What Is a Casino?


A casino is a place where people gamble and play games of chance. It has many extras to attract customers, such as stage shows and dramatic scenery. The modern casino is like an indoor amusement park for adults, with most of its entertainment coming from gambling. Slot machines, blackjack, roulette, craps, keno and other games provide the billions in profits that casinos rake in each year.

Gambling probably predates recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice found in ancient archaeological sites. But the modern casino didn’t develop until the 16th century, when a gambling craze swept Europe. Casinos were built to serve the needs of this new fad, and they quickly became places where patrons could find many different types of gambling under one roof.

Casinos have several advantages over players, including a built in advantage known as the house edge. This advantage, which can be quite small (less than two percent), is how a casino makes money. It can also be referred to as the vig or rake. In the long run, this edge earns casinos enough money to build elaborate hotels, fountains, pyramids, towers and replicas of famous landmarks.

Something about gambling—perhaps it’s the presence of large amounts of cash—seems to encourage cheating and stealing, which is why casinos devote such a large amount of time and effort to security. Surveillance cameras monitor the floor, and employees watch patrons to make sure they are not stealing or manipulating cards or dice. Some casinos even have catwalks that allow surveillance personnel to look down, through one-way glass, on activities at table games and slots.

Most casinos try to evoke a sense of luxury, and the decor can vary greatly from place to place. But the overall theme is often a rich, exotic style that appeals to the senses and emotions. The lighting is carefully controlled to create a mood and make the patron feel as though they’re in another world.

In addition to a variety of games, most casinos offer free drinks and meals. Some are open 24 hours a day, while others have specific hours of operation. Some also offer special bonuses for high rollers, who are frequent visitors and spend a lot of money. These bonuses can include things such as free hotel rooms, dinners, show tickets and limo service.

In the past, some casinos were owned by mobster families, and their employees often worked for the mafia. But as real estate developers and hotel chains began investing in the industry, they bought out the mob owners and started operating their own casinos without mob interference. Today, mob ties to casinos are rare, and federal regulations and the threat of losing a gaming license at the slightest hint of Mafia involvement keep organized crime out of the business.
