A casino is a place where people play games of chance for money. Modern casinos are like indoor amusement parks for adults, with the majority of entertainment coming from gambling. Slot machines, black jack roulette, craps, keno and baccarat are the games that provide the billions in profit that casinos rake in every year. Musical shows, lighted fountains and shopping centers draw in the crowds, but casinos wouldn’t exist without these games of chance.

While gambling may predate recorded history, the modern casino as a place to find many different ways to gamble under one roof didn’t develop until the 16th century. It was during this time that the craze for gambling reached its peak in Europe, with Italian aristocrats frequenting private clubs called ridotti to enjoy their favorite pastime. Although technically illegal, the ridotti weren’t bothered by the authorities, and the popularity of the gambling craze ensured that they would continue to operate.

Since then, casinos have become increasingly popular around the world. Casinos are found in cities and towns, on American Indian reservations, and even on cruise ships. The largest concentration of casinos is in Las Vegas, with other major gambling establishments located in Atlantic City, New Jersey and Chicago. Most of these establishments are regulated by state laws, but some are privately run and financed. Due to the large amounts of currency handled in casinos, both patrons and staff may be tempted to cheat and steal, either in collusion or independently. This is why security measures are a big part of a casino’s infrastructure.
