The most logical and fair solution would be that chance for hitting the jackpot is proportional to the bet size. (Ie. liniar function).
This way payout% is the same for all bet-sizes and small bets can win the big jackpot also. I like this the most.
Another solution is that you only win a part of the jackpot. (Ie a 1$ bet would win 20% of the jackpot where as a 5$ bet would win 100%). This is also a fair solution and chance for hitting the jackpot is now the same for everyone (though jackpot size differs).
Unfortunately neighter of the cases seem to apply at
RTG casinos.
You could argue that due to the huge house edge at slots it would be fair that high rollers faces a smaller house egde. And this is also the case in Vegas. But this is for
different slots. Ie. playing quarter slots compared to $ slots.
When it happens for the same slots I feel low rollers get cheated but
only because
RTG do not tell players that. (Nor publish any payout% records for that matter).
