A casino, also known as a gaming house or a gambling house, is an establishment that offers various types of gambling. Many casinos are built as part of resorts, hotels, or even standalone entertainment complexes. Some casinos may have a more traditional and elegant atmosphere, while others may be more modern and flashy. Casinos often offer a wide range of gambling options, including table games, slot machines, and poker. Some casinos also feature a variety of entertainment events, such as concerts and stand-up comedy.

Due to the large amounts of money handled within a casino, both patrons and employees may be tempted to cheat or steal, either in collusion or independently; most casinos have security measures to prevent this. The most basic measure is a series of cameras located throughout the casino. More advanced casinos may have catwalks that allow surveillance personnel to look down directly on the casino floor through one-way glass.

Some of the world’s most famous casinos are renowned for their elegance and sophistication, with some even becoming landmarks in their own right. For example, the Bellagio is known for its dancing fountains and high-end dining options, and was featured in the popular film Ocean’s 11. Other casinos are more massive in size, with some spanning multiple city blocks or even entire countries. The Foxwoods casino in Connecticut is the second largest in America, offering over 350,000 square feet of gaming space and features 380 tables and 6300 slot machines.
