A casino is a building where people gamble and play games of chance. From the time when miners pursuing gold in the Nevada mountains took weekend bus trips to the local card room, casinos have become an integral part of America’s leisure activities. Today, you can find a casino in just about any major city in the United States.

Modern casinos are like an indoor amusement park for adults, with musical shows, lighted fountains and themed hotels drawing in the crowds. But the bulk of their profits come from gambling. Slot machines, blackjack, baccarat, roulette, craps and keno generate the billions in profits that make the casinos possible.

While many people visit casinos for the thrill of gambling, the industry is not without its problems. Problem gambling is a real issue and can be devastating to a person’s finances, health and personal relationships. To combat this issue, casinos are required to display responsible gambling signage and provide specialized support services as part of their licensing requirements.

While gambling has been around for thousands of years in one form or another, casinos became a popular form of entertainment in the mid-19th century. Originally, they were designed to entertain wealthy patrons, but they quickly became popular with everyone from miners and loggers to ordinary people. With the introduction of railroads, Americans had access to new destinations for their gambling fix. Then, in the 1980s and 1990s, states such as Iowa legalized riverboat casinos and Atlantic City opened. Currently, Nevada and New Jersey lead the nation in the number of casinos.
