What Is a Casino?
A casino is a gambling establishment where customers place bets on games of chance or skill. Most casinos feature a variety of table games, slot machines and video poker. They also offer a variety of other betting activities such as keno and craps. Casinos are most often located in places with legal gambling opportunities, such as Nevada and Atlantic City, New Jersey, but are increasingly being opened in other states as well. Despite their glamorous images in films and on television, casinos are not for everyone. They can be addictive and financially disastrous for many people.
Casinos are largely built on the concept of maximizing profits through volume rather than profitability per customer. They have to cover overhead expenses such as the cost of staff, security and maintenance of gaming equipment and space. In addition, they must pay out winnings to players after a certain percentage of money is deducted for taxes and the house edge. Some casinos also take a cut of winnings, a fee known as the vigorish or rake.
Gambling almost certainly predates written history, with primitive protodice and carved six-sided dice found in ancient archaeological sites. However, the modern casino as an entertainment center with a wide range of gambling options did not develop until the 16th century, when a gambling craze spread to Europe. Italian aristocrats frequently held private parties at their homes, called ridotti, where they could gamble legally without fear of persecution by the Inquisition.
The modern casino is designed with security in mind. Surveillance cameras constantly monitor the casino floor, and a team of high-ranking managers reviews all security footage. Casino employees are trained to look for blatant cheating, such as palming or marking cards or switching dice, and they are especially attentive to patterns that indicate players may be trying to predict the outcome of a game.
During the 1990s, casinos dramatically increased their use of technology to supervise games. In some cases, the machines are equipped with chips that have built-in microcircuitry to monitor bets minute by minute; in other cases, such as roulette, automated computers regularly monitor the wheels for any statistical deviation from their expected results. Casinos also use catwalks suspended above the games that allow surveillance personnel to see directly down, through one-way glass, on the activities of players at the tables and slot machines.
The casino industry is notoriously lucrative for organized crime figures. Mobster money flowed steadily into Reno and Las Vegas in the 1950s, and some mobsters became personally involved, taking sole or partial ownership of casinos or even intimidating casino personnel to manipulate game outcomes. This taint contributed to casinos’ seamy image and helped give rise to the term “Casino Mafia.” The mafia’s involvement in casinos eventually faded as other sources of revenue became available, including the advent of legalized sports gambling and the growth of interstate travel. Today, the majority of casinos are run by legitimate businesses, although organized crime still has a presence in some areas.
