A casino is a gambling establishment where customers gamble on games of chance, and in some cases, skill. These games include roulette, baccarat, blackjack, poker and video poker. Casinos have many security measures to prevent cheating and stealing. They also monitor patron behavior for suspicious activities. If a security officer spots a problem, they can alert other officers or the gaming manager.
The name casino derives from the Latin tabula, meaning table. The word was applied to the game of hazard, or risk, played on boards with Roman square points, as well as the obelisk-shaped points found on the Gloucester tabula set from around 700 AD. The game was adapted to European countries, and in the twentieth century casinos became more sophisticated with the advent of high-tech surveillance systems.
In the 1990s, casinos dramatically increased their use of video technology. They now employ a “video eye in the sky,” where cameras constantly scan tables, windows and doors. In addition to cameras, casinos employ special chips that track betting activity. The chips have built-in microcircuitry that interacts with electronic systems on the table, allowing the casino to oversee exact amounts wagered minute by minute. The system can also discover any statistical deviation from expected results.
Another way casinos make money is by charging a rake, or commission, for card games. This is a percentage of each bet that the house takes. This money is used to pay the dealer, and it is usually collected by a croupier who sits behind the cards. Casinos also take a cut of the profits from slot machines, which are operated by the players by pushing buttons.
Casinos make much of their money from high bettors, or “high rollers.” These people spend a lot of money on wagers and often gamble in separate rooms, away from the main floor. They are favored by the casino with free or reduced-fare transportation, luxury suites and other inducements.
In general, a casino makes its money through the rake from table games and the house edge from slot machines. It is very rare for a casino to lose money on its games, and the profit margins are very high.
The average casino patron is a forty-six-year-old female from a household with an above-average income. Casinos try to keep these patrons happy by creating a comfortable atmosphere and minimizing their awareness of time passing while they gamble. Lush carpets, dim lighting and luxurious decor are common features. A large prize, such as a sports car, is often displayed prominently.
