A casino is a gambling establishment where people can gamble on games of chance or in some cases with a degree of skill. Casino games include slot machines, poker, baccarat, keno, roulette, and blackjack. Some casinos offer a variety of other entertainment, such as musical performances or stand-up comedy. Casinos also serve alcohol and food to their patrons.

Gambling has been part of human culture for millennia. The first evidence of gambling dates back to 2300 BC in China. Dice and playing cards appeared later in history, and baccarat became popular around the 1400s. Modern-day casinos have become much more sophisticated, with a high level of surveillance to protect their customers and profits.

Casinos provide a significant amount of revenue for many communities. These funds can help a city fund important public services, avoid raising other taxes, and/or make needed infrastructure improvements. Casino tax revenues are particularly helpful to poorer areas, where jobs and other economic activity are scarce.

The economic promise of casinos is that they will increase employment in the local area by providing jobs for the people who run and work in the casino. However, this promise may not always be realized. It depends on whether the skilled labor needed for the casino is located in the immediate local area or if it draws skilled workers from outside the community. If the latter is true, then the unemployment rate for the original population will remain unchanged.
