A casino is a place where people play a variety of games of chance. These may include roulette, gaming tables for card games and dice, slot machines, and other gambling equipment.
The history of casinos dates back to the 16th century, when a gambling craze swept Europe and Italian aristocrats held private parties in places called ridotti [Source: Schwartz]. Despite being illegal, these clubs often avoided legal repercussions by focusing on one aspect of the social event – gambling.
Today, most casinos feature a wide variety of games to attract players, and they earn the majority of their revenue from slots. These machines are simple devices that spin bands of colored shapes, and a player must match a certain pattern to win money.
Elaborate surveillance systems allow security personnel to watch all the tables at once. These cameras change windows and doorways, and they can focus on suspicious patrons to find out if they are cheating or not.
Table managers and pit bosses also keep an eye on the entire casino floor, making sure everyone is playing fair and that all the players aren’t stealing from each other. They can spot blatant cheating at the tables, like palming or marking cards or dice.
Many casinos use bright and gaudy flooring and wall coverings to attract gamblers. Red is a popular color, and it has the effect of stimulating and cheering gamblers.
