A casino (also known as a gaming house or casino) is a gambling establishment where patrons can place bets on various events, including poker games and horse races. Casinos are owned and operated by people or companies who make a profit from the money deposited and won by their customers. These profits are made through the addition of a percentage to the winnings or by charging an hourly fee for playing time.

In the United States, casinos are regulated by state law and must operate within specific geographic boundaries. Many casinos are built on Indian reservations, which are exempt from state anti-gambling laws. The earliest casinos were established in Atlantic City, New Jersey and on American Indian reservations. Casinos spread to Europe in the 1980s and 1990s, and are now found throughout the world.

While the majority of gamblers are not experts, those who have sufficient skills can overcome the inherent long-term disadvantage of casino games and sometimes gain a substantial short-term advantage. These players are known as advantage players. The casino industry is concerned that these players are driving up property values in the areas surrounding the casinos, and that their behavior could lead to societal problems. For this reason, casino operators and gambling advocates are seeking to limit the influence of advantage players. Casinos may use a variety of psychological tricks and designs to trick gamblers into spending more money, even though the house always wins.
