A casino is a gambling establishment where people can gamble on games of chance. Many casinos also offer other types of entertainment, such as live shows or sports events. In some countries, casinos are licensed and regulated by the government. A casino can be a standalone building, or it may be part of a larger hotel and entertainment complex. Often, casinos are combined with hotels, restaurants, retail shops, and cruise ships.
Some people consider casinos to be socially harmful, arguing that they divert local spending away from other forms of entertainment and that compulsive gambling contributes to crime. In addition, some economists believe that casinos do not bring any net economic benefit to their host communities.
Security is a major concern for casino operators. In addition to cameras and other technological measures, employees patrol the floor and watch customers. The routines and patterns of casino games create an environment where it is relatively easy for security personnel to spot cheating or other suspicious activity. For example, the way dealers shuffle and deal cards and the locations of betting spots on table games follow certain patterns. Likewise, players at poker and other card games must keep their cards visible at all times.
During the 1950s and 1960s, organized crime figures controlled much of the gambling in Reno and Las Vegas. Mobster money poured into the casinos, but legitimate businessmen were reluctant to invest their own capital in casinos because of their seamy reputation. Eventually, real estate investors and hotel chains bought out the mobsters, and casinos became less dependent on mob money.
