A Casino is a place where people gamble on games of chance such as blackjack, roulette, craps, and slot machines. Casinos often have lavish hotels, restaurants and entertainment venues where pop, rock, jazz, and other artists perform for players. While musical shows, lighted fountains, shopping centers and elaborate hotels help draw crowds, casinos would not exist without games of chance such as poker, baccarat, and craps.

While gambling likely predates recorded history, the casino as a venue for many different types of gaming did not appear until the 16th century in Italy as part of a gambling craze. These early venues were called ridotti and were private clubs for Italian aristocrats. Because they were technically illegal, ridotti were seldom bothered by the police.

Modern casinos have become huge operations with multiple gaming facilities connected to high-end restaurants and entertainment venues. Guests can wager on almost any game of chance from a variety of electronic devices. Elaborate security measures include cameras that watch every table, window and doorway. Computerized systems also monitor the results of each game, identifying any statistical deviation from expected performance. Some tables even use betting chips with built-in microcircuitry to monitor exact amounts wagered minute by minute and warn the dealer of any improbable patterns that could indicate cheating. All of this technology helps the casinos to maintain their built-in advantage, and that’s why it’s important to understand how a casino makes money before you play.
