What Is a Casino?

A casino is a public place where games of chance are played and gambling takes center stage. While musical shows, lighted fountains, shopping centers and lavish hotels add to the fun of a casino visit, the billions in profits made each year by casinos would not be possible without games like blackjack, roulette, craps and keno.

Casinos have been around in some form for centuries, from the world’s oldest, which is located on Venice’s Grand Canals and accessible by a free boat shuttle service, to the Las Vegas strip where people arrive from all over the globe. There is a casino somewhere in the world for every type of gambler, from those who prefer high-stakes poker rooms to those who like the flash and glitz of slot machines.

While the games of chance are what draw in the money, casino security is a top priority. Casinos employ a variety of technological and human methods to ensure that no one cheats, steals or otherwise skews the results. Security personnel patrol the gaming floors to keep an eye out for blatant techniques, such as “palming” (switching hands) or marking cards; pit bosses oversee the table games and keep a close watch on betting patterns; and casino employees are trained to spot shady behavior.

Computerized surveillance systems allow casinos to monitor all the activity on the floor, minute by minute; and electronic monitoring of tables helps them keep an eye out for shady dealings. Moreover, the rules of most games require that players keep their cards visible at all times and do not touch them while playing. In some cases, the game must be stopped if it becomes obvious that a player is not following the rules.

Because casinos operate with such a mathematical expectation of profit, it is very rare that they lose money. In fact, it is not uncommon for a casino to make millions of dollars in profits in a single day. As such, they are able to offer big bettors extravagant inducements in the form of free spectacular entertainment and reduced-fare transportation and hotel rooms.

Even with all the luxuries and excitement, many people still consider casinos to be socially undesirable places. Problem gambling is a major concern, as evidenced by the prevalence of gambling addictions, which disproportionately generate a large percentage of casino profits and result in losses to the community from lost productivity and social services costs. Some studies also indicate that the net effect of a casino in a community may be negative, as gamblers shift their spending from other local forms of entertainment and may actually reduce property values.

Casinos also impose a significant tax burden on the communities in which they operate, which some critics say reduces their social value. However, others argue that casinos attract tourist dollars that would not otherwise be spent locally and that the economic benefits of the gambling industry outweigh the negative impacts on local businesses and housing markets.
