What Is a Casino?

A casino is an establishment for gambling. Casinos are often built near or combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. In the United States, casinos are regulated by state and tribal gaming control boards or commissions. Some states have independent gaming associations that advocate for the interests of casino members. Many casinos feature a wide range of games, such as slot machines, blackjack, and roulette. They may also offer video poker, sports betting, and other forms of entertainment.

While the majority of casino games provide a predictable long-term advantage to the house, some have skill elements that can reduce or eliminate this edge. Players with sufficient skills are known as advantage players and can make substantial short-term profits. The most common skill-based casino game is blackjack, which has a house edge of one percent or less when played optimally. Other popular skill-based games include poker (variants such as Caribbean stud), baccarat, and pai gow.

Modern casinos usually have very high security standards and are heavily regulated. They employ a combination of physical security and specialized surveillance departments to monitor casino patrons and employees for signs of cheating, collusion, or other illegal activities. Many casinos use cameras to track the movement of guests throughout their facilities and have catwalks in the ceiling above the gaming floor that allow surveillance personnel to look directly down through one-way glass at the table and slot players. Many casinos are also located on American Indian reservations, which are exempt from state antigambling laws and have their own regulatory authorities.
