A casino, or gaming house, is an establishment for certain types of gambling. These casinos are often built near or combined with hotels, restaurants, retail shops, and other tourist attractions. In some countries, casinos are licensed and regulated by government agencies. The term is also used for casinos on riverboats and on American Indian reservations.
In addition to slot machines, most modern casinos feature table games such as blackjack and roulette. Some of these table games are played against the casino; others are conducted against other players, such as in poker. A dealer, or croupier, deals the cards and runs the game. Casinos also offer a variety of other gambling products, such as lotteries and sports betting.
Unlike most other forms of gambling, casino gambling is social in nature. In addition to table and card games, many casino patrons participate in a wide range of other activities such as watching a show or listening to live music. Alcoholic drinks are available at many casinos, and some offer snack food as well. Casinos are usually open to the public and provide free parking, although some limit access to patrons who are hotel guests.
In 2008, the average American spent nearly $52 in a casino. In order to attract players, most casinos use a system of comps (complimentary). These programs give players cards that can be swiped before each play to track their spending and activity; the cards are then exchanged for free slot play or vouchers for meals, drinks, shows, and other nongambling activities. The most popular casino games in the United States are blackjack, craps, and poker.
