What Is a Casino?


A casino, also known as a gaming house or gambling establishment, is an establishment where people can play games of chance. These games often have a social component, and the casinos are designed to encourage patrons to interact with one another. In addition to gambling, casinos may offer restaurants and bars, entertainment events, and other amenities. In the United States, the largest concentration of casino gambling is in Las Vegas. Other significant locations include Atlantic City, New Jersey, and some American Indian reservations.

The casinos make money by combining the elements of chance with some element of skill, such as in blackjack or poker. Every game has a built in statistical advantage for the casino, which can be very small (lower than two percent), but over time and millions of bets it adds up. The advantage is a casino’s profit, and it is earned by collecting a percentage of all bets made, referred to as the vig or rake. Casinos spend huge amounts of money to protect their profits, and security is a top priority.

Most modern casinos have elaborate security systems that employ a variety of technologies. For example, video cameras monitor all entrances and exits to ensure no one is stealing. Chip tracking enables casinos to oversee bets minute by minute, and electronic devices in table games detect and alert the pit boss or manager when a problem occurs. Roulette wheels are monitored electronically to discover any statistical deviation from expected results.

In addition to protecting their profits, casino owners are concerned about the reputation of their businesses. Many casinos strive to have a “sexy” image, and use glitzy architecture and d├ęcor to attract attention and bring in customers. Casinos often sponsor or host high-profile events, such as boxing matches and concerts, to generate publicity.

Gambling can be addictive, and the casinos work hard to promote responsible gaming programs. They also provide help to those in need, and have policies for dealing with compulsive gamblers. In some jurisdictions, the casinos are required to report information about their customers to government agencies.

In the early days of gambling, organized crime figures controlled most of the operations in Reno and Las Vegas. They had the money from drug dealing and extortion, and didn’t mind the seamy reputation of gambling. However, the mob’s influence waned as legitimate businessmen with deeper pockets realized how much they could make. They bought out the mobsters, and casino gambling became a regulated industry. In the 1980s, the first legal casinos opened on Native American reservations in the United States, and more began appearing internationally. Today, there are more than 3,000 casinos in operation worldwide. Some are associated with hotels, resorts, or other leisure facilities; others stand alone. Most of the world’s casinos are located in cities with a large population of tourists. However, there are a number of smaller casinos in remote locations. Some are even open 24 hours. In some cases, the casinos are designed as tourist attractions, with displays of exotic animals and plants or replicas of famous buildings.
