A casino is an establishment for certain types of gambling. Casinos are often combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. Some casinos are famous for their architecture or location, and some are known for hosting live entertainment. Most casinos are located in Las Vegas, Nevada; however, they can also be found in many other cities and countries throughout the world.

A modern casino features a wide variety of games of chance, some of which involve skill, as well as video poker and electronic slot machines. The most common casino games are blackjack, roulette, baccarat, and craps. These games have mathematically determined odds that give the house a constant advantage over players, and this edge is commonly known as the “house edge”. In addition to these games, some casinos feature poker tables where patrons compete against each other and the casino makes a profit by taking a percentage of the pot or charging an hourly fee to play.

Because of the large amounts of money that are handled within a casino, both patrons and employees may be tempted to cheat or steal, either in collusion with each other or independently; for this reason, most casinos feature security measures such as closed circuit television. In the United States, the casino industry is regulated by state gaming commissions, with Nevada having the most prominent gambling market in the country. In the 1980s, casinos began appearing on American Indian reservations, which were exempt from state antigambling laws.
