A casino is a place where people gamble by playing various games of chance. It may also feature other entertainment options such as restaurants, free drinks and stage shows. It is possible to win money at casinos, but it is not guaranteed. The house has several advantages over the players, which make it more likely that they will lose in the long run.
Gambling in one form or another has existed throughout history, with primitive protodice and carved six-sided dice found at the earliest archaeological sites [Source: Schwartz]. Casinos as venues for gambling did not appear until the 16th century, when a craze for gaming swept Europe and Italian noblemen held private gambling parties at places called ridotti. These were essentially private clubs, and although they violated the law, they were seldom bothered by authorities.
Modern casinos are designed to appeal to as broad a range of visitors as possible, with many offering several different types of games. In addition to the standard games of chance like slots and blackjack, casinos also feature a variety of Asian games such as sic bo (which spread to several European and American casinos in the 1990s) and fan-tan. Many casinos offer sports betting, and some feature race tracks and bingo halls.
Casinos are a popular destination for tourists and locals alike, but they must provide security to prevent theft and cheating. Due to the large amounts of cash that pass through their doors, both patrons and employees may be tempted to steal or cheat, either in collusion or independently. To prevent this, casinos use a wide array of security measures. These range from the basic, such as security cameras located throughout the casino, to more sophisticated measures such as fingerprint scanners and infrared sensors.
