Top 10 Jackpot Slots in 2021
What Is a Jackpot Slot?
If we want to explain what jackpot slots are, first we have to clarify what a jackpot is.
And, because we know you’re just as fired up for big wins as we are, we invite you to read on.
Let’s get started.
Depending on what slot you’re playing, you can get a different maximum jackpot amount:
- A fixed sum determined by the game manufacturer/software provider (as 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 (as in the case of progressive jackpot slots such as Mega Moolah).
The key takeaway is that a single game can offer more than one jackpot type.
In other words, you can get rich, filthy rich – or both! Yes, you’ve read that right.
Most online slots integrate multiple jackpots of different values, with suggestive names such as “mini” or “maxi jackpot”. As such, your chances of taking home at least one increase, too.
Who Can Play Jackpot Slots?
Anyone who is of legal gambling age (18 years old) is allowed to play online jackpot slots.
Makes sense, right? We’d love to tell you the opposite but, in the gambling world, there’s no such thing as a free lunch.
In fact, if you’re playing the demo version of a jackpot slot, since you use bonus credits, you can’t cash out real money.
Even if you do win the jackpot, it’ll be nothing more than numbers on a screen or a “paper win”.
How Do Jackpots Work?
If fixed jackpots are pretty straightforward, understanding how progressive jackpots work can be a bit of a challenge.
But don’t worry, we’re here to break it down for you.
Here’s a good analogy to remember – a group of friends all chipping in for dinner.
To make things easier for you, many casinos also have a live countdown displayed for some of their best progressive jackpots. This is meant to help you gauge if the maximum amount has been reached or not, and what the current value of the jackpot is.
Some casinos also have ‘overdue indicators' which signal to the players that a jackpot is due to be hit soon.
However, our advice is to take these indicators with a grain of salt – most often than not, they have no statistical relevance.
In other words, they won’t tell you for sure when and how to win the jackpot on online slots.
But it also makes sense – there’s no such thing as a free lunch, as we mentioned.
These are merely tools used by the casino to keep you staking and coming back for more.
And, if you do, and you trigger that sweet win, is there really anything else you need to know?
Just keep in mind two small details:
- If you just won a jackpot, no matter what type, cashing out should ideally be just as straightforward. Your earnings should be eligible for withdrawal as soon as you’ve been crowned winner.
- In the case of a very large jackpot win, some casinos may not pay you the entire amount up front, but in fixed increments, because of their maximum withdrawal limits.
Why Should You Play Jackpot Slots?
Are you on the fence about trying your luck at jackpot slots online?
Below are a few things that may clear up any doubts you still harbour:
- The potential for life-changing wins – 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 – 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). Encouraging, right?
- Multiple chances to win – A jackpot game gives you plenty of chances to win in a single game session. In some cases, only $10 will buy you 100 games. Yes, you’ve read that right – $10 can actually change your destiny!
- There is a jackpot for every player type – If you’re not an adrenaline-seeker, you can always go for fixed jackpots from providers like EGT – e.g. Shining Crown, 40 Super Hot.
- Thematic diversity – Jackpot slots come in all shapes and sizes (e.g. movie-themed, adventure, mythology, fantasy slots and others), so it’s impossible not to find one to your taste.
- They are fun – Modern jackpot slots create the perfect cocktail to keep you entertained for hours (state-of-the art mechanics, special symbols, bonus features, 3D visuals and more).
How to Win at Jackpot Slots
Most quality modern jackpot slots use RNG (Random Number Generator) technology.
This means a win always gets triggered randomly, following the rules of probability.
What differs is that online slots allow you to have multiple game sessions.
By contrast, lottery games are organised less frequently.
The explanation lies in the different levels of volatility and the theoretical pay rates.
These are programmed into the slot machine or online game by the manufacturer.
Sadly, you cannot manipulate these odds.
However, don’t get discouraged!
There are still steps to take to increase your chances of winning:
Strategies for Winning Jackpot Slots
To win or not to win? That is the question.
We always want our readers to take home those juicy prizes!
And, if you organise your next game session and plan ahead, you absolutely can.
Even when the odds seem staked against you.
- Understand the slot you’re playing – your odds of winning the best jackpots depend on your thorough understanding of the game mechanics, reels and special symbols.
- 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.
- Create an entire budget dedicated only to jackpot slots – if you play more than one casino game (poker, roulette, slots), separate your budget into categories.
- Decide what jackpot you’re going for and bet accordingly – if you’re aiming for frequent, but smaller wins, keep your stakes low; if you’re after the big bucks, bet more on all paylines.
- Follow the average time between payouts – some jackpot slots pay out at similar intervals during a year (e.g. the Hall of Gods jackpot is hit roughly every 24 weeks).
Types of Jackpots at Online Slots
Now, let’s get to the good part – how much can you win?
A jackpot game usually awards at least one jackpot type, such as:
- Classic/fixed jackpots – These are paid out at regular or non-progressive slots. Their value is already set and can’t be changed in any way.
- Progressive jackpots – These increase by a small amount every time the game is played, even if the jackpot is not won.
- Seasonal jackpots (daily/weekly/monthly) – These are in-house jackpots, only given by a particular casino as part of a special promotion.
- Mystery jackpots – Their maximum value is controlled by the casino, and multiple games participate in the prize pool.
- Exclusive jackpots – These are given only to select player categories, such as VIP customers or high rollers.
What Is a Progressive Jackpot Network?
If the previous info made you an even bigger fan of progressive jackpots, imagine what fun entire networks of these games would be!
Here’s how it all works:
- Multiple local and pooled jackpot games are organised in a progressive jackpot network.
- A small percentage of every bet placed in the network counts towards the jackpot (roughly between 1 to 5%).
- A progressive jackpot network essentially shares jackpots across multiple casinos.
- The end result? The maximum jackpot amount grows more rapidly, as groups of players wager at the same time from a different location.
Because these partner casinos are interconnected, they will also typically utilise the same software.
Although other 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.
The provider has given us some of the best progressive jackpots out there: Mega Fortune™, Hall of Gods™, Arabian Nights™ and Divine Fortune™.
All of the above have awarded legendary, Guinness record-worthy wins.
Pretty sweet, right?

Mega Moolah, also known as ‘Millionaire Maker' in player communities, is by far Microgaming’s most popular title.

Joker Millions is another top-notch progressive jackpot slot from Yggdrasil, with an elegant reel design and classic symbols – bells, the number 7, cherries and jokers.

Some of its most important features are the two progressive jackpots – Super Jackpot (375x your stake) and Grand Jackpot (500x your stake).
The game has a very dynamic and interactive feel to it, as the rhinos on the reels seem to charge towards the player just like they would do in the wild.

#8 Genie Jackpots Megaways™
Genie Jackpots Megaways™ is a lesser-known, but equally profitable jackpot slot created by Blueprint Gaming. With a maximum win of £250,000, it is definitely worth a spin.
It follows a 6-reel, 5-row structure and includes a Megaways™ mechanic, free spins rounds, locking Wild symbols and a Buy The Bonus special feature.

Aztec’s Millions is a progressive slot created by Realtime Gaming. Taking you on a wild ride to the land of the Aztec pyramids, it has all special features players love, from bonus games to a jaw-dropping jackpot.

#10 Holmes and the Stolen Stones
Holmes and the Stolen Stones is an adventure-themed video slot released by Yggdrasil, with a decent win potential and very-high quality visuals.
The Sherlock Holmes theme is bound to be a success with players who love solving a good mystery. Simply play detective by putting together all the clues and, of course, retrieving the stolen precious stones.
There are five separate progressive jackpots ranging from €40 to €10,000, and the declared hit frequency of the jackpot is 25.4%.
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 wagered.
No casino game can have an RTP score of 100%, because that would mean the player always wins and the house always loses.
Most online slots and slot machines have an RTP of 95%, meaning that the house will always have a 5% advantage over you.
- Low and medium variance slots offer small- to medium-sized wins frequently.
- High variance slots offer rarer, but more substantial wins.
Jackpot Slots – Key Terms to Understand

- Branded jackpot slots – These are based on popular franchises (TV shows, series, movies) or celebrities (e.g. Jimi Hendrix, Guns N' Roses, Ozzy Osbourne, Deal or No Deal and so on).
- Proprietary jackpots – Found only at a particular casino. 888casino is a good example here, famous for their high-exclusive jackpots – e.g. Gods of Gold, Once Upon a Dime.
- Active payline – A payline with a bet placed on it.
- Cold/Hot Jackpot Slots – Slots that haven’t paid out in a while are labelled ‘cold slots, whereas those that have been on a winning streak recently are called ‘hot slots'.

Jackpot Slots Freeplay & Mobile
Good news for mobile casino fans: playing on the go has never been easier!
Newer jackpot slots use HTML5 technology – they are compatible by default with modern mobile devices and operating systems. Older jackpot slots can cause compatibility issues if they use outdated Flash technology.
Some great casinos with a mobile-optimised platform, a mobile app, mobile slots or all of the above are:
Lastly, we can’t talk about popular mobile jackpot slots without also mentioning spin to win slots.
Easy to download and perfect for a smaller screen, these slots award you with hefty prizes ranging from $100 to $10 000 daily.
How to Choose a Jackpot Slot
Unlike school, any answer is the right answer here.
Allow us to explain.
If you like to go with your gut, you can base your choice entirely on personal taste or attachment to a software provider.
If you prefer to remain pragmatic, you can look at objective criteria that we also consider when doing our rankings, such as:
- RTP scores – Fixed jackpot slots have RTPs of 94-96%. Progressive jackpot slots, on the other hand, still offer substantial prizes even at a lower RTP score (88-91%).
- Historical payout – This is the average amount paid by a jackpot slot over a fixed period of time (e.g. 6-12 months).
- Average jackpot value – This is the average value a jackpot hits over a fixed period of time, even without being claimed.
- Number of jackpots – Some jackpot slots offer a single, substantial prize (e.g. Cash Splash) or a couple of jackpots that increase in value (e.g. Mega Fortune™).
Most Profitable Jackpot Slots
Ever wondered which jackpot slots have the best payout rates? Are you curious to also learn which have granted players the most explosive wins?
Look no further – here are our top jackpot slot picks if you’re looking for high returns:
How to Choose a Jackpot Casino
When choosing a jackpot casino, you need to first determine three things:
- 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 whether 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 – Always go for a casino with a good reward system (e.g. welcome bonuses, cash to recoup your losses and free spins at high paying jackpot slots).
- Games selection – Every player’s risk level is different, so 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 known for creating high-paying, fair jackpot games (Play’n GO, Red Tiger, Pragmatic Play).
- VIP perks – If you’re a high roller, your best bet is to go for a casino that actively rewards players like you (e.g. JackpotCity Casino, Playamo).
- RTP scores – You shouldn’t be deterred by lower RTP scores for progressive jackpot slots since, as we mentioned earlier, that doesn’t translate into lower profitability.
- Security, licensing and trust factor – Always play at jackpot casinos licensed by known regulatory bodies, such as the UK Gambling Commission or the Malta Gaming Authority.
- Payment methods and limits – A good jackpot casino should offer at least 2-5 trusted payment methods (credit/debit cards, e-wallets like MuchBetter, Mifinity, Trustly, etc).
