A casino is a building where people can gamble and play games of chance. This type of establishment is a popular destination for both tourists and local residents alike.
Gambling is an activity that predates recorded history, but the concept of casinos began in the 16th century when a gambling craze swept Europe. Aristocrats would hold private parties in these places, known as ridotti [Source: Schwartz].
The most famous example of a casino is the Monte Carlo in Monaco, which has long been a major source of income for that city. Other principal European casinos are found in Deauville, Biarritz, and the Riviera.
Many casino games are played by a variety of players, including blackjack, roulette, and poker. These games have different rules and are based on different odds, but the result is that casinos make money.
Some casinos have special security forces that patrol the building, while others use elaborate surveillance systems that allow surveillance personnel to watch the entire casino at once through catwalks in the ceiling and one-way windows on the casino floor. This allows them to spot suspicious behavior, such as palming or switching cards or dice, and also helps them identify if someone is cheating.
American casino gaming is primarily based on slot machines and video poker, but games of chance are sometimes offered as well, such as blackjack and baccarat. Casinos can adjust the odds and payouts of these games to suit the needs of their patrons, but the average player is usually unable to win big enough to make a substantial profit.
