Casino is a place where people can gamble in various ways. Some casinos are known for offering free items to players such as food and drinks or limo service, and some are famous for their elaborate gambling environment. People travel the world to experience a new casino. Some travel to a particular city specifically because it has a casino, and others accidentally stumble upon casinos while visiting other cities.
Although the concept of gambling dates back thousands of years, the casino as a place for people to find many different ways to gamble under one roof did not develop until the 16th century, when a casino craze swept Europe and Italian aristocrats began holding private parties in venues known as ridotti [Source: Webster’s New World College Dictionary, 4th Edition]. These parties were technically illegal, but authorities rarely bothered the aristocrats, since they only gambled on horse races, dice, or card games.
Today, casinos offer everything from slot machines to roulette and baccarat, as well as video poker and blackjack. Most games have mathematically determined odds, which ensure that the house will win at all times. This advantage, called the house edge, is a key component of casino profitability.
Casinos also employ a variety of security methods. For example, video cameras are used to monitor table games and the movements of customers; specialized chips with built-in microcircuitry allow the casino to oversee the exact amounts wagered minute by minute; and roulette wheels are electronically monitored for anomalies. These techniques can detect and alert security personnel to potential problems before they become serious.
