As we mentioned earlier, jackpot slots vary in a number of ways. We’ll show how the above titles compare by taking a closer look at each one below.

Mega Moolah

  • RTP: 94%
  • Highest Payout in the UK: £13.2 million

If you’ve ever played jackpot slots, then chances are that you’ve heard of Mega Moolah. The Microgaming slot currently holds the record for the highest payout. We’ll take a look at that later on though.

The slot is set in the African Savannah. The audio-visuals are anything you’d expect from a slot of its age. But that’s not why to play Mega Moolah; triggering the wheel game is.

The trigger is random but if you are lucky enough, there are 4 progressive jackpots that you can win.

For more information about Mega Moolah, we recommend reading our slot review.

Mega Fortune

  • RTP: 96%
  • Highest Payout in the UK: £6.2 million

Before Mega Moolah took the record in 2018, NetEnt’s Mega Fortune was considered the highest paying jackpot. The slot is still a top contender in the UK.

As the name implies, the game is based around the theme of money. Again, this is another aging slot, but it looks are considerably better than its Microgaming rival.

So how to trigger the progressive jackpot? This time you’ll need to land 3-wheel bonus symbols. You’ll then be asked to spin another wheel where you can either win coins or move onto the next wheel.

Only the second and third wheels offer jackpot wins and the slot has 3. We provide more details about Mega Fortune jackpots in our slot review.

Jackpot Giant

  • RTP: 94.22%
  • Highest Payout in the UK: £10.7 million

In 2016, Playtech set the UK record for the largest jackpot won on mobile. And they did it with their Jackpot Giant slot. The software provider is actually best known for their mythological slot Age of the Gods.

Nevertheless, it’s their giant themed progressive slot that records the highest payouts. In order to hit the jackpot, you’ll need to land 5 wild symbols. But you’ll also have to play at the maximum bet level to be eligible.

Jackpot Slot Providers – UK Favourites

We’ve looked at the top jackpot slots so now we’ll delve deeper and take a look at the best software providers. As you probably know, there are hundreds of games studios out there and most of them offer at least a few progressive jackpots.

In many cases, the jackpot is actually shared across one network. We’ll discuss this in more detail when we look into pooled jackpots. For the time being, here’s our pick of the top providers for jackpot slots in the UK.


Microgaming is best known for their Mega Moolah slot, as mentioned earlier on. What some of you might not realise is that they offer many other jackpot slots too.

Major Millions, for instance, is another progressive which often racks up million-pound prize pools. As is King Cashalot, a similarly aged slot which focuses on the theme of fortune.

The provider’s jackpot slots probably aren’t the most innovative in terms of audio-visuals. In fact, many of Microgaming’s top titles have been around for a while. But the provider still comes out on top because of the high payouts they offer.

King Cashalot £0.45 - £2.25 €1,520,000


Over the years, the provider NetEnt has built quite a reputation for themselves, particularly when it comes to non-progressive slots. As we have seen earlier on, they’re just as well known for their jackpot slots. Mega Fortune has one of the fastest accumulating jackpot meters out there.

Arabian Nights is another favourite. Even though it is one of the older jackpot games, its functionality has meant that it is still extremely popular today. As the name implies this is set around the story of Aladdin. Although aesthetically the game's age is apparent, you can still expect some top prizes with this one.

A popular theme within video slots is Greek Mythology and if you are a fan of this then you're still covered with Hall of Gods. Its jackpot amount is definitely smaller than others but it's quality features and bonus rounds still make it a lot of fun.

With over 30 progressive jackpot options to choose from, Playtech is a favourite, particularly in the UK.

They are well known for their top performing series, 'Age of the Gods'. Although it is not the best opportunity to take home large prize pools, the series boasts 6 titles to choose from. New titles are constantly being added.

On the other side of the spectrum we find their highest paying fortune slot, 'Jackpot Giant'. One downside to this slot that we highlighted earlier on is that you need to play the maximum bet to be eligible for the jackpot.

A good alternative with a 7-figure jackpot is Beach life. It also has some great bonus features and is easier to do well on.

888 Exclusives – Worth a Mention

As well as offering slots from top providers, some online casinos take things one step further by offering proprietary games. 888 Casino is a good example of this boasting over 35 jackpot slots that are exclusive to the gaming site.

They don’t offer the same level of quality and features as some of the other top jackpot slot providers. This said, 888 jackpot slots are still popular and that’s mostly because of their exclusivity.

The biggest ever prize that a jackpot winner has taken home was on Millionaire Genie. This is a classic progressive game with a single payline. The popular slot shares its prize pool with some other slots such as Irish Riches and Rise of the Pharaohs.

In October 2015, Jonathan Heywood won £13,209,300 on Mega Moolah. And he won it on a spin at minimum bet level! That UK record still stands to this date.

Many of the other wins listed above tell similar tales of first timers who got lucky. It goes to show that you don’t always need to bet big to hit the jackpot. In fact, gambling responsibly should be the top priority.

What are Jackpot Slots?

Jackpot slots, as the name implies, are regular slots with an added ‘jackpot’. Most video slots bear a fixed payout but with these slots, the prize accumulates over time and this is why it varies.

As you can probably imagine, jackpot slots are sought out by players, particular high rollers. This is why most online casinos will often have a separate section within their games lobby just for these games.

The prize pool will depend on the actual slot. As we have seen earlier on, certain titles are known to offer higher payouts. But that usually comes at a trade-off, such as a less frequent hit rate. The size of the jackpot also depends on the type, which is something that we’ll take a look at next.

Local vs Pooled Jackpots

Each time you place a bet on a progressive slot, a portion of this is immediately added to the jackpot amount. This is how the value increases over time.

In most cases, the value is the same, regardless of the online casino. This is what we refer to as a pooled jackpot. As you can imagine, network jackpots accumulate quickly and lead to the highest payouts.

Local jackpots on the other hand are specific to each casino. The slot may be widely available, but you’ll notice that the jackpot size is different for each. As a result, the prize is usually much smaller, but you have the advantage of less players looking to win the jackpot.

One example of a local jackpot is NetEnt’s Divine Fortune.

Fixed vs Progressive Jackpots

Fixed jackpots are often confused with progressive but they’re actually two different categories. The first refers to regular videoslots with an added in-game feature. In this case, the size of the jackpot won’t change.

Progressives on the otherhand, accumulate over time according to players’ bets. For this reason, providers cannot give fixed values. This is why many online casinos provide an interactive jackpot tracker.

Some online slots actually have both a fixed and a progressive jackpot. The latter is of course much higher but it’s also much harder to win.

Progressive vs. Online Slots – Which to Play?

Why play progressive jackpot slots anyway? This is a question you’re bound to ask at some point. Obviously, the prize is much bigger but as you’ve probably realised, your chances of winning aren’t very high.

Progressive slots or video slots? We’ll take a look at some of the reasons to play each below.

Advantages of Jackpot Slots Advantages of Regular Slots
Multi-million-pound prize pools More choice
Pooled jackpots accumulate quickly Generally, less volatile
Popular with high rollers Higher average RTP
Some players like the element of risk Graphics are more innovative
Top progressives are globally renowned More commonly associated with free spins bonuses
Highly volatile and thrilling  

At the end of the day, choosing to play a jackpot slot comes down to the type of player you are. If you’re after small yet frequent wins then you’re probably better sticking to regular video slots. If you’re willing to wait though, a jackpot slot can pay off nicely and it has for some, as we saw earlier on.

How do you Win the Jackpot on Slot Machines?

Every jackpot lover’s dream is to get their hands on a winning formula. Slot games make use of RNG software and this is actually in your interest. It means that games cannot be fixed.

In fact, any reputable software provider will ensure that their jackpot slots are audited by the likes of eCogra. This helps to further promote game fairness.

What this RNG software also means is that there is no way to predict when you’ll trigger the jackpot slot. We can however provide you with a winning strategy as shown below.

Jackpot Slot Strategy

  • Set a clear budget: money management is the top priority. Always separate your personal bankroll from your gaming one and set clear targets. This way you’ll know when to stop.
  • Choose your jackpot slot with care: take a look at the RTP value for each slot beforehand. You may also want to study the history of jackpot wins to see if there’s a pattern.
  • Study your progressive slot of choice: make yourself familiar with how the slot works as well as all of the in game features
  • Check the jackpot tracker before playing: this will change according to when players hit a win
  • Check for any casino bonuses: although they are uncommon, some casinos do offer bonuses on progressive slots like Age of the Gods.
  • Check the bet limits: some slots will require that you bet a certain amount to be eligible for the jackpot.
  • Higher bets can increase your odds: many jackpot slots make this clear in their terms however we also recommend gambling responsibly.

How often do Progressive Jackpots Hit?

There is no fixed time period to when jackpot slots hit. Plus, it varies according to the different types out there. It can take days, months or even years for a jackpot prize pool to be claimed.

Local jackpots, are known to be claimed quite often, but the prize will be much less than some of the bigger ones. On the other hand, the popular Mega Fortune and Mega Moolah jackpots can take close to a year for someone to trigger the jackpot feature.

Some of Playtech’s DC Comics jackpot slots have a decent jackpot hit rate. However, we’re not fond of their low in-game hit rate. They end up being boring because it takes too long for any of the bonus features to trigger. And we can all agree that nobody likes to play for the sake of spinning reels.

If you want a better chance of winning a progressive jackpot, we recommend the likes of Divine Fortune and Mega Moolah Isis. On the other hand, if you’re in for the long haul, go for the elusive Mega Fortune and Mega Moolah.
