The world’s most popular progressive jackpot slot online, Mega Moolah, is not only reaching another potentially record-breaking win – the Microgaming machine literally passed the €3.8 million on the day of writing (October 8) – but one casino outlet is actually offering a bonus of at least €300,000 on top of *that*.

In a drive to show off their wares in the mobile casino sphere, Jackpot City has announced that should the lucky winner of the next huge Mega Moolah payout be playing at the Jackpot City mobile online casino, he/she will take home an additional €100,000 per €1 million won on the lucky spin. With that jackpot approaching a cool €4 mil, the nouveau riche will become richer!

Mega Moolah was one of the very first progressive jackpot slots to be launched online and since the late 1990s has paid off over $3 million four times to date. The all-time record for largest progressive jackpot won on an online slot was set by Mega Moolah in 2009, breaking its own two-year mark when a player hit a €6.37 million prize. The last such payout from the slot was awarded last year, as a winner took $4.1 million on the game at Spin Palace Casino.
