Written By Scott Lawson
On this page, you’ll find everything you need to know about progressive jackpots in the world of slots. Not only will we cover the titles with the biggest jackpots, but we’ll also introduce you to game types, bonuses, and the best casinos to play them.
The Largest Progressive Jackpot Slots
For those of you who want the chance to win truly life-changing amounts of money, then slots with progressive jackpots are the logical choice. Yet not all of these types of slots have especially high jackpots or are particularly entertaining to play. Here you can see an overview of the top 3 jackpot slots, which are popular, entertaining and provide the chance to win staggering sums of cash. In fact, all of these games have paid out individual jackpots in excess of a million each.
| Jackpot Slot Game | Current Jackpot | Software Developer | Where to Play |
|---|---|---|---|
| Mega Moolah – Rating: 5/5 | £ 6,414,047.86 | Microgaming | Play at Duelz |
| Mega Moolah ISIS – Rating: 5/5 | £ 3,559,109.67 | Microgaming | Play at Duelz |
| Hall of Gods – Rating: 5/5 | £ 3,493,404.25 | NetEnt | Play at Mr Green |
If you want to know just how high a progressive jackpot can reach, then look no further than Mega Moolah. This game recently set a new world record for the highest payout from an online slot. The massive €17.89 million win only just broke the previous record of €17.8 million, which was set by Mega Fortune. The sequel to this game – Mega Fortune Dreams is another huge hit with players, thanks to its consistently high jackpot, which regularly stretches into the millions.
All Millionaire-Making Jackpots and Where You Can Play Them
Here you will find all jackpot slots which have broken the million-pound payout mark. When it comes to these types of slots, there are several facts and figures that are of interest. Of course, the highest jackpot payout ever made is a big highlight of the games.
But you should bear in mind that the jackpot will not always reach so high. For this reason, it is also useful to know the average payout figure. Also, the average time between payouts is a good indicator of how long a current jackpot is likely to build before it is won. You can see a breakdown of this information in the following tables.
| Jackpot Game | Current Jackpot | Highest Jackpot | Average Win | Average Duration |
|---|---|---|---|---|
| Mega Fortune Dreams | £ 2,802,853.30 | £ 2,160,300.00 | £ 2,160,300.00 | 20 weeks |
| Mega Fortune | £ 1,942,373.00 | £ 17,861,800.00 | £ 4,212,042.00 | 11 weeks |
| Hall of Gods | £ 1,603,908.46 | £ 7,820,888.00 | £ 5,428,073.00 | 24 weeks |
| Arabian Nights | £ 207,406.60 | £ 8,636,041.00 | £ 4,237,240.00 | 71 weeks |
| Cosmic Fortune | £ 98,307.00 | £ 0.00 | £ 0.00 | 0 weeks |
| Jackpot Game | Current Jackpot | Highest Jackpot | Average Win | Average Duration |
|---|---|---|---|---|
| Mega Moolah | £ 3,559,109.67 | £ 13,230,200.00 | £ 4,300,555.00 | 17 weeks |
| Mega Moolah Isis | £ 3,493,404.25 | £ 13,230,200.00 | £ 4,300,555.00 | 17 weeks |
| King Cashalot | £ 2,225,013.20 | £ 1,527,228.00 | £ 568,880.00 | 63 weeks |
| Major Millions | £ 375,397.42 | £ 1,801,517.00 | £ 528,961.00 | 10 weeks |
| Tunzamunni | £ 80,116.25 | £ 479,534.00 | £ 311,522.00 | 89 weeks |
The Mega Moolah jackpot can also be won in several other slots from Microgaming. These include the spin off games Mega Moolah Summertime, Mega Moolah Isis and Mega Moolah 5 Reel Drive, plus the Batman-themed jackpot slot The Dark Knight. There are 4 different sized jackpots which can be won in the games.
The smaller jackpots, Mini and Minor are often cracked (sometimes even several times a day). The Major Jackpot is usually an impressive 5 figure sum. Yet it is the Major Jackpot which is the most appealing of all. This is always guaranteed to be a minimum of 1 million. Which of the jackpots you win is decided within the wheel of fortune bonus game.
| Jackpot Game | Current Jackpot | Highest Jackpot | Average Win | Average Duration |
|---|---|---|---|---|
| Jackpot Giant | £ 6,414,047.86 | £ 5,890,360.00 | £ 5,890,360.00 | 25 weeks |
| Beach Life | £ 2,717,968.20 | £ 6,215,470.00 | £ 2,560,693.00 | 24 weeks |
| Funky Fruits | £ 2,502,031.08 | £ 2,164,007.00 | £ 1,584,428.00 | 14 weeks |
| Gladiator | £ 883,026.60 | £ 2,374,806.00 | £ 1,033,670.00 | 12 weeks |
| Sweet Party | £ 774,389.66 | £ 3,004,916.00 | £ 1,199,633.00 | 15 weeks |
| Monty Pythons Spamalot | £ 8,119,535.44 | £ 2,710,257.00 | £ 1,537,205.00 | 61 weeks |
| Age of the Gods | £ 156,189.68 | £ 972,723.00 | £ 553,769.00 | 8 weeks |
| Gold Rally | £ 82,658.30 | £ 4,690,025.00 | £ 713,621.00 | 6 weeks |
From these lists of the biggest jackpot slots, just 1 did not quite reach the million-pound payout record – the Age of the Gods Progressive Jackpot. However, I have included it here because of the huge popularity of these slots. In fact, the Age of the Gods games include 4 different jackpots which can be won.
The largest, the Ultimate Power jackpot is listed here, but there is also the Power, Super Power and Extra Power jackpots that can be won. The other jackpots are smaller amounts, but they are paid out far more regularly. The smallest of the four, the Power jackpot is won roughly every 30 minutes.
Another interesting point regarding progressive jackpots is that some are connected through multiple games. This is the case with the Age of the Gods jackpot. No matter which character’s slot you choose to play, be that God of Storms, King of Olympus, or any other, a portion of the money bet on each game in the collection contributes towards the progressive jackpot prize fund. Another such example is the Microgaming slots Mega Moolah, Mega Moolah Isis and The Dark Knight, as mentioned above.
These slots also have pooled jackpots, meaning that the jackpot prize is not only built by play at numerous games, but also at many of the top online casinos in the UK that offer them. This results in the jackpots building to bigger amounts at a faster rate.
It is not just NetEnt, Playtech and Microgaming who provide jackpot slots. There are other, smaller providers who also offer slots with jackpots. Many of their jackpots are relatively small, yet there are some exceptions, where big prizes can be won. You can see 3 of the biggest jackpot slots from these other providers here.
| Provider | Slot | Current Jackpot | Highest Jackpot | Average Win | Average Duration | winnable at |
|---|---|---|---|---|---|---|
| Random Logic | Millionaire Genie | £ 1,438,229.00 | £ 4,671,110.00 | £ 2,264,660.00 | 26 weeks | 888Casino |
| IGT | MegaJackpots | £ 517,185.75 | £ 2,578,737.00 | £ 1,306,495.00 | 24 weeks | duelz |
| Cryptologic | Millionaires Club | £ 2,965,449.94 | £ 5,898,352.00 | £ 2,052,746.00 | 25 weeks | Duelz |
The IGT MegaJackpots is another example of a pooled jackpot. It can be won by playing a variety of slots, including the MegaJackpots versions of Cleopatra, Siberian Storm, Monopoly and Isle O’Plenty.
Slots with Incredibly High Payouts
Big wins are not exclusive to jackpot slots. The best-paying online casinos usually feature games with more significant potential payouts. To work out the highest possible payout, you generally take the highest paying symbol and multiply it by the number of paylines. Yet, there are various other factors which can affect the maximum payout.
These include the various types of bets per spin, bets per payline and betting levels. What’s more, the inclusion of free spins, wilds, bonus rounds, multipliers and so on can all impact on the maximum possible win. Therefore, it is not always clear at first glance what the maximum potential payout of a given slot is.
For the following examples, some calculations were needed to ensure that a fair comparison could be made between various slots. The following examples show the potential winnings for a £1 per spin bet, with all paylines activated. For the calculation, it is assumed that the spin reveals the highest paying symbol (excluded wild and scatters) on all positions on the reels during normal play, free spins and features.
| Slot | Software Provider | Max Win for £1 Spin with Free Spins | Maximum Bet | Max. Theoretical Win |
|---|---|---|---|---|
| Gonzo’s Quest | NetEnt | £825,000 | £200 | £165 million |
| Great Blue | Playtech | £180,000 | £50 | £9 million |
| Immortal Romance | Microgaming | £202,000 | £30 | £6.06 million |
| Gladiator | Playtech | £180,000 | £1,250 | £225 million |
| Starburst | NetEnt | £2,000 | £100 | £200,000 |
| Sparks | NetEnt | £400 | £400 | £160,000 |
Great Blue – with Plenty of Free Spins and Big Multipliers to Boost your WinningsRTP: 94.25%Manufacturer: –This slot from the iGaming giant Playtech has huge potential payouts. The shark and turtle symbols provide the largest payout, at up to 750x the line bet. What’s more, if a wild symbol is included in the line win, the payout is doubled. The game has 25 paylines, so a bet of 4p per line is needed to total £1 per spin, or the equivalent in your local currency. If the highest payout of 1500 is achieved on each of the paylines, that creates a maximum possible payout of £1500 per spin. Then when you consider the free spins and multipliers the outlook is even more rosy. The bonus round is launched when 3 oysters appear on the reels. Here you pick shells which will reveal a hidden number of additional free spins, or a win multiplier. The most lucrative combination is the x15 multiplier, which comes with a maximum of 8 free spins. So if the highest payout symbols cover the reels on each of the free spins, this means a maximum theoretical payout of £180000, for just a £1 spin. You will find this slot in virtually all Playtech casinos, like Duelz.
Immortal Romance – with 4 Level Bonus Game RTP: 96.8%Manufacturer: –Another popular slot with higher than average maximum possible payouts is Microgaming’s Immortal Romance. This vampire-love story themed game has 243 ways to win. It is not possible to place a bet of £1 – or equivalent – per spin, as the minimum bet per spin is 30p, and this increases in increments of 30p up to a maximum of £60. To ensure a fair comparison, I have converted the maximum payouts as if a £1 per spin bet is possible. After the scatter and wild symbols, the symbol with the next highest payout value is Sarah. With a theoretical bet of £1 per spin, a full screen of the Sarah symbol will result in a payout of £4050. When you get 3 scatter symbols anywhere on the reels, the Chamber of Spins bonus round is activated. The bonus rounds allow for even bigger payouts. There are 4 different levels to the bonus game. The first time the bonus game is triggered, you get 10 free spins with a 5x multiplier. This means you could theoretically win a maximum of £202000 in this round. Subsequent levels of the bonus round are unlocked the more times the bonus game is triggered. Each has its own features, including more free spins and different multipliers. Therefore, this maximum payout could reach even higher in the later bonus levels. However, that figure cannot be accurately determined, as further free spins can be won during the highest bonus round.
Gladiator – Enormous Payout Potential Even without a Progressive Jackpot RTP: 94.09%Manufacturer: –
There are 2 variants of Gladiator, one with a progressive jackpot and one without. As we have already seen the jackpot version above, here I refer to the non-jackpot version of the game. The game has 25 paylines, and you can place bets of between the equivalent of 25p and £1250 per spin. The highest paying symbol is the emperor Commodus, with a payout of x5000 for 5 symbols. Therefore, a £1 bet where the whole game screen is filled with the symbol will result in a maximum payout of £5000. The game also features the Coliseum bonus round, which is triggered by 3 scatter symbols. Here, you can win up to 12 free spins with up to a x3 multiplier. Therefore, the highest payout you can theoretically achieve in the bonus game is £180000. If you fancy trying your chances of pocketing the big potential payouts in this game, you can play it at William Hill Casino.
Gonzo’s Quest – with Increasing Multipliers for Big WinsRTP: 96%Manufacturer:–Gonzo’s Quest was one of the first to use the innovative NetEnt Avalanche feature. This sees symbols fall into place, rather than spinning. Every time you get a winning combination, the symbols explode, and new ones fall down to replace them. This can create numerous wins from just one spin. What’s more, with every consecutive win, the multiplier is increased, up to a maximum of x5. There is also a free spins bonus round, or free falls as they are called here, where the win multiplier can reach as high as x15.
The coin value can be set between 1p and £2 or the same in your country’s currency, plus, there are 5 different bet levels to choose from. This allows bets of between 20p to £200 with all 20 paylines activated. For the purpose of our comparison, a coin value of 5p, at bet level 1 enables a £1 per spin bet with all paylines covered. The highest valued symbol pays out x2500 the line bet, so if this symbol appears on all positions on the reels, the maximum payout for a £1 spin would be £2500. However, you then need to take into account the increasing multiplier of subsequent wins with the avalanche feature. The highest multipliers occur during the free spins round, with an increasing value with each avalanche win of x3, x6, and a maximum of x15. Therefore, the maximum payout of a £2500 win with all of these multipliers (a total of x33), is £82500 per free fall. The bonus round awards 10 free spins, so this means the highest theoretical payout is £825000.
Conclusion – Massive Payout Potential from the Major Game Providers
If you want to play for really big money, the progressive jackpot slots from Playtech, Microgaming and NetEnt are top choices. There are plenty of games where payouts can exceed a million. Within the game collection of these major software developers, you can find some enormous maximum potential payouts. Of course, you need to bear in mind that these games with higher maximum wins payout less regularly, or you may only see small wins whilst playing. But still, since we are looking for the games with high payouts, this is a drawback we are willing to accept.
