A casino, also known as a gambling house or a gaming hall, is an establishment for certain types of gambling. It features games of chance, such as slot machines, blackjack, roulette, craps, baccarat and poker. Casinos are often combined with hotels, restaurants and other tourist attractions. Some casinos specialize in particular kinds of games, while others offer a variety. Many people are familiar with the large casinos in Las Vegas and Atlantic City. However, there are many more casinos throughout the United States.

The casinos earn billions of dollars annually by allowing patrons to gamble for money or other goods and services. The games are regulated by government laws and regulations. In addition, the gambling houses must be licensed to operate in each jurisdiction. The license is based on the number of machines, table games and other gaming activities permitted in the jurisdiction.

While the games of chance are the main source of income for the casinos, they also feature entertainment, such as musical shows and lighted fountains, as well as shopping centers and other amenities. The casinos are usually located in a beautiful location and are highly themed, making them popular with tourists.

Because of the large amount of money handled in casinos, security is a major concern. In addition to a physical security force, there are electronic security measures. For example, chip tracking systems allow casinos to monitor how much money is wagered minute-by-minute; and the roulette wheels are electronically monitored to detect any statistical deviation from their expected outcome.
