A casino is a building or room where gambling games are played. These games are usually based on chance, but some have an element of skill. Most casinos also offer food and drink, stage shows, and other entertainment. Some countries have legalized casinos, and others have banned them. Some, like Macau (East Asia’s version of Las Vegas) are famous for their extravagant luxury and glamour.
A modern casino often has many security measures in place to prevent cheating or tampering. These include video cameras, electronic surveillance systems, and highly trained staff. Table managers and pit bosses keep close tabs on the games, and can quickly spot blatant cheating such as palming, marking or switching cards or dice. Casinos are very sensitive to any suggestion of mob involvement, and federal crackdowns and the threat of losing their gaming license mean that they have little tolerance for even the slightest hint of organized crime.
Casinos vary in size and style, but all have the same basic features: tables for card games and table gambling, slot machines, and a variety of other gambling equipment. Generally, all bets are placed within an established limit, and the house has a mathematical expectation of winning. This advantage is known as the house edge. In games where players play against each other, the house takes a commission known as the rake. Because of the expected return on investment, most casinos are designed to attract high rollers and offer them free or reduced-fare transportation, hotel rooms, meals, spectacular entertainment, and other inducements.
