A casino, also known as a gambling house or a gaming establishment, is a place where people can play various types of gambling games. These facilities are often combined with hotels, resorts, restaurants, retail shops and other tourist attractions. Casinos can be found in a variety of locations, including cities, states, and countries around the world.

A significant aspect of the casino experience is live entertainment. The most famous casinos are home to a variety of top-tier performers, from Celine Dion and Elton John to Bette Midler and Rod Stewart. The casinos also offer an array of other amenities, such as top-rated hotels and spas.

Some casinos have a specific theme, such as those based on ancient Egypt or the Wild West. Others, such as those in Monte Carlo and Singapore, are renowned for their elegance. The most popular game in a casino is probably blackjack, followed by roulette and poker. Card games that require skill, such as baccarat (in the English-speaking world) or trente et quarante (in French-speaking countries), are played less frequently, but are still offered in some casinos.

In the United States, the most prominent casinos are located in Atlantic City and Las Vegas. Other important venues include the Monte Carlo Casino, which is both a casino and a tourist attraction, and the Foxwoods Resort and Casino in Connecticut, a massive facility operated by the Mashantucket Pequot Tribal Nation. Casinos have also become increasingly common on American Indian reservations, which are not subject to state antigambling laws.
