A casino is a building that houses gambling activities. It may add luxuries such as restaurants, free drinks, stage shows and dramatic scenery to draw in players but at heart the casino is a place where people play games of chance for money. Whether they be a single table or an entire building, casinos have been in operation for centuries.

While casinos are often associated with the glitz and glamour of Las Vegas, they can be found in cities around the world and even on cruise ships. They can also be found on racetracks as racinos and in truck stops, bars and other small businesses. Successful casinos generate billions of dollars a year in profits for the companies, investors, Native American tribes and local, state and federal governments that own and operate them.

Gambling probably existed before recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice found at ancient archaeological sites. However, the modern casino as a place where patrons could find a variety of ways to gamble under one roof did not develop until the 16th century, during a gambling craze that swept Europe.

Unlike the flamboyant decor and free drinks that characterize many casinos today, early gambling establishments were more drab and spartan. But as the industry evolved, casinos began adding more attractions to draw in customers. Today, for example, the best casinos are able to provide high-stakes gamblers with their own private rooms where they can bet tens of thousands of dollars at a time. In addition, casinos offer their loyal customers “comps,” or complimentary goods and services.
