A casino is a gambling establishment, a facility for certain types of gambling. Casinos are often combined with hotels, restaurants, shopping centers and other entertainment venues. Most of the time, a casino’s profits come from its games of chance, such as slot machines, blackjack, roulette and craps. The word casino comes from the Italian “casa” meaning house, and it was used as early as the 16th century to describe private clubs for members to gamble and socialize. It wasn’t until the gambling craze of the 1700s that the term became widely used to refer to any place where people could find a variety of ways to gamble.
Casinos go to great lengths to lure and keep patrons gambling as long as possible, spending as much money as they can. Large companies invest millions of dollars in determining what colors, sounds and scents appeal to players most. They also employ professional marketers and psychologists to develop strategies that make big bettors feel like VIPs, offering them free spectacular entertainment and transportation, room service, elegant living quarters and even reduced-fare hotel rooms.
While casinos aren’t immune to fraud, they use advanced technology to monitor their games and watch out for cheaters. For example, poker tables feature chips with built-in microcircuitry that allow the casino to oversee the exact amounts wagered minute by minute; a roulette wheel is electronically monitored regularly to discover any statistical deviation from its expected results. Moreover, dealers are trained to spot blatantly obvious cheating patterns.
