A casino is a large facility that houses gambling games such as poker, blackjack, and roulette. It is also known as a gaming house or club. A casino is a popular form of gambling and has been around for millennia. Its roots go back to 2300 BC in China, when archeologists found wooden blocks used for gambling games. Dice appeared in Rome around 500 AD, followed by card games in the 1400s. The modern casino has become a major center for entertainment and tourism.

In addition to gaming, a casino can host live entertainment events, including concerts and sporting events. It may also offer dining options, including buffets and restaurants. It can also be a destination for shopping and other forms of recreation.

Gambling is a key component of the economy of many states, and casinos provide significant employment opportunities. They also generate significant tax revenues for local governments. The large amounts of money handled in a casino make it susceptible to theft and fraud, and security measures are designed to prevent these activities. Cameras are commonly placed throughout a casino, and employees are trained to spot suspicious activity.

Casinos are often built on or adjacent to a hotel, forming a complex with restaurants, bars, and gambling rooms. They can also be located on American Indian reservations, which are exempt from state antigambling laws. Some states have even created regulatory bodies to oversee casinos. In addition to the traditional casino, modern technology has enabled new types of gambling. These include lottery-type games and interactive video machines that allow players to control the action.
