Top 10 largest jackpot wins at online casinos

Especially the mega jackpot games that have gained popularity among lottery players have distributed billions in winnings to players over the years. We have listed the ten largest jackpots in online casino history.

The so-called progressive jackpot slots have achieved a cult-like popularity among players. This is not surprising, as at their best, the winnings can reach tens of millions of euros. One game has clearly stood out in history as a millionaire maker, as a staggering 16 of the world's 20 largest jackpots have been won in the Mega Moolah game. Microgaming has also dominated this segment significantly.

In these jackpot games, the mechanics work such that a small portion of each bet is set aside directly into a common growing prize pool. This mega jackpot is triggered randomly, and the lucky player receives the amount collected in the pot at the moment they play their winning spin. Some online casinos also offer free spins or non sticky bonuses, which can help players hunt for these pots themselves.

1. WowPot - €42,149,180 in 2023

The history books were rewritten at the end of 2023 when the previous world record was more than doubled. An anonymous player managed to hit the jackpot at an unnamed casino and claimed an incredible over €40 million!

2. Mega Moolah €19,429,358 in 2021

The second largest win at the moment was, of course, won in Mega Moolah. Measured in euros, a €19.4 million pot went to an unknown player in Belgium in April 2021. Quite a hefty sum, but it still fell a bit short of the magical €20 million mark.

3. Mega Moolah €18,915,721 in 2018

The previous record was seen in September 2018 when an unknown player struck gold with a pot of nearly €19 million. Their nationality is still unknown, but winning the pot from Mega Moolah in euros suggests that the player likely resides in one of the eurozone countries.

4. Mega Moolah $20,057,734 in 2019

Once again, this particular game delivered a massive payout in January 2019. At that time, a lucky Canadian player broke the "20 million" milestone, although in their case, the win was paid in Canadian dollars. At the then exchange rate, this amounted to about €18.5 million.

5. Mega Fortune €17,860,868 in 2013

And now, ladies and gentlemen, it's time to warm up the fountains a bit and take off some clothes, as the fourth largest online casino win in history was played in Finland! A performance worthy of a town celebration was seen at an Åland Islands-based gaming company's online casino in January 2013 when a lucky player claimed a whopping €17.9 million jackpot.

This incredible pot is still the world record in that game, namely Mega Fortune launched by NetEnt. This is also the only jackpot that remains in the top 20 largest online casino wins ever played in this or any of NetEnt's games. Well done Finland, well done Åland Islands! No one can take this away from us.

6. WowPot Mega £15,183,085 in 2021

A little variation from the dominance of Moolah was recently seen. In April 2021, Microgaming's other major jackpot family, WowPot, produced its first super-sized jackpot. An extremely lucky British player took home £15 million, which is about €17 million.

7. Mega Moolah £13,212,882 in 2015

After a brief pause, we return to the familiar territory of Mega Moolah, back in 2015. At that time, another British player struck gold. A man named Jon Heywood won an impressive £13 million and some change, which at that time converted to over €15.5 million.

8. Mega Moolah $16,495,060 in 2020

Canada has seen some very large wins, and so it did in April 2020. At that time, the familiar game coughed up nearly $16.5 million Canadian dollars. In euros, the win amounts to about €15 million. So, a pretty good chunk left for the promised land of maple syrup.

9. Mega Moolah €14,679,069 in 2020

The wonderfully symmetrical year 2020 was also tough in the world of online casinos, as several large jackpots were won that year. One such win went to our western neighbor, Sweden, in August of the same year. It was a great time to enjoy the crayfish party snaps when over €14.6 million dropped into their lap. The story does not explain why it was euros and not crowns.

10. Mega Moolah $13,617,374 in 2020

And once we got going, we just kept going. The year 2020 was historic in that it saw more and larger wins in Mega Moolah than ever before in a calendar year. A staggering total of over €100 million was distributed, of which this unknown player claimed their share in May 2020.
