How Technology Is Used in Casinos

The casino’s house edge is its mathematical expectation of winning on every game. Since players rarely win more than the casino is willing to spend, a winning streak will keep them from leaving the casino. A major benefit of casinos is that they are not subject to state antigambling laws. Also, their lack of clocks and windows prevent them from knowing the time. A common inducement is free alcohol, cigarettes, and free drinks. However, players are advised to stay away from these promotions, as they can make them lose money in the long run.


Technology is increasingly used in casinos to make games more secure. Video cameras and computers routinely monitor game play. “Chipper tracking” involves betting chips with built-in microcircuitry. This allows casinos to monitor the amount of money a player has wagered minute-to-minute. Roulette wheels are also monitored to ensure that they do not deviate from statistical norms. Enclosed versions of many games also allow players to place their bets by pressing buttons.

In the 21st century, casinos began using technology. Computers and video cameras are routinely used to oversee games. Casinos also employ the use of “chip tracking” technology, in which bets are tracked minute by minute. Statistical deviations are regularly monitored on roulette wheels, as well as on roulette tables. This type of gaming is often the most popular in Europe, with some countries allowing casino gambling clubs to be open without the need for a dealer.
