A casino is a place where people can gamble on games of chance or skill. In games such as poker and blackjack where players compete against the house, a casino employee deals the cards and collects a commission called the rake. A casino also offers other entertainment such as shows and restaurants. The most famous casino is in Las Vegas, but there are many others around the world.

A modern casino is usually a large facility that contains several gambling rooms. The rooms are decorated in bright, often gaudy colors that stimulate and cheer the gambling patrons. The casino also employs bright lighting and loud noises to create an exciting and stimulating atmosphere. The sound of coins dropping into a slot machine is designed to be particularly appealing to the human ear. Various scents are used to further enhance the experience.

Casinos have a very high profit margin and are therefore highly profitable businesses. However, they must take steps to ensure that gambling is carried out fairly and ethically. Casinos are required to have a high level of security to prevent theft and other forms of fraud. They are usually protected by a physical security force and a specialized department that oversees closed-circuit television surveillance.

The majority of casino gambling is done by women, and older adults, especially those with above-average incomes. According to research conducted by Roper Reports GfK NOP and the U.S. Gaming Panel by TNS, a typical casino customer is a forty-six-year-old woman from a household with above-average income.
