The word casino is a combination of two Latin words meaning “public house” or “large room.” In the United States, it usually refers to a large entertainment complex that offers a variety of gambling activities. In a more restricted sense, the term may also refer to a building or room where certain types of social amusements are held, especially those featuring dancing and gaming. Many casinos are upscale establishments that cater to high-wagering guests.
The term is most often associated with Las Vegas, although there are casinos in other cities such as Atlantic City, New Jersey; Chicago, Illinois; and Denver, Colorado. Some casinos are part of larger hotel and resort facilities, while others are standalone structures. Many casinos feature a wide variety of entertainment options, including restaurants, bars, nightclubs, and/or live performances. Some even offer spas and golf courses.
Casinos use a variety of tricks to draw in gamblers, including bright and sometimes gaudy floor and wall coverings that are designed to stimulate the senses and create excitement. Some casinos avoid using clocks on their walls, because they are believed to cause patrons to lose track of time and spend more money.
In a 2002 survey of Nevada citizens who reported gambling activity, Gemini Research found that the most popular casino games among those who played them were slot machines and video poker. About half of the respondents chose these games, while card games (such as blackjack and poker) were favorites of about a third. Other games included table games like roulette and craps, as well as bingo and keno.
Most casino games have a mathematically determined advantage for the house, which is called the house edge. This gives the house a profit no matter how much is bet or what game is played. The exceptions are baccarat and some table games, which allow players to make decisions that affect the outcome of the game. In those cases, the house’s advantage is smaller than in other games.
Some casinos have programs that reward frequent gamblers with comps, such as free meals and show tickets. In addition, they may tally up the amounts spent by players to develop a profile of their average wagers and game selections. This information is helpful for marketing purposes and helps the casino identify its best patrons, which can be used to target advertising directly to them. Some casinos have also adapted loyalty programs from the airline industry to increase their revenue stream and improve customer service. Many of these schemes require that gamblers swipe their player cards electronically before each play, so the casino can keep a record of their gambling habits. This also makes it easier for staff to spot problem gamblers and limit their access to the casino.
