What is a Casino?

A casino, or gambling hall, is a place where people play games of chance for money or other goods. The word is derived from the Latin casinum, meaning “house” or “room.” Gambling has been an integral part of human culture for millennia, with evidence dating back to 2300 BC in China. Dice appeared in Rome around 500 AD, and card games like poker emerged in the 1400s. Casinos have expanded to include restaurants, bars, and retail operations.

Many casinos employ security measures to prevent cheating and stealing by patrons, both collusion among players or on their own, especially given the large amounts of cash handled in a casino. The most basic security measure is video surveillance. Many casinos also have catwalks in the ceiling above the gaming floor that allow surveillance personnel to look directly down, through one-way glass, on the activities at the tables and slot machines.

Because of the inherent risks involved in gambling, casinos have to ensure that their house edge and variance are low enough to guarantee a net profit for each bet placed by a patron. To do this, they hire mathematicians and computer programmers who specialize in this field to analyze the games and devise rules that will give them a mathematical advantage. This is known as game theory.
