A casino is a place where people can gamble and play games of chance. It is generally a large, noisy establishment with games of chance and table games like poker, blackjack, craps, roulette and baccarat. It may also have restaurants, free drinks and stage shows. It is possible to find casinos in almost every city and town in the United States. The most famous casino is probably the one in Las Vegas. Other famous casinos are located in Atlantic City, New Jersey and Chicago, Illinois.

Casinos make money by taking a percentage of each bet made by patrons. The exact amount taken varies by game and can be as little as two percent, but it adds up over millions of bets. The house advantage is sometimes called the vig or the rake. Casinos also offer complimentary items to frequent players, known as comps. This can include hotel rooms, meals, tickets to shows and even limo service and airline tickets.

Many casinos have been associated with organized crime in the past, especially when they were first established in Nevada. In the 1950s mobster money began to flow into Las Vegas and Reno, helping to finance expansion and renovation. The mobsters often got involved personally, and even took sole or partial ownership of some casinos, and they used their muscle to keep out rivals and influence the outcome of some gambling games. The image of casinos as places of vice and corruption has lingered to the present day.
