Reviews of the 5 Best Progressive Jackpot Slots Online 2025
Before we go looking for the best online casinos to play progressive jackpot slots at, let’s take a better look at the games themselves. We reviewed the best slots with the progressive jackpot feature and we bring you a detailed review of each of the top games.
1. Mega Moolah – The Biggest Progressive Jackpot on the Internet
- RTP: 93.42%
- Paylines: 25
- Jackpot Type:
- Volatility: Low
- Max Payout: 1920x
- Provider: Microgaming
- Theme: Safari
- Minimum Bet: $0.25
First released in 2006 by Microgaming, Mega Moolah is the most iconic of all progressive jackpot slots. It is commonly found across all top online casinos for real money. We tried both the original game and several of its spinoffs that were launched in more recent years, and we were not disappointed.
As soon as you launch Mega Moolah, you will be sent on a virtual safari in the plains of Africa. The game’s soothing sounds and cartoonish visuals will allow you to put the stresses of the day behind you and enjoy the ride.
Mega Moolah is not just famous for its pleasant visuals, but also the amazing opportunities to win life-changing jackpots. With all of the biggest progressive jackpot wins over the years coming from Mega Moolah, this slot is an absolute must-try for any real jackpot hunter out there.
Pros
- The biggest progressive jackpot anywhere
- Enjoyable theme and basic gameplay
- Low volatility in base game
- Rewarding free spins feature
Cons
- Very low overall RTP
2. Mega Fortune – Luxurious Experience with Multi-Million Payouts
- RTP: 96.6%
- Paylines: 25
- Jackpot Type:
- Volatility: Low
- Max Payout: 2162x
- Provider: NetEnt
- Theme: Wealth
- Minimum Bet: $0.25
Another classic in the realm of progressive jackpot slots, NetEnt’s Mega Fortune was launched back in 2009. This game is all about wealth, with symbols representing limos, wads of cash, champagne glasses, and other items from the daily lives of high society.
We loaded up Mega Fortune and were instantly projected into a different world of luxury and splendor. Each spin of the reels is an enjoyable adventure, with wild symbols and free spins added into the mix to make the overall experience quite exciting.
The main feature of the Mega Fortune slot is the progressive jackpot wheel of fortune. If you are lucky enough to activate the jackpot game, you will get to play through four levels of the wheel, with the middle level hiding the multi-million progressive jackpot. If you aren’t quite lucky enough to win that, plenty of valuable consolation prizes are available. Among these are the Rapid and Major Jackpots, which are significantly smaller than the Mega, but still valuable.
Pros
- The crowning jewel of the NetEnt slot lobby
- Exciting theme and gameplay features
- Free spins and wild symbols
- Three jackpot levels
Cons
- Slightly outdated animations
3. Hall of Gods – Exciting Slot with Multiple Jackpot Opportunities
- RTP: 95.5%
- Paylines: 20
- Jackpot Type:
- Volatility: Mid
- Max Payout: 4314x
- Provider: NetEnt
- Theme: Norse
- Minimum Bet: $0.20
Another popular jackpot game from the NetEnt studios, Hall of Gods introduces the player to ancient Norse mythology. For all the history and mythology buffs out there, Hall of Gods is one of the most enjoyable online slot machines you could try, as it features symbols, music, and little details taken right out of the history books of the Nordic people.
Much like Mega Fortune, Hall of Gods features favorable RTP levels and three jackpots, with Mini and Midi playing the role of consolation prizes. The Mega jackpot can be won through the special jackpot game and is by far the game’s biggest and most lucrative prize.
Aside from the jackpots, Hall of Gods includes several exciting gameplay features, such as free spins and expanding wilds, which make every spin a real winning opportunity. Compared to a slot like Mega Moolah, an average spin of Hall of Gods is more exciting and offers slightly more risk and slightly better returns.
Pros
- A range of base game features
- Exciting game for history buffs
- Huge Mega jackpot opportunity
- Three jackpot levels
Cons
- Slightly higher bas game volatility
4. Arabian Nights – Enchanting Treasure Hunting Adventure
- RTP: 95.6%
- Paylines: 10
- Jackpot Type:
- Volatility: Mid-High
- Max Payout: 2000x
- Provider: NetEnt
- Theme: Arabia
- Minimum Bet: $0.05
Have you always longed to explore the mysteries of the ancient Arabian culture, rub the magic lamp, and take a ride on the flying carpet? Arabian Nights slot from NetEnt is a progressive jackpot slot that will take you into this world and provide infinite hours of entertainment with Aladdin and his enemies.
With 10 simple paylines and a chance to win 15 free spins, the game would be one of the top NetEnt slots even if not for the jackpot feature. Compared to a game like Guns N Roses, Arabian Nights has a lot more to offer in the base game, as the wins you will be playing for are very real.
The jackpot feature itself is triggered completely randomly and there are no smaller jackpots to speak of. The main Arabian Nights progressive jackpot, however, is one that’s well worth waiting for, as it offers a chance to change your entire life in a single spin of the reels.
Pros
- Epic adventure into the Arabian desert
- Big base game wins and free spins
- Low minimum bet option
- Enjoyable Oriental sounds
Cons
- No mini jackpots avaibale
5. Major Millions – Classic Slot with Huge Progressive Payouts
- RTP: 89%
- Paylines: 3
- Jackpot Type:
- Volatility: Mid
- Max Payout: 8000x
- Provider: Microgaming
- Theme: Classic
- Minimum Bet: $0.03
One of the few classic slot games to feature a progressive jackpot, Major Millions is a game that appeals the most to players who enjoy simple slots. This slot features a single payline with just three symbols. The symbols in the game are cherries, sevens, and bars, all taken from the early slot games that launched the entire industry.
Major Millions may not be the most exciting game to play, but it is a very consistent game that rewards patient players. We tested Major Millions at low stakes and had the opportunity to enjoy the base game and go for the progressive jackpot, although we were not fortunate enough to actually land it.
If simplicity is what you are looking for, Major Million is a much better option for you than a game like Arabian Nights. With very few gameplay features and straightforward mechanics, Major Millions is a slot even a complete novice will understand in full.
Pros
- Simple gameplay with a single payline
- Solid base game payline payouts
- Easy to understand paytable
Cons
- Lack of gameplay features
- Low overall RTP rate

Progressive Jackpot Providers
The best progressive jackpot slots come from a variety of software providers. These providers are big iGaming software studios, usually focused on the development of slot games. Some of the best progressive jackpot slots are created by providers like:
- Microgaming: One of the biggest software providers in iGaming and the company behind the fabled Mega Moolah slots, Microgaming is a legendary software studio known to most slot aficionados.
- NetEnt: Another major name in the realm of video slots, NetEnt stands behind popular progressive jackpot slots like Divine Fortune and Hall of Gods. On top of this, NetEnt provides one of the biggest slot portfolios in the world.
- Playtech: The developer of Jackpot Giant, Playtech is one of the most prominent companies that develop casino software. Aside from games, Playtech also develops software that keeps online casinos running across the board.

What Are Progressive Jackpot Slots?
Progressive jackpot slots are a category of video slots with a built-in jackpot feature. Each time player plays one of these games without winning the jackpot, its value goes up.
Unlike most slot games, progressive jackpot slots share their liquidity across many online casino platforms. This allows thousands of players to play the same game and fight for the same progressive jackpot, which can be worth millions of dollars.
The starting value of a progressive jackpot, called “seed value,” is fronted by the game’s developer after the jackpot lands. From there, the value grows each time the game is played, with a small percentage of every bet made going towards the progressive prize pool.
For example, the popular Mega Moolah progressive jackpot from Microgaming starts with a seed value of $1,000,000. Each time you place a bet on the slot, a small fraction of that bet goes into the jackpot prize pool, slightly increasing it. This affects the overall RTP of the game slightly, as the portion of the money that goes towards the jackpot is taken out of the game at the very start.
Why Play Progressive Jackpot Slots?
So now that you know how progressive jackpot slots work, you may be wondering why you should play them. For the most part, progressive jackpot slots are just like any other video slots, and they include all the features you would expect in a slot game. So, you might decide to play a progressive jackpot slot because you enjoy the theme, graphics, or gameplay features other than the jackpot.
However, most people play progressive jackpot slots with the hope of winning the top prize. Indeed, these jackpots can be worth millions of dollars, and these are the only slot games that allow you to win such a big prize. In fact, winning a million dollars while betting just one dollar or less is not possible in any other casino game. If you are looking for a chance to strike gold in an online casino, progressive jackpot slots are your best bet!

How Do Progressive Jackpot Slots Work?
We already briefly explained how progressive jackpot slots work, but let’s get a little more specific. When you load up a progressive jackpot slot, you will usually see the jackpot displayed on the screen quite clearly, as it is the main selling point of the game.
Whenever you play a game with a progressive jackpot, you should be aware of a few main things. One is the fact that you will be making a contribution towards the jackpot every time you spin the reels. Another is that these contributions will affect the overall RTP of the game and the amount of money you can expect to win back from the game.
Player Contributions
Every time you make a bet at progressive jackpot slots, a small fraction of your bet will go into the jackpot prize pool. For example, if you are betting $1 per spin, one or two cents will usually be taken out of the bet and added into the prize pool. The exact amount differs from one game to another, but as much as 5% of all your bets may be reserved for the jackpot.
If you want to avoid paying contributions towards the jackpot, your only choice is to play slots without progressive jackpots. If you choose to play a progressive jackpot slot, you will have to pay a contribution every time you spin the reels, without exception.
RTP & Volatility
The contributions you make towards the progressive jackpot affect the slot’s RTP and volatility. For example, imagine playing a progressive jackpot slot that displays an RTP of 96.5%. This is the overall RTP that includes the progressive jackpot, which will only be won by one of the thousands of players spinning the reels.
If the slot also takes a 5% progressive jackpot contribution, you can consider that an extra 5% off the overall RTP unless you happen to strike the jackpot. For everyone else, the game will effectively have an RTP of 91.5%.
All the extra money that’s being taken out of each bet goes into the jackpot, which is all won by a single player. This means the volatility of progressive jackpot slots is higher than any other game out there, which is worth keeping in mind the next time you play.
Types of Progressive Jackpot Slots
There are hundreds of jackpot slots out there, and they are certainly not all the same. In fact, there are several different types of progressive jackpot slots you can find in major online casinos. The games differ in jackpot value, the way the prizes are distributed, and more.
Here are a few key categories of online jackpot slots you can find:
Fairness of Progressive Jackpot Slots
A fair question that people often ask is whether online progressive jackpot slots are fair. Of course, the answer is yes, as all slot results are based entirely on the outputs of random number generators (RNG). These computer algorithms produce numbers as close to complete randomness as possible, are virtually unhackable, and are typically very reliable.
If you are concerned about progressive jackpots being “rigged,” you really shouldn’t be, as there hasn’t been a single incident reported of such a jackpot being disputed. For ultimate security, you can check out Bitcoin progressive jackpot slots, whose RNGs are based on blockchain technology and are provably fair.
Famous Wins on Progressive Jackpot Slots
Some of the biggest wins ever recorded in online casinos have come as a result of progressive jackpots. While various jackpot slots have paid out multi-million prizes over the years, Microgaming’s Mega Moolah slot is responsible for all of the biggest payouts over the years.
Here is a quick look at the top five online progressive jackpot slot wins in recorded history:
| Jackpot Slot | Total Payout | Year |

Strategies for Playing Progressive Slots
For the most part, video slots are games of pure chance. While there isn’t too much you can do to change the outcome once the reels are in motion, there are strategies you can use to improve your winning odds and maximize your bankroll efficiency.
Here are a few basic strategy tips you can use to improve your experience when playing progressive jackpot slots:
- Find the Best RTP Games: Playing slots with a higher RTP gives you a higher chance of success every time you play. In the long run, these games will perform better than games with a lower RTP.
- Look for Juicy Jackpots: Progressive jackpots grow over time. Find the ones that have grown substantially and go after them. If you happen to get lucky, you may as well win the biggest jackpot possible.
- Mind Your Bankroll: Your bankroll is the only tool you have when playing slots. Make sure to always play for stakes that are reasonable for your current bankroll, and don’t bet more than you can afford.
- Know When to Stop: Playing slots is all about knowing your limits. Learn when to walk away as a small winner and definitely don’t chase your losses. Set time limits on your play and don’t play beyond these limits.
Responsible Gambling
Being responsible when gambling is very important, and even more so for progressive jackpot players. Winning a jackpot is a once-in-a-lifetime event, so don’t expect you will win one anytime soon. Instead, approach the games with a responsible gambling mindset, set both financial and time limits, and be honest with yourself.
If you find that you are losing control of your gambling habits, use the tools at your disposal to change things around. The self-exclusion mechanisms allow you to exclude yourself from play for a limited time and take a break. If this isn’t enough, look for some help with a responsible gambling helpline and seek further steps on a path to healthier habits.
