A casino is a gambling establishment where players can gamble cash or casino chips on games of chance. These games can be conducted by one or more live croupiers, in a game room or on an electronic device. There are three general categories of casino games: gaming machines, table games, and random number games. Gaming machines are those that do not require the involvement of a dealer, while table games involve one or more players competing against the house (the casino). Random number games are based on the selection of numbers by a computerized random number generator.

Some places are known specifically for their casinos, including Monte Carlo and Las Vegas. The largest casino in the United States is located in Thackerville, Oklahoma. It is operated by the Mashantucket Pequot Indian tribe. Some casinos are also renowned for their architecture, such as the Venetian in Macao, which is designed to look like a Venice lagoon city. This casino has been featured in several books, including Ben Mezrich’s Busting Vegas and the James Bond film Casino Royale.

Some casino games are regulated by law, while others are not. In many countries, it is illegal to operate a casino without a license, and some casinos are subject to frequent government raids. Casinos are a major source of revenue for many countries, and they contribute to the economy in various ways. They provide employment, especially to women and minorities, and they attract visitors who spend money on food, drink, lodging, and other entertainment.
