On June 4, 2021, a player from Estonia hit the Mega Jackpot on the Mega Moolah slot machine. This progressive jackpot game pays the biggest casino jackpots on the internet.

Last month’s winner took home €6,597,136.10 (CA$9.73 m), making it the second giant jackpot Mega Moolah jackpot in 2021. The previous win, on April 27, came in at €19,430,723 (CA$28.59 m). This crazy pot, won by a European, is the world record for the largest bank won at an online casino.

Last month’s winner is a member of the Optibet.com platform. Optibet is an online betting site reserved for players from Lithuania, Latvia, Estonia, Malta, Sweden and Curacao. Bettors have access to a variety of casino games via the casino’s catalog. It’s rare for large slot machine wins to occur at sports betting sites, but anything can happen when luck strikes. Unfortunately, we don’t know more about the June 4, 2021 winner as they prefer to remain anonymous. Indeed, most players don’t want to make themselves known when they become millionaires overnight.

Other Mega Moolah wins

Apart from the 1st prize of the game dishing out millions only to the luckiest players, players win the slot’s 2nd prize almost every day. Every week players manage to land pots of over $10,000, and sometimes even over $100,000. When you trigger the game’s bonus wheel, there are 20 segments marked with the four progressive jackpots. The Mega Jackpot segment is the most coveted, but the Major still pays well. As for the other two Mega Moolah pots, the Mini (+10) and the Minor (+100), aren’t anywhere near as profitable.


Microgaming CEO John Coleman and Optibet website manager Chris Davis have spoken about the jackpot won on June 4, 2021.

I am delighted to see another big jackpot won shortly after the 19.4 million Mega Moolah prize won in April 2021. My congratulations go to Optibet and the jackpot winner. This is another big milestone for Microgaming, with the Estonian winning being the 100th millionaire in our online slots network.
John Coleman, CEO of Microgaming.
