A casino, also known as a gambling establishment, is a building or room where people can play various games of chance for money. Some casinos specialize in specific games, such as poker or craps, while others offer a wide variety of gaming options, including slot machines and blackjack. Casinos often feature elaborate, sometimes gaudy architecture and decor. The bright colors and lively music are designed to stimulate gamblers and increase their spending. The buildings may be adorned with statues, fountains, towers or replicas of famous landmarks. The gambling industry generates billions of dollars a year for the owners, investors and corporations that run them. State and local governments also reap benefits, such as taxes and fees.

In the United States, casinos can be found in many cities and towns, though they are most prominent in Nevada and New Jersey. They are also found in the Caribbean islands and on Native American reservations. In addition, casino-type game machines are found at racetracks and on riverboats and in some bars and restaurants.

Casinos must be regulated and licensed to operate legally. In order to maintain their license, they must pay millions of dollars in taxes and fees each year. In addition, they must adhere to strict rules regarding the use of security cameras and other surveillance equipment.

Because large amounts of money are handled within a casino, patrons and employees may be tempted to cheat or steal, either in collusion with each other or independently. To counteract this, casinos spend a great deal of money and effort on security measures.
