A casino is an establishment for gambling. These casinos often combine with hotels, restaurants and other entertainment venues, and offer a variety of games such as blackjack, poker and roulette. They may also host live entertainment such as concerts and stand-up comedy.

Many casinos have security measures in place to prevent cheating and stealing by patrons. These measures can include a physical security force and specialized surveillance departments. The latter usually operate the casino’s closed-circuit television system, known as a “eye in the sky.” Casinos may also have special rules and limits for specific types of bets or machines.

Some cities are known for their casinos, such as Monte Carlo, which is a popular destination for gamblers. Las Vegas is the largest casino city in the world, and Atlantic City is the second. Other cities, such as Chicago, have casinos, but are not necessarily defined by them.
