A casino is a place where people gamble on games of chance. Modern casinos add many other entertainment features, such as restaurants, musical shows, lighted fountains, shopping centers and luxurious hotels, but the vast majority of the revenues come from gambling. Slot machines, blackjack, roulette, craps, baccarat and other games provide the billions of dollars in profits that casinos bring in each year.
While the luxuries and distractions of casinos help draw in customers, they would not exist without the games of chance. Despite the fact that most casino games have an element of skill, the house always has a mathematical advantage over players. This advantage can be very small – less than two percent in some cases – but it adds up over millions of bets and earns the casino enough money to build elaborate hotels, fountains and replicas of famous landmarks. Casinos also make money from a percentage of the money played on games such as poker and video poker, which are not based on luck but rather on strategic play.
Gambling was illegal for most of American history, but this did not stop organized crime figures from raising large sums of money to fund casino games in Reno and Las Vegas. Mob money helped these casinos grow and become a major economic force in Nevada, but federal crackdowns and the taint of criminality kept them from spreading to other states. Real estate investors and hotel chains with deep pockets were able to buy out the mobsters, and they now run many of the nation’s largest casinos.
