A casino is a place where people can gamble and enjoy various entertaining activities. While the modern casino is much like an indoor amusement park for adults, with musical shows, lighted fountains and shopping centers, the majority of the action (and profits for the owners) comes from gambling on games of chance. Slot machines, blackjack, roulette, craps and keno are just some of the many games that provide the billions of dollars in profits that casinos rake in each year.

A large portion of a casino’s income comes from the house edge on each game. This advantage can be as low as two percent, but it adds up over time and millions of bets. It also allows casinos to spend money on elaborate hotels, fountains and replicas of famous landmarks. While most people think of Las Vegas when they hear the word casino, there are casinos all over the world.

The first modern casino was built in 1638 in Venice, Italy. It was called the Ridotto, and it was the first government-sanctioned casino. Its popularity spread to other parts of Europe, and eventually it made its way to the United States. Today, casino gambling is a global industry with some of the largest gaming facilities in the world located in Nevada and Atlantic City, New Jersey. Other popular casinos include the Mohegan Sun in Uncasville, Connecticut and the Empire at Leicester Square in London, England. Some casinos are known for their celebrity clientele, such as the Caesars Palace in Las Vegas where Frank Sinatra, Liberace and Dolly Parton once performed.
