What is a Casino?

A casino is a place that sells gambling games. These games include slot machines, poker, blackjack, roulette, craps, keno, bingo and other games. Casinos also have a variety of entertainment options, such as musical shows and lighted fountains. The money that patrons spend at casinos provides most of the profits to the owners of these businesses.

Gambling probably predates written history, with primitive protodice and carved six-sided dice found in ancient archaeological sites. The modern casino evolved in the 16th century during a gambling craze that swept Europe. Italian aristocrats gathered in private gambling clubs called ridotti to gamble, drink and socialize.

Modern casinos are heavily invested in security and technology. Video cameras provide a high-tech eye in the sky that allows security personnel to supervise every table, window and doorway, and spot even tiny statistical deviations from expected results. Electronic systems monitor betting chips with microcircuitry and keep track of how much money is being wagered minute by minute; wheel spinnings are electronically monitored to detect any anomalies.

While casinos are a major source of revenue, they have a number of problems that hurt the communities they operate in. They have a negative impact on local property values and cause addiction to gambling. Moreover, they can attract organized crime figures and become magnets for illegal activities, such as drug dealing and extortion. As a result, the federal government has cracked down on them and made it difficult for legitimate businessmen to get involved in casinos. However, real estate investors and hotel chains have more money than mobster gangsters, so they have stepped in to take over the businesses that the mafia once ran.
