The scheme eventually unraveled when a state gaming control board agent noticed the high payoffs and began an investigation.
He got too greedy.
This is how many "emptiers" end.
This was not a TRUE "emptier" though, as it involved what is essentially a "fake screenshot" being presented to claim the jackpot.
I am suprised the CASINOS didn't catch on earlier because of the sudden burst of jackpot wins. It took a gaming board agent to notice something odd.
Perhaps this problem of "shoddy code" exists online more than they would have us believe, but like casinos where you have to be manually paid a big win, online casinos have an opportunity to audit payouts before they give the money out to the player.
No such luxury for UK Fruit Machine operators though
Fruit Machine "emptiers" really WERE down to glitches, and sequences of actions. No intervention of a technician required (except the one who refilled "PayRise" at Corley services on the M6 just after I had "done it", and gave me the chance to empty it TWICE in a single visit

)
The only successful proscecution in the UK for an "emptier" (that I know of) was against a pair of programmers who deliberately inseted an "emptier" into the code of a machine under development, and then conspired with others to profit from it after release.
The UK have recently brought in a new Gambling act, and Computer misuse laws. Either MAY enable charges to be brought for distribution and use of an "emptier", but gathering the evidence to a criminal court standard could be a problem, since these machines pay out automatically, rather than display a win to be paid by an attendant. Although an audit would reveal that an "emptier" exists, and had been used, they would not easily be able to trace who used it, and when.
Now, machines thought to be vulnerable are switched off or removed, and manufacturers issue warnings to operators whenever a glitch is discovered. Modern times means it takes only DAYS to shut down an exploit, whereas in the early 1990's, the "PayRise" glitch ran for MONTHS.
The companies responsible for these buggy Fruit Machines now provide software versions to some online casinos - I hope they are more careful with coding now
