A casino is a gambling establishment where patrons can gamble on games of chance and sometimes skill. Slot machines, blackjack, roulette, craps, keno and baccarat generate billions of dollars in profits for casinos every year. A casino’s glitzy exterior and extravagant amenities such as musical shows, shopping centers and luxury hotels help draw in gamblers. But it is the games that keep them in business.
Something about gambling (probably the fact that large amounts of money are involved) encourages people to cheat and steal, either in collusion with each other or independently. For this reason, casinos spend a significant amount of their resources on security. Most modern casinos have video cameras in place to monitor game play and the surrounding area. Casinos also use bright and sometimes gaudy floor and wall coverings, especially red, to stimulate and cheer up players and make them lose track of time. Windows and clocks are rarely found in casino interiors, as they are believed to distract gamblers from calculating their losses.
Casinos employ a variety of other strategies to maximize revenue. Many have clubs that function like airline frequent-flyer programs, allowing patrons to accumulate points that can be redeemed for free or discounted food, drinks and show tickets. This system also allows casinos to build a database of patron information that can be used for marketing purposes.
In addition, casinos often reduce their house advantage on certain games to entice big bettors. For example, in France, where roulette is the principal casino game, houses typically reduce their edge to less than one percent. In America, where craps attracts the biggest bettors, most casinos reduce their edge to less than two percent.
Other casino profitability strategies include implementing games with low expected value and offering high payout percentages on those games. These methods are particularly effective for boosting revenue from slot machine play, where the house has a built-in profit margin of five cents to a dollar. Casinos also earn income from a levy on each bet placed, or rake, and a fee on winnings, or payback, which is the percentage of funds returned to players.
Although the casino industry is dominated by Las Vegas and Atlantic City, more than 30 states have legalized some form of gambling. Nevada’s reputation as the gambling capital of the world helps draw visitors from all over the country. Casinos provide jobs for more than 2 million Americans and contribute more than $24 billion to the economy annually. However, they also pose a number of social and economic problems. For example, some people become addicted to gambling and end up relying on casinos for financial support. Others lose their homes and families to gambling debts. Still others are forced to travel long distances from home in order to gamble, straining family relationships. In addition, casino gambling may harm local real estate values. Despite these negative effects, the popularity of casinos continues to grow. In 2008, about 24 percent of American adults had visited a casino in the previous year.
