A casino is a gambling establishment that offers a variety of games of chance. These establishments are often combined with hotels, restaurants, retail shops and other tourist attractions. In some countries, casinos are licensed and regulated by government agencies to ensure that they meet certain industry standards. Many famous casinos have become cultural landmarks and attract tourists from around the world.

The term casino has been used in a number of ways, including as a synonym for a public hall for music and dancing; by the second half of the 19th century, it came to refer to a collection of gaming or gambling rooms. It also became a popular name for a public house in the UK, especially one frequented by the working class.

Most modern casinos offer a wide variety of games, including slot machines, blackjack, roulette, and poker. Some are known for their luxurious atmospheres and top-notch service. Others are renowned for their spectacular decor and impressive size. They are often designed to appeal to a wide range of customers, from high-rollers to families with children.

Casinos make money by charging a percentage of the total amount bet to players. This percentage is sometimes called the vig, vigorish, or rake, and it can vary from game to game. The vig gives the casino a mathematical advantage over the average player, which is how it makes its money. In addition, some casinos earn revenue from the sale of drinks, snacks, and cigarettes to patrons. Because of the high amounts of cash handled within a casino, both patrons and employees may be tempted to cheat or steal from each other.
