What Is a Casino?

When most Americans think of a casino, they envision the flashy megaresorts that dominate the Las Vegas Strip. But the term is actually a broader one. Merriam Webster defines it as a building or room used for social amusements, particularly gambling.

In general, casino gamblers make money by betting on games of chance and in some cases with an element of skill. These include craps, roulette, baccarat and blackjack. Most games have mathematically determined odds that ensure the house has at all times an advantage over the players, which is called the house edge. The house makes a profit by taking a percentage of each bet, which is known as the vig or rake. In games like poker where patrons play against each other, the house may take a cut of the pot or charge an hourly fee to rent tables.

Casinos also focus on customer service and provide perks designed to encourage patrons to spend more. These are called “comps,” and they can include free drinks, stage shows and luxurious living quarters. They also offer discounts on hotel rooms and show tickets. In the 1970s, Las Vegas casinos were famous for their extravagant inducements to big bettors.

Although casinos may have positive economic effects, critics point out that they divert local business from other entertainment options and that the expense of treating problem gambling often offsets any gains. Some economists also argue that the social costs of casinos, including crime and lost productivity, far outweigh any revenue they generate.
