A casino is a place where people can gamble and participate in other entertainment activities. Casino games are based on chance and in many cases have an element of skill. Some games involve rolling dice or playing cards, while others have a mechanical device like a slot machine that produces random numbers. In some cases, casinos also host poker games where players compete against each other.
Gambling probably predates recorded history, with primitive protodice and carved six-sided dice having been found in some of the world’s most ancient archaeological sites. However, the casino as a gathering place for a variety of gambling activities did not develop until the 16th century in Italy during a gambling craze, when Italian aristocrats would meet in private clubs called ridotti to gamble and socialize [Source: Schwartz].
Modern casinos are massive venues that feature a mindblowing number of gaming tables and slot machines. In addition to the standard range of casino games, they usually offer restaurants, hotels, non-gambling game rooms, bars, swimming pools and spas. Casinos are a major source of income for many cities and countries.
The majority of casino games have a mathematically determined house edge, giving the casino a profit over patrons’ bets. To offset this, some casinos offer free or reduced-fare transportation, elegant living quarters and other inducements to attract high bettors. This virtual assurance of gross profit makes it rare for a casino to lose money on a particular day.
