A casino is an establishment for certain types of gambling. It may be located in or combined with hotels, restaurants, retail shops, and other tourist attractions. Some casinos are operated by governments, while others are owned and operated by private enterprises. In the United States, casinos are regulated by state law. Most states only allow licensed operators to offer a limited number of games, such as poker and blackjack. Some casinos are also known for hosting high-profile entertainment events, such as the Super Bowl or a pop music concert.

In the past, a casino was often referred to as a “gambling house”, and this is still the most common name for this type of business. However, the term has evolved to mean more than just a place where people can gamble. Increasingly, casinos are being used as family entertainment centers, where non-gambling activities can also be enjoyed. These include restaurant dining, shopping, nightlife, and live entertainment shows such as musicals and comedy acts.

Many modern casinos are designed to be attractive and comfortable for the guests, while also incorporating the latest technology to enhance the gaming experience. For example, some casinos use computerized systems to monitor betting chips with built-in microcircuitry; roulette wheels are electronically monitored to detect any statistical deviations from expected results; and the tables themselves are equipped with cameras that can be viewed by surveillance personnel from catwalks above the floor.

Casinos are often designed to appeal to a specific clientele, with architecture and interior design reflecting the themes of movies, music, or other popular culture. For instance, the opulent Caesars Palace casino in Las Vegas was inspired by the circus acts and ancient Roman architecture of its original location at the Circus Maximus showroom; it later became home to such renowned performers as Frank Sinatra and Celine Dion.

The large amounts of money that are handled within a casino can make it vulnerable to criminal activity. Both patrons and staff may be tempted to cheat or steal, either in collusion or independently. As a result, casinos take extensive security measures to deter crime and maintain order. These measures can include anything from security cameras to heavily armed guards.

In addition to security measures, most casinos also have policies in place to prevent players from exceeding predetermined loss limits. Most have self-exclusion programs that exclude problem gamblers from the premises for extended periods of time. These programs may include self-assessment tools, peer support groups, and other services.

According to the 2002 Gemini Research survey of Nevada citizens, the most popular casino games are slot machines and card games. In the United States, these include traditional table games such as blackjack and poker, as well as video poker. Other popular games at American casinos include keno and bingo, which each attract less than 10% of the gambling public. In Europe, baccarat and sic bo are the most popular table games, while in Asia, the most popular are pai gow and fan-tan.
