What is a Casino?

A casino is a place where people gamble in cash or other value, on games of chance or skill. Casinos can be found in many places, from massive resorts to small card rooms. Successful casinos bring in billions of dollars each year for the companies, investors, and Native American tribes that own and operate them. Governments at the local, state, and federal levels also reap casino revenues in taxes and fees.

Unlike lotteries and Internet gambling, which involve isolated players, casino gambling is social in nature. Players interact with one another, shout encouragement, and often drink alcohol while playing. The atmosphere is designed around noise, lights, and excitement; a red color scheme is typically used to stimulate the senses and increase player energy.

Because casinos deal with large sums of money, security is an important concern. To discourage cheating and theft, most casinos use some form of video surveillance. In addition, some casinos employ specialized mathematics to track game outcomes and house edges; these people are called gaming mathematicians or gaming analysts.

Some casinos offer traditional Far Eastern games such as sic bo, fan-tan, and pai gow. Others feature more familiar table games such as blackjack, craps, and poker. In some countries, casinos may also offer keno or bingo.
