Prior to the digital age, cheating at casino establishments was a regular occurrence, and it is believed to have continued until as late as the 1990s. The earliest versions of the slot machine were particularly easy to manipulate thanks to their mechanical structure which could be affected by magnets, coins on strings or fake coins, for instance. An infamous fruit machine cheat, Tommy Glen Carmichael, used the fake coin trick to manipulate slots. The metal device that he used resembled a coin, and by inserting it into the coin slot he could trigger payouts without losing real cash. Even newer, electronic slot machines have been cleverly manipulated; an example being when a software programmer abused his position by programming an Atlantic City slot game to pay out following an exact sequence of coins entered into the coin slot. When a huge win was triggered, the employee – who should have been testing the software for bugs - was investigated and disciplined.
