A casino is a place where people can gamble on games of chance. It’s believed that gambling in some form has existed since the beginning of recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice found at the earliest archaeological sites [Source: Schwartz]. Casinos as we know them, however, didn’t develop until the 16th century, when a casino craze swept Europe, and Italian aristocrats hosted parties at their homes known as ridotti. The casinos offered a variety of ways to gamble under one roof, including table games and slot machines.
The casino industry generates a lot of revenue for the gaming establishments that host them. Most of this money comes from slot machines, which have become standard attractions in most casinos. The way they work is simple: a player inserts cash, pulls a handle or pushes a button, and the spinning reels display different bands of colored shapes. If the correct pattern appears, the player wins a predetermined amount of money.
Many modern casinos also offer a variety of table games, like blackjack and craps, where players compete against the house (the casino) rather than each other. These games are conducted by live croupiers and require some degree of skill on the part of the players.
In addition to offering a variety of gambling options, most casinos have restaurants, bars, shops and other entertainment amenities. They often reward loyal patrons with free goods and services, such as hotel rooms, meals, show tickets and limo service.
