What Is a Casino?

A casino is a gambling establishment that offers patrons the opportunity to gamble. Typically, casinos include a variety of gaming tables and slot machines and offer a range of other entertainment options. They may also include restaurants, retail shops, and other tourist attractions. In some cases, a casino may be combined with a hotel or resort.

In the United States, the largest concentration of casinos is in Las Vegas, Nevada. However, several other cities and regions have significant numbers of casinos as well. Many American casinos are located on Indian reservations, which are exempt from state anti-gambling laws. Additionally, since the 1980s, many American states have amended their gambling laws to allow for Native American casinos.

Casinos are businesses and, as such, they must make a profit. To achieve this goal, casinos employ a number of strategies to ensure their profitability. First, they provide players with games that have a built in statistical advantage for the house (the house edge). This edge can be small, but over time it earns the casino enough money to offset its expenses and generate a net profit.

Another way casinos make money is through a percentage of each bet placed by the player, called the vig or rake. This charge is most often applied to table games, though some casinos also impose it on video poker and other games. Finally, casinos often rely on a combination of physical security forces and a specialized department to monitor their closed circuit television system.
