A Casino is a gambling establishment where games of chance are played. The word Casino is most often associated with card games like baccarat, blackjack and poker. Other popular games include craps, roulette, keno and slot machines. The Casino generates billions of dollars in profit each year. The word Casino is derived from the Italian “ridotto”, which was a social club for the wealthy that served as a meeting place and venue for various entertainment activities. The precise origin of gambling is unknown, but it is believed to predate recorded history. Primitive proto-dice and carved knuckle bones have been found at archaeological sites, and there is evidence of organized gambling in the 16th century with the rise of the ridotti.

Modern casinos are sophisticated facilities, often featuring high-tech surveillance systems and sophisticated table-game technology. Elaborate chips with built-in microcircuitry enable casino managers to monitor the exact amount wagered minute by minute, and electronic monitoring of roulette wheels reveals quickly any statistical deviation from expected results. Casinos also use cameras to supervise their patrons and staff.

Casinos make money by taking a small percentage of the total bets placed. This is called the house edge, and it ensures that the casino will make a profit over time. The casino advantage varies from game to game but is usually no more than two percent. In addition to the house edge, casinos also earn money through comps, which are free goods or services offered to loyal gamblers. Typical comps include free hotel rooms, meals and tickets to shows. Ask a casino employee or visit the information desk to learn how to qualify for comps.
