A casino is a public place where gambling activities take place, and it offers restaurants, bars, shops, spas, theaters and top-notch hotels. However, the main attraction remains gambling. Slot machines, blackjack, roulette, craps, keno and baccarat generate the billions in profits that casinos rake in every year.
While gambling in its various forms has predated recorded history, the casino as a place that brings together a variety of ways to gamble under one roof did not evolve until the 16th century. Prior to that, gamblers found a variety of games of chance all over the world, from primitive protodice and carved six-sided dice to the elaborate ridotti (private parties for aristocrats) and fluttering whirlpools of Renaissance Italy.
Gambling is a popular pastime in most countries, but it also comes with some inherent risks. The large amounts of money handled within a casino are attractive to both patrons and staff, who may attempt to cheat or steal, either in collusion with others or independently. For this reason, casinos have security measures in place to prevent such behavior. Security cameras and electronic monitoring systems are common, while table managers and pit bosses supervise table games to spot any unusual betting patterns or blatant stealing.
Because of the high percentage of games that have a mathematical expectation of winning, it is very rare for a casino to lose money in any given day. This virtual guarantee of gross profit enables casinos to offer big bettors extravagant inducements, including free spectacular entertainment, transportation and elegant living quarters.
