A casino is an establishment for gambling. It offers various games of chance, and in some cases skill, and is regulated by government authorities. It may also offer dining, entertainment, and other amenities to enhance the customer experience. Casinos are most famous for their poker rooms, but they also offer many other card and table games, as well as video and lottery machines. Some are located in luxurious hotels, while others stand alone on the outskirts of towns or cities.

Gambling has long been a part of human culture. The earliest known dice were found in China in 2300 BC, and playing cards became widespread by 1400 AD. Today, casinos generate most of their revenue from table and slot machine games. The dazzling lights and joyful sounds of these games create a manufactured euphoria that can keep people coming back, even if they lose money in the long run.

To keep customers happy, casinos have a variety of entertainment options ranging from high-end restaurants to fast-food chains. These dining options increase the financial success of a casino and also provide a break from the frantic pace of the gaming floor.

Most countries have legalized some form of casino gambling. In the United States, there are 2,147 licensed casinos and 619 casino hotels. Many casinos have adopted modern technology to help enforce security and monitor games. For instance, chips with built-in microcircuitry allow casinos to oversee the exact amounts wagered minute-by-minute, and roulette wheels are electronically monitored regularly to discover any statistical deviation from their expected results.
