Progressive jackpot slots are slots where each player spin contributes a tiny amount to a progressive jackpot that builds and builds until some lucky soul finally wins it. A handful of these slots regularly pay out jackpots in excess of £1 million! If you truly wish to win a life changing amount 0f money playing online slots, then slots such as Mega Moolah and Major Millions are the way to go.

This page will tell you all you need to know about slots with progressive jackpots – how they work, how they manage to pay out such tremendous sums of money, which high-paying slots to play and where you can play them.

How Progressive Jackpot Slots Work

With such slots, a small percentage of the money paid by all players playing the slot across multiple casinos is held back to contribute to the progressive jackpot. This jackpot is hard to hit, meaning that it grows and it grows until finally, a lucky player triggers it. The jackpot, which by then should have grown to a significant amount, is then paid to them.

Say you pay £1 for a spin of ‘Mega Moolah’, the most famous and highest-paying slot with a jackpot that rolls over and over, but it’s a non-winning spin. Just under 9 percent of your fee (£0.088) gets added to the progressive jackpot, while around 81 percent is paid to the casino at which you are playing (who then go and pay Microgaming for the privilege of hosting the Mega Moolah slot at their site). That jackpot snowballs until it is won.

These life-changing slots have been around for a lot longer than you probably think. The first progressive jackpot slot was called Megabucks, and was created by IGT. Every time someone played the slot and didn’t win, a small proportion of their stake was added to the running jackpot. When someone hit a very rare combination of symbols, the jackpot would pay out. The first progressive jackpot, won in February 1987, was just under $5 million!

video slots

IGT realised that they could connect a number of identical slots together by radio signal – even across multiple casinos. This allowed the progressive jackpot to build more quickly and to be even greater in value.

The US Government made moves to regulate slots with progressive jackpots. They created a law stating that such slots could not be closed down or retired until the current progressive jackpot pertaining to them was won. This led to the Lion’s Share slot at MGM Grand being in service for two decades – well past its sell-by date! The slots’ jackpot (at $2.4 million) was eventually won in 2014, and the Lion’s Share slot was promptly unplugged!

Progressive Jackpot Slots at Online Casinos

At online casinos, slots with progressive jackpots work in much the same way, except that the connections are made over the internet rather than via radio signals. This means that anyone playing a specific progressive jackpot slot in any online casino contributes to the jackpot, which can also be won by anyone playing the slot at any online casino.

The winning of the jackpot depends on the progressive jackpot slot itself. With some, the jackpot is triggered by a very rare combination of symbols. In others, it could be because of a hard-to-achieve outcome in a bonus game. In yet others, it could be just a random award.

Many slots have multiple progressive jackpots too. The rule is the lower the payout, the more frequent the payout. Some slots have jackpots that pay out once per hour, once per day and once per week. The biggest jackpots though have no payout schedule and can be won at any time.

The Best Progressive Jackpot Slots

Now let’s take a look at what we feel to be the best slots with these life-changing jackpots that you can play at online casinos in the UK.

#1 – Mega Moolah (Microgaming)

mega_moolah_thumb

There’s no real contest when it comes to the best progressive slot. Mega Moolah is number one, always has been and always will be. It has made more millionaires than any other slot, and has paid out more in money than any other online slot in history. Despite its simplistic gameplay, thousands of people daily add money to the running Mega Moolah jackpot.

Progressive Jackpots

There are four jackpots available. These ads the Mini (seeds at £10), Minor (seeds at £100), Major (seeds at £10,000) and the Mega (seeds at £1,000,000). The average jackpot payout is around £6 million.

How to Win the Jackpot

The full jackpot is only available when playing at max coin value (if you win the jackpot at less than max coin value you win a proportion of the jackpot in line with your proportion of your stake to the max coin value).

The Mega Moolah Jackpot Wheel appears randomly. It is divided evenly into twenty sections. You receive one spin, and if the pointer lands in the single ‘Mega’ section you will win the Mega Millions jackpot!

Current Record Jackpot

The current record jackpot for Mega Moolah stands at £20,057,734.

#2 – WowPot Mega (Microgaming)

book of atem

Mega Moolah holds the record for the highest-ever payout by a progressive slot, but for how long? Well, not much longer if the WowPot Mega (also from Microgaming) has anything to say about it. As the time of writing, the WowPot Mega Progressive Jackpot stood at an impressive £40 million! Easily, a new record will one day be set.

WowPot Mega is not a slot, but a collection of them all of which contribute to the WowPot Mega jackpot. These slots include Wheel of Wishes, Book of Atem, Sisters of Oz, Sherlock & Moriarty and Queen of Alexandria.

Progressive Jackpots

Like Mega Moolah the WowPot progressive jackpot has four tiers: Mini (seeds at £10), Minor (seeds at £100), Major (seeds at £50,000) and the WowPot (seeds at £2 million). The average WowPot jackpot win stands at £8.6 million.

How to Win the Jackpot

Each individual slot has a unique way of awarding the chance to win a jackpot. For example with the Wheel of Wishes slot you need to land a giant blazing wheel symbol during a power spin. The jackpot round is also different on each slot.

Current Record Payout

The record win from a WowPot Mega slot is £15,183,085.

#3 – Jackpot Giant (Playtech)

jackpot giant

Microgaming does provide most of the biggest-paying slots in the casino industry, but it’s not quite a complete monopoly. The third highest-paying slot in casino history belongs to Playtech and is called Jackpot Giant. It’s another easy-to-play game (as this type of slot usually is), with decent payouts along with that record-breaking jackpot.

Progressive Jackpots

Unlike the two Microgaming slots we have mentioned so far, there is only one giant jackpot with Jackpot Giant, which seeds at £1 million.

How to Win the Jackpot

You must be playing at the max bet level (£4) to win the jackpot. To win it, you need to land five wild symbols on line one, which is the central line right across the middle of the reels.

Current Record Payout

The current record payout for Jackpot Giant stands at €10,710,483, making it the third highest-paying online progressive jackpot slot of all time.

#4 – Joker Millions (Yggdrasil)

joker millions

Hitting number four on our list of the top five list of the best progressive jackpots we hit Joker Millions from Yggdrasil Gaming. ‘Joker’ is a long-running theme for Yggdrasil, as they began with the popular non-progressive slot Jokerizer, then added most slots to the series, such as Lightning Joker, as they went along. Joker Millions is the company’s flagship progressive jackpot slot; others include Holmes, Empire Fortune and Ozwin’s Jackpots.

Progressive Jackpots

There is only one progressive jackpot with Joker Millions, which seeds back to £100,000 whenever it is won. The average win is just under €3 million.

How to Win the Jackpot

There is a special round with Joker Millions that can trigger the jackpot. During this round the reels repeatedly spin and joker symbols land. If any joker symbols land on any round then a re-spin is awarded. If the whole screen fills with joker symbols, then the current progressive jackpot is awarded.

Current Record Payout

The top Joker Millions jackpot of all time stands at €7,831,370.

#5 – Dream Drop Mega (Relax Gaming)

snake arena

Like Microgaming’s WowPot, Relax Gaming have their own multi-slot progressive jackpot. This is known as the ‘Dream Drop Mega’, and was first available on Relax’s Temple Tumble 2. Plenty more Relax slots have been added to the list since, including Snake Arena, Volatile Vikings and Wild Chappo. This (we think) is the only combined progressive jackpot slot to mix video slots with Cluster Pays slots.

Progressive Jackpots

There are five different jackpots available for this series. They are Mega (seeds at €500,000), Major (seeds at €25,000), Maxi (seeds at €100), Midi (seeds at €5) and Rapid (seeds at €1). The Mega Jackpot must be won when it reaches €1 million first time around, but then €500,000 is added and it can be won at any value until it reaches €10 million at which point it must be won. The €1 million/€10 million jackpots flip flop with every jackpot win.

How to Win the Jackpot

To enter the jackpot game, you need to land a Dream Drop symbol on each reel available. Further spins will add further symbols until no more symbols are added in a spin. The jackpot is awarded depending on the least number of symbols on a reel, and if that’s five, then you win the Dream Drop Mega Jackpot.

Current Record Payout

A new (since 2022) progressive jackpot slot, the top Mega Dream Drop recorded so far is €1,992,581.

Some Other Progressive Jackpot Slots

Here we outline the bare facts about ten other roll-over jackpot slots. Choose these slots (or the five above) to have the chance of becoming a millionaire with a single spin of the reels!

Types of Progressive Jackpot Slots

In truth there are not many different types of slots with progressive jackpots. They all tend to be very simple slots, with a specific way of winning the big jackpot, or at least one of them.

There are a few types though, and here we take a brief look at the differences.

Single Jackpots

This type of progressive jackpot slot is rare. All monies added to the slot’s jackpot are for that slot, and that slot alone. As you might imagine, the jackpot for such slots never climbs that highly.

Single Site Jackpots

Usually, a progressive jackpot is shared among a slot across multiple online casinos. For example, anyone can win the Mega Moolah jackpot as long as they are feeding their virtual coins into the slot – it doesn’t matter where they are actually playing the game.

On the rare occasion there could be a progressive jackpot slot that is for one site only. Again, and as you might imagine, the jackpots for such slots never rise to the levels of similar slots that can be found across multiple casinos.

Multiple Slots Jackpots

We have already covered this with some of the ‘best’ progressive jackpots slots mentioned above. The jackpot is shared among a small number of slots, and can rise to incredible levels. Microgaming’s ‘WowPot’ is a good example of this.

‘Any Slot’ Jackpots

A very small number of providers have a progressive jackpot slot that can be won by playing any slot that they create at any online casino that has their games. A fine example of this is PragmaticPlay’s ‘Drops & Wins’ jackpot. This jackpot is randomly awarded to anyone playing any of their slots at any participating online casino.

Multi-Jackpot Jackpots

Mega Moolah is an example of a multi-jackpot progressive jackpot slot. There are four different jackpots and the rule is the smaller the jackpot, the easier it is to win. The biggest jackpot is the one worth winning though, naturally!

Single-Jackpot Jackpots

Single jackpots are actually less common than multi jackpots, but they are still worth winning! You really don’t need an explanation from us of how they work, surely?

How to Win Progressive Jackpots Slots

Well, if we knew this there are two things you would be aware of (a) we wouldn’t tell you and (b) we’d be writing this from our holiday home in the Bahamas! As (b) is not true, let’s get to (a).

These types of win are awarded randomly and there is no way of guaranteeing a win – there are no tricks, no hacks, no backdoors. The number crunching associated with ALL slots goes on at secure, un-hackable servers. Winning a progressive jackpot is a matter of luck and nothing else.

One thing you should know though is that to win the full amount of the jackpot, you need to be playing at the maximum bet level, which is a rule true of most slots of this type. There can be no worse feeling than thinking you’ve won £10 million when, as you have only been at ten percent of the max bet level, you’ve only won £1 million … well, that’s still pretty good but you can see what we are getting at.

The Probability of Winning a Progressive Jackpot Slot

Just how likely is it that you will win a progressive jackpot? This is not good news … the odds are somewhere between one-in-50 million to one-in-6oo million. You are much more likely to be struck by lightning, killed by a shark and dying on your birthday than winning a progressive jackpot … all on the same day.

So, why play them? Well of course, such slots pay out more than the jackpot. As you are playing them, they work in exactly the same way as ‘normal’ slots with plenty of ‘mundane’ jackpots. This means you can play them with the hope of winning the big one but still with a very good chance of coming out on top.

Compare this to buying a lottery ticket … you’re actually unlikely to win anything (or just your money back) and aside from the thrill of buying a ticket and watching the numbers, buying a lottery ticket is simply not as entertaining!

Where to Play Progressive Jackpot Slots

Most online casinos will have progressive jackpots slots. Look for casinos that have Microgaming slots, as Microgaming are the kings of these life-changing jackpot slots.

The majority of online casinos that we recommend have these type of slots. Learn about our recommended online casino sites.

Example of Big Wins and Jackpots

Many people have beaten the odds and won on slots with rolling-over jackpots, and here are some of their stories.

jon heywood mega moolah win For many years Jon Heywood from Crewe in the UK was the talk of jackpot slots winners. The soldier became a multi-millionaire overnight in 2015, winning £13.2 million on Mega Moolah at the Betway online casino. The kind-hearted Heywood said that his first priority with his new-found wealth was to hurry along the medical care needed by his ailing father, and that also he would treat all his relatives to a Mediterranean cruise. He also said though he would be splashing out on a luxury car – a yellow Bentley Continental GT.

The last time he was heard of Heywood had followed through with his promises and was running his dream business, buying and renovating homes and then selling them on.

napoleon jackpot The record win for a progressive jackpot slot win was held by Heywood for almost six years before it was finally beaten to set a new record which, at the time of writing, still stands to this very day.

This record was also set by Microgaming’s top progressive jackpot slot Mega Moolah. In April 2021 it was won – at the princely sum of €19,430,723.60 – by a Belgian playing at the Napoleon Sports & Casino online casino (not a UKGC casino, so unavailable to UK players).

Sadly for us, the lucky winner will remain a mystery, as the resident of Belgium chose to remain anonymous.

book of atem jackpot

You may think that Mega Moolah has the mega monopoly on mega progressive jackpot wins, but that’s only around 95 percent true (of the top twenty progressive jackpot wins of all time, Mega Moolah accounts for 18 of them). The biggest jackpot win of all time on a slot that is not Mega Moolah is still very impressive at£15,183,085.96.

This was set on The Book of Atem: WowPot, created and managed by (you guessed it) Microgaming! It was won in April 2021 at the 32Red casino, and it was won in the good old U of K.

The user chose to remain anonymous but this story has one key detail – because ‘WowPot’ is a randomly-awarded jackpot it can be awarded for any amount bet. The lucky punter managed to turn just eighty pence into a £15 million fortune!

Progressive Slot Bonuses

You may be asking yourself does a concept such as ‘progressive slot bonuses’ exist? These would be bonuses offered by online casinos in the UK that enable you to play progressive slots for free, or for bonus money.

There’s an exact answer to this – ‘no’, and it’s a big ‘no’. Unlike ‘normal’ slots, progressive slots jackpot wins are paid by the company that made the slot (Microgaming, Playtech, NetEnt etc) and not the casino itself. Because of this, online casinos are not able to offer progressive slot bonuses.

What’s more you will find that when working through wagering for a bonus, playing on these type of slot makes absolutely no contribution.

How to Play Progressive Slots on Mobile

Slots work brilliant on phone and tablets. They don’t take up much screen space, so it’s much more convenient to play slots on your mobile devices than having to sit at a desktop PC, or with your laptop sat upon your lap.

There are no limitations to playing progressive slots on mobile, and they function in exactly the same way as playing them in any other fashion. A small number of online casinos have downloadable casino apps you can install on your devices, but most of them can easily be played in your favourite mobile browser.
