A Casino is a place where patrons can gamble on games of chance and win money. Many casinos offer extras such as restaurants, free drinks and stage shows to attract players. There are even more luxurious establishments that add a variety of entertainment options to their gambling facilities, such as hotels and nightclubs.

Gambling has been part of human culture for a long time. The precise origin is unknown, but it is believed that some form of gambling has existed in every society. The modern casino is generally considered to have been invented in America, though the first legalized gambling house was built in 1831 in Nevada by Charles Fey. Many other states soon followed suit, and now 40 U.S. states have some type of legal gambling, with most having a large number of casinos.

Casinos typically use sophisticated security measures to prevent cheating and stealing, both by patrons and staff. They employ several types of surveillance cameras to monitor the gambling floor, as well as electronic systems that supervise game results. For example, betting chips have built-in microcircuitry that enables casinos to monitor exact amounts wagered minute by minute; roulette wheels are electronically monitored for statistical deviations.

In addition to traditional games, some casinos offer more exotic Far Eastern games such as sic bo, fan-tan, and pai gow. They also feature a variety of poker and video poker machines. Most casinos also have a variety of dining options, from fast food to five-star restaurants. Some even offer live entertainment, such as comedy or music, to attract customers.
