A casino, also called a gaming house or a gambling establishment, is an institution where people can gamble and play games of chance. Casinos often combine entertainment and recreational activities such as restaurants, shops, live music and night clubs to create a complete experience for their patrons.
Despite their flamboyance, casinos are businesses that must make money. Consequently, they have built into every game a mathematical advantage that ensures that the house will always win the long-term, unless a player can eliminate it with skill. This advantage is known as the house edge, and it is a fundamental concept for anyone who plays a casino game.
While musical shows, lighted fountains and shopping centers are the major draws that bring in the crowds, casinos would not exist without the games of chance that generate billions of dollars in profits each year. Slot machines, roulette, craps, baccarat and card games like blackjack, trente et quarante and keno provide the income that pays for all the other bells and whistles.
Although the games of chance in a casino do not have any built-in elements of skill, some players are able to mitigate the inherent long-term disadvantage of the house by employing specialized techniques. These skills are often referred to as “advantage play” or “card counting.” Players who employ these strategies can reduce the house edge to almost zero, and they are sometimes compensated with free rooms, meals, show tickets and other gifts.
The casino industry was founded on organized crime, and mob money flowed into Reno and Las Vegas in the 1950s. However, legitimate real estate investors and hotel chains had far more cash than the gangsters, and they were quick to realize the potential of casinos as destination resorts for tourists. As federal crackdowns on mobsters began to take hold, many mobster-owned casinos were sold or merged into legitimate operations.
Today, casino gambling is legal in 40 states and is a multibillion-dollar industry. While the popularity of casinos has increased dramatically, there is still considerable controversy over how casinos should be regulated and what impact they have on local economies. For example, some people argue that casinos encourage problem gambling and are harmful to the economy because they divert resources from more productive uses. Others support them because they provide jobs and tax revenue. In any event, the casinos have become a dominant force in American culture and continue to grow. This article examines the history of casinos, their evolution and growth, and the impact they have on society.
