In the United States, a casino is an establishment where people can gamble and be entertained. Most casinos offer a variety of gambling games, including blackjack, poker, craps and roulette. Some also have sports books, race tracks and other attractions. Many casinos are associated with hotels and resorts.

In addition to promoting responsible gaming, state laws typically require that casinos display information about problem gambling and provide contact details for organizations that can provide specialized help. The information is usually included on a casino’s website.

Casinos are designed to maximize gambling revenue by attracting as many customers as possible. They offer a wide range of free items to entice gamblers, often called “comps.” These might include food, rooms or show tickets. Casinos may also give out limo service and airline tickets to high-volume players.

Most games in a casino have a built-in house advantage, which is sometimes called the house edge or vigorish. This advantage is a small percentage of the total amount of bets placed, but it adds up over time. The casino profits from this vigorish, as well as from table games and a small commission on video poker payouts.

The typical casino patron is a middle-class to upper-class white person who is over forty. This demographic makes up the majority of the casino gambling market in the United States. Casinos target this group because it has the money to gamble and enjoys being around other people.
