The first progressive jackpot slot was Microgaming’s Mega Moolah. This game took the industry by storm and many exciting progressive jackpots have followed since. Progressive jackpots slots are different to normal slots in that each time a player wagers they are contributing to the jackpot. It keeps growing until it is hit by a very lucky player.
When it comes to progressive jackpot slots, there are also different kinds you will find. These are Network, Fixed and Local.
What makes progressive jackpots so appealing in the UK is that there is the chance to win a huge amount of money. They can offer the chance of a life-changing win. Progressive jackpots often rise to several £ million. But the biggest sum won on a progressive slot was $38.4m (£30.4m) on Wheel of Wishes in December 2023. Some Christmas present, right?
Every progressive jackpot slot you find will work in a similar way. Every time a player makes a wager, a percentage of this is taken to contribute towards the progressive jackpot. This jackpot keeps growing with each person who plays the game. Eventually, at an unpredicted, random time, one lucky person will win this progressive jackpot.
Once the jackpot is won, the pot is reset, and the process starts again with the players contributing to the pot as they play the game.
Everybody plays a progressive jackpot slot with the hopes of hitting the jackpot. There is no way of telling when a jackpot will hit. It is just the luck of the draw. You can spend hours playing a game and as soon as you stop the next spin could hit the jackpot. This is how progressive jackpots keep you in anticipation.
There have been some massive progressive jackpot wins over time. Here are the top 5 biggest progressive slots jackpot wins of all time.
| Game | Jackpot Amount | When |

Progressive jackpot slots are popular all over the world, given their potential to pay out a huge prize for a relatively small play amount. There are plenty of global jackpot success stories, but what about the biggest progressive jackpot winners in the UK?
The biggest ever progressive jackpot win in the UK was back in September 2018, where a player won £18.9m on the Mega Moolah slot. However, details of the winner, and where he was playing at the time, are somewhat sketchy.
We’ve managed to track down some confirmed jackpot wins recorded by some of our recommended UK casino sites:
Betfred - A record win of £11.4 million was paid out by Betfred in June 2025. The customer, who preferred to remain anonymous, had only signed up at Betfred the day before, and was playing on Mega Moolah for £1.50 on a spin when he landed the jackpot.
BetVictor - October 2023. A man from Aberdeenshire, who also chose to remain anonymous, won an impressive £5,400,000 from a £0.20 spin on Hall of Gods. At the time, it was BetVictor's biggest-ever payout, and it happened just six months after another jackpot win of £4.5 million on the Mega Fortune slot.
Casumo - Neil from Aberdeen, who was “killing time” on his laptop, decided to sign up at Casumo in November 2017 because the site “looked like fun”. He played a £4 spin on Hall Of Gods, where he hit the Mega Jackpot, and received a life-changing payout of over £6.3 million.
The answer to that question is rarely! But before you look elsewhere, allow us to explain why that is.
An online progressive jackpot slot typically has a low RTP (Return To Player) percentage and high volatility. The lower the RTP, the smaller the probability of spinning a winning combination, based on gameplay over a period of time.
Meanwhile, high volatility indicates that there are fewer wins, but when a winning combination of symbols does come up, the payout is typically much bigger.
All jackpot slots start with a generous ‘fixed’ jackpot amount. Every time the game is played, but the jackpot isn’t won the overall prize pot grows. When the big prize is eventually won, the jackpot resets to its original fixed figure, and the whole process begins again. As an example, the Mega Moolah games collection resets to £1 million.
However, there is no quick turnaround with these games. Some of the most popular progressive jackpot slot machines won’t pay out the jackpot prize for months on end, years sometimes. But in the meantime, the big jackpot prize can grow to some truly eye-popping figures.
There are many great progressive jackpot slots available to play at the best online casinos in the UK. Here are five of our top recommendations for you to try out. They have proven to be very popular.

Progressive jackpot slots are a type of online slot game where the jackpot prize increases every time a player places a bet. A small portion of each wager is added to the jackpot pool, which continues to grow until one lucky player hits the winning combination. These slots can offer massive payouts, often reaching into the millions, and are typically linked across multiple casinos or games to build even larger jackpots. Progressive slots usually feature a special bonus round or specific symbol combination required to win the top prize. They are popular among players seeking high-risk, high-reward gameplay with the potential for life-changing wins.
Whether progressive jackpot slots are better than standard slots depends on your playing style and goals. Progressive slots offer much larger potential payouts, often reaching millions, but the odds of winning the top prize are significantly lower. Standard slots, on the other hand, typically provide more frequent wins and consistent payouts, making them a better choice for players who prefer lower risk and longer play sessions. While progressive slots appeal to those chasing big jackpots, standard slots may offer better value in terms of return-to-player (RTP) percentages and overall gameplay experience. Choosing between the two comes down to your personal preference for risk versus reward.
Mega Moolah by Microgaming is a very popular progressive jackpot game. It's huge fun to play, with fascinating mechanics, and it has produced the biggest payouts of all time.
There is no way of telling this as they are completely random. It really depends on the game you are playing, but it can be several months, or even years before a jackpot slot releases it's big prize.
I does depend on the casino you are playing at, but typically, jackpot slots are not offered in demo mode. However, it's often possible to play them for real with spin amounts from as little as £0.10.
