We're awaiting details on the big win, but our exclusive jackpot tracker recorded the win, which is the 61st we've picked up since we started following the prize a decade ago. The jackpot is smaller than the $5,730,619 average, but this is due to a player winning $3.5 million three weeks ago.
The Mega Moolah Mega grows with every spin of the reels and pays out randomly on any bet amount. The jackpot holds the record for all-time largest online prize, as an anonymous winner took home €18,915,721 at Grand Mondial.
We'll update readers as we learn more about the win.
