A casino is a place where people can play various games of chance for money. The word is derived from the Latin casin, meaning “to chance”. In modern usage, a casino may refer to a large building that houses many gambling activities. It may also refer to a place that offers luxury amenities to attract customers.

Most casinos offer a wide variety of games, including blackjack, craps, roulette, and video poker. In addition, they often host concerts and other events. Some are connected to hotels, restaurants, and spas. Casinos are also found on cruise ships and in some states where it is legal to operate them.

Casinos are regulated by law in most jurisdictions and are overseen by government agencies. Despite this, critics argue that they are harmful to the economy because they divert spending from other types of local entertainment and can lead to compulsive gambling. They also argue that the costs of treating problem gamblers and lost productivity offset any economic gains.

In the United States, there are over 1,000 commercial casinos and hundreds of tribal casinos. Most of them run daily and weekly poker tournaments and games. Most of the big casinos in Las Vegas and Atlantic City feature multiple poker rooms. Other popular games include baccarat, which is especially common in Asian casinos. In addition to these games, most casinos offer a full range of slot machines. In the United States, this includes classic three-reel and five-reel machines as well as newer video poker offerings.
