What Is a Casino?

A casino is a place where people gamble on games of chance and in some cases skill. The games include slot machines, blackjack, roulette, craps, baccarat, and poker. Casinos make money by establishing a house advantage, or expected value, over the players. This advantage can be as small as two percent, but it adds up over the billions of dollars in bets placed each year. The house edge is sometimes referred to as the vig or rake, depending on the game. Casinos also earn profits from offering perks to high-stakes patrons, such as free spectacular entertainment and luxury living quarters.

Casinos are regulated by federal and state laws. They are usually located in areas that attract tourists and business travelers, such as resorts, cities, and cruise ship ports. The United States is home to the most casinos, with the majority located in Nevada and Atlantic City. Many casinos are privately owned by individuals or corporations, but a few are owned and operated by organized crime syndicates.

Because large amounts of cash are handled within casinos, there is a high risk of cheating and stealing by patrons and employees. This is why casinos have security measures in place. Casino staff keep an eye on the games and patrons to spot blatant cheating techniques, such as palming or marking cards. Elaborate surveillance systems provide a “eye-in-the-sky” that allows security personnel to monitor every table, window, and doorway. Cameras can be adjusted to focus on suspicious patrons.
