What is a Casino?

A casino is a place where people can gamble on various games of chance and in some cases skill. While lavish hotels, musical shows, lighted fountains and shopping centers help attract customers, casinos would not exist without games of chance that offer billions in profits every year to gambling operators. Slot machines, blackjack, roulette, craps, keno and baccarat are among the most popular casino games.

The earliest casinos were mob run affairs, but real estate investors and hotel chains with deep pockets bought out the mobsters. Federal crackdowns and the threat of losing a gaming license at even the slightest hint of mob involvement keep the mafia out of most modern casinos.

In addition to offering a variety of gambling opportunities, most casinos also offer food, drinks and entertainment. Some are known for their opulence and dramatic scenery, such as the Bellagio in Las Vegas; others are famous for their architecture or for hosting high-profile events like the World Series of Poker.

Most games of chance in casinos have a built-in house advantage that ensures the casino will always win money over the players, regardless of the actual odds of each game. This advantage can be lower than two percent, but it adds up over millions of bets and is the main source of revenue for the casinos. The casino may make additional profit in games such as poker, where the patrons play against each other, by taking a small percentage of each pot or charging an hourly fee to players. The casino may also give out complimentary items or comps to its best players, such as free hotel rooms, show tickets and limo service.
