A casino is a place where gambling activities take place. A casino may add luxuries such as restaurants, free drinks and stage shows to attract customers. In the United States, casinos are regulated by state law. They may be privately owned, operated by a city or the government, or publicly owned and run. Many states have legalized casinos to help generate revenue and promote tourism. Nevada is known internationally for its casinos. Atlantic City, New Jersey, and Chicago also have a high number of casino establishments.
In modern times, the security of a casino is usually divided between a physical force and a specialized surveillance department. The physical force patrols the premises and responds to calls for assistance or reports of suspicious or definite criminal activity. The specialized surveillance department operates the casino’s closed circuit television system, known in the industry as an “eye-in-the-sky”.
Casino patrons gamble by playing games of chance and, in some cases, skill. Most casino games have mathematically determined odds that ensure the house always has an advantage over the players, which is called the house edge. In some games, the house edge is minimal (e.g., blackjack) while in others it is large (e.g., craps). Casinos hire gaming mathematicians to analyze the game odds and calculate their house edges. The mathematicians and computer programmers that work for casinos are called gaming analysts. This analysis is critical for the financial success of a casino. However, studies show that a casino’s net contribution to the community is negative because it shifts spending from other forms of local entertainment and increases costs associated with compulsive gambling.
