A casino is a place that allows patrons to gamble. It usually has gaming tables (such as blackjack, roulette, and poker), and slot machines, as well as other entertainment options like restaurants, bars, and stage shows. Casinos may also offer sports betting on major events. Some of the more luxurious casinos include hotels, spas, and even top-tier restaurants.
Gambling almost certainly predates recorded history, with primitive protodice and carved knuckle bones found in cavemen’s dwellings [source: Poley]. However, the modern concept of a casino as a central facility for gambling did not emerge until the 16th century, during a gaming craze in Europe. At that time, Italian nobles often hosted private gambling parties called ridotti in their homes (source: Schwartz).
While many people associate casinos with Las Vegas and other major cities in the United States, they are increasingly appearing on Native American reservations and on cruise ships. In the 1980s and ’90s, some states amended their antigambling laws to allow casinos on riverboats and in land-based locations.
Casinos focus on customer service and use a variety of methods to ensure security. For example, they use cameras to monitor the games and patrons. They also enforce rules of conduct and behavior, such as requiring players to keep their gambling cards visible at all times. Many casinos also have “comps” programs, which reward high-volume patrons with free or discounted food, drinks, hotel rooms, and show tickets. Casinos use their comps to encourage high-volume gambling and to develop a database of regular patrons that can be used for marketing purposes.
