A casino is an establishment for certain types of gambling. These establishments can be combined with hotels, restaurants, retail shops or other tourist attractions. The term casino may also refer to a specific game of chance, such as blackjack, roulette or poker. Several countries have legalized casinos, and they can be found in many cities throughout the world.

Casinos generate most of their profits from the vig (or rake) and payout percentages on games such as video poker and slot machines. In addition, they make money by offering free or reduced-fare entertainment and accommodations to large bettors. This is known as comping.

Gambling in some form has been a part of human culture for thousands of years. Historical examples include the Mesopotamian khanate of Susa, Elizabethan England and Napoleon’s France. Modern casino gambling began with the introduction of the Atlantic City gaming house in 1978, and since then casinos have been established worldwide. Most casinos are located in states with antigambling laws, but some have been built on American Indian reservations, which are exempt from state regulations.

In 2005, Harrah’s Entertainment reported that the average casino gambler was a forty-six year old woman from a household with above-average income. These patrons tend to be more likely to spend more than they win, and they often take home fewer winnings than those who play lower stakes. The company cited a national survey, conducted by Roper Reports GfK NOP, that showed 24% of Americans had visited a casino in the previous year.
