A casino is a building or room where gambling games are played. It can be as large as a massive Las Vegas resort or as small as a neighborhood card room. Casinos can be owned by individuals, companies, or Native American tribes. They can be located on land or at sea, in cities or in rural areas. They may also be part of larger entertainment complexes, such as those containing hotels and restaurants. In some states, casinos are operated on the grounds of racetracks or other facilities licensed by the state to offer gambling.

Casinos attract visitors from all over the world and generate billions of dollars in profits each year for the businesses, investors, and players who operate them. In addition to offering a variety of gambling opportunities, these establishments provide numerous other amenities and services. Some even include top-notch hotels and spas, along with stage shows and other forms of entertainment.

Gambling has been a part of human civilization for millennia. The precise date is unknown, but archeological finds suggest that dice were in use by 2300 BC and that card games first appeared around 500 AD. By the 1600s, the game now known as blackjack was in wide use.
