What Is a Casino?

A casino is a gambling establishment that offers various types of games of chance and, in some cases, skill. Some of the most popular games include blackjack, poker, craps, and roulette. Some casinos also offer video poker and keno. All casino games have a built-in house advantage over players, which can be very small but is sufficient to make the casino a profitable enterprise over time. The house edge is the amount by which a game’s expected value is less than the total bet placed on it. This is calculated as a percentage of the total bets made or, in the case of games where patrons play against each other, as a fixed amount per hour charged to the players. This percentage is sometimes referred to as the vig or rake.

In addition to the games, casinos often offer complimentary items (comps) to gamblers. These may include free drinks and food, reduced-fare transportation or hotel rooms, and tickets to shows and other events. The perks are intended to attract and keep gamblers. Since the early twentieth century, casinos have been especially geared towards high-stakes gamblers, offering them luxury perks and private rooms in which to play.

While gambling probably existed in some form long before recorded history, the modern casino emerged during the 16th century as part of a gambling craze that swept Europe at the time. The first modern casinos were in cities such as Monte Carlo, which was a major source of income for the principality of Monaco, and in Paris and other European cities. Casinos have since spread throughout the world and continue to be a major industry in some countries and regions.
