Bet with $35,000 in a bet just insane, he even won almost $950,000 by doing that.
Surely this guy will not gonna bet that high amount one time big time on a slot game. Probably his bank roll is above 500K to 1M USD to come up on that bet size. Sometimes this kind of whale gambler is just enjoying to burn big time money and I'm sure that he loss more the amount he win before he hit that jackpot. The probability of hitting that high multiplier is low though.
