I just read some more articles about this case from 2014. I now understand it better. What these 5 gamblers did could not have been spotted by any standard AP techniques.  There was a bug in the program that had these keno machines paying out 5 times more than it was supposed to, but only if you put the “right denominations” into the machine. It’s hard to believe they figured out the “right denomination” by chance.  
This is why the gaming company, WMS, said these 5 won this money by “theft” and illegal activity. They obviously couldn’t prove their case, but both WMS and the casino strongly believe this is an “inside job”, meaning the person that wrote “the bug” in the code was somehow connected to these 5 gamblers.
What story makes most sense?  That five gamblers from Vegas happen to drive all the way to Illinois and by chance figured out “the right denomination” to put in these machines to trigger 5 times the payout, or they got an “inside tip”?
            
         
     
  Please link me to this article, I don't think you understand the facts or how this bug worked and you are misinterpreting certain things. I was told how it worked soon after it happen(I was keeping my eyes open for the machines in NV). I don't remember all the details, however, I don't recall it having to do with certain bill denominations, but rather certain machine denominations. And this kind of glitch/bug has been around for a while in more than one instance. So, it would stand to reason certain people would be  looking for and testing various sequences and combinations on newly installed games. I don't know much about software programming and coding.  I would think that other coders/programmers have an idea what kind of mistakes are made and what to look for when they want to find a vulnerability.
From my understanding the Double up bug from way back when was found yet again within the last few years here in Nevada in a popular gaming area.
 
     
 AxelWolf, I can't find the article I just read, and I don't know how to find it on my phone.  I'm sure there is a way.  The article clearly said it was the "right" demoninations that triggered the 5 times payout.  I did find this quote from a different article, which discussed the lawsuit the players filed against the casino:  “While [the players] had ascertained how to increase the amounts paid through the particular denominations they bet."
No one is disputing it was a "particular" amount bet that triggered the bug that gave them the high payout.  The question is how did they figure this out?  
I'll continue to look for that article and when I find it, I'll post the link.  I can't do that at work though since my work computer doesn't allow me to access this site, or any gambling site.  I'll have to do it at hone.  I can only access this site through my phone. 
Just type in some key words, like the gamblers names and Joliet and you'll find a lot of articles that discuss this case from different viewpoints.
