A casino is an establishment where gambling games are played. Casinos are most commonly found in resorts, hotels and restaurants. They can also be built on cruise ships or at tourist attractions. In some countries, casinos are operated by governments. In the United States, they are licensed and regulated by state law. Most of the world’s casinos are located in Las Vegas, Nevada.

A modern casino is a complex building that features multiple gaming floors, restaurants, bars and other entertainment options. Modern casinos are also designed to be environmentally friendly and incorporate sustainable design principles. A large part of the modern casino’s revenue comes from electronic slot machines and table games, which require a great deal of skill to play well. These games can be addictive, so casinos have developed programs to prevent players from becoming addicted.

In the early 20th century, the elegant spa town of Baden-Baden was a playground for European royalty and aristocracy. Its casino was inspired by the baroque flourishes of Versailles. Today it is a popular gambling destination that attracts high rollers from all over the world.

Because of the large amount of money that is handled within a casino, both patrons and employees may be tempted to cheat or steal. This is why most casinos have security measures in place. These include security cameras mounted throughout the facility, as well as catwalks that allow surveillance personnel to look down on the tables and machines from above.
