Not to hijack the thread, but I wonder how difficult it would be for a really, really sharp coder to get hired on by a slot machine company like IGT and install a secret program that only he or someone who knows about it can take advantage of?

Sort of like Ronald Dale Harris, except instead of working for the Nevada Gaming Commission he'd work for the mfr.:see -- https://www.gamblingsites.com/info/f...s-reid-mcneal/

I wonder what IGT and other mfr's do to prevent employees from doing such a thing?

I mean, you can't watch a guy ALL the time...
