A casino, or gambling house, is a place where people can take part in games of chance. It usually has a bar or a cafe and is staffed by croupiers, who deal the games. Casinos are regulated by state laws. Many casinos also offer live entertainment and tournaments.

Gambling is an ancient activity, with some form of it found in most societies around the world. Modern casinos are often combined with hotels, restaurants, theaters, retail stores and cruise ships. Some casinos are operated by governments, while others are private companies. Most countries have legalized casinos, or at least regulate them. Casinos are also popular with tourists and are often located near major attractions, such as beaches or ski resorts.

Most casino gambling is not social in nature, but the casino atmosphere is designed to be noisy and exciting. It is common for players to shout encouragement, and alcoholic drinks are frequently served at the tables. Many casinos also offer free nonalcoholic beverages and snacks.

Casinos usually have a high house edge, or mathematical expectancy of losing money. To offset this, they offer a variety of promotional incentives to attract gamblers. Large bettors are rewarded with free spectacular shows, expensive transportation and elegant living quarters. Lesser bettors are offered reduced-fare transportation, hotel rooms, free food and drinks while gambling and other inducements.
