Technology and the Casino Business

The most important thing for a casino is to have an expectation of winning. This expectation is the same whether the casino is playing blackjack or baccarat. The house edge and variance of each game is known to casinos and helps them calculate how much cash they need for the day. Gaming mathematicians and computer programmers are responsible for this work. Most casinos do not have in-house experts in this area, so they hire experts to do it for them.


In the early 1990s, casinos began using computers and video cameras to monitor and control the games. “Chipp tracking” involves betting chips with built-in microcircuitry that allows casinos to check and record wagers minute by minute. Roulette wheels are also regularly monitored for statistical deviations. Most games are available in enclosed forms that require players to push buttons instead of interacting with a dealer. The casino is responsible for these changes, but it is still possible for a player to win without cheating or breaking any rules.

Technology is a crucial element in the casino business. In the 1990s, casinos started implementing technology in their operations. The use of video cameras, computers, and other sophisticated equipment is now routine, and chips with built-in microcircuitry allow casinos to monitor wagers minute by minute. Similarly, roulette wheels are regularly monitored for statistical deviations to keep tabs on the outcome of the game. Finally, enclosed versions of games no longer need dealers and can be bet by pushing a button.
