A casino is a gambling establishment that offers a variety of games of chance. These include slot machines, blackjack, craps, roulette, baccarat and poker. Some casinos also offer entertainment and other amenities. These establishments are usually crowded with people, and they are often surrounded by flashing lights and glamour.
Historically, casinos have been the playgrounds of organized crime figures. They were sometimes run by mobsters and mafia families, who found that they provided an excellent source of income and prestige. They also drew in people from all over the country and world who came to spend their money.
Today, casinos rely heavily on technology for both security and to oversee the games themselves. For instance, betting chips have built-in microcircuitry that communicates with electronic systems at the tables to allow casinos to see the exact amounts wagered minute by minute and alert them to any statistical deviation; roulette wheels are electronically monitored to discover any tampering. And cameras in the ceiling can be directed at suspicious patrons by security workers in a room filled with banks of monitors.
In the twenty-first century, a few major casino companies control much of the industry, and they concentrate on attracting high rollers—gamblers who spend more than average. They are often given luxury suites, personal attention and other perks. The typical casino gambler is a forty-six-year-old woman from a household with an above-average income, according to studies by Roper Reports GfK NOP and the U.S. Gaming Panel by TNS.
