Eight Biggest Casino Jackpot Payouts in the UK

Aside from the thrilling entertainment that playing the latest casino games offers, there is no denying that the most sought-after aspect of gambling is a significant windfall. Each year, more than an estimated 31.88 million British punters try their luck in search of a life-changing win. 

This win is elusive for many, as they either lose money or gain small wins. A lucky few, however, manage to clinch victory in a way that makes headlines, bagging wins with multiple figures. 

Below, we’ve found the UK’s eight biggest casino jackpot payouts. Each of these wins has changed the course of their respective punter’s lives and given them the financial freedom we all dream of. 

1. Mega Moolah Millions

The most significant win in UK history is easily that which occurred in 2015. British soldier Jon Heywood was relaxing on his PC after returning from Afghanistan and had chosen the legendary Mega Moolah slot by Microgaming to have some fun.

Placing a tiny £0.25 bet, the 26-year-old veteran hit the coveted progressive jackpot the game offers. Scoring a staggering £13.2 million, the soldier kept his win to himself, unsure whether or not he was dreaming. He even returned to work – reporting to duty without saying a word.

After coming to terms with his outstanding luck, however, Jon made his incredible win public. When asked what he would do with his windfall, he said he would use the money to help pay his father’s medical bills and treat his family to a well-deserved cruise. Not a bad start!

2. Mobile Luck

Mobile gambling is increasingly becoming punters’ favourite way to play. And it was accessing Mega Moolah using a mobile casino that an anonymous winner known only as D.P. struck it lucky in 2016, entering the Guinness World Record for the largest mobile slot win in history.

Playing using a newly registered account, the lucky winner searched for some of the best payouts in the UK and stumbled upon a promotion offered by a prominent casino. Offering the chance to win millions for a deposit of just £1, D.P. logged on using his iPad and began playing. 

With luck falling squarely on his side, the unknown player bagged a jackpot of £7.9 million – becoming an instant millionaire. Although he wasn’t the only winner – six other players also benefited from the casino’s promotion – he walked away with the lion’s share of the prize money.   

3. The Win of Gods

Known only as Neil from Aberdeen, this lucky player proved that fortune can fall on the novice just as much as on the experienced. Having never gambled online before, Neil decided to deposit £30 after seeing an advert for an online casino that piqued his interest. 

After playing just £4 of his deposited amount, Neil struck gold while playing NetEnt’s Hall of Gods. Landing a £6.3 million jackpot, Neil instantly thought something was amiss. Suspecting his friends and family of pranking him, he only believed his incredible luck after the casino called him to congratulate him on his win. Imagine getting a call like that!

4. Winning a Mega Fortune

Progressive jackpot slots are often known for turning the working class into millionaires. Mega Fortune by NetEnt is certainly well known for this. In 2016, the slot changed an anonymous player’s life after winning the £6.2 million jackpot from a small £1.25 bet. 

Believing the game had malfunctioned, the disbelieving player contacted the casino’s customer support for assistance. Only when the customer representative confirmed the win did the reality of their excellent fortune finally hit home, and the celebrations could begin.  

5. King of the Wins

Appearing in the libraries of multiple online casinos, the Jackpot King progressive slot system helps boost jackpot pools quickly, with multitudes of players contributing. The legendary King Kong is one of the most popular slots linked to the system.

Previously a mental health worker, Michael Clark was cautious in early January 2023, punting just £1.40 per wager. His efforts quickly paid off when he won £5.4 million – which surely made planning his upcoming wedding and installing a new stair lift for his grandma much easier. 

6. Giant Jackpot

One of the most common times for players to try their luck is after a long workday. This is precisely when an anonymous player decided to unwind by playing Playtech’s Jackpot Giant. Though unbeknownst to her at the time, she was ensuring she wouldn’t need to head to work the next day – or ever again.

Landing a £4.5 million jackpot, the lucky winner struck it big after just a few spins. After a local paper picked up on the story, it was revealed that she would have had to continue at her current job for at least 170 years to earn the same amount. 

7. Now and Then Riches

While many UK residents enjoy gambling regularly, some prefer to indulge in the pastime occasionally. A lucky winner fell into this category in 2015, preferring the thrill of gambling only at specific times. 

By choosing the right moment to play, the anonymous player proved that even those playing casually could have Lady Luck shine upon them. Playing the famous Mega Fortune game, the winner received a £3.6 million jackpot after wagering just £10. 

8. Anonymous Millionaire

Mega Moolah is notorious for paying high sums of money. After all, it is responsible for three of the eight highest jackpots in UK history. The third was a lucky win achieved by an anonymous player in 2019.

Betting the small amount of £6.50, the player hit a substantial progressive jackpot and took home £2.77 million – equating to a return of more than 426,000 times their initial stake. 

Additional Mention

While all of the wins above occurred while players enjoyed the convenience of online casinos, physical casinos are also known for paying out large sums. Sir Phillip Green, a well-known roulette enthusiast, won big while playing at the Les Ambassadeurs Club in London. 

Stating that he was enjoying a fantastic night at the tables, the retail tycoon scooped up an impressive £2 million. It is rumoured that during other visits to the casino, he gained a further £1 million in winnings – bringing his total haul to a generous £3 million. Those are indeed some fantastic nights!
