Absolutely, the spin outcomes on Mega Moolah are all thanks to the RNG. Every spin is its own thing, no matter how much you bet. But it's kind of an open secret that throwing down bigger bets does up your chances for the jackpot. It's no guarantee, and yeah, small bets can get lucky too. The developers keep the why’s and how’s under wraps, but it's all about keeping things fair since heftier bets mean more money for the jackpot.
Just remember, no matter how big the jackpot gets, don't lose your head. Playing smart with your money is key, jackpot shot or not.
