A casino is a special establishment where people can gamble on games of chance, and sometimes skill. Often the casino’s name will indicate which games are available, and may also list the house edge for each. In addition to gambling, casinos often offer restaurants, bars and hotels, as well as other forms of entertainment. Successful casinos can bring in billions of dollars each year for the companies, investors and Native American tribes that run them.

Although they have many amenities to draw in the public, casinos exist primarily to make money from gambling. The modern casino is like an indoor amusement park for adults, with the vast majority of entertainment (and profits for the owner) coming from gambling. The casino industry is regulated in many states. Some are privately owned and operated, while others are owned and operated by the state or a local government. The largest casinos can be found in Las Vegas, Atlantic City and Macau, but there are also many smaller facilities.

In addition to the standard array of game tables and slot machines, most casinos will have poker rooms, and some even host world-class events such as the World Series of Poker. The poker rooms are a key element of casino revenue, and they have a particular appeal to older men with above-average incomes. This demographic makes up the largest group of casino gamblers, according to surveys by Roper Reports GfK NOP and the U.S. Gaming Panel by TNS.
