A casino is a place that offers gambling activities. These casinos can feature games such as blackjack, poker, baccarat, roulette and craps. They are a large source of revenue for their owners and generate billions in profit each year. Modern casinos are usually very lavish in nature and often feature restaurants, free drinks, stage shows and dramatic scenery. However, there have been less extravagant places that housed gambling activities that were still called a casino.
Security is a major concern for casinos and they spend a lot of time, effort and money on it. Casinos have several different layers of security to protect their patrons and property. The first is on the casino floor where employees keep their eyes peeled for any blatant cheating or dishonesty. Dealers are especially trained to spot a range of techniques such as palming, marking and switching cards or dice. Table managers and pit bosses also have a more comprehensive view of the games and can watch for patterns in betting that may signal cheating.
The second layer of casino security is the computer system which keeps tabs on all the bets and pays out winnings. This is linked to a number of cameras throughout the casino and can monitor multiple tables simultaneously. Count rooms keep tabs on the amount of money that is bet, and once a certain amount has been bet it is sent to a supervisor who will bundle it up and put it into an armored car for transport to a bank.
