A casino is a gambling establishment where patrons wager money by playing games of chance or skill. Gambling is regulated in most countries by laws governing gaming facilities and the types of bets that may be placed. In the United States, casinos are mostly located in Las Vegas, Nevada, though there are some in Atlantic City and Chicago. Many American Indian reservations also operate casinos, as these locations are exempt from state antigambling statutes.

Casinos are staffed by croupiers and other casino employees, who monitor patrons to prevent cheating or theft. They also enforce rules of conduct and other behavioral standards. In addition, security personnel use cameras to watch casino activity and ensure that patrons are not stealing or committing other crimes. Using these techniques, they can detect suspicious movements or betting patterns and quickly stop a crime in progress.

Due to the large amounts of currency handled within a casino, both patrons and staff may be tempted to cheat or steal, in collusion or independently. These temptations can lead to stress, anxiety, and depression in some players, so it is important for them to practice self-care by seeking help if they feel distressed.
