In order to make money, casinos must know the house edge, also called variance, of each game. This number gives them an idea of how much money they can make and keep in cash reserves. This work is usually done by computer programmers and mathematicians. Most casinos do not have in-house expertise in this area, so they hire experts in the field. Regardless, they should have at least one expert on staff to ensure that their games play fairly.
The biggest advantage of downloading software to play at an online casino is the speed. Since download-based casinos are able to run faster than web-based casinos, they are a great choice for players. They also cache graphics and sound programs so that they are easy to access in the future. However, the initial download can be time-consuming, and it is possible that it contains malware. This is why a casino’s safety is an important issue.
Casinos also use technology to monitor their games. In the 1990s, casinos began using video cameras and computers to monitor game play. This technology has improved the accuracy of casino-related information. “ChiP tracking” involves betting chips with built-in microcircuitry, which allows casinos to track the number of bets minute-by-minute. Roulette wheels are also regularly monitored for statistical deviations. Some casinos have even created enclosed versions of their games, which do not require dealers. The players simply push buttons to make a bet.
