A casino is a place where people can gamble on games of chance, and some with an element of skill. Some casinos also offer other entertainment such as live music or comedy shows, and some are combined with hotels or resorts. Many casinos are located in Las Vegas, Nevada, but many others can be found in other countries. Some casinos are quite small, while others are huge and very opulent.

Casinos employ many people to monitor the activities of patrons and prevent cheating or stealing. They use video cameras and other surveillance systems to keep an eye on everyone. In table games, pit bosses and table managers watch over the players with a wide-angle view to detect any suspicious betting patterns. Many casino employees are former dealers who know how to spot a range of tricks that can be used to steal chips.

Something about gambling entices people to try and cheat, steal or scam their way into a jackpot. Some casinos use a number of technological measures to prevent these types of incidents, such as chip tracking, which allows them to follow the movement of individual bets minute-by-minute; and roulette wheels are electronically monitored to discover any statistical deviation from their expected value. Casinos also hire mathematicians and computer programmers to analyze game odds and house edges.

While casino owners often claim that they create jobs and boost tourism in the communities they serve, studies show that compulsive gambling drains local economies by diverting spending from other forms of entertainment. Additionally, the cost of treating problem gambling and lost productivity from addicted workers can offset any economic benefits a casino may bring.
