Gamblers who win a million dollars usually keep on playing and hope to win two million more, because it is their greed that drives them. This is a profitable strategy for the casino, since they can use the greed of other players to gain more money. However, the casino doesn’t necessarily have to cheat or change the settings of the games to benefit their bottom line. They rely on the irrational behavior of gamblers and the rules of the game in general to benefit itself.
During the 1990s, the casino began to use technology to supervise the games. Video cameras and computers were routinely used to monitor gaming activities. Another technology, known as “chip tracking”, enabled casinos to record every bet and monitor its progress minute by minute. Roulette wheels are regularly monitored and tested for statistical deviations. Some casinos have also begun to introduce enclosed versions of their games, which eliminate the need for dealers. Instead, players can simply push buttons to make their bets.
Although the casino is dependent on gambling to make a profit, it does not have to be the worst place to gamble. The house edge is used to determine the amount of money a patron can win, and variance is used to calculate how much cash the casino has to cover its expenses. The mathematicians and computer programmers who do this work are known as gaming mathematicians and analysts. Most casinos do not have in-house expertise in these fields, so they outsource the work to experts.
