In the context of gambling, a casino is an establishment where customers gamble by playing games of chance or skill. Most casinos also offer a wide variety of other games and entertainment. Casinos are most often found in hotels and resorts, entertainment complexes, restaurants, retail shops, cruise ships, and other tourist attractions. Some casinos may be operated by the government, while others are private businesses. The precise origin of gambling is unknown, but it is generally believed to have existed in many societies throughout history.

Casino games are usually based on probability and mathematics, with some incorporating an element of skill. Casino games are regulated by gaming laws to ensure fairness and prevent cheating. The house edge is the mathematical advantage that the casino has over players, assuming that they play optimally (without counting cards). In games of chance that require skill, the house edge can be minimized by using card-counting techniques. In games in which players compete against each other, such as poker, the casino earns money through a commission, called the rake.
