Man Arrested For Exploiting Error In Slot Machines

"A man awaiting trial in Pennsylvania was arrested by Federal agents on Jan. 4, and accused of exploiting a software 'glitch' within slot machines in order to win payouts. The exploit may have allowed the man to obtain more than a million dollars from casinos in Pennsylvania and Nevada, and officials say they are investigating to see if he used the method elsewhere. The accused stated that 'I'm being arrested federally for winning on a slot machine. Let everybody see the surveillance tapes. I pressed buttons on the machine on the casino. That's all I did.' Apparently, slot machine software errors are fairly common. The lesson here seems to be that casinos can deny you a slot machine win any time they wish by claiming software errors, and if you find an error that you can exploit, you may find yourself facing Federal charges for doing so."

I have heard stories about people spotting patterns in double up features (red/black) and taking advantage of it.

The evidence of the FBI in support of these charges is going to be really interesting, I think...

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:D

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:p)

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;)

FWIW, I believe this was on video poker and it was a well known glitch that was discovered some years ago pertaining to changing denominations during a double up.

Casinos were advised to disable the double up feature some time ago on the affected software.
