A casino is a public place where games of chance are played. It may also offer table games such as blackjack, baccarat and poker. A casino may be located in a building or room that is devoted entirely to gambling or it may include a number of separate gaming rooms. Casinos often feature stage shows and dramatic scenery to enhance the atmosphere. They may also have bars and restaurants that serve food and drinks to players. Some casinos are so elaborately furnished that they look like palaces.

Gambling has been a part of human culture throughout history. It is believed that some form of gambling has been practiced in every society. The exact origin of gambling is unknown. It was probably a means of settling disputes between people or perhaps a way to entertain.

Some of the most famous casinos are in Las Vegas, Nevada. Other famous casinos are in Atlantic City, New Jersey and Macau, China. A few Native American casinos have also opened. Casinos are also known for their elaborate security systems. For example, some casinos have catwalks that allow surveillance personnel to look down on the activity in the gambling floor. Some casinos also have cameras in the ceiling that can be focused on suspicious patrons.

Because of the large amount of money handled within a casino, both patrons and staff may be tempted to cheat or steal, either in collusion with one another or on their own. For this reason, many casinos have strict rules of conduct and behavior and use security cameras to enforce these rules. Security measures also may include a system of rewards for frequent patrons called comps. These may include free hotel rooms, meals and show tickets.
