A casino is an establishment for certain types of gambling. It may be combined with hotels, restaurants, entertainment venues and retail shops. The term may also refer to a dedicated facility for gaming, such as a freestanding building or an entire island. In some jurisdictions, the casino is a legal entity in its own right.
The modern casino is a massive complex like an indoor amusement park for adults, with the vast majority of the entertainment (and profits for the owners) coming from gambling. Slot machines, black jack, roulette, craps, and keno generate the billions of dollars in profit that casinos rake in each year. Musical shows, lighted fountains and elaborate hotel rooms are all part of the attraction.
Gambling almost certainly predates recorded history, with primitive protodice and carved six-sided dice found at many archaeological sites. However, the casino as a place where people could find a variety of ways to gamble under one roof did not develop until the 16th century. During this time, a gambling craze swept Europe and wealthy Italian nobles would hold private parties in places called ridotti [Source: Schwartz]. Although technically these were illegal casinos, the aristocrats knew just how to avoid the attention of the authorities.
Casinos make money by offering a house edge on most games. This edge can be very small, usually lower than two percent, but over millions of bets it adds up. Casinos may also earn additional revenue from “comps” given to players who spend a lot of money. These can include free hotel rooms, meals, tickets to shows and even limo service and airline tickets.
Security is a key component of casino operations. Casinos have a variety of surveillance systems, from manned cameras to high-tech “eye-in-the-sky” installations. These systems can monitor everything from table moves to player reactions and betting patterns, and can be directed to focus on suspicious patrons. In addition, many casino employees are trained to spot cheating and other unethical behavior.
The casino industry is a major source of employment in some countries and regions. It is estimated that about 1.4 million people work in some capacity within the industry worldwide, with the United States housing the largest number of casino employees. In addition, the industry is a significant contributor to tourism in some destinations. Despite the positive economic impacts, casino operations are not without controversy. Many states have passed laws limiting or banning casino gambling. Some of these laws have been successfully challenged in court, but others remain on the books. The industry also raises concerns about social problems, such as crime and addiction. Nevertheless, the popularity of casino gambling continues to grow. In fact, the casino industry has helped revitalize several once-declining cities.
