A casino is a place where various types of gambling are available. Casinos have a variety of attractions that help to bring in gamblers, from flashing lights and stage shows to free drinks and gourmet restaurants. They also have security measures to prevent cheating and stealing by both patrons and employees.
A successful casino brings in billions of dollars each year for the corporations, investors, Native American tribes and state and local governments that own them. The money is used for various purposes, including building new casinos and maintaining older ones. Casinos are found in many places, from large resorts in Las Vegas to small card rooms on tribal reservations. Casino-type games are also available at racetracks and on boats and barges traveling across waterways.
All casino games have a mathematical expectancy of winning or losing, so it is rare for a casino to lose money on any given day. In addition, all bets must be made within an established limit, which means a patron cannot win more than the casino can afford to pay out. This virtual assurance of gross profit allows casinos to offer big bettors extravagant inducements such as free spectacular entertainment and transportation and elegant living quarters.
A casino’s security starts on the casino floor, where dealers and pit bosses keep an eye out for blatant cheating such as palming or marking cards. Security also keeps an eye out for betting patterns that might indicate a cheating scheme. Elaborate surveillance systems provide a high-tech “eye-in-the-sky” that can be aimed at any table, window or doorway by security workers in a room filled with banks of computer monitors.
