What Is a Casino?

A casino is a place where people gamble and play games of chance. While a modern casino offers a host of luxuries to help lure in gamblers, such as restaurants, free drinks, stage shows and dramatic scenery, casinos would not exist without the games of chance that are the basis for the billions in profits they make every year.

Gambling almost certainly predates recorded history, with primitive protodice and carved six-sided dice found in archaeological sites. But a casino as a place where a variety of ways to gamble could be found under one roof didn’t emerge until the 16th century, when a gambling craze swept Europe. At that time, aristocrats held private parties at facilities known as ridotti (little rooms), where gambling was the primary activity and the aristocrats weren’t bothered by the fact that the venues were technically illegal.

Modern casinos look like giant indoor amusement parks, with music and lighted fountains helping to attract the crowds. But the bottom line for the owners is the games of chance, and slots, blackjack, roulette, craps, keno, and poker are what brings in the money.

While some gamblers are drawn to the excitement of the game, others are lured by the promise of big winnings. The most lucrative customers are the high rollers, whose wagers can be in the tens of thousands of dollars. To keep them happy, the most reputable casinos have a wide range of security measures in place. Those include cameras, staffers who watch the games to spot any suspicious activities, and rules that require players to keep their hands visible at all times in card games.
