What Is a Casino?


A casino is a gambling establishment that offers a wide variety of games of chance. These games can be played on table, such as poker, baccarat and roulette, or by using slot machines. Most of these games are based on luck, but some have an element of skill. In addition to the games of chance, casinos also offer food and drinks. Some casinos also have entertainment, such as musical shows or lighted fountains.

There are over 1,000 casinos in the United States. The largest concentration of casinos is in Las Vegas, Nevada. Other major gaming centers include Atlantic City, New Jersey and Chicago, Illinois. Most of the casinos in the United States are owned by private businesses. Large real estate developers and hotel chains have purchased many casinos, and some are even owned by celebrities or investment banks. These companies have a vested interest in keeping mobsters away from their gambling establishments, since they can lose their casino licenses at the slightest hint of mob involvement.

Although gambling in one form or another probably predates recorded history, the modern casino as we know it was first developed in the 16th century. The Italian aristocracy at the time was very fond of gambling, and they would gather at places called ridotti to gamble and enjoy themselves. Although technically illegal, the aristocrats were rarely bothered by law enforcement.

Casinos have become a major source of revenue for many cities, and they are often the center of attention in television and movies. Some of the larger ones feature multiple floors, thousands of slot machines and several hundred tables. They also have elaborate decor, including lighted fountains and replicas of famous landmarks. They are also renowned for their security measures. Despite their high profile, the casinos are not immune to crime and violence.

Many of the games of chance offered in casinos have a built in statistical advantage for the house. This advantage can be very small, less than two percent, but it adds up over the millions of bets placed each year by patrons. The house edge is what gives the casino its profitability. It is a key part of why casinos must continually spend on security, and it is why so many have strict rules about who can and cannot enter their premises.

In addition to the basic security measures, casinos use advanced technology to monitor and control their gaming operations. Video cameras are used for general surveillance, and sophisticated systems of “chip tracking” allow the casinos to supervise the exact amount of money being wagered minute by minute. Roulette wheels are monitored electronically to discover any statistical deviations from their expected values, and some games have been entirely automated in the name of increased efficiency and reduced costs. Something about gambling (probably the presence of large amounts of money) seems to encourage cheating and theft, which is why casinos must constantly invest in security. In addition to their staff, casinos hire security guards to patrol the premises and keep an eye out for potential problems.
