A casino is an establishment for certain types of gambling. It may also refer to a room or building used for this purpose. The term is a shortened version of the Latin word casin
Slot machines are a standard feature of casinos and generate the largest share of casino income, as they do not require any skill or strategy to play. A player simply places a coin or paper ticket into the machine and pulls a handle or pushes a button. Then, varying bands of colored shapes roll past on reels (either actual physical ones or video representations of them). If the corresponding pattern appears on the paytable, the player wins a predetermined amount of money.
Modern casinos rely heavily on technology to prevent cheating and other forms of criminal activity. For instance, betting chips with built-in microcircuitry allow a casino to monitor the exact amounts wagered minute by minute and quickly warn a dealer of any suspicious behavior; roulette wheels are electronically monitored to discover any statistical deviations from expected results; and video cameras constantly monitor all areas of the casino floor.
In addition to traditional games of chance, casinos offer a wide variety of card games, such as blackjack, poker (both live and electronic), baccarat, and craps. Some casinos also offer Asian-themed games such as sic bo, fan-tan, and pai gow poker.
