Casino (also known as gaming or gambling establishments) are places where people can play games of chance for money. They are popular forms of entertainment and attract millions of visitors each year. Successful casinos can generate billions of dollars in profits for the companies, investors, and Native American tribes that operate them. They can also provide significant tax revenues for local, state and national governments.

Modern casinos often include a variety of themed attractions such as fountains, shopping centers, and elaborate hotels, but they would not exist without the games of chance on which they are built. Slot machines and table games such as blackjack, roulette, craps, baccarat and poker contribute the most to their profits. These games typically have a built in statistical advantage for the casino that can be as low as two percent.

Patrons may be tempted to cheat or steal, either in collusion with other players or on their own; thus, most casinos employ numerous security measures. These measures may include cameras, surveillance systems, and rules requiring players to keep their hands visible at all times in card games. Some states regulate and license casinos, especially Las Vegas and Atlantic City.

In 2005, Harrah’s Entertainment reports that the typical casino gambler was a forty-six-year-old female from a household with above-average income. Men were more likely to play table games, while women favored electronic gaming.
