Jackpots are Won Every Day in Online Casinos – This Guide Shows You Where and How

Jackpots divide opinion. Some people have the ‘glass half empty’ view that the part of the money you spi with that goes to making up big jackpot prize pools for the lucky few is wasted…

I have a different view.

Even if you do not win life-changing money during a session does not mean you do not get extra enjoyment from the fact that you gave yourself the shot.

Casino Jackpots GuideIf you are not familiar with what I mean by ‘life changing money’ then here are some facts about online casino jackpot payouts.

  • The largest single win was €17.3 million, won on the NetEnt Mega Fortune online slot by a Finnish player in 2011.

  • There are jackpots of over $1,000,000 on slots by PlayTech, MicroGaming, IGT, NetEnt and RealTime Gaming. Plus many more 6-figure ($100,000+) pools.

  • These are being won every month, with 5 and 6 figure payouts a weekly occurrence.

It is not only slots which have jackpots. You can find these in table games including blackjack, poker and roulette too. Scratch cards and bingo type games also have jackpot prizes.

This page gives you a complete overview. First of all below the different types of jackpots are covered (progressive, linked and so on). After that you will find out about which casino software has the best jackpot prizes.

Which Casinos Have the Best Jackpots?

Different Types of Slot Jackpot at Online Casinos

How do some jackpots get to be $10,000,000+ while others are ‘only’ $500,000?

This depends on two main things. First how often the jackpot is paid, and second how connected the jackpot pool is between different slots and casinos.

The Biggest Jackpots of all – The Big Linked Progressives:

All of the biggest jackpots have one thing in common. They can be won via many different online casinos. These prize pools are shared thanks to the way games are developed and licensed. Specialist software houses make the games and run the jackpots on behalf of the casinos. MicroGaming is perhaps the best known of these – along with their jackpot games Mega Moolah and Major Millions.

All of the casinos licensing MicroGaming software show the same jackpot amounts. Anyone playing at any of these casinos has a chance of winning the top prize, and every spin on these slots will contribute to the total prize pool.

This means the jackpot amount rises quickly, due to all the different players at different casinos contributing to this. Then the bigger prize amount starts to attract even more players, creating a feedback loop which quickly mushrooms into the giant sized jackpots that we see online today.

One more factor, when the prizes are won the big pool allows the ‘seed’ or starting point for the next one to be big too – which keeps a jackpot alive.

You will find information on the best linked progressives in the section on jackpots for different software types below. My tip here is that some of the bigger casino brands offer slots from several different software providers – giving you all the jackpots in one place.

Themed Jackpots – Shared Between Different Online Slots

A second common type of online slot jackpot is a pool shared between several games. These might also be shared between different casinos that host these games.

The best known of these for many players are the PlayTech-created Marvel Slots range. These are excellent games, which are based on the latest movies and often have entertaining break out video quality bonus games. What the 10+ slots in this range share is a jackpot. This pays at random (separately from the symbols on the reels) via a pick-em game, and often reaches a high 6 figures.

Other shared jackpots include the US friendly ‘Reel Series’ from RealTime Gaming. There are a lot of slots in their range including the entertaining Aztec Riches and Jackpot Piñatas. This is a multi-million dollar shared pool, which will pay at random from any one of the featured slots. There are 4 levels of jackpot, with the smaller ones paying quite often.

Finally in this category is the ‘Mega Jackpot’ from IGT. This is shared between several flagship slots like Cleopatra, Monopoly and Siberian Storm. If you scoop this pool on any of the games, you could be in for a $1,000,000+ payout.

The best place to head for online slots for is the Unibet casino. Not only do you get the security of a huge brand, you’ll find slots and jackpots from many of the biggest software houses there including MicroGaming, IGT, NetEnt and more. Unibet also look after their loyal players better than any other online casino. See the latest promos and check out the exceptional choice of games at for yourself now!
The place to head for online slots for US based players is This casino is part of the global Bodog family, and offer a huge range of slot games from 3 different software houses (RTG, Rival and BetSoft). These include huge jackpot games, mobile slots, 3D slots and even the famous progressive iSlots range. Bovada are a clear number one for slot promotions too. Check out for yourself now!

Jackpots Available at Single Casinos

Not all jackpots are shared, in fact some of my favorite big prize slots are only available at specific casinos. These outfits have to be the big brands which have the reach and marketing budget to generate plenty of action. Examples here include 888 Casino, which has the Millionaire Genie slot (and several more), which has a $1,000,000+ pool a lot of the time. Again this is triggered at random, making someone very happy indeed every few months!

Party Casino is another operator which has a big enough base to host its own jackpots. The highlight here is Mellon Madness, this has a jackpot in the 7-figures much of the time too.

Jackpots for Individual Online Slots

Individual Jackpot Slots – The Many Variations

While the big pools are covered above, this is really just the stand-out games in a very diverse world. There are plenty of individual slots with jackpots in the 6 and 7 figure range. Underneath this amount there are literally 100’s of games which could see you winning $5,000 or more from a single spin.

A popular theme is to have more than one jackpot total. A big one, and then one or more minor pools which will pay out more often. You will often find games where the top prize for lining up the right symbols is huge, though not progressive.

I recommend you start with the following articles, which will help you choose the best slots online including those with big payouts, fantastic bonus games and new / interesting features:

Which Casino Software Has the Best Jackpots

Once you find out that multiple casinos license games from a small amount of software houses, the question of where to find the best online slot jackpot becomes ‘which software has the best slot jackpots?’ instead.

Here are some general facts and figures, below this the individual software (and which casinos you will find these games at) is covered.

  • PlayTech have the most jackpot slots and the biggest selection of different jackpots. This software is used by many of the biggest gaming brands – allowing for millions of players to reach the same games.

  • Net Entertainment (Net Ent) is next in terms of the overall number of jackpots. The biggest ones are focused on their ‘Mega’ range of slots.

  • Some of the other big pools come from the big stand-alone casino brands 888 and Party. You’ll find as many jackpots at those casinos as some of the bigger shared software like MicroGaming.

  • For US Players, the only really huge jackpot comes from RealTime Gaming, this multi-million pool is available through 2 of their flagship slots.

Jackpots from Different Casino Software

PlayTech Progressive Jackpots

There are more jackpots at PlayTech Casinos than most of the others put together. The biggest prizes come from a slot which I personally never liked – Beach Life – this one regularly pays multi-million prizes, and has 4 of the top 5 payouts of from PlayTech, each at around the €5,000,000 mark.

Marvel slots are excellent, and share a jackpot prize (which is also shared with the Marvel Roulette game). There are 12 in the range at the moment - with a jackpot which is usually above half a million euros.

The Marvel range get so much of the spotlight when it comes to reviews and discussions of PlayTech jackpots, that you might miss the fact that there are plenty more games which have even bigger prizes. Here are some of the highlights:

  • Jackpot Giant: Popular Easter Island themed game with €5m+ pool

  • Beach Life: Dated video slot, though regularly has €2m+ prize pool

  • Spammalot: Monty Python themed game, Holy Grail jackpot often €1m+

  • Gold Rally / Gladiator / Funky Fruits / Sweet Party: 4 more games which separately have €1m+ jackpots

Once you get below the million+ level you will find an even longer list of games which have progressives seeded at €100,000+. Check out Cat in Vegas, Wall St Fever, Thai Temple of Frankie Dettories Magic 7 for some solid examples from this category.

There are also table game jackpots and even pools linked to novelty games. You might find the idea of playing darts online a little strange – though the €275,000 euro top prize is nothing to laugh at!

PlayTech make top quality games. For fans of jackpots, nobody else has this many big and mid-sized pools. I recommend the Unibet Casino for the full range of these slots (plus 100's of others from other software makers, with 660 titles in total). Check out the latest player promos list at now!

Net Entertainment Progressive Jackpots

NetEnt still hold the record for the single biggest jackpot win online. This was €17,800,000 and was won by a Finnish player in 2013 on the Mega Fortune slot. There were €8.5 million and €7.8 million wins during 2015 – as well as many ‘small’ (only by comparison) wins on top.

While Net Entertainment offer a lot of the mid-sized jackpots, their big ones are focused on the ‘Mega Fortune’ range of games. This used to be one slot, a simple enough video slot with symbols based on the trappings of wealth. Newer versions of this slot called Mega Fortune Dreams and Cosmic Fortune have been developed.

Player Caution: Some of the bigger casino brands keep their own pools for these slots, while others share the centralized giant pool. This can make a big difference (millions in some cases). Make sure that you are playing for the biggest pool!

Other Net Entertainment slots with big jackpots include the ‘Wonders’ series (Icy Wonders, Tiki Wonders and Geisler Wonders), Hall of Gods and Arabian Nights.

For NetEnt slots I recommend Unibet, this is a giant European brand which has the reach and player base to ensure the biggest prize pools. They also have jackpot games from MicroGaming, PlayTech, IGT and more. See for more.

NetEnt Mega Fortune Jackpot

RealTime Gaming Progressive Jackpots

RTG slots are the number one choice for US players by a long way when it comes to accessing big jackpots. These are solid games (rather than the complex / interactive style of the software houses covered above). What I like about RealTime Gaming slots is that the jackpots are paid completely at random. The symbols on the reels make no difference, you’ll have a normal spin, nothing happened and then *boom* a potential windfall of $1,000,000+ comes your way.

There are 5 main slots with big jackpots. You need to check your casino for two things before you play. First, check the number of coins (or minimum spin amount) needed to get a shot at the jackpot. Second, make sure that your casino offers the big shared prize pool – as some casinos have their own smaller pools using the same titles.

Here are the key slots to look for:

  • Aztec Millions: This south-American themed game has a huge $1.7 million prize at the time of writing.

  • Shopping Spree: There is now an updated version of this slot, which is responsible for both of the biggest ever payouts for this software.

  • Midlife Crisis: Another one which can pay $1m+, this is a humorous look at men getting older!

  • Jackpot Piñatas: This is another $1m+ game, this time based on Mexico / Spanish flavors.

  • Megosaur: The most recent prize (again, at the time of writing), has a multi 6-figure jackpot prize pool.

You will also find a lot of table game jackpots at RealTime Gaming Casinos (this software is well known for their solid and good quality table games).

US Players can find all of these slots (along with 100’s more from RTG, Rival Gaming and BetSoft) at the biggest US friendly online casino – Bovada. This casino is famed for their player promotions and solid service – check out for the latest offers now!

MicroGaming Progressive Jackpots

For a software type which has been so closely associated with big jackpots – there are relatively few games which offer multi-million prizes at MicroGaming casinos.

Best known of these is the Mega Moolah game. To say that this pays out huge prizes would be an understatement – the biggest so far was paid in pounds, all £13,000,000+ of them! In the same way that the Mega Fortune slots have grown in number, there are now a number of Mega Fortune games available. These include Mega Moolah Isis, Summertime and now 5-reel Drive. All of these games access the same prize pool. You can win the MicroGaming jackpots in a number of different currencies (Euros, Pounds or Dollars).

Other MicroGaming jackpot slots include:

  • Major Millions: Retro army officer theme, not the greatest slot ever built, though does have its fans and the $1m+ big wins help.

  • The Dark Knight: Amazing graphics and bonus games on this Batman movie tie-in game. Another with a $1m+ prize at times.

  • King Cashalot: Colorful though older video slot with a progressive which is often in the high 6-figure range.

MicroGaming also has table games with progressive jackpots, and plenty more slots with 5-figure prizes – either progressive pools or via regular play.

This software is highly rated, and their newest slots are must-play for anyone who is serious about this type of game. You’ll find the big prize MicroGaming slots at

IGT Jackpot Slots

The concept of the pooled jackpot was created by IGT, when the ‘Mega Riches’ the first live casino slot with a shared pool (between different Vegas casinos) was introduced. With IGT slots now available online, you can enjoy the TV / Music / Movie tie-ins at home – and also play specific games for a change of a multi-million prize.

IGT share their main jackpot between 4 different titles, and the different casinos which host their software helps the pool to grow large.

This is known as the ‘Mega Jackpot’, here are the slots currently in the range:

  • Cleopatra: This was the most popular and famous of the IGT slots for many years, and has recently been upgraded. It is a simple yet solid game by today’s standard, a 5 reel video slot with free spins bonus round, multipliers and wilds.

  • Monopoly: There are many different Monopoly slots (not all of them by IGT). This is the only one which can make you a real millionaire online though.

  • Cluedo: This video slot is based on the detective board game, there is a bonus round based on the game.

  • Siberian Storm: A modern and very slick slot with an unusually shaped reel format. I was a fan of this game before they introduced the jackpot version and now recommend it.


Party Casino Jackpots

The only other casino big enough to offer unique jackpots for its players is Party Casino, which is operated by the Bwin Party group.

Their setup is a shared jackpot system, with a single pool covering many slots including the entertaining Mellon Madness and Snow Business. This jackpot is regularly in the $2 million+ range. The other pool is called the ‘Gold Mega’, which is seeded at $500+ and can go over the million mark. There are several other games linked to this pool, including Dragon’s Hoard, The Sting and Hawaiian Madness.

Party has a trusted track record, and offer gaming options in poker, sports and at a very good casino. My only minor concern is that if you do win the big jackpot, you will need to take this out in stages.

Other Notable Jackpots by Software

This guide is already huge – so I decided to summarize the jackpots of other casino software types below instead of giving them all detailed sections. You’ll find some links to individual guides which cover the slots and jackpots of these casino software producers.

  1. BetSoft: Amazing 3D slots from this software house, which are available at US friendly online casinos. Jackpots are controlled by the individual casinos, though still get into 6-figures at the bigger operations. Look out for the Good Girl / Bad Girl game, Mr. Vegas and Greedy Goblins. Bovada have the biggest prize pools at the time of writing (US only)
  2. Cryptologic: (Now Amaya) A name from the past which still produces some solid slots which are licensed out to non-US casinos. The Millionaire’s Club is the standout game, this pays out $2m+ at a time on occasion. There are many 5 and 6 figure prize pools including Rags to Riches and Crazy Jackpots.
  3. Yggdrasil: Joker Millions is the slot to play from this inventive software maker. Their non-jackpot slots are worth a look – with ‘The Dark Joker Rises’ a personal favorite.
