A casino is a place where people can gamble by playing games of chance, or in some cases, skill. These games include blackjack, roulette, poker and craps. Casinos often provide free entertainment and luxury accommodations to their patrons. They may also offer a wide variety of restaurants, bars and non-gambling activities.
In addition to security cameras, casinos rely on employees to watch over their operations and to spot suspicious actions by patrons. Dealers are heavily focused on their own game and can quickly spot blatant cheating like palming, marking or switching dice or cards. Table managers and pit bosses have a much wider view of the table games and can easily pick up on betting patterns that could be indicative of cheating. Casinos use technology to monitor the games themselves as well, with some using systems that allow them to track how much money is wagered on each machine minute by minute; and others using electronic methods to regularly check for statistical deviation from expected results.
Casinos are often located in opulent buildings designed to impress, and they strive to make their facilities as exciting as possible to draw in new customers and keep existing ones coming back. They use the latest technology to attract people, from security cameras to sophisticated gaming machines that can handle millions of dollars in wagers per hour. They use dazzling lighting and visual displays to enhance their ambience, and they use the latest audio-visual technology to synchronize their music with the sound effects produced by the machines. They even employ top-notch stage performers to entertain their guests.
