By default the highest jackpot running is the one showing as a observer
Dude you've written it twice, I've understood you twice. I also knew this was true and had been told by a rep before. I just couldn't believe you'd admit it.
Extrapolate this out:
Imagine a Casino in a big gaming city like Vegas or AC. They have a Progressive Slot Machine. They have an added wrinkle where you can click a button instead of betting where you "observe" a slot pull. And the pull always hits the jackpot. What do you think that would do for business on that particular slot machine?
Okay, not a completely fair and accurate analogy, since you only show the highest CURRENT jackpot being played for, and not the highest possible that can be won. So use that then, the slot machine you hit "observe" and all the slot machines are wired together and the "observer" sees whoever just hit the biggest current jackpot. Would THAT be good for business?
I'd assume so, but I stopped paying any attention to the economics of slot machines probably before I turned 21 and could actually waste my money on them. So, I suppose, if EVERYONE on the floor is getting killed by the machines, the "observe" feature wouldn't be that enticing. But I know people (since when I played in Aurora the machines were right next to the poker tables) who I can pretty much guarantee would see that win, even if it wasn't super huge and they would chase it down to their last penny trying to hit it.
I'm not actually commenting on your strategy/operation actually, I'm merely playing devil's advocate suggesting that
casinos (which already kill you guys in revenue anyway) would likely love to have a "wrinkle" like this on any number of games.
