Gold Bonanza Question for Ben

I’ve been looking through your material on games with which I’m unfamiliar.  In your Gold Bonanza video, you make the point that one should always read the description of the game, noting that it says, “Grand, Major, Minor, and Mini jackpots can be won randomly on any bought game.”  You interpret that to mean that one has the same chance of hitting the jackpot on a single spin regardless of the amount bet.  What strikes me as an alternative interpretation (more likely I think) is that this works like a mystery jackpot where the jackpot is triggered when the level crosses a randomly generated level.  Under this interpretation, your chance of hitting the jackpot pretty much scales with your bet size.  So, which interpretation is correct?

I bring this up for another reason as well.  I am curious about games like Frankenstein, where one needs to play at least $3/spin to be eligible for the top jackpot (obviously that’s a moonshot that doesn’t factor into playing decisions).  Does one have the same chance at hitting the jackpot on a single spin at the $3 level as one does at the $50 level?

In my opinion at least, one problem with the “Ben interpretation” is that it would seem to suggest that the RTP for a min bet player would actually be higher than the RTP for a max coin bettor.  If I were designing slot machines, I cannot imagine why I would design them that way.
