Top 10 Biggest Slot Wins Ever

The biggest slot wins ever eclipse anything you may have won with a few free spins online. Life-changing sums of cash have been won on the world’s largest progressives. And it’s not just Las Vegas that has seen the biggest slots wins.

In recent years, the biggest slot machine wins ever have come online. As more people than ever play progressive online or via mobile, the jackpots get bigger and bigger. 

We have rounded up 10 of the highest slot wins of all time. Why not check out our best online casinos and see if you can match these eye-watering jackpots?

10. $20,062,600 (Jon Heywood) – Mega Moolah, Online 

In 2015, a British former soldier called Jon Heywood secured his pension with an incredible £13.2m win on Mega Moolah. 

Microgaming’s slot is among the most popular progressive jackpot slots of all time. And the longer the jackpot went unclaimed, the larger it got. 

Since then, Microgaming has sold its slots calalog to Games Global. You can now play a range of Games Global progressives at the best online casinos for real money. 

Why not check out our High Roller Casino review to see why it’s the best site for Mega Moolah slots? High Roller spreads 15+ Mega Moolah variants with linked jackpots. You can even try the classic version of Mega Moolah for real money. 

9. $21.1 Million (Elmer Sherwin) – Megabucks, Cannery Casino

Elmer Sherwin secured not one, but two of the biggest slots wins ever – both coming in Nevada. In 1989, Sherwin won $4.6m at the Mirage. However, he surpassed that by winning a $21.1m slots jackpot at Cannery Casino in 2005. 

They say lightning doesn’t strike twice, but Sherwin is proof that it does. Taking home one of the highest slot machine payouts ever is one thing. But the odds of hitting two gigantic slots jackpots aren’t even worth calculating.

Who knows? Maybe Elmer likes to play hot drop jackpots, which tell you when they have to drop. Ignition Casino offers plenty of chances to win when they do drop. 

Check out our Ignition Casino review to see why we rate the site’s Hot Drop Jackpots so highly. You can also open an account and claim a welcome bonus worth up to $5,555. 

8. $21.3 Million (Anon) – Megabucks, Caesars Palace

In 1999, a 49-year-old business consultant from Illinois wagered just $10 on the Megabucks slot at Caesars. Astonishingly, he ended up leaving the Palace $21.3 million richer. 

Nothing really comes close to Megabucks online. However, we recommend looking at OnlineCasinoGames for its range of 6-figure progressives. The casino spreads Aztec’s Millions, a jackpot slot that regularly passes $1m before being triggered. 

Plus, you can enjoy many top online casino games at this best-rated gambling site. You won’t win a life-changing sum of cash, but it’s all added to the bankroll for bigger spins later.  

7. $22.5 Million (TrainWrecksTV) – Might of Ra, Online 

Tyler Niknam, better known as TrainwrecksTV, is a Twitch legend for his gaming and high-stakes gambling videos. 

In 2020, TrainWrecksTV went on a heater, bagging $8m slot wins and massive payouts on the roulette table. However, the $22.5m jackpot TrainWrecksTV won on Might of Ra surpassed anything the online phenom had achieved thus far. 

It’s worth mentioning that he was playing $1,000 per spin. You’ll find that out of all the big wins on slot machines, this one was the highest wager.

You can watch the YouTube highlights of how TrainWrecksTV won his life-changing jackpot. Alternatively, sign up to one of our top-rated online casinos and give the progressives a go yourself. 

We recommend SlotsandCasino for its excellent online slots and jackpot games. The casino boasts 50+ linked jackpot games, including Wheel Big Winner Millionaires Life.

6. $22.6 Million (Johanna Heundl) – Megabucks, Bally’s Casino

The Megabucks slot has been churning out multi-million jackpots since it was launched by IGT in 1986. Bally’s Casino in Las Vegas had its first Megabucks winner in 2002 when Johanna Heundl won $22.6m on the slot. 

Plus, Heundl was celebrating her 74^th birthday when she won one of the biggest slot machine wins ever. That’s not a bad way to spend your birthday. 

After spending $100 without success, the retired Californian inserted a second $100 bill into the machine. With only $30 left, she hit both the primary and secondary jackpot – claiming a colossal $22,618,156.67.

The wheel of fortune format has been adopted by the best big win casinos over the years. Sign up to Sloto’Cash Casino to find a range of wheel bonus slots, including Santa’s Reel Wheel. Sloto’Cash also provides an interesting variety of jackpot slots including Jackpot Cleopatra’s Gold Deluxe. 

5. $23.5 Million (Anon) – Megabucks, Grand Mondial Casino

The Megabucks slot is one of the most iconic machines in history. If you’re looking for a big win in slot machines, there’s a good chance it’ll be with this game.

There have been several massive jackpots from this game, such as the one from 2018. An anonymous gambler at the Grand Mondial Casino won an incredible $23.5 million.

It’s probably in their best interest to remain anonymous anyways. As you can see, it’s pretty common for one of these lucky winners to remain out of the spotlight. There isn’t much good that can come out of revealing your identity, but there’s a whole lot of bad.

It’s tough to make an argument against this slot machine, but if any other game has a chance, it’s Mega Moolah. Check out High Roller Casino for its unrivalled selection of Mega Moolah slots and variants. 

4. $24 million (Anonymous) – Mega Fortune, Online 

NetEnt’s Mega Fortune slot was launched in 2009 and quickly became one of the hottest online progressives. It was repeatedly responsible for some of the biggest slots wins ever recorded online. 

In 2013, an anonymous Finnish gambler won €17.8m ($24m) on the Mega Fortune global jackpot. Believe it or not, all it took was a single $0.25 spin to secure one of the biggest online slot machine wins ever.

Can you imagine what would happen if you wagered a quarter and came away with $24 million? It’s a good example that big wins on slot machines don’t always require a heavy stake.

You can even skip land-based casinos and try winning big by playing at the best offshore slots around. Check out Bovada for its excellent supply of progressives and a great welcome bonus to boot. 

3. $27.5 Million (anonymous) – Megabucks, Station Resort

Megabucks struck again in 1998 to record another of the biggest slot machine wins ever. A retired airline worker bagged $27.5m playing the slot with a $300 bankroll. The woman was about to quit before hitting it lucky on her third wager.

Incredibly, the lucky lady had previously won $680,000 playing in the Station Resort a few months earlier. Her second massive win ensured a healthy pension with her and her husband and a massive tip for the casino staff. 

Megabucks isn’t available at our top-rated online casinos. However, you can follow in the footsteps of TrainWrecksTV by trying out progressives at any of our recommended sites. 

Why don’t you read our review of DuckyLuck Casino to see why it’s the #1 place for jackpot slots? The casino supplies 65+ progressive slots including Reels & Wheels XL. It’s just like playing Megabucks on your mobile phone or PC. 

2. $34.9 Million (Cynthia Jay-Brennan) – Megabucks, Desert Inn Casino

In 2000, cocktail waitress Cynthia Jay-Brennan decided to swing by the Desert Inn in Nevada after a work shift. After only a handful of $3 spins on Megabucks, she struck those famous matching symbols. In doing so, Jay-Brennan scooped one of the biggest slot machine wins ever.

Sadly, just a few months later, Jay-Brennan was left paralyzed after a tragic car accident and lost her sister. Since then, Jay-Brennan has donated a large portion of her winnings to charities that aid people with disabilities.

1. $39.7 Million (anonymous) – Megabucks, Excalibur Casino

So, what is the biggest slot machine win of all time? And what is the most money won on a slot machine? Stand up… Mr. Anonymous.

The biggest casino jackpot ever won happened back in 2003. A 25-year-old software engineer bagged nearly $40 million on IGT’s Megabucks slot at the iconic Excalibur Casino. 

The tech geek wagered just $100 to lock in the $39.7 million jackpot, sealing the biggest slot win ever. The $39.7m jackpot is yet to be beaten. 

However, a lucky player at Excalibur won $12.3m playing Megabucks Triple Red Hot Sevens in 2023. The win wasn’t quite big enough to make it onto our list of the biggest slot machine wins ever.

The best Hot Drop Jackpots let the casino do the hard work for you. Online casinos release jackpots throughout the day – and when they drop, they MUST drop.
