A casino, also known as a gaming house or a gambling establishment, is a place where people can gamble. Casinos can be found in many places around the world, including some that are operated by the state or local government. They may also be combined with hotels, restaurants, retail shops and other tourist attractions. Casinos are also known for hosting live entertainment events, such as concerts and stand-up comedy shows.
Gambling has existed in some form since ancient times, with primitive protodice (cut knuckle bones) and carved six-sided dice being found in some of the oldest archaeological sites. However, casinos as an institution that provides a variety of ways to gamble under one roof did not develop until the 16th century. During this time, a gambling craze spread throughout Europe. Rich Italian aristocrats would hold private parties in venues called ridotti, where they could gamble and socialize. These clubs were technically illegal, but they were rarely bothered by the authorities.
The modern casino evolved from these Italian clubhouses. In the United States, casino gambling first appeared in Atlantic City in 1978. Casinos soon spread to other locations within the United States, particularly American Indian reservations where state laws regulating gambling are not enforced. In the 1980s, casino gambling started to appear in some Latin American countries as well. In addition, during this period many states amended their antigambling statutes in order to allow for casino development.
Because of the large amount of money handled inside a casino, patrons and employees are sometimes tempted to cheat or steal, either in collusion with each other or independently. As a result, security measures are an important part of casino operations. Most casinos employ a number of technological and procedural safeguards, such as cameras. Many casinos also require players to keep their cards visible at all times, and some use special decks of cards.
Casinos make their money by charging a percentage of all bets placed to play games that involve chance. This advantage is called the house edge, and it can vary from game to game. The house edge is larger in games of pure chance, such as slot machines and roulette, than it is in games that require skill, such as blackjack and baccarat. Casinos may also charge a commission, called a vig, on bets placed against the house.
In recent decades, some casinos have expanded to become massive megacasinos that feature hotel rooms, non-gambling games, and other amenities, such as swimming pools, spas and bars. These facilities can be found in cities around the world, including Las Vegas and Macau. They have attracted a number of high-profile visitors, and have been the setting for several popular books and movies. For example, the Monte Carlo Casino was featured in Ben Mezrich’s book Busting Vegas, a story of how MIT students beat the casino out of millions of dollars. Other famous casinos include the Wynn Las Vegas and the Bellagio in Paris.
