A casino (or gambling house) is an establishment for certain types of gambling. Casinos are often combined with hotels, restaurants, retail shopping and other tourist attractions. Some casinos also have entertainment venues such as theaters and arenas. Casinos are operated by a variety of organizations, including government-owned or state-licensed enterprises, private companies, and social clubs.

Some casinos feature table games, such as blackjack, roulette and baccarat, which are conducted by live dealers, and others include slot machines, video poker and chemin de fer (or ‘trente et quarante’ in French). The house edge of a casino game is the built-in advantage that the house has over the players, either because of the rules of the game or due to the fact that the house takes a vig or rake on each bet. Casinos earn their money from these advantages, which are mathematically determined and can vary based on the game played and the payout percentage set by the game designer.

Casinos strive to make their gambling environment as welcoming as possible and encourage gamblers by offering perks such as complimentary rooms, meals and show tickets. The concept of comps originated in Las Vegas during the 1970s, and they are now offered by most casinos to the highest-volume gamblers, especially those who play table games like blackjack or poker for long periods of time.

Many people consider casinos to be glamorous and exciting places, and some have even referred to them as a “resort”. However, studies have shown that the economic benefits to a community from casino gaming are minimal, and the social costs associated with problem gambling can offset any gains.
