What Is a Casino?

A casino is a gambling establishment where people place bets on games of chance or with a small element of skill. Some casinos also feature live entertainment. In the United States, the majority of casinos are found in Las Vegas, although a number exist in other cities such as Atlantic City, New Jersey, and Chicago. Most states have laws that regulate or prohibit casinos. The large revenue generated by casinos is a significant source of tax revenue in some jurisdictions.

In addition to their role as gambling destinations, casinos often serve as tourist attractions. In many cases, they are recognizable by their lavish decor and architecture. The Casino at the Venetian, for example, is designed to look like a grand Italian palace. Its design is meant to impress visitors and make them feel as if they are walking through the streets of Venice.

Some casinos employ advanced technology to monitor and control their operations. For instance, betting chips with built-in microcircuitry enable casinos to oversee the exact amounts wagered minute by minute; electronic systems on roulette wheels detect and warn about any statistical deviations from expected results. Many casinos also use video cameras for general security and to monitor card games for collusion or theft.

Because of the high stakes involved, both patrons and employees at a casino may be tempted to cheat or steal, either in conjunction with others or independently. Because of this, most casinos have extensive security measures in place, including video surveillance and rules of conduct that discourage misconduct.
