What Is a Casino?

A casino is a gambling establishment offering a wide range of games of chance to patrons who are willing to wager money. Most casinos are open to the general public, although some are members-only clubs. The world’s most famous casinos have become iconic symbols of luxury, romanticized in film and literature with images of high-stakes gaming tables surrounded by a select group of guests in tuxedos and evening gowns.

A large percentage of the world’s casinos are located in Las Vegas, Nevada; however, there are also a number in exotic locations such as Venice, Italy; Monaco; Singapore; and the elegant spa town of Baden-Baden, Germany. Many of these casinos are luxurious resorts in their own right and offer a variety of amenities beyond the gaming floor, including restaurants, bars, and even theaters.

As the popularity of casino gambling has increased, so too has the sophistication of casino security measures. Various types of technology are used to prevent cheating and theft, both by patrons and casino staff. These include security cameras; table games such as blackjack and craps with built-in microcircuitry that allow the casino to monitor the exact amount of money being wagered minute by minute; and roulette wheels that are electronically monitored for any statistical deviation from their expected results.

A casino’s business model is based on the principle that it is not a charity organization giving away free money; the house always wins. This fact is reflected in the house edge, the average profit the casino expects to make from each game played by a patron. This advantage, which is a combination of various factors, gives the casino an inherent mathematical edge over the players.
