A Casino is a gambling establishment that offers a variety of games of chance. It typically adds luxury amenities to attract players, such as restaurants, free drinks and stage shows, and it often includes a dramatic setting.

There are thousands of casinos around the world, including those in the United States. Most are large resorts, but some are small neighborhood or family-friendly establishments.

Modern casinos have specialized security forces that patrol the floors of the casino and respond to reports of criminal activity. A specialized surveillance department also operates the closed circuit television system in casinos.

The most popular games in casinos are slot machines, which use reels of varying bands of colored shapes to make predetermined combinations that win money. Other casino games include poker and roulette.

High rollers (gamblers who spend more than average) are a large source of profit for casinos. They are usually allowed to play in special rooms away from the main casino floor, where the stakes can be in the tens of thousands of dollars.

Comps are also given to players based on the amount they spend and the amount of time they play. These include free hotel rooms, dinners, tickets to shows and even limo service.

Casinos are a popular tourist attraction, and they have a significant impact on the local economy. However, they can hurt property values in local housing markets. They are also a major cause of problem gambling and addiction.
