A casino is a place where people can gamble. It also has restaurants and bars. Most casinos have gaming machines that accept cash or paper tickets with barcodes. They also have table games, such as blackjack and roulette. Most casinos have a house edge, which is the advantage the casino has over the players. The house edge is usually fixed, but it can vary between games. Some casinos make their profit by charging a commission on poker games, called rakes.

Modern casinos use technology to monitor the games and detect cheating. For example, some casinos have chips with built-in microcircuitry that can be tracked minute by minute; others have electronic systems that oversee the spins of roulette wheels or dice to detect any statistical deviation from expected results. Many casinos have security departments that work closely with these technological systems to prevent crime.

Because of the large amounts of money that pass through a casino, it is possible for patrons and staff to be tempted to steal or cheat. In collusion or independently, they may try to alter the outcome of a game, change the odds, or manipulate other equipment. In addition to a physical security force, most casinos have specialized surveillance departments that operate closed circuit television systems. If this does not deter criminal activity, casino security may also employ methods such as sting operations to catch perpetrators.
