Casino, or gambling house, is an establishment where people can gamble and play games of chance. Casinos can be large hotel and entertainment complexes or small card rooms in bars, restaurants, and even truck stops. In the United States, casinos are regulated by state and local laws and are often operated by Indian tribes on reservation land. The profits from casino gambling bring in billions of dollars each year for the businesses, investors, and workers involved. However, because of the large amounts of money handled, both patrons and employees may be tempted to cheat or steal. As a result, casinos employ a variety of security measures. These include cameras, security personnel, and rules governing behavior.
Although casinos offer many other amenities besides gambling, such as musical shows and elaborate themes, they would not exist without the revenue from games of chance. Slot machines, blackjack, roulette, craps and keno are just some of the games that attract people to casinos and generate the billions in profits that casinos rake in every year.
Some states, including Nevada and New Jersey, prohibit the advertising of casinos, but casinos can be found throughout the country, especially in areas popular with tourists. In addition to those in Las Vegas and Atlantic City, some are located on American Indian reservations, while others are on riverboats or operate on barges that travel between various cities and towns. Some casinos are also located within racetracks and are called racinos.
