What Is a Casino?

A casino is a place where people can gamble. While gambling probably predates recorded history — primitive protodice (cut knuckle bones) and even carved six-sided dice are found in archaeological sites — casinos didn’t develop until the 16th century, as a result of the great gambling craze that swept Europe at the time. Gambling games that are popular in casinos include blackjack, roulette, craps, poker and slot machines. In addition, many casinos have restaurants and bars.

While elaborate themes, lighted fountains and musical shows may lure visitors to casinos, the majority of a casino’s profits comes from gambling. Slot machines, baccarat, roulette, keno and other table games are what provide the billions of dollars in annual revenue that casinos rake in. The majority of a casino’s security measures are focused on the prevention of cheating and stealing, both in collusion with other patrons and between staff members. Many casinos have catwalks in the ceiling that allow surveillance personnel to look down through one-way glass on table games and slot machines. Other casinos have high-tech “eyes in the sky,” where cameras can be aimed to zoom in on suspicious activity or focus on specific patrons.

Casinos are located in cities and towns across the country and around the world. People travel to these destinations for the chance to win big money and to see how they stack up against other players. While casinos are a major source of income for communities, they can also harm them by stealing money from local businesses and residents. Studies show that the cost of treating compulsive gambling and lost productivity from people who spend their income in a casino outweigh any benefits they bring to a community.
