A casino, also called a gambling establishment or gaming hall, is a place where people play various games of chance for money. The games played in casinos are primarily based on luck, but some have an element of skill. Casinos are usually staffed with croupiers or dealers who deal the games. They are often decorated with bright and gaudy colors that stimulate the players and make them lose track of time. They may also feature exotic locales or have music and entertainment.

Casinos earn billions of dollars each year for the companies, investors, Native American tribes and state governments that operate them. They also generate revenue from taxes and fees that are paid by patrons who gamble there. Casinos are regulated by federal and state laws.

Gambling in its various forms has been around for thousands of years. It was common in ancient Egypt, Greece, Rome and other cultures. In modern times, casino gambling is legal in some countries and prohibited in others. It is a popular form of entertainment and many famous people have performed at casinos, including Frank Sinatra, Liberace, Cher and Dolly Parton.

Most casinos offer free drinks and food while patrons gamble, as well as luxury accommodations for high rollers. The amount of money that can be won at a casino depends on the rules and policies established by each property. Typically, a higher amount of money spent equals a greater chance of winning. Casinos may offer players complimentary items, known as comps, based on the amount of their wagers. They may also charge a percentage of the total winnings, known as the vig or rake.
