A casino, also known as a gambling house or gaming palace, is an establishment for certain types of gambling. Casinos are usually located in or combined with hotels, restaurants, retail shops, and cruise ships and often feature live entertainment such as concerts and stand-up comedy. In the United States, casinos are usually licensed and regulated by the state where they are located.
Security is a key part of casino operations. Casinos have strict rules about what a patron can and cannot do on the floor, and employees are trained to spot suspicious behavior. Casinos use cameras to monitor all activity on the floor and have an “eye in the sky” — cameras that are mounted in the ceiling to watch every table, window, and doorway. These cameras are adjustable and can be focused on specific patrons to spot suspicious patterns.
Casinos are mathematically designed to ensure that they make a profit, albeit one that is relatively small compared to the total amount of money wagered. Casinos hire mathematicians to study game theory and figure out the best way to structure their games to maximize profits and minimize losses. This analysis is usually done by hand, but some casinos use sophisticated software to analyze game results and predict winnings.
In the early days of the Las Vegas Strip, casinos competed to attract gamblers by offering free shows and transportation, discounted hotel rooms, and even food and drinks while they were gambling. Today, these perks are still offered but are more likely to be offered to high rollers who spend significant amounts of money.
