Biggest Online Slots Wins Of All Time – 2021 Edition

During Thanksgiving 2021, an online casino player in the US broke the domestic record for biggest online slot win on the MGM Grand Millions slot, taking home a cool $3.5 million. But, believe it or not, that’s not even among the biggest online slot wins of all time. Below are the top five jackpots ever won at an online casino.

5. $11.6 Million On Mega Moolah

Imagine casually betting just $1.50 on your mobile device, only to land a $11.6 million jackpot. Well, that’s exactly what happened to D.P. of the UK, who scored a massive mobile payout playing the Mega Moolah online slot.

The lesson here, and throughout the rest of this article, is simple: you don’t have to bet big to walk away a big winner.

4. $17.3 Million On Arabian Knights

This one came in 2011, when an online casino player out of Norway landed a $17.3 million jackpot on the Arabian Knights online slot. The online casino, Betsson, is not available in the US, but the game is made by NetEnt, which does power some online casinos in the US. While neither Golden Nugget nor BetMGM houses Arabian Knights, it may be accessible to American players somewhere.

3. $19.9 Million On Mega Moolah

If you had trouble imagining a $1.50 bet paying out in the millions, try this one out for size: Jon Heywood of the UK placed a $0.25 stake and walked away with a $19.9 million jackpot on the Mega Moolah slot. And, yes, Mega Moolah boasts three of the top five biggest online slots wins of all time.

2. $22.4 Million On Mega Moolah

Based purely on the number of winners, Mega Moolah seems to be the online casino that can pay out the most. It’s a shame that US players don’t have access to it, but as online casino gaming grows in popularity across the US, it very well might.

Let’s hope so because, as recently as September 2018, a player hit the biggest jackpot in Mega Moolah’s history: $22.4 million. Perhaps even more amazingly, they won after fewer than 50 spins – and the winning bet was a mere $0.75 per spin.

1. $24 Million On Mega Fortune

The title for the biggest online slot win of all time goes to a poker player in Finland, who tried their luck on the Mega Fortune online slot with just a $0.25 bet per spin. With a $24 million win, you might think he retired from online poker. If so, you don’t know online poker players.
