A casino is a place where games of chance are played and where gambling is the primary activity. Its luxuries and perks like restaurants, free drinks and stage shows help draw in patrons, but casinos would not exist without the gambling activities that bring in billions of dollars in profits each year. Craps, keno, roulette, blackjack and other games of chance are the heart of casinos.

Gambling probably existed before recorded history, but the concept of a casino as an entertainment center that houses many different types of gambling did not develop until the 16th century. At that time, a craze for gaming swept Europe. Aristocrats often held parties in places called ridotti, where they could play a variety of games under one roof.

While modern casinos offer many types of games, most of them are based on mathematically determined odds that give the house an advantage over the players. A percentage of all wagers is taken by the casino as profit, and this is referred to as the house edge. Some games, however, have an element of skill that makes the outcome of the game more unpredictable. These games are known as “table games”.

In the early days of casino gaming, mobster money flowed into Las Vegas and Reno to finance the expansion of casinos and their lavish luxuries. Later, real estate investors and hotel chains saw the huge potential of casinos and pumped their own money into the business. With federal crackdowns on organized crime, the mob’s involvement in casinos faded away.
