Casino is a gambling establishment that features a variety of games of chance and skill. Guests gamble by using chips, and the house takes a percentage of the winnings. Some casinos also offer complimentary items, known as comps. Comps are usually given to big spenders and may include free hotel rooms, meals, tickets to shows or even limo service and airline tickets.

Some casinos have table games, such as craps, blackjack, and poker. Other tables may feature far Eastern games, such as sic bo and fan-tan, or regional variations on those games, such as trente et quarante in France and chemin de fer in the United States. Card game fans will be pleased to learn that some casinos offer video poker and various roulette variants, too.

Successful casinos take in billions of dollars annually, providing jobs and revenue for investors, corporations, and local governments. The profits also help local businesses and attract tourists to cities and towns. In addition to the obvious benefits, however, some critics claim that casino operations harm communities by attracting people away from other forms of entertainment and reducing property values. They also contend that the high costs of treating problem gambling and lost productivity due to addiction negate any positive economic effects.

Although gambling almost certainly predates recorded history, the concept of a place where people could find a wide range of gambling activities under one roof did not emerge until the 16th century. In Italy, the aristocracy hosted private parties, called ridotti, in which they would gamble and socialize, while concealing their activity from the authorities.
