Jackpots; the one thing every gambler tends to dream about.

Earning a massive jackpot win in any of the world’s best online casinos could signify that your bank account will have a different look for the rest of your life. Small bets and big bets can earn you large jackpots, but one thing’s for sure: you’re going to need a ton of luck if you’re chasing one of those multi-million wins with small bets.

Is it impossible to win such massive sums of money, though? Not at all. Some people have managed to earn over €10,000,000 with bets lower than €0.25. What makes that you can’t be one of the lucky ones to share such luck?! Here, you’ll find the 10 biggest online casino wins ever.

These wins have changed the lives of the lucky few that managed to get them, and the games rank among the highest-paying jackpot games of all time - as well as some of the best bitcoin jackpot slots that you can play!

The Mega Moolah jackpot has been won the most in the classic game, but it has also been won in other versions of the game - learn more about the game and find out where you can play it here.

10. The Finnish Player Who Won €8,635,872

Back in 2012, a man from Finland decided to try his luck in one of NetEnt’s oldest online slots: Arabian Nights. Even though this game is not particularly known as one of the highest-paying online casino jackpot slots that the company has developed, it still has the potential to win players some absolutely ludicrous rewards.

This was the case from this anonymous man from Finland, who netted just over €8.5 million with a single wager. By the time that we’re writing this article, the game has already lost a lot of its appeal. However, this legendary win still remains as one of the biggest sums of cash ever paid in a NetEnt game. Jackpot hunters know very well of Arabian Nights, even though many are just focusing on Mega Fortune and Mega Moolah in today’s casino scene.

However, there was once a time in which an anonymous played tried their luck in an attempt to see if they could best the game’s algorithm.
