A Casino is a gambling establishment where many types of chance-based games are played. These games may include poker, baccarat, blackjack, roulette and craps. In addition to gambling, casinos also often host stage shows and other forms of entertainment.

In order to ensure the integrity of their games, casinos have implemented a number of security measures. These measures typically begin on the casino floor itself, where employees keep an eye on patrons to prevent blatant cheating and theft. In addition to this, security workers also keep an eye on the patterns and routines of specific casino games. This allows them to quickly spot any deviation from the expected behavior of a particular game.

Another aspect of casino security involves the use of technology to supervise games themselves. This includes the use of video cameras, a system called chip tracking, and electronic systems that supervise the spinning of roulette wheels and the placing of bets on table games. These technological systems enable casinos to monitor the exact amount of money wagered minute by minute and to quickly detect any statistical deviation from expected results.

Most casinos have a customer loyalty program that rewards frequent patrons with free or discounted meals, drinks and tickets to shows. Some have clubs that function much like airline frequent-flyer programs. In the past, casinos tended to cater to high-rollers and offer them extravagant inducements. Today, however, casinos are choosier about whom they invite to their facilities.
