A casino, also a gambling hall or gaming establishment, is a facility where adults can play games of chance for money or other prizes. The best casinos in the world offer an impressive array of games, top-notch hotels, spas, restaurants and entertainment.

Something about gambling (or perhaps the presence of large amounts of money) seems to encourage cheating and stealing, whether in collusion or independently. This is why casinos devote a great deal of time and money to security measures. Cameras are positioned throughout the facility to watch patrons and games, and electronic monitoring systems like “chip tracking” enable a casino to oversee the exact amounts wagered minute by minute; roulette wheels are electronically monitored regularly to discover any statistical deviations from expected results.

There are, of course, more subtle aspects of casino security. Dealers, for example, follow certain routines when they shuffle and deal cards, or when they clear their hands after placing bets. These patterns are easily recognizable by casino security personnel and can alert them to possible suspicious activity.

Because of the relatively high house edge on most casino games, casinos almost always make a profit. However, a casino’s true profitability is determined by the amount of money it can attract and retain. This is why big bettors are often offered extravagant inducements like free spectacular entertainment, hotel rooms and even limo service and airplane tickets. These comps offset the house edge and allow a casino to attract more players.
