One of the reasons progressive slots can be so rewarding is because they’re available at hundreds of online casinos. As such, players have a wide selection of trusted brands to choose from. We’ve narrowed your choices down with a hand-picked list of the best UK casino sites for jackpot slots.

Top 5 Progressive Jackpot Games

There are quite a few progressive jackpots online, and many of them are worth playing for different reasons. Yet, a few standouts make the headlines on a consistent basis. The best progressive slots offer a combination of factors to players:

  • High Jackpots
  • Satisfying Gameplay
  • Decent RTP
  • Solid Graphics & Animations
  • Relatively Frequent Jackpot Payouts

Let’s single out the top 5 progressive jackpot slots. All of these games are common at leading UK online casinos.

Mega Moolah – Microgaming’s Jackpot King

mega moolah slot jackpot

Released: 2006
RTP: 94%

Mega Moolah is arguably the number one progressive jackpot on the online market. If your first impressions of this slot aren’t that great, we’re right there with you. The game’s graphics are slightly outdated, and its mechanics are nothing out of the ordinary.

Not many people play this slot for the eye-candy, but rather its immense payout potential. On average, Mega Moolah’s jackpot varies between £4m-£6m.  

Featuring 5 reels, 25 paylines, and a minimum bet of £0.25 per spin, Mega Moolah is a downright standard video slot. As usual, you have a handful of symbols with various payout multipliers, as well as a Wild symbol. The Scatter activates the bonus game, rewarding you with a number of free spins.

Those who haven’t played Mega Moolah have certainly heard of its multi-million jackpot prize. However, Mega Moolah actually has 4 jackpots: Mini, Minor, Major and Mega.

The lesser jackpots drop much more frequently, and prizes range from a few hundred quid up to a few thousand. The jackpots can be won through the Jackpot Bonus, a randomly triggered Wheel of Fortune-esque bonus game.

It is unreasonable to play Mega Moolah with the mindset of winning the Mega Jackpot. This requires an extraordinary amount of luck, but the game itself can compensate for your time in different ways. Whether through the lesser jackpots, or its regular free spins round and Wild symbol.

Mega Fortune – NetEnt’s High Class Jackpot

Released: 2006
RTP: 96%

Mega Fortune is Net Entertainment’s flagship progressive jackpot. At the same time, it shares the title of best jackpot slot with Mega Moolah. We can’t know the exact amount of this game’s total jackpot payouts over the years, but it certainly ranges in the tens of millions.

Aesthetically, Mega Fortune boasts a modern layout with solid graphics and a luxurious theme.

Gameplay-wise, we found the base game marginally more forgiving than Mega Moolah. You have your standard set of symbols, plus a Wild. On top of that, 3 champagne symbols will activate the bonus game, generating a decent amount of free spins.

On average, your chances of maintaining a steady bankroll are decent. Still, Mega Fortune’s payout frequency is nowhere near the likes of Blood Suckers or even Starburst.

Mega Fortune has 3 jackpots: Rapid, Major and Mega. The minimum jackpot amounts to be won are £50 (Rapid) and £5000 (Major). Open the slot at any random moment, and the Mega jackpot will probably number in the millions. To get a shot at winning one of the jackpots, you’ll need to activate the Jackpot Wheel by way of 3 or more bonus symbols.

Arabian Nights – NetEnt

Released: 2013
RTP: 95.62%

Following the success of Mega Fortune, NetEnt decided to expand its jackpot portfolio. Thus, Arabian Nights was introduced to the market.

Once again, we have a pretty barebones slot structure with 5 reels, 10 paylines, and a single bonus round. Arabian Nights’ bonus round can net you 15 free spins with a 3X multiplier. It is activated through 3 or more Scatter symbols.

The good news is that this slot can be played with a minimum bet of 10p per spin. However, this progressive is not for everyone. To have a chance of winning the jackpot, you will have to place wagers with the maximum bet of £5 per spin. If you’re not a high-roller, then this bet requirement is not sustainable.

Arabian Nights’ jackpot can be won by way of 5 Arabian Prince symbols appearing on your reels. If you trigger 5 of these symbols without a max bet stake, you will be rewarded with 10,000 coins instead of the jackpot. This is still pretty decent, but its nowhere near the multi-million potential this slot is capable of.

Arabian Nights is the only NetEnt slot that can be both local and progressive. This depends on the online casino you’re playing at, and the type of agreement they have with NetEnt.

Age of the Gods – Playtech UK

Released: 2016
RTP: 95.02%

Following the breakdown of Playtech’s partnership with Marvel, the Age of the Gods progressive slot was introduced. It is the successor of the provider’s Avengers, as part of their Marvel progressive network. As such, Age of the Gods has numerous variants as well: Fate Sisters, King of Olympus and Goddess of Wisdom, to name a few.

Our focus here will be on the original Age of the Gods, but the game’s jackpot is shared between all titles. What’s more, the jackpot increases in size from bets placed across dozens of UK casinos. This is why it often ranges in the seven-digit department.

Playtech’s Age of the Gods is one of the most feature-rich progressive jackpots on the market. The game has 4 Free Spins features: Athena, Zeus, Poseidon and Hercules. Moreover, you can look forward to expanding wilds, multipliers and the Pantheon of Power random trigger.

Most importantly, Age of the Gods has 4 progressive jackpots. And the highest jackpot can make you a millionaire.

Playtech’s Age of the Gods is perhaps the best progressive slot that is also suitable for regular gameplay. The fact that it can be played with bonus cash is just the cherry on top.

Cleopatra Mega Jackpots – IGT

Released: 2015
RTP: 93%

IGT’s Cleopatra has been one of the most popular slot games for quite a while now. Now, it is also available in a jackpot variant, but the base game is essentially the same. Naturally, the RTP is lower than the original to make up for the jackpot.

What’s interesting about Mega Jackpots Cleopatra is that the chances of winnings increase as the jackpot itself rises in value. Though, this means you’d best avoid it until it’s reached a certain point. Our advice is to wait for the £1 million mark, as only then does the slot RTP reach 93%.

To win the jackpot, 5 Wild symbols will need to line up on the centre-most reel.

Those unfamiliar with the original Cleopatra can rest assured that the game offers more than a jackpot. Besides the Wild, a free spins round with an X3 multiplier can make for some decent winnings.

IGT’s Mega Jackpot series contains titles such as Wheel of Fortune, Siberian Storm, Star Lanterns, and a few others. They are all inter-connected in a progressive network available across many UK casinos. 

Highest Jackpot Winners on Record

The highest jackpot wins to date all come from the famous Mega Moolah and Mega Fortune, which goes to show why these progressive slots are so popular.

Have a look at top 5 online jackpot slot winners’ chart below.

Just the top five winners combined surpass the £70,000,000+ mark, which truly highlights the potential of progressive slots. These jackpot winners come from all across the globe. For obvious reasons, some of them decided to stay anonymous, whereas others made their winnings public. Without a doubt, it was a life-changing experience for every lucky player.

How Do Progressive Jackpot Slots Work?

Progressive jackpots are essentially similar to video slots, but with one key difference. They feature a large jackpot prize that progressively increases from a small portion of each player-made bet.

Of course, this bet portion that goes into the jackpot isn’t literally taken from your wagers. Instead, to compensate for this mechanic, software companies create progressive slots with lower RTP and higher volatility. As such, these games aren’t best suited to casual players. 

Each progressive slot starts with a baseline jackpot value, which is then increased as bets start pouring in. Once someone wins the jackpot, the value resets and the process repeats from scratch. Typically, an online progressive will dish out its major jackpot once every month or two.

Let’s look into the various types of progressive slots you can expect to find in UK online casinos.

Types of Jackpot Slots

Online casinos are known for their game variety, which is mirrored even in the somewhat limited category of jackpot slots. While on the surface they all seem the same, progressive slots are split into several categories. Let’s go through each one and see what sets them apart.

Local Jackpots

Local jackpots are games whose jackpot is pooled in from player bets in a single casino, or a series of casinos owned by the same operator.

Of course, local jackpots are still considered progressives, but for obvious reasons their jackpot will be significantly smaller. In contrast, your chances of winning a local jackpot are much higher. This is because you are competing with way less players. In this case, playing at a new or less popular casino may be beneficial. In fact, it will probably provide you with the best odds of winning one of those coveted six or seven-digit jackpots.

Yggdrasil Gaming’s Ozwin’s Jackpots and Jackpot Raiders are good examples of local progressive slots.

Network Jackpots

These jackpots are the most popular, and they garner the most attention. The reason is simple. Network jackpots are increased by player bets from hundreds of casinos.

This is literally the case with one of the best jackpot slots on the market – Mega Moolah, which is why its dished out several nine-digit payouts to date. Playtech’s Age of the Gods and IGT’s Mega Jackpots series are a few other examples of mega-popular network jackpots.

A network progressive jackpot win can change your life with a single spin. Yet, the odds of winning one are right up there with winning the lottery.

Multiple Jackpot Slot Games

Multiple jackpot progressive are slot games that typically have 3 or 4 jackpots all running at the same time. Usually, jackpots are separated by small, medium and large.

Such is the case with many popular network progressive slots. The smaller jackpots drop often, which incentivizes many players to try their luck. These smaller jackpots can serve as a consolation prize to those who risk a lot in pursuit of the major win.

The industry’s most popular progressive slots, Mega Moolah and Mega Fortune are both multiple jackpot slot games.  

Must-Drop Jackpots (Daily Jackpots)

If winning a jackpot is your ultimate goal in online gaming, then Must Drop jackpots are your best shot.

These games are pretty self-explanatory; their jackpot must drop by the end of the day. There has to be a winner no matter what, which is these slots are also known as Daily Jackpots.

Must Drop jackpots can be progressive or fixed, but they are still smaller in comparison to the most popular online progressives.

If you’re willing to try your luck in some Must Drop slots, have a look at Red Tiger Gaming UK casinos. Our personal recommendation is 888 Casino.

How Do You Win a Progressive Jackpot?

There are several common ways of winning a progressive jackpot: random triggers, bonus rounds or a combination of symbols.

No matter how you trigger the jackpot, this is still not a guarantee of winning the main prize. Typically, the jackpot trigger will simply take you to the bonus game or jackpot wheel. It is only then that you have a chance of winning the jackpot.

It is common knowledge for many progressive slots that higher bets give you more chances of triggering the jackpot game.

Yet, it’s important to remember one major distinction: higher bets do not give you better odds of winning the jackpot itself. Instead, you have a higher chance of simply activating the jackpot round. To illustrate, one of the biggest online jackpot win to date came from a minimum bet (£0.25) spin.

Some games have a minimum wager amount requirement. Meaning, a £0.25 spin may be invalid for jackpot wins. Before playing a progressive slot, make sure to check up on the game rules and jackpot requirements. You don’t want to feed the jackpot without even a slight chance of winning.  

Can Players Win a Jackpot Playing with Bonus Money?

In a time where online casinos and bonuses are inseparable from each other, it’s important to know whether you can win a jackpot with bonus funds. Unfortunately, the answer is no for the most part.

In rare cases, you will have the chance of winning the coveted jackpot with an active bonus. Playtech’s Age of the Gods series of slots is one such example. What’s more, these progressive jackpots are prominently available at some of the best UK casinos around.

At many casinos, you will be allowed to play a progressive slot with bonus cash, but you won’t be able to win the jackpot. Whereas, some casinos completely restrict jackpot games from wagering. Before claiming a bonus offer, make sure to read the terms and conditions to avoid any misunderstandings.

Perhaps the better question would be: should you play a jackpot bonus money? If your purpose is to wager your bonus as efficiently as possible, we wouldn’t recommend it. This is because most progressive slots have high variance and low RTP, and they can drain your bonus money in the blink of an eye.

Jackpot Slot Strategy Tips

It’s only natural to be wondering how do you win an online jackpot. After all, we’d all like to be millionaires. The reality is that you have to get really lucky, but we can still offer some sound advice that will slightly boost your chances of winning.

We already know that different slots have different rules, and some have a higher minimum bet requirement for a jackpot win. However, we have one universal tip for you: always bet on the maximum paylines. Keep in mind, this does not mean betting the maximum amount.

For instance, a typical video slot has 25 paylines, and you can bet on each payline with £0.01. This results in a maximum payline bet of £0.25. Wagering on fewer paylines than the maximum significantly lowers your chances of triggering any winning combination, let alone the jackpot.

Winning a jackpot also depends on the game type you are playing. Fixed and local jackpots are inherently easier to win. Then, you have the Must Drop jackpots.

If you are playing a network progressive slot, remember that not all of them are the same. Some have very barren base games, whereas others are more rewarding even without the jackpot. Check up on the RTP, volatility and other game details before playing. Many of them can also be tested in demo mode so that you can get a feel for the mechanics.

Is It Worth Playing Progressive Slots?

The headlines can make everyone’s head spin. Surely, just the thought of winnings a multi-million jackpot can spark a wave of crazy ideas in our minds. Yet, after landing back in reality, we must beg the question: Are progressive slots worth it?

It depends. We all dread this answer, but in this case, it’s the only answer. As we said before, nobody can realistically expect to win a jackpot. No one can realistically expect to “turn a profit” in any online casino game, for that matter. It all comes down to luck. In the case of progressive jackpots, it comes down to ludicrous amounts of luck.

The most important things to remember is to play within your limits, take frequent breaks and don’t chase losses. As long as you play with what you can afford, then a few spins on a progressive slot surely won’t hurt.  

On average, you’ll get a higher return by playing video slots, but let’s see why. As you read below, we’ll have a look at the differences between regular video and jackpot slots.  

Jackpot Slots VS. Regular Video Slots

Looking on the surface, there isn’t much difference between regular and jackpot slots. Yet, any experienced player can tell the differences from miles away.

The most obvious one is the variety. Approximately, there are a couple of dozens of progressives out there. Video slots, on the other hand, range in the thousands. They come with loads of themes (mythology, pop culture, music, fantasy, sci-fi), all sorts of bonus features and innovative mechanics. What’s more, new video slots are released on a regular basis, especially by companies such as NetEnt, Microgaming and Yggdrasil.

Then, we have the graphics. Progressive slots don’t have the luxury of exploiting technological progress. For instance, everybody knows Mega Moolah for what it is. If Microgaming were to remake it, there’s no telling whether it’ll be as popular among players. Video slots keep raising the bar in terms of aesthetics, meaning you can always expect the most visually pleasing games on the market.

Perhaps the most important difference is the payout rate. We mentioned before that progressive slots have an inherently lower RTP and higher volatility. This makes them unsuitable for many players, who may often face long payout droughts during gameplay. In contrast, many video slots boast frequent payouts and high RTP. This makes them ideal for lower budgets and bonus wagering. Take Yggdrasil’s Vikings Go Berzerk as an example, but hundreds of similar games exist.

The reality is, when you’re trying to win a big progressive jackpot, you’re competing with thousands of players. There can be only one winner. You could play for months on end and still come up empty-handed. Ultimately, it depends on your budget, but if you’re looking for the best bang for your buck; video slots clearly take the cake.  

In Summary…

The key points you should take from this article: if playing progressive jackpots, always bet on maximum paylines. Look up game rules, RTP and volatility to see if a game suits your taste. The best jackpot slot games are those you like the most. Local and fixed jackpots are easier to win. If you’re looking for cost-efficiency: regular video slots are a much better choice. Last but not least: never bet more than you can afford. Good luck, and have fun!
