A casino, also called a gambling house, is an establishment where people can gamble for money on games of chance or skill. Most casinos offer a variety of gaming options, such as blackjack, poker, craps, and roulette. Some casinos also have live entertainment and serve food and drinks. In addition, some have hotel accommodations. Casinos are usually located in cities with large populations and are often built near or combined with hotels, retail shops, restaurants, and nightclubs.
Casinos are designed around noise, light, and excitement, and patrons often interact with other gamblers or shout encouragement to fellow players. Alcoholic drinks are frequently served to players at table games, and nonalcoholic beverages are available for free. In the United States, casinos began appearing in Atlantic City and on American Indian reservations after 1978, and many states amended their antigambling laws in the 1980s to permit casinos. In the 1990s, a number of Native American casinos opened.
Although gambling almost certainly predates recorded history, the modern casino as a place for people to find a variety of ways to gamble under one roof did not develop until the 16th century, when a European gambling craze swept the country and Italian aristocrats opened private gambling clubs known as ridotti [Source: Schwartz]. Casino as a word entered English in the 18th century, but it was in Europe that the first major casino opened, at Monte Carlo, Monaco, in 1863.
Casinos make their profits through the “house edge,” a built-in advantage that guarantees them a certain amount of gross profit from each player’s bet, regardless of the specific game or the number of rounds played. Because of this virtual guarantee of profits, the casino can afford to offer big bettors extravagant inducements, such as free spectacular entertainment and transportation, reduced-fare hotel rooms, and meals, beverages, and cigarettes while gambling.
