What Is a Casino?

A casino is a gambling establishment where people gamble on games of chance or skill. These games include poker, blackjack, craps, roulette, and baccarat. In addition to these games, casinos often offer shows and fine dining. Most casinos are regulated by law.

Unlike other types of gambling, which may be done in private or in groups, most casino games are played in public. As a result, the noise level is high and patrons can be heard shouting encouragement or frustration. Many casinos also provide drinks and snacks to their customers, although the consumption of alcohol can impair gambling ability.

In the United States, casinos are most famous for their presence in Las Vegas and Atlantic City, but they have spread to other parts of the country, especially on American Indian reservations, where state laws do not prohibit them. Casinos are also increasingly being established on riverboats and in other remote locations, including Puerto Rico.

Casinos make money by charging their customers for the use of their facilities and generating tax revenue for their home cities. They also focus on customer service, providing free items (known as comps) to frequent players. During the 1970s, for example, Las Vegas casinos gave out travel packages and cheap show tickets in order to attract as many people as possible to their establishments.

Some casino operators are infamous for their mob ties. However, real estate investors and hotel chains with deep pockets eventually bought out the mobster owners of casino properties and now run them without any mob interference.
