How to Find Out the House Edge and Variance of a Casino


The house edge and variance are two of the most important statistics for any casino. They tell a casino’s hosts how much money it makes from a game and what its cash reserves are. These calculations are done by computer programmers and mathematicians who are called gaming analysts. Most casinos do not employ these specialists in-house, so they outsource these tasks to people with the appropriate experience. These experts can help a casino better determine its house edge and variance.

A casino may offer more than one type of game, such as roulette. Some casinos install catwalks in the ceiling above the casino floor, allowing surveillance personnel to see directly down into the casino’s gaming area. Another form of casino security is the use of surveillance cameras. One way glass and a camera are common security features at most casinos. Although they are not the most convenient security measures, these devices do help protect patrons and staff. However, they are not enough. A casino should employ multiple layers of security to ensure the safety of its customers and employees.

In addition to providing gaming equipment, a casino also offers entertainment and live entertainment. In the twentieth century, casinos have become more selective when it comes to who they let in. They tend to offer luxurious accommodations and amenities to attract the high rollers, which often spend thousands of dollars. Some casinos even have lavish stage shows and dramatic scenery, in addition to free drinks. These luxury amenities attract high rollers, but their high-roller status still allows them to profit handsomely.
