tribes operate casinos.

Most modern casinos use sophisticated technology to control the gambling process and protect patrons. For example, chips with built-in microcircuitry enable the casino to monitor the exact amounts wagered minute-by-minute and warn them of any anomaly; a computerized system constantly monitors the results of roulette wheels to discover statistical deviations quickly; and a network of cameras gives casino security personnel a virtual eye-in-the-sky that can be adjusted to focus on suspicious patrons.

Free food and drink helps keep gamblers on the premises longer, but it does not reduce the house edge. In addition, casino designers employ a number of subtle tricks to deter cheating. Windows and clocks are rarely visible in casino interiors, for example, to prevent players from noticing how much time they’re spending on the games; and the absence of chiming clocks makes it easier for people to lose track of how long they’ve been gambling.
