A casino is a place where people can gamble. Casinos usually have gambling games such as poker, blackjack, roulette and slots. Some casinos also offer entertainment, food and drink. They are often found in tourist destinations and near hotels. The casino industry is highly competitive and is regulated by law. Casinos may be prone to cheating and theft by patrons and staff, so security measures are important. Casinos use cameras and other technology to monitor their facilities.

The precise origin of gambling is unknown, but it is believed to have existed in almost every society throughout history. The first modern casinos began to appear in the second half of the 20th century, after many American states changed their laws on gambling. These new casinos largely replaced horse racing tracks and riverboat gambling. The most famous casinos are located in Las Vegas, Nevada, and Atlantic City, New Jersey. Casinos can also be found on many American Indian reservations, where they are not subject to state anti-gambling laws.
