A casino is a gambling establishment offering a wide variety of games for players to gamble in. Some casinos offer only table games, while others focus on poker and other card games, and still others feature a combination of both. Some casinos are located within hotels, resorts, or other recreational facilities. Others are stand-alone buildings. In either case, the aim is to draw customers and keep them gambling.
Casinos are usually divided into three main categories: gaming machines, table games, and random number games. Gaming machines, such as slot machines, are typically played by one player at a time and do not require the involvement of casino employees. In contrast, table games, such as blackjack and craps, are often staffed by dealers or croupiers. Random number games, such as keno or roulette, are often conducted by computer programs.
Most casino security is handled by a combination of a physical security force and a specialized surveillance department. The latter operates the casino’s closed circuit television system. In addition, the security staff at many casinos works closely with law enforcement agencies to prevent crime and to apprehend criminals.
In the twenty-first century, many casinos have restructured their operations to make them more profitable. They are concentrating their investments on high rollers, or gamblers who make large bets. These gamblers are sometimes given special rooms where they can wager huge amounts of money. In exchange, the casinos reward them with complimentary services such as free luxury suites and lavish personal attention.
