A casino, or gambling house, is an establishment where people can play various types of gambling games. Some casinos are combined with hotels, restaurants and other entertainment venues. In the United States, the most famous casino is probably the Bellagio in Las Vegas. The casino was made famous by the film Ocean’s 11 and is a popular tourist destination for both casual and high-stakes gamblers.
Casinos make their money by accepting bets on various casino games, including slot machines, blackjack, roulette, craps and baccarat. These games have a mathematical advantage for the house that is built into them, and casinos are able to earn billions of dollars in profits each year. This advantage is known as the house edge, and it can vary from game to game. In games that require a certain amount of skill, the house advantage is lessened, but the casino still earns a commission from players called the rake.
While gambling in some form has likely existed since the beginning of recorded history, it did not become a central part of society until the 16th century. During this time, Italian aristocrats would hold private parties at homes known as ridotti, where they could wager and drink without worrying about legal consequences. These houses grew in popularity, and the term casino became synonymous with these exclusive social clubs [source: Schwartz].
Today’s casino is more like an indoor amusement park for adults, with high-end hotels, elaborate fountains, shopping centers, musical shows and other forms of entertainment. Nevertheless, the primary source of revenue for most casinos is still games of chance.
