The biggest slot jackpots won in the UK

If you walk into your local pub and decide to play the in-house fruit machine – guess how much you can win? That’s right, a mere £100 jackpot + repeat chance. For the pleasure of working towards this somewhat uninspiring jackpot prize, you’ll need to play at a minimum stake of 30p per spin.

At the other end of the slot machine spectrum, did you know that online individual slot titles pay prizes of £1 million+ on almost a weekly basis? In fact, the biggest UK casino slot wins to date was won by Jonathan Heywood of Crewe. At the tender age of 26, the lucky punter won a remarkable £13,209,300 on the hugely popular progressive jackpot slot Mega Moolah

With that being said, all it takes is a single spin to land a multi-million-pound jackpot in the online space. If chasing that life-changing amount of money is something you’re interested in exploring further, be sure to read our comprehensive guide. 

Within it, we cover everything from the biggest UK casino slot wins of all time, what slot titles they were won on, what you need to look for when choosing a jackpot slot, and more. By the end of reading our guide from start to finish, you’ll have all of the required tools to go and target that multi-million-pound jackpot!

UK casino slot wins: The biggest of all time?

First and foremost, it is important to note that not all UK casino slot wins are published publicly. By this, we mean individual jackpot winners have the right to remain anonymous, much in the same way as UK National Lottery winners are not required to reveal their identity. 

With that being said, the casino will still publish the size of the win on their platform, as this acts as an excellent piece of promotional material. Nevertheless, for the purpose of our list, we have decided to discuss some of the most lucrative casino slot jackpots won in the UK that can be matched, or loosely matched to the specific player. 

Let’s start with the big one – Jonathan Heywood and his £13 million+ win! 

  1. Jonathan Heywood – £13,209,300 – Mega Moolah

As we noted at the start of our article, the largest UK casino slot win of all time is still held by Jonathan Heywood of Crewe. At the time of the win, Jonathan was serving in the British Armed Forces, subsequently completing tours in Afghanistan. 

As per the BBC report at the time, Mr Heywood – who netted the jackpot in October 2015,  did not reveal his win for three days. Moreover, the individual still turned up for duty the very next day! 

Heywood was quoted as saying “I couldn’t believe that I’d won all this money at the time – and it still hasn’t sunk in. It’s amazing. “The first thing I will l spend it on is the best possible medical treatment for my dad.”

The best thing about the win – which was played on the Mega Moolah progressive slot title, was that the jackpot was landed on a spin of just 25p. To put that into perspective, the minimum amount that you can play on a pub fruit machine now is 30p, even though the largest prize available is £100! 

As such, Jonathan’s success illustrates that you don’t need to bet big to win a life-changing amount of money. On the contrary, at just 25p per spin, the opportunity to land a progressive jackpot is open to most.

  1. Neil – £6.3 million – Hall of Gods

Back in 2017, an extremely lucky player from Aberdeen – known only as ‘Neil’, won a staggering jackpot of just over £6.3 million. The reason that this particular win makes our number two spot is that Neil was an absolute newbie in the online slots space. In fact, the individual deposited just £30 into his newly opened Casumo account. In doing so, Neil headed straight to the jackpot slots department and opted for Hall of Gods. 

For those unaware, Hall of Gods is an online progressive jackpot slot title that is backed by leading software developers NetEnt. Nevertheless, for a reason that Neil is yet to understand himself, the player placed a per spin bet of £4 on the slot. 

Ordinarily, this would be considered a large per spin bet size for a newbie player – especially considering that just £30 was deposited. In fact, had Neil from Aberdeen not won on his first spin, he would have only had 6 more spins remaining at the current stake size.

All-in-all, Neil’s £6.3 million Hall of Gods win once again illustrates that just about anyone can win a life-changing amount of money in the online slots arena. At the end of the day, it’s all about timing. While you could see yourself spinning the reels for hours on end and failing to land a single big win, you could just as easily play a single spin and win millions of pounds!

  1. ‘D.P’ – £7.1 million – Mega Moolah

Surprise surprise – Mega Moolah makes our list again! Only this time, the lucky punter – known only as ‘D.P’, won the jackpot on his mobile phone. As such, the progressive payout of £7.1 million is the largest UK casino slot win of all time to be landed on a smartphone. 

The win, which came in August 2016, was won at relatively unknown gambling platform Zodiac Casino. Nevertheless, as this still stands as the biggest mobile jackpot ever, the win put Zodiac Casino onto the progressive jackpot spectrum!

Mega Moolah Jackpot Win UKHow are UK casinos able to pay such huge wins?

One of the most common questions that we get asked here at SlotBettors is with regards to a casino’s ability to pay such significant wins. Although it is true that the online slots space in the UK is absolutely booming, a multi-million-pound payout could cause severe cash flow difficulties if a single platform was required to cover the win. 

With that being said, it is technically not the specific casino that covers the win. On the contrary – as a progressive jackpot, the respective slot title will be hosted at a substantial number of online platforms and thus – player stakes are pooled together. Let’s look at a quick example so we understand how the pot increases in size.

  1. Mega Moolah is hosted at 200 individual casinos
  2. Over the course of the day, each casino takes £1,000 in player bets on Mega Moolah
  3. Although £1,000 isn’t a lot, when you multiply this by 200 casinos, this amounts to a progressive jackpot of £200,000
  4. The progressive jackpot will continue to increase in size until it is won
  5. Going with the same example as above, it would only take 5 days for the jackpot to surpass £1 million

As you will see from the above example, the progressive jackpot phenomenon allows casinos of all sizes to offer value to their players. This means that newly launched casinos with very few players can still market their multi-million-pound jackpot prizes – as long as they have access to a progressive jackpot network.

Who controls the UK casino jackpot slot prize pool? 

Continuing on from the above section, you might be wondering how each casino collects and distributes the progressive jackpot pool? In a nutshell, this role is reserved for the software developer that is behind the UK casino slot title in question. 

For example, let’s say that across 100 different casinos, the Hall of Gods slot collects £300,000 in a 24-hour period. At the end of each day, each casino would be required to tally up what they have collected, and subsequently, forward the funds onto the software developer – which in this case would be NetEnt. This allows NetEnt to keep a full birds-eye view of how much has been collected, and ultimately, what the progressive jackpot currently stands at.

At the same time, every time a spin is generated on the slot title, the developer would know how much has been inserted into the game. NetEnt would then feed this data back to the casinos that host the game via the progressive network.

So now that you know how the progressive jackpot network operates, in the next section of our guide we are going to discuss some of the best machines that typically pay the biggest UK casino slot wins.

Which machines pay the biggest UK casino slot wins?

Within the spectrum of the UK progressive slot space, there is a small number of titles that dominate the space. Because the progressive titles in question typically attract the largest pool of players, this allows the slot to increase its progressive jackpot at record speeds. In fact, it can take less than a week for a jackpot slot to surpass the £1 million mark. 

Nevertheless, here are some of the key machines that you should focus on.

  1. Mega Moolah

It may come as no surprise to learn that the number one slot goes to Mega Moolah. In fact, the slot title is known to have paid some of the biggest UK casino slot wins of all time. Although the slot game has a rather low RTP (return to player) of just 88.12%, it is important to remember that the game rarely pays a jackpot of less than 7-figures. With that being said, you should expect long periods of play where you might not catch a decent win. 

However, it is also important to note that Mega Moolah can be played from just 1p per line. As there are 25 unadjustable paylines in operation, this allows you to stake just 25p per spin. When you consider the fact that this was the stake size that allowed Jonathan Heywood to land his £13 million jackpot, this offers excellent value – even taking into consideration the low RTP rate. 

In order to stand a chance of winning the progressive jackpot, you will need to land 3 or more bonus wheel symbols. In doing so, you will trigger the Mega Moolah progressive jackpot game. This operates like a Wheel of Fortune style game. If you are able to land the arrow that takes you closer to the centre three times, you’ll win the progressive pot!

  1. Hall of Gods

Backed by leading software providers NetEnt, the Hall of Gods progressive jackpot slot makes it into a close second on our list of the best UK casino slots to play. First and foremost, much like in the case of Mega Moolah, the game allows you to stake just 1p per line. With 20 paylines in operation, this amounts to a minimum per spin bet of 20p. 

Once again, this offers tremendous value when you consider the sheer size of the jackpots that the slot frequently pays. In fact, as per our list of the biggest winners that we discussed earlier, Hall of Gods has paid a jackpot of more than £6.3 million!

In terms of the fundamentals, Hall of Gods comes with an RTP of 95.5%. This is significantly more attractive than the 88.12% that Mega Moolah offers. In real terms, this means that you stand a much better chance of walking away a winner in the long-run. Even if you weren’t to land the progressive win, an RTP as high as this makes the base game attractive, too.

Nevertheless, in order to stand a chance of landing the progressive jackpot, you will initially need to land three Thor Hammers anywhere in view. Known as the ‘Pick Win’ feature, you will need to use your virtual hammer to uncover three prizes. If you are able to match the progressive jackpot symbols, then that’s exactly what you will win.

  1. Mega Fortune

In a very close third, Mega Fortune also makes our list of the best progressive jackpots to play in the UK slot arena. In a nutshell, the game offers a traditional layout of 5 reels, alongside 25 paylines – which cannot be adjusted. 

With a minimum bet size of just 1p per line, that also amounts to a minimum spin size of 25p. For those of you that are looking to chase a big win within the base game too, you can actually play at a whopping £50 per spin. 

Mega Fortune Big Jackpot Win UKHowever, if you’re simply looking to land that multi-million-pound win, then you are actually best off playing at the minimum stakes. The reason for this is that the NetEnt-backed game has a fixed RTP of 96.4%, meaning that irrespective of how much you stake, you still stand the same chance of winning the progressive jackpot.

In order to achieve this, you will need to land at least 3 Wheel bonus symbols on consecutive reels. For example, while landing a bonus on reels 1, 2 and 3 will do the job – landing the symbols on reels 1, 2, and 4 would not suffice. 

Nevertheless, once you trigger the main jackpot feature, you will need to play the Wheel of Fortune game. In this sense, the main feature round is very similar to Mega Moolah, insofar that you need to try and move within the inner part of the wheel. Once you do, you’ll land the progressive jackpot!

Tips on finding the best UK casino slots that pay big

Although we have already discussed the best three progressive slot machines currently operating in the UK slots arena, there may come a time where you want to play a different game. If you do, you need to ensure that the slot machine in question offers good long-term value

Here are some handy tips that will set you on the right track

  1. Look at the RTP

The RTP is potentially your best friend when looking for good value progressive jackpot games. The overarching reason for this is that the RTP will dictate what your long-term chances of walking away a winner are. 

Most importantly, you need to remember that the chances of landing the progressive jackpot is super slim, so you’ll want to endure that you can grab smaller wins along the way. At the very least, this will act as a safeguard against your bankroll balance. 

With that being said, the UK casino slot space carries an average RTP of between 94% and 96%. As such, if you are able to find a progressive jackpot game that sits towards the upper end of that average, you’re potentially on to a winner. 

  1. Look at the minimum stakes

Equally as important as the RTP, you also need to make some considerations regarding the minimum stake size. Take caution here, as some progressive slots operating in the UK space are known to require an enhanced stake size in order to qualify for the jackpot. 

In our view, we would avoid these machines, as you will end up burning through your bankroll in record speed. Instead – and much like in the case of Mega Moolah, Hall of Gods, and Mega Fortune, you should pick a machine that gives you access to the main jackpot by playing at minimum stakes. In most cases, this shouldn’t surpass 25p per spin, which is great. 

  1. Check the average jackpot against the current pot

This final point is a shrewd move that will potentially give you an advantage over your fellow players. In a nutshell, each slot machine will have an average jackpot size that it typically pays out. The older the game is, the more data that you will have access to. There are now heaps of third-party websites that regularly publish progressive jackpot slots data, so you shouldn’t have any issues acquiring the information.

Nevertheless what you are looking to achieve is to find a progressive jackpot that currently has a pot that is much higher than its average payout. For example, let’s say that you are playing Hall of Gods, with the machine paying an average progressive jackpot prize of £1.5 million. If the slot machine currently has a progressive pool of £3 million, this means that the machine is due to pay out very, very soon. Once you find a slot machine that meets these conditions, you should target it.

At the other end of the spectrum, if you come across a progressive jackpot game that has a current pot size that is below its average, then you should avoid it like the plague! The reason for this is that the machine will likely need a considerable amount of time before it is ready to payout. As such, sit back and bide your time. While other players continue to feed the machine, you can then start playing the game once the prize pot exceeds its average payout.
