A casino is a public place where people can gamble on various games of chance. Some of these games are played against the house, while others involve skill or against other players. The casino profits from these games through a commission, or “rake”, that it takes from each player. The casino also makes money from games that do not require an element of luck, such as poker, where the house has a mathematically determined advantage.
In recent years casinos have become more sophisticated in their use of technology to control game outcomes. For example, betting chips with built-in microcircuitry enable the casino to monitor the exact amount of money wagered minute by minute, and alert management to any anomaly; roulette wheels are electronically monitored routinely to discover any statistical deviation from expected results. Casinos are also experimenting with computerized surveillance systems to control the behavior of employees and patrons.
The social aspect of gambling is a major draw for many people. In addition to the noise and flashing lights, casinos often offer a variety of food and beverages free of charge, and stage shows or other entertainment. In addition, casino staff may encourage patrons to gamble by offering them complimentary items or “comps” such as hotel rooms, meals, show tickets and airline tickets. Statistically, the typical casino patron is a forty-six-year-old woman from an upper-class family. This demographic accounts for over half of all casino gamblers in the United States.
