A casino is a gambling establishment where people gamble by playing games of chance or skill. Some casinos also offer a variety of dining and entertainment options. In the United States, there are more than 1,000 casinos. Las Vegas has the largest concentration of casinos, while Atlantic City and Chicago are second and third, respectively. Most casinos are operated by Indian tribes, and are often located on tribal land. Some casinos are open to the general public; others are restricted to members only.

A number of security measures are commonly used in casinos to prevent cheating or theft by patrons or staff. These include cameras, security guards and rules of conduct that require players to keep their cards visible at all times. In addition, some casinos have a dedicated security team that investigates reports of misconduct or suspicious activity.
