What is a Casino?
Casino is a gambling establishment where customers gamble by playing games of chance and in some cases with an element of skill. Casinos often have a luxurious atmosphere and feature opulent furnishings. They also offer entertainment and dining, and are known for attracting high rollers and the rich and famous.
Casinos earn most of their money from slots and table games, including roulette, baccarat, craps, blackjack, and poker. Most of these games have mathematically determined odds that give the house an advantage over the players. This advantage is commonly known as the house edge. In games like poker where the players compete against each other, the casino takes a commission, called a rake, from the pots.
Modern casinos use technology to supervise games and detect any statistical deviations from expected results. For example, chips with built-in microcircuitry allow the casino to monitor and record betting patterns minute by minute; roulette wheels are electronically monitored regularly to discover any abnormalities. Video cameras and other surveillance equipment are also used to keep tabs on gamblers.
Casinos are located in cities, towns, and resorts across the globe. Some, like the elegant spa town of Baden-Baden in Germany, first opened their doors to royalty and aristocracy 150 years ago. Others, such as the Venetian in Macau, China, are enormous mega-resorts that cater to affluent tourists from around the world. Some are even designed to look like ancient Roman or Byzantine palaces. These temples of temptation are equipped with opulent furnishings, dozens of slot machines, and a full-service bar.
