What does ‘best payout’ mean for casinos?

Now the trade off with these progressive jackpots is that the RTP is much lower than you standard slots and popular progressive jackpots like Mega Moolah, a slot with the famously highest paid out jackpot prize, only has an RTP of around 84%. Any wagers under that amount will just operate on the standard slot rules of the base game and will not enter you in with a chance for the jackpot.
