A Casino is a place where people can gamble for money. These establishments are called casinos for two reasons, the house and the banker. In the 21st century, casinos have almost the same character around the world. The growth of casinos outside of Las Vegas and Atlantic City is partly due to Native American gaming. Security is a major concern in casinos, since patrons and staff may be tempted to cheat or steal. Many casinos employ security measures, including security cameras and guards on the premises.

A casino must calculate the house edge and variance for each game to ensure the highest possible profit. The house edge tells the percentage of the casino’s profit that the player will make, and the variance determines the cash reserves. To calculate these numbers, casinos hire computer programmers and mathematicians to do the work. Because casino employees do not specialize in the field, they outsource the work to experts. The benefits of hiring an expert in this field are many.

Security in a casino begins on the casino floor, where employees monitor the games and patrons. Dealers, for instance, are focused on the game at hand and are unlikely to notice someone cheating, but table managers and pit bosses are trained to look for unusual behaviors. This information is recorded for later review. Security is so important that a casino uses computer chips to determine the payouts on the slots. While this may seem counterproductive, it is the most efficient way to prevent fraud in a casino.
