A casino is a gambling establishment that offers games of chance and skill. It may also offer dining, entertainment and other amenities. Casinos are found in a variety of shapes and sizes, from massive resorts to small card rooms. Casino-type game machines are also found at racetracks and in bars, truck stops and some grocery stores.

Casinos are primarily profit centers for their owners and operators, but they also generate billions in revenue for state and local governments, investors, Native American tribes and other private entities. Some casinos generate even more money by compensating “good” players with free hotel rooms, meals and tickets to shows or other events. The net impact on a community, however, is often negative – the shift of spending away from other forms of local entertainment and the cost of treating compulsive gamblers offset any economic benefits that the casino provides.

Although the precise origin of gambling is unknown, evidence of it exists throughout human history. Its earliest form is thought to be the ritualized throwing of bones or dice, with primitive protodice (cut knuckle bones) and carved six-sided dice discovered in ancient archaeological sites. Modern casino culture grew from the proliferation of legalized gambling opportunities in the United States after state legislatures made it legal to open gaming facilities. In addition to offering a variety of casino games, many casinos feature musical shows, lighted fountains and shopping opportunities to appeal to a wide range of visitors.
