The Biggest Slot Machine Wins in History

By: Will ConningtonOctober 5, 2018

When I see a slot, the first thought that crosses my mind is – jackpot! Not that I have won many of those throughout my lifetime, and the ones I got weren’t really life-changing or anything… But still, this is an association deeply ingrained in the mind of any slot player worth their salt. The giddy anticipation for that CA-CHING sound is the reason we take to the field again and again, coins in hand – or, considering what year this is, an online balance ready for action! However, the truth is that not everybody would get the chance the hit the big jackpot. There would be little point in gambling if we were assured in our victory, after all. But how big is a jackpot exactly? It is worth it? Well, it’s time to find out! Let’s take a look at the biggest slot machine wins in the history of the game – and dream a little for our own big day.

Countdown of the 10 Biggest Slot Wins

Of course, you should keep in mind that judging the value of a win is quite hard – especially with exchange rates being fickle as they are. Still, we will be looking at pure numbers, starting our countdown with the ‘smallest’ prize in our list of the biggest slot machine jackpots and getting to the largest at the end of our article. Here is just of preview of the mind-boggling wins that we will have a look at.

10. $12.7 Million (£8 mln) on Your Niece’s Birthday

Everybody knows that Las Vegas is the place to be if you want to strike big, and this certainly proves true in our ranking. Sitting at tenth place we have an anonymous woman who was simply visiting her niece for her birthday at the Aria resort – not a bad way to celebrate, indeed! On the way to her room she decided to put $6 dollars in a nearby slot machine, and strange numbers started flashing everywhere!

We take a little pause here, because the slot was of the Megabucks series by IGT – get used to the name, because we will be seeing quite a lot of Megabucks in our rankings. Don’t mistake it with the Oregon lottery that has the same name, this is a famous brand of land-based slot machines introduced back in the 80s. They were among the first linked slots to be found at land-based casinos. As you know, this is the equivalent of the progressive games that can make you a slot millionaire at online casinos. Now, the Megabucks isn’t a good slot from an experienced player’s point of view, but when you hit the jackpot there – well, let’s just say that it feels like a win from the lottery.

The lucky aunt could not believe that she had won the jackpot with her 6-coin bet. Her niece actually had to explain to her that she would be pocketing $12,769,933 – almost £8 million at the time! This was basically the jackpot for the entire Nevada, and the overawed winner would go on to claim that she already had plans in place for it.

Paying the mortgage.

9. Over €11 million (£10 mln) on a Sleepless Night

Counting sheep to fall asleep isn’t always the brightest idea. A university student in Norway was up for a pleasant surprise when he decided to spin an online slot instead during his own sleepless night. He was a client of the Besson sports section, but since he had logged in at a very late hour, he decided to use up some of the free spins he had received from the online casino.

The student wanted to try out the Mega Fortune slot – if you’ve read our reviews, then you might know that this game is produced by the well-loved NetEnt studio and is considered one of the best progressive jackpot games out there. He probably thought he was dreaming – and with good reason, considering the ungodly hour! – when he found out he had won €11,736,228.

It is fair to say that the sudden windfall probably didn’t help with falling asleep on that particular night…

8. $21 Million (£12 mln) for a 92-Year-Old Veteran

Remember Las Vegas and the Megabucks slot? Well, here we go again!

This time around we have a true record-holder on our books. The probability of hitting the Megabucks jackpot is something like 1 in 10 million – so even Terry Pratchett’s famous one in a million long shot won’t help you here! However, a Las Vegas gambling veteran managed to beat the odds not once, but twice!

Elmer Sherwin – who apparently does not hunt ‘wabbits’ – had his first lucky break when he was traveling the country with his wife and stopped in Las Vegas to visit family. The World War II veteran had been a fan of gambling for decades, so he took to playing slots every week – and managed to win $4.6 million on the Megabucks! The sum might seem paltry, not significant enough to get into our list of the biggest slot wins, but it was something else for the time, and Elmer used it to fulfil his life-long dream and travel around the world.

However, he never gave up on slots, and particularly on the Megabucks. Even though money no longer interested him at this age (he was already eight decades old when he won the first jackpot), the man wanted to earn the fame of beating the slot twice. To everyone’s astonishment, his diligence actually paid off in 2005. 92-year-old Elmer won the jackpot again – and this time around it was a whopping $21,147,947! Elmer donated a large portion of his winnings to aid victims of Hurricane Katrina and claimed that he isn’t sure on which slot he would seek his third big win. However, two jackpots were enough of an achievement – the gambling veteran passed away in 2007, having lived through the dream of many.

7. Another $21 million (£13 mln) at Caesar’s Palace

21 seems to be a magic number – another Megabucks jackpot almost equal to Elmer’s second win was claimed at the famous Caesar casino in Las Vegas. Caesar’s Palace has become an important part from Las Vegas folklore. The famous fountains in front of the casino were once the sight of a failed stunt by famous US daredevil Evel Knievel.

The casino has also become the site of many spectacular gambling wins. Slot jackpots are represented by a 1999 lucky spin of an anonymous business consultant. The lucky sod bet only $10 and claimed a prize worth $21,346,952. Little else is known about this particular occasion since the 49-year-old man wisely elected to remain anonymous, but there are unconfirmed claims that he actually won the jackpot with his very first spin.


6. $22 Million for Johаnnа

Another grand Megabucks jackpot fell in 2002 and was claimed by 74-year-old Johanna Huendl. As you can well see, the lucky winner had no intention whatsoever of remaining anonymous this time around. Considered the fourth greatest jackpot in the entire history of Las Vegas – it was claimed en route to a breakfast table.

It seems that Johanna was spending her vacation in Nevada and decided to bet several hundred dollars on a slot she happened to walk by early in the morning. When it started flashing, the woman thought she had won $2 million – well, bad eyesight can be forgiven at her age! Can you imagine what her reaction was when she learned that she had missed one more digit? Her jackpot was actually worth $22,618,156 – almost £16 million in 2002!

She probably ended up skipping breakfast, too.

5. Mega Fortune Worth $24 Million (£14.9 mln) for a 25 Cent Bet

Jackpots can be crazy sometimes. While playing at a Scandinavian online casino, a 40-year-old Finnish man made a 25-cent bet and won over $24 million. The poker face of the experienced card player sure fell apart then – he claims that he laughed and cried at the same time.

The slot he played would be familiar to you – it was Mega Fortune again. If you are noticing a trend, then you are not wrong. If we are talking about the biggest slot machine jackpots, then certain slots usually hold all the records. Of course, you should keep in mind that the record wins have no bearing on the overall profits you can make from a slot – you need to keep an eye on the RTP (Return to Player) rate for that.

As for our Finnish player, he got lucky with a Mega Fortune bonus feature, so the size of his bet was not that important – though it does make for a good headline. Little is known about the man, except for the fact that he was actually a poker player. More’s the luck that he decided to try out other games as well. Might make him reconsider his gambling strategy, eh?

4. The Mega Moolah Record of £13.2 Million

Online slots generally measure up quite well when compared to land-based ones and offer you quite a few pros. When it comes to jackpots, the good old Mega Moolah is the first association that comes to mind if you are following the happenings at online casinos.

The traditional Microgaming slot was all over the news back in 2012, when a British soldier from Cheshire managed to hit the Mega jackpot. There was a little bit of a frenzy back then, because the jackpot had been growing steadily for quite a while, and more and more players were starting to take notice.

In the end, it was 26-years old Jonathon who managed to crack it. There was much cheer on all sides, even at the casino who were more than happy to make the history books. Mega Moolah actually has not one, but four jackpots on offer at all time, but their sizes are quite different. It must be quite the experience to expect the M-ini or the M-inor jackpot, and to end up with the M-ega one – for Jonathon it meant that he finally got the chance to drive a Bentley!

If you’ve been following the numbers, you might end up wondering why we’ve ranked this jackpot in fourth place. Well, we did mention the fickle exchange rates. When it was claimed, the jackpot was worth over 17 Million – in euro. This means that it still holds the title for a biggest online slot jackpot to this day, beating the Mega Fortune one.

3. The Wrong Bet Nets You 27.5 Million Dollars!

We have to be careful when we are placing our wagers, but a mistake at the right time could turn out to be quite profitable. This was the case with a retired flight attendant from Las Vegas, who was visiting the Palace Station and thought she was depositing $100 at a Megabucks – but put in $300 instead!

Before she had the chance to rue her mistake, the woman was rewarded with a jackpot worth a little over $27.5 Million – that was more than £16 million at the time! We’re getting into top figures now, as this is currently the third largest jackpot ever won in Las Vegas. As for the flight attendant – who knows, perhaps she bought a private jet of her own? She already had $700,000 at her name from a previous spin at a Wheel of Fortune slot.

2. The $35 Million Source of the Megabucks Curse

But not all of the biggest slot wins make for a happy tale. If you listen to the Urban Legends in Nevada, you might even hear that Megabucks jackpot winners are cursed. As you have seen from our list, there is little proof about the existence of such a curse – but the tale does have a rather unpleasant origin.

At the turn of the new millennium, a cocktail waitress broke all records at the Desert Inn casino. Cynthia Jay-Brennan won 34.9 Million Dollars at the high-rolling casino, one of the highest Megabucks jackpots ever paid. At the time, her prize was worth over 21 Million Pounds!

However, just a month and a half later Cynthia got involved in a very tragic accident. While driving with her sister, her car got hit by a drunk driver. Her sister died on the spot, while Cynthia was left in a coma, and would wake up paralyzed from the chest down. Even though she and her husband have managed to find a modicum of happiness even after the horrible accident, she claims that she would happily give all the money back to get her old life back.

1. The $39 Million Record!

$39,719,826. That’s a lot of digits.

To put this in a perspective, with this kind of cash you could buy your own private jet, an entire beach, Taylor Swift’s apartment, or more than 1,000,000 acres of land on the Moon (courtesy of, and not considered a sound investment).

This jackpot was won on the 21st of March, at the famous Excalibur Casino in Las Vegas. The slot was – yeah, you guessed it! – Megabucks. The winner was – well, he elected to stay anonymous. Wonder why, with almost $40 mils on his name. The only known things about him are that he was a 25-year-old software engineer from Los Angeles, and that he bet only $100 before winning the big one. So, if you know any 40-year-old men from Los Angeles, you should definitely check whether they aren’t hiding a vast fortune from you!

To this day, the $39 million jackpot holds the record for a slot win in Las Vegas and the world, so it tops our list of the biggest slot machine wins ever. When will it be beaten? Well, that’s anybody’s guess, but here’s to hoping!

And an Honorary Mention…

Well, Katrina Bookman does deserve an honorary mention at least. The unlucky woman was all over the news just a few years ago, when she won the mind-boggling £35 Million on a Sphinx slot machine – if you’re interested, our record-breaking software engineer’s jackpot was worth just a little over £25 million!

However, to her dismay Katrina found out that instead of a jackpot, she had won… jack squat! There had been a slot malfunction; in fact, the maximum possible win at the game was supposed to sit at just $3,500! Even though court cases continue to this day, Katrina is still waiting for her record jackpot, and odds are that she will have to keep waiting for quite a while yet!
