A casino is a gambling establishment that offers a variety of games for patrons. It also features restaurants, bars and live entertainment. In some places, casinos are combined with hotels or resorts.

A large part of casino gambling is based on card games such as poker. These games are typically dealt by a dealer and are conducted with croupiers. Roulette, blackjack and craps are also popular games at many casinos. These games usually require an element of skill and strategy in order to win. The advantage that the house has over the players is relatively small, and the games are generally played at high speeds.

Casinos have a significant impact on the economy of cities such as Las Vegas and Atlantic City, where they are major sources of income. Many American states have laws that regulate casino gambling. Some of these laws allow casinos to be operated on reservations, which are exempt from state anti-gambling statutes.

Casinos often provide various forms of help and support for problem gamblers, including hotlines, self-exclusion programs and counseling. In addition, many states have their own programs and resources for those who are struggling with gambling addiction. In the US, the National Council on Problem Gambling operates a 24-hour helpline and provides counseling and other services. In addition, some casinos have their own support centers. These are staffed by professionals and are designed to help problem gamblers. In some cases, casinos may even offer free treatment.
