A casino is a gambling establishment where players place wagers on games of chance for money or other prizes. A casino’s reputation for fair play and responsible business practices is an important part of its brand, and it must be guarded at all costs. Casinos are regulated by governments around the world, and some have strict rules regarding who can play. Those who are underage or have financial problems may be barred from entering casinos.
The modern casino is like an indoor amusement park for adults. While musical shows, lighted fountains and shopping centers help draw in the crowds, it’s the games of chance that provide most of the profits to the owners. Slot machines, blackjack, roulette, craps and keno generate the billions in revenue that make casinos one of the most lucrative businesses in the world.
Casinos have become a major tourist attraction in their own right, with some claiming more visitors than the Eiffel Tower or Las Vegas Strip. Many cities have built permanent casinos, and Native American tribes have also opened their own facilities. Gambling in some form or another has been popular throughout history, with the earliest known examples dating back to ancient Mesopotamia and Egypt. Modern technology has increased the popularity of casino games, as well as the number of players who participate.
While the glitz, glamour and high stakes of casino gambling are enough to attract people from around the world, there’s a darker side to the business. Almost every casino game has a built in advantage for the house, and it’s very rare for a gambler to win more than he or she loses. This advantage, known as the “house edge,” can be very small—less than two percent—but it adds up over millions of bets, generating a large profit for the casino.
To combat the potential for cheating and stealing, which is common in casinos because of the huge amounts of cash handled by the staff, most use sophisticated surveillance systems to monitor the action. In addition to video cameras, some casinos use “chip tracking,” in which betting chips have a microcircuitry that allows them to be monitored minute by minute; and roulette wheels are electronically monitored to discover any statistical deviation from expected results.
In addition to cameras, casinos often enforce security through a combination of rules and training for employees. Some casino security personnel are specially trained to recognize signs of problem gambling, and some are even certified to administer counseling and other services to problem gamblers. Other security measures include limiting access to gambling areas, monitoring player behavior, and maintaining separate rooms for high-rollers and regular patrons. In some cases, casinos may require patrons to submit a photo ID or other proof of identity before allowing them to gamble. This is to prevent criminals from using false identities to gain entry to the casino and take advantage of the gambling opportunities there. In addition, most casinos have a zero tolerance policy for drug abuse.
