A casino, or gaming house, is a place where people wager money on games of chance. These games may include slot machines, poker, baccarat, blackjack, and roulette. Some casinos offer sports betting and horse racing. Many of these places have elaborate themes, dazzling lights, and luxurious rooms. People of all ages enjoy visiting them for the thrill of gambling and the opportunity to win big prizes. Some of these establishments have a reputation for being seedy and have even been associated with organized crime. Nevertheless, they draw in millions of visitors and are responsible for billions of dollars in profits each year.

Modern casinos are equipped with sophisticated security measures. These may include a physical security force that patrols the casino and responds to calls for help or reports of suspicious or definite criminal activity. Most casinos also have a separate department that oversees their surveillance system, sometimes referred to as the “eye in the sky.” This technology allows security workers to monitor all activity within the casino, and to spot anomalies.

In addition to monitoring patrons, modern casinos use their surveillance systems to protect the integrity of their games. These measures may include specialized cameras that monitor the results of certain games, such as dice and wheel of fortune. Generally, these cameras are located in a special room that is monitored by security workers. Casinos that cater to high-rollers (people who bet large sums) often have specially configured rooms. They also give these bettors complimentary goods or services, such as free hotel rooms, limo service, and airline tickets.
