A casino (also referred to as a gambling establishment) is a building or room where people can gamble. Many casinos are combined with hotels, restaurants, retail shops, and/or other tourist attractions. In the United States, the largest concentration of casinos is in Las Vegas and Atlantic City.

Responsible gambling is an important aspect of the casino experience. Casinos support this by offering a wide range of features and programs that help players maintain control over their gambling activities. These include self-limitation options, deposit restrictions, time management controls, and access to gambling support organizations.

A casino’s security measures may also include cameras, trained staff, and rules of conduct. These are designed to prevent both cheating and theft by either patrons or employees. Because large sums of money are handled within a casino, it is important for both the security staff and patrons to be aware of their surroundings at all times. The presence of security personnel is especially important when the casino hosts live games, such as baccarat and roulette. The house advantage in these games is much greater than that of other casino games.
