What is a Jackpot Slot?

If we want to explain what jackpot slots are, first we have to clarify what a jackpot is.

In short, jackpots, also known as grand prizes or payouts are the monetary rewards given to players who stake and win at online slots and other games of chance (online bingo, online lottery etc.).

Depending on the slot type, the maximum jackpot amount awarded can vary. You can either get:

  • a fixed sum determined by the game manufacturer/software provider (in the case of regular slots like Starburst or Wolf Gold).
  • a variable sum that grows exponentially the more stakes are placed by the players (in the case of progressive jackpot slots such as Mega Moolah).

However, what is important to know is that a single game can offer more than one jackpot type.

Most online slots integrate multiple jackpots of different values, with suggestive names such as “mini” or “maxi jackpot”, increasing the player’s chances of acquiring at least one.

 

Who Can You Play Jackpot Slots?

Anyone who is of legal gambling age (18 years old) is allowed to play online jackpot slots.

The most important aspect to remember when playing is that you have to wager real money to win real money.

If you’re playing the demo version of a jackpot slot, since you will be using bonus credits, you can’t cash out real money. Even if you win the jackpot, it’ll be nothing more than numbers on a screen or a “paper win.”

 

How Do Jackpot Slots Work?

If, in the case of fixed jackpots, things are pretty straightforward, understanding how progressive jackpots work can be a bit more difficult.

A good analogy to keep in mind is a group of friends all chipping in for dinner – you can think of progressive jackpots as crowd-funded prize pools that get bigger with every individual player contribution.

To make things easier for you, many casinos also have a live countdown displayed for some of their best progressive jackpots – that will help you gauge whether the maximum amount has been reached or not and what is the current value of the jackpot.

Some casinos also have „overdue indicators” which signal to the players that a jackpot is due to be hit soon.

However, you should take these indicators with a grain of salt since, most often than not, they have no statistical relevance. In other words, they won’t tell you for sure when and how to win jackpot on online slots, but are merely tools used by the casino to keep you staking or coming back for more.

If you just won a jackpot, no matter what type it is, ideally, cashing out should be just as straightforward. Your earnings should be eligible for withdrawal as soon as you’ve been crowned winner.

Keep in mind that, in the case of a very large jackpot win, some casinos may not pay you the entire amount up front, but in fixed incrementals, due to their maximum withdrawal limits.

 

Why Should You Play Jackpot Slots?

There are many reasons why you should consider trying your luck at jackpot slots online:

  • The potential for life-changing wins – statistically-speaking, of all casino games, it’s progressive jackpot slots that have turned the most regular people into millionaires.
  • You don’t have to bet a lot to win a lot – in fact, if we go by statistics once again, the biggest winners in history have only bet a few pennies. Most modern jackpot slots have very accessible minimum bets (e.g. €0.20 per spin).
  • Multiple chances to win – if lottery only gives you one shot per ticket to be the lucky winner in a random draft, a jackpot game gives you more chances to try per single game session, as you get to decide and control the number of jackpot spins based on your budget (for example, some jackpot slots have a minimum spin of $0.10, meaning that just $10 will buy you 100 games).
  • There is a jackpot for every player type – if you’re not an adrenaline-seeker, you can always go for fixed jackpots (EGT is solid choice if you’re after non-progressive prize pools accessible to every pocket – Shining Crown, 40 Super Hot, 40 Burning Hot etc.).
  • Thematic diversity – gone are the days of rudimentary, fruity slot machines, nowadays jackpot slots come in all shapes and sizes and it’s impossible not to find one to your taste (you can find titles inspired from Norse, Greek or Egyptian mythology, movie-themed slots, adventure and fantasy slots etc.).
  • They are fun – perhaps not the strongest argument, but it’s still a valid one: modern jackpot slots have state-of-the art mechanics, special symbols and bonus features, as well as 3D visuals and realistic sound effects, creating the perfect cocktail to stay entertained for hours.

 

How to Win at Jackpot Slots

Contrary to popular belief, jackpot slots can’t be rigged or manipulated because they have pre-set payout rates and house edges. Since most quality modern jackpot slots use RNG technology (Random Number Generator), a win will always be triggered randomly, following the rules of probability.

The odds of winning at jackpot slots are similar to those of winning the lottery, what differs is that online slots allow you to have multiple game sessions, whereas lottery games are organized less frequently.

Smaller jackpots will always give you better odds to win than larger ones and that has a lot to do with the varying levels of volatility and the theoretical pay rates programmed into the slot machine or online game by the manufacturer. Although you can’t manipulate these odds, there are steps to take and strategies to increase your chances of winning.

Strategies for Winning Jackpot Slots

If you organize your next game session and plan ahead, you can improve your chances to win, even when the odds seem stacked against you. Here’s how:

  • Understand the slot you’re playing – because your odds of winning the best jackpots depend on your thorough understanding of the game mechanics, reels, special symbols and how to use the bonus rounds to your advantage, your best bet is to always play free slots and build your strategy risk-free.
  • If the jackpot has been won recently, skip that slot – once a jackpot has been won, the prize pool resets itself and your odds to win decrease, which is why you should go for the game that hasn’t paid out in a while, instead of the one that just made a millionaire.
  • Create an entire budget dedicated only to jackpot slots – never risk playing with money you don’t have and stick to the budget you set for yourself. If you play more than one casino game (poker, roulette, slots), it would be wise to separate your budget into categories.
  • Decide what jackpot you’re going for and bet accordingly – for example, if you’re aiming for frequent, consistent but smaller wins, you should keep your stakes low, if you’re after the big bucks, you should bet more, preferably on all paylines. If you want to extend your game session, you should keep your betting range conservative so you don’t burn through your budget too fast. As a general advice – don’t chase your losses. If you have a losing streak, it’s best to stop playing for a while.
  • Follow the average time between payouts – this is a good indicator to keep in mind to determine when it’s likely for a jackpot to be hit again, especially in the case of jackpot slots that pay out at similar intervals over the course of a year (for example, the Hall of Gods jackpot is hit roughly every 24 weeks, Mega Moolah’s jackpot is hit every 17 weeks and King Cashalot’s jackpot is hit approximately every 63 weeks).

 

Types of Jackpots at Online Slots

Irrespective of the title chosen or the casino you play at (local or international), a jackpot game should award at least one of the following jackpot types:

  • Classic or fixed jackpot – this jackpot is awarded for regular or non-progressive slots, meaning that its value is already set and it can’t be changed in any way (it doesn’t matter how often a player wins or if they wagered $5 or $10, the jackpot amount will always have a predetermined maximum level – e.g.: 2000x your stake).
  • Progressive jackpots – at the opposite end, in the case of progressive jackpot slots online, the jackpot increases by a small amount every time the game is played, even if the jackpot is not won. There are two main types of progressive jackpots – stand-alone progressive (prizes are awarded at only one game or slot machine and they are not connected to any others) and wide area progressive jackpots (multiple games are connected across various casinos that use the same software, resulting in much larger prize pools, usually in the 6-figure range).
  • Seasonal jackpots (daily/weekly/monthly) – these are in-house jackpots, only awarded by a particular casino as part of a special promotion. They can be granted at one game or multiple games from the same provider (e.g. Microgaming or Netent slots tournaments with weekly jackpots).
  • Mystery jackpots – one of the most exciting jackpot types out there, its maximum value is usually controlled by the casino and multiple games participate in the prize pool. The total jackpot amount is usually disclosed in the form of an approximation or interval – e.g.: between $2000 (lowest end) to $5000 (highest end).
  • Exclusive jackpot – similarly to seasonal jackpots, exclusive jackpots are also unique to a particular operator or game. What differs, however, is that some exclusive jackpots are usually given only to select player categories such as VIP customers or high rollers.

 

What Is a Progressive Jackpot Network?

Multiple local and networked (or pooled) jackpot games are organized in what is called a progressive jackpot network.

A small percentage of every bet placed in the network counts towards the jackpot, usually between 1 to 5%.

What a progressive jackpot network does, essentially, is share jackpots across multiple casinos so that the maximum jackpot amount can grow more rapidly every time a single player or a group of players wager at the same time from a different location.

Because these partner casinos are interconnected, they will also typically utilize the same software.

For example, the largest progressive jackpot network in the world belongs to Microgaming, having paid out over €1 billion to date.

Although other types of casino games are also included in the network, historically, it’s progressive jackpots that have paid out the most – Mega Moolah, Mega Moolah Isis and Major Millions.

Netent’s wide area progressive network is the second most profitable worldwide. The provider has given us some of the best progressive jackpots out there – Mega Fortune, Hall of Gods, Arabian Nights and Divine Fortune, all awarding legendary, Guinness record-worthy wins.

 

Top 10 Most Played Best Jackpot Slots Worldwide

#1 Mega Moolah

Mega Moolah Slot

Mega Moolah, also known as „Millionaire Maker” in player communities is, by far, Microgaming’s most popular title and offers one of the best jackpots. And there are many reasons why this 5-reel, 3 row slot is so well received – featuring 25 adjustable paylines and low stakes between £0.01 to £6.25 per spin, anyone can try their luck at becoming a millionaire.

Although its RTP is lower than average (88.12%), it still hasn’t stopped this slot from awarding record wins throughout its existence. That is because it compensates the low RTP by offering 4 progressive jackpots – Mini, Minor, Major and Mega, and a free spins feature.
Mega Moolah was launched on the 28th of November 2006, but it managed to maintain its appeal for over a decade and it’s still a player favourite in 2021.

RTP, Variance, Volatility and House Edge Explained

RTP, also known as Return-To-Player, is the average percentage that is paid out to the player in the form of a win relative to the total amount he wagered.

No casino game can have an RTP score of 100% because that would mean the player always wins and the house always loses.

You can look at the house edge as the advantage the casino always holds over its players or the percentage of the total bets the casino always gets to keep.

As we mentioned previously in the article, most online slots and slot machines have an RTP of 95%, meaning that the house will always have a 5% advantage over you.

Roulette is, perhaps, an even better game to explain house edge. There is a reason why most players avoid American Roulette and go for European Roulette, instead, and that is because the former has a house edge of 5.26% and the latter of only 2.7%.

Variance and volatility can be considered synonymous terms, since they both refer to how often a slot pays out jackpots, but also how much those jackpots are usually worth.

For example:

  • Low and medium variance slots offer small to medium sized wins pretty frequently.
  • High variance slots offer rarer wins, so you have to play a lot to come by one, but when a win gets triggered, it’s usually substantial.

 

Jackpot Slots – Key Terms to Understand

When you’re first trying to play these types of games, it can get pretty overwhelming, especially if you don’t understand the technical terms. As always, we’re here to simplify your journey:

  • Branded jackpot slots – these are jackpot slots based on popular franchises (TV shows, series, movies) or celebrities (e.g.: Jimi Hendrix, Guns N' Roses, Ozzy Osbourne, Deal or No Deal etc.).
  • Proprietary jackpots – these are jackpots that you can typically find only at a particular casino. 888, for example, is famous for this, offering very high jackpots at exclusive titles like Gods of Gold, Once Upon a Dime, Happy Faces Jackpot Slot etc.
  • Active payline – an active payline is one that has a bet placed on it. Depending on the jackpot slot you choose, some may have fixed paylines, meaning you have to bet on all of them, or flexible paylines, meaning you get to choose on which ones you bet.
  • Cold/Hot Jackpot Slots – these are two terms attributed to slot machines or online slots depending on their recent payout rate. The slots that haven’t paid out in a while are labeled „cold slots” whereas those that have been on a winning streak recently are called „hot slots”.
  • Instant Winner Jackpot Slot – this is the most sought-after slot type because, in the case of a lucky win, the entire sum is paid up front. The opposite of this term is „annuity winner” – in this case, players get paid in installments over months or years.
  • Primary Jackpot – this is a term used for online slots with multiple jackpots and it refers to the one with the highest value. The ones with lower value are typically referred to as secondary jackpots.
  • Big Hit – this is a term used when a player hits the jackpot combination on a slot.

 

Best Jackpot Slots Freeplay & Mobile

The best jackpot slots are available to play for free directly on the developer’s website (e.g. Yggdrasil, Playtech etc.) or at their partner casinos (you can trust these casinos to give you the best experience because they are endorsed by the developers themselves).

The newer jackpot slots are built using HTML5 technology, making them compatible by default with modern mobile devices and operating systems. Some older jackpot slots can bring some compatibility issues, especially if they use outdated Flash technology.

Some great casinos we recommend that either have a mobile-optimized platform, a mobile app, mobile slots or all of the above are:

  • Mansion Casino
  • 888 Casino
  • Spin Casino
  • Jonny Jackpot
  • Mr. Green

Lastly, when we talk about popular jackpot slots designed specifically for Android and iOS mobile devices, we also have to mention spin to win slots.

Easy to download and perfect for a smaller screen, these types of jackpot slots award players with hefty prizes ranging from $100 to $10 000 daily.

 

How to Choose a the Best Jackpot Slot

There are many criteria that go into choosing a jackpot slot, from subjective ones such as personal taste and attachment to a particular software provider, to more objective ones such as profitability.

Here are our objective criteria that we keep in mind when assessing jackpot slots:

  • RTP scores – fixed jackpot slots offer RTPs of 94-96%, meaning more frequent, but lower wins. Progressive jackpot slots, on the other hand, even if they have lower RTP scores (88-91%), still offer substantial prizes. Such is the case of Mega Moolah with an RTP of only 88.12% and an average jackpot of $1 000 000.
  • Historical payout – the historical payout is the average amount paid by a jackpot slot over a fixed period of time (e.g. 6-12 months). The higher it is, the more attractive and profitable the slot becomes. For example, Netent’s slot Arabian Nights pays an average of £1.4 million every 6 months.
  • Average jackpot value – this is the average value a jackpot hits over a fixed period of time, even without being claimed. For example, Playtech’s slot, Gladiator has an average jackpot value of $2 000 000.
  • Number of jackpots – some jackpot slots offer a single, substantial prize (e.g.: Cash Splash) or a couple of jackpots that increase in value progressively (e.g.: Mega Fortune offers 3 jackpots called Rapid, Major and Mega, worth £50, £5000 and £150 000).

How to Choose a Jackpot Casino

When choosing a jackpot casino, you need to first determine three things:

How to Choose the Best Jackpot Slots
  • Your risk tolerance level – some jackpot casinos have games with lower or higher volatility.
  • Your budget – this will help you determine your player type and see if a regular jackpot casino is the right choice or if you should look into high roller or VIP jackpot casinos.
  • Your goals – how much you want to win in one game session or over a set period of time.

After you’ve established your position on all of the above, you can also look into aspects such as:

  • Bonuses & Promotions – you want to choose an operator with a good reward system, preferably in the form of welcome bonuses, cash to recoup your losses and free spins granted at high paying jackpot slots.
  • Games selection – because every player’s risk level is different, once you determine yours, you want to go for a jackpot casino with games that fit your profile – e.g. progressive slots with high volatility or non-progressive jackpot slots with lower risk.
  • Game providers – a good jackpot casino should work with providers that are known for creating high-paying, fair jackpot games such as Microgaming, Netent, Yggdrasil, EGT or Playtech.
  • VIP perks – especially if you’re a high roller, your best bet is to go for a casino that actively rewards players like you (for example, operators like Jackpot City, Grand Ivy Casino, Playamo and Spin Casino).
  • RTP scores – the average RTP for regular slots is 95%, however, as we mentioned above, you shouldn’t be deterred by seeing lower RTP scores for progressive jackpot slots since that doesn’t translate into lower profitability.
  • Security, licensing and trust factor – always play at jackpot casinos licensed by known regulatory bodies such as UK Gambling Commission or Malta Gaming Authority, with good trust scores and player reviews.
  • Payment methods and limits – a good jackpot casino should offer at least 2-5 trusted payment methods such as credit and debit cards or e-wallets and the deposit/withdrawal limits should be in line with your player type (high if you’re a VIP customer or low/medium if you only play occasionally).

 

Where Can You Play the Best Jackpot Slots?

Most jackpot slots can be tried for free, as the demo version of the game is almost always available on the game developer’s website.

Best Software Providers for Jackpot Slots

Because competition is rampant in the iGaming industry, when creating the best jackpot slots, every software provider wants to have a signature touch (for example, EGT is the pioneer of classic, vintage fruity jackpot slots and Yggdrasil always draws inspiration from mythology).

Here are the best software providers that have revolutionized jackpot slots:
  • Microgaming – known for constantly delivering high quality games and jackpots, there aren’t many players who haven’t heard of their best jackpot slots Mega Moolah, Mega Moolah Isis, Major Millions, Cash Splash, Wow Pot! and Fruit Fiesta.
  • Netent – another top choice to go for, this provider is also known for creating millionaire-making jackpot slots such as Mega Fortune, Hall of Gods, Arabian Nights or Mega Fortune Dreams.
  • Playtech – this provider is known for addressing various themes in its slots, from mythology to movies and summer fun, whilst still delivering jaw-dropping prizes – for example Funky Fruits, Gladiator, Beach Life and Age of The Gods offer some of the best online jackpots you can go for, with an average payout of £1 000 000.
  • Yggdrasil – with jackpots that can reach up to €100,000 on average, Yggdrasil is another name to put on your radar – some of their best performing titles are Joker Millions, Empire Fortune, Jackpot Raiders and Ozwin’s Jackpots.

Other lesser-known game providers that offer substantial jackpots are IGT and Cryptologic.

For example, IGT’s title Mega Jackpots offers a pooled jackpot of up to £1 000 000 that gets claimed roughly every 24 weeks.

Cryptologic, one of the oldest game providers in the industry, also offers a very profitable gem – Millionaires Club, a slot with a jackpot that frequently passes the £2 000 000 mark.

 

Most Impressive Jackpot Slot Wins in History

Although, as much as we’d all like it, there’s no such thing as a fixed recipe on how to win jackpot online slots, some people have still managed to defeat all odds and take home jaw-dropping prizes, sometimes by betting no more than a few cents.

Here are some amazing jackpot casino winners that might inspire you to try your luck, too:

Best Jackpot Slot Winners

  • Norwegian Come On! Casino Player – won €7,525,932.97 on the 15th of June 2017 at Netent’s Hall of Gods.
  • British Soldier Wins on Betwaywon £13,213,838.68 with a 25p stake at Microgaming's Mega Moolah, becoming a multimillionaire overnight.

  • Kingdoms Rise: Battle Beast – launched on the 6th of March 2021, this fantasy-themed Playtech gem offers 4096 betways, a generous RTP of 96.22% and three massive jackpots worth 10 000x your stake – Epic Jackpot (a progressive jackpot starting at £100,000), Power Strike Jackpot (a fixed jackpot that drops when an established limit is hit) and Daily Strike Jackpot (a jackpot you can hit daily at a set time).
  • El Dorado: Infinity Reels – launched on the 4th of March 2021 by Yggdrasil, this Mayan-themed video slot is packed with great features, including free spins and expanding reels. A juicy jackpot can be activated at any point in the game that adds a multiplier of 888x to your bet.

 

Alternatives to Jackpot Slots

If jackpot slots simply aren’t your bread and butter, even after reading all of the above, don’t worry. There are plenty of other casino games that offer equally high payouts:

  • Blackjack – whether you play online or against a real dealer, both options have a huge win potential, with some blackjack variants offering RTPs of up to 99.5% (e.g. Pontoon, Atlantic City Blackjack, European Blackjack).
  • Video Poker – this classic card game requires both luck and skill to get the big bucks, however, some video poker variations are more profitable than others – for example, Jacks or Better has a jaw-dropping RTP of 99.56%.
  • European Roulette – this roulette type has a better house edge (2.7%) compared to its American counterpart (5.25%), meaning that its average RTP is 97.3% on every spin of the wheel (not too shabby, right?).
  • Craps – with an average house edge of only 1.41%, this casino classic is known for offering some of the best odds to players.

 

Best Jackpot Slots Summary

Some key takeaways that you need to remember is that jackpot slots can be split into two broad categories – progressive and non-progressive.

The best progressive jackpots grow by a small percentage with every player bet, whereas non-progressive slots have a capped maximum win.

Netent and Microgaming own the two largest progressive jackpot networks in the world, with titles like Mega Fortune and Mega Moolah consistently paying out millions.

Some of the best jackpot slots out there have made millionaires out of pennies, so you don’t always need to bet a lot to win a lot.

Lastly, although this is a very popular myth, the best jackpot slots can’t be rigged because they use RNG technology (Random Number Generator) that ensures random odds and wins every game session.

 

Best Jackpot Slots FAQs

❓ What are jackpot slots?

They are a slot type characterized by high prize pools, very often in the 6-figure range.

❓ Where can you find the best jackpot slots?

You will always find the best variety if you play at casinos that make jackpot slots a central part of their offer (some examples are Spin Casino, Jackpot City and SlotsMillion).

❓ What is the highest paying jackpot slot?

If we go by statistics and actual wins recorded, then Microgaming’s slot Mega Moolah is the clear winner and one of the best jackpot slots, consistently paying high value, six-figure jackpots. The game also holds a Guinness World Record for the biggest progressive jackpot win in history.

❓ Do you need a high stake to hit the jackpot at an online casino?

It depends on the slot. In some cases, higher stakes don’t necessarily increase your chances of winning, they only ensure that, when you do get a payout, it’s larger in cash value. Historically, there have been huge wins from bets smaller than €1 and there are many quality jackpot slots that allow you to play with minimum stakes.

❓ What is a progressive jackpot slot?

It’s a type of slot whose jackpot increases progressively with the number of players betting on the game, as a small amount of every stake goes towards the jackpot total.

❓ Can I play jackpot slots for free?

Yes. Some of the best jackpot slots are available on the software developer’s official website for free (for example Netent.com or Playtech.com) or at their partner casinos.

❓ Can I play jackpot slots for free?

Yes, if the casino you’re playing at is mobile optimized or has a mobile gambling app and the jackpot slot you want to play is compatible with mobile devices. Older jackpot slots use outdated technology, so they might bring compatibility issues but you should have no problem playing modern ones on tablets and smart-phones with iOs and Android.

❓ Which casinos are the best for jackpot slots?

Admiral, Netbet and Mr. Bit are great for classic, fixed jackpot slots because they work with providers specializing in these types of jackpots – EGT and Novomatic. For progressive jackpots and higher payouts, we recommend looking into casinos that offer more titles from providers like Microgaming and Netent (e.g.: Frank Casino, 888, Party Casino, Bistarz or Jackpot City).

❓ Are online jackpot slots rigged?

If you’re playing at a reputable casino whose games are verified by trusted, independent auditors like eCOGRA, then no. In fact, it would be impossible for any jackpot to be rigged or for a third party to temper with the way you win slots online, since quality games use Random Number Generator Technology (RNG).

❓ How do I trigger the jackpot at an online slot?

There is no guaranteed way of triggering the jackpot at a given time. You can, however, track the jackpot’s live value, RTP rate and estimated payout times (if, statistically, a particular slot tends to pay out every 36 weeks, you should play as close to that date as possible).

❓ What is a loose slot?

A loose slot is one that pays out more frequently and offers above-average wins. At the opposite end, a tight slot is one that pays less frequently and offers a lower RTP rate.

❓ What is a fixed jackpot?

It’s a type of jackpot that is capped to a fixed maximum sum and doesn’t increase with the player’s bets. That is exactly why it’s also called a non-progressive jackpot.

❓ How often are jackpots won at online casinos?

If we could know in advance, every player who staked at the best jackpot slots online would exit the game session a millionaire. However, based on past occurrences and RTP, you can estimate your odds – smaller jackpots tend to be hit more often throughout the year, whereas large, 6-figure jackpots usually come only once a year.
