Online Slots with the Biggest Payouts

If you want to win big money playing slots, and let’s face it, who doesn’t, then there are a couple of options open to you. You can play slot machines with progressive jackpots, or opt for those slots that have higher than average potential payouts. On this page, you’ll find out everything about both options. Not only will you see the slots with the biggest jackpots online, you will also find a list of the games where you can win the largest amounts of money.

Overview of the Largest Online Jackpots

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 £1 million each.

£ 19,997,659.85 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 (£13.21m) win only just broke the previous record of €17.8 million (£13.19m), 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 Million Pound 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.

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.

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.

Bets on any Age of the Gods Slot at All Playtech Casinos Contribute Towards the Progressive Jackpot

These slots also have pooled jackpots, meaning that the jackpot prize is not only built by play at numerous games, but also at the many casinos 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.

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. There are some games that provide huge potential payouts, much higher than many others. In order 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.

The Highest Payouts of Different Online Slot Games
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. 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 Ladbrokes.

With 243 Ways to Win, Microgaming’s Immortal Romance Slot Provides Huge Potential PayoutsImmortal 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 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:

Gladiator Slot from Playtech Offers Higher than Average PayoutsThere are 2 variants of this slot, 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 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.

The Innovative Gonzo’s Quest from NetEnt Provides Highest Theoretical PayoutsGonzo’s Quest – with Increasing Multipliers for Big WinsRTP: 96%Manufacturer:This game 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, 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.

An Overview of some Slots with Average Payouts

One of the most popular slots in the UK is NetEnt’s Starburst. It has 10 paylines, with wins paid both ways. There are 10 bet levels and an adjustable coin value of between 1p – £1. Therefore, a coin value of 10p at bet level 1 will allow for a £1 spin with all paylines covered. The highest paying symbol is the golden bar, with a x250 payout for 5 matching symbols on a payline. So if the entire screen is covered with this symbol, a maximum payout of £500 will be made, given that the payout will be made for right to left wins, as well as the usual left to right wins. This already looks pretty low compared to many other slots. Of course, free spins and bonus rounds must also be taken into consideration when determining the absolute maximum theoretical payout. In this game, a Starburst Wild symbol can appear on reels 2, 3 or 4. This symbol expands to cover the entire reel, and triggers a re-spin, with a maximum of 3 re-spins possible. Yet this will result in an absolute maximum payout of £2000 if all positions continue to display the bar symbol on all 3 subsequent re-spins. Compared to many other slots, this is a relatively small maximum payout.

Payout Rates for Popular Online Slots
Slot Game Software Provider Max. Bet Return to Player Rate (%)
Big Bad Wolf Microgaming £125 97.35
Jack Hammer 2 NetEnt £250 97.1
Reel Rush NetEnt £100 97
Wild Gambler Playtech £100 97
Guns N Roses NetEnt £200 96.98

Another popular game from NetEnt is Sparks. Here, you can choose between one way wins, or both ways. There are a total of 20 paylines, so a £1 spin would require a coin value of 5p. The highest paying symbol is the red spark. In win both ways mode, the payout is x200 for 5 symbols on a payline. Playing in win one way mode, the payout is x400. Therefore, regardless of which mode you choose to play, the maximum you can win for a £1 spin is £400. The game does not have any special features such as free spins, bonus rounds or multipliers, therefore, this is the absolute maximum payout potential for a £1 spin. Clearly, this is rather low compared to those we looked at previously. Plus, there are numerous NetEnt slots that offer much higher than average payouts than Sparks.

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 pounds. Yet it is not just jackpot slots that provide the opportunity to win big. 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 where you can win enormous amounts, this is a drawback we are willing to accept for this comparison.
