A casino, also known as a gaming establishment or simply a gambling house, is a building or room where people can play various games of chance for money. The term is most associated with Nevada, where many of the world’s first legal casinos opened. But in the United States there are many more places to gamble, and the number is growing as states legalize casinos.

Unlike many other forms of entertainment that are more abstract or isolated, casino gambling is socially oriented. Players are often surrounded by other people as they play a game of chance or poker, and the atmosphere is designed to be loud and exciting. There are typically waiters circulating throughout the casino to offer drinks, and there is often a stage for theatrical performances.

Casinos are businesses and, like any business, they need to make a profit. They accomplish this by offering a variety of perks and amenities to attract customers and by taking advantage of the natural human tendency to want to win. They use mathematically determined odds to ensure that the house will always win, and this advantage is referred to as the house edge.

Because of the large amounts of money handled within a casino, patrons and staff may be tempted to cheat or steal, either in collusion or independently. To prevent this, casinos employ a number of security measures. These include security cameras located throughout the casino, a system called chip tracking that allows each betting chip to be tracked minute by minute, and roulette wheels that are electronically monitored for any statistical deviation from their expected results. In addition, the routines of casino games, such as how cards are dealt and shuffled, and the locations of betting spots on the table, follow predictable patterns, so that it is easier for security personnel to spot any unusual activity.

Because of the high concentration of casinos in Nevada, Las Vegas is often regarded as the center of casino gambling in the United States. However, other cities and states have developed significant gaming industries, including Atlantic City, New Jersey; Chicago; and Iowa. Many of these cities have casinos that are as large or larger than those in Nevada. There are also a large number of Native American casinos.
