A casino, or gambling house, is a place where people gamble. It can be as big as a Las Vegas resort or as small as a neighborhood card room. There are also floating casinos on barges and boats and racinos at racetracks. Successful casinos generate billions in profits each year for owners, investors and state and local governments.

Gambling has been a part of civilization for millennia. Archaeological evidence suggests the use of dice in China around 2300 BC, and playing cards showed up in Europe in about 1400 AD. Casinos have grown to incorporate all forms of gambling, from simple games with a bookie to the elaborate table games found in modern casinos.

In many ways, casinos have a built-in customer base. People enjoy the excitement of gambling and the opportunity to win. Winning can also provide a temporary escape from the everyday problems that many people face in their lives. And a visit to a casino can be an inexpensive and exciting way to spend time with friends or family members.

The term casino derives from the Italian city of Casino di Venezia. Originally, the name was used to describe a small clubhouse for social occasions, but it eventually came to refer to the entire industry. Today, the term casino is used to describe everything from the high-end casinos in Monaco and Las Vegas to the small, privately run gambling houses in Italy. Casinos are not just for gambling; they offer entertainment, dining, spas and theaters.
