Progressive jackpot slots look just like any other slot machine with a variety of reels, multiple paylines, bonus games and so on. The crucial difference between progressive machines and all the others is found in the jackpot. Progressive slots are home to the biggest jackpots in all of online gambling.

If you daydream about winning millions of dollars, you can give it an honest shot by visiting a progressive jackpot casino site. Your odds of winning may not be the best, but people can and do win major jackpots. Hit the right combination of symbols and you could be the next internet millionaire.
Each of the casino sites on this page has a few progressive slot games with jackpots that routinely reach six or even seven figures. Even more important is the fact that these sites actually pay when people catch large wins. Over all the years each of these casinos has been in business, never once have any of them failed to pay a winner his due.
Safety is always an important consideration, but it takes even greater precedence when we’re talking about million dollar jackpots. After all, it’s not too much trouble to pay people who win a few dollars here and there. The real test comes when it’s time to pay the winner of a seven figure payout. I recommend the above sites because they have all been put to the test and passed with flying colors.
There’s another thing to consider with progressive jackpot sites, and that is the way in which large payouts are handled. If you read through the terms and conditions of any casino site (especially those that serve the US market), you may come across something called the “maximum weekly withdrawal.” It is not uncommon for sites to have a rule in which they only pay up to $5,000 per week.
A maximum weekly cashout is fine for average casino wins, but it simply doesn’t work for six and seven figure payouts. If your casino does have a maximum payout rule, make sure it has an exception for progressive wins. Any self-respecting casino website will work hard to make sure it pays the biggest winners quickly.
How Progressive Jackpot Slots Work
Progressive jackpots are named as such because they grow progressively larger over time. As people play and wager at that machine, the jackpot grows a little bigger every day. Eventually one lucky player triggers the jackpot and wins a couple million dollars. The jackpot resets at that point and starts growing once again until the next lucky player comes along.
The method by which progressive jackpot slots grow so large is by taking a percentage of every wager and adding it straight to the jackpot. As people enter coins and spin the reels, the jackpot grows larger and larger until someone triggers the payout.
Jackpots are often linked across multiple slot machines and even across multiple gaming sites. The jackpot can be linked across slot machines on the casino gaming floor or across the same machine hosted at various casino sites that are powered by the same software company. For example, a bunch of Microgaming casinos may all have a few machines that appear at dozens of casinos.
When you have multiple machines all contributing to a central jackpot, the prize pool builds quickly. These jackpots are able to grow to impressive levels until one person is lucky enough to hit the winning combination.
Know the Payout Rules
All progressive slots jackpots have unique rules for how and when the progressive jackpot is triggered. Make sure to check the pay table every time you try a new machine so you have a full understanding of what it takes to hit the jackpot.
For example, most progressive slots require you to wager a certain minimum amount of money or activate a certain number of paylines. Some machines require a minimum wager as high as $1 to $3 per spin. Make note of this and only play if you’re comfortable risking that much money.
Spinning a dollar or more at a time can get expensive in a hurry if you’re working with a limited bankroll. One thing I like to do is alternate my spins between smaller and larger amounts of money. This way I can stay in the action longer and still try to hit the jackpot every few spins.
You should also note that progressive jackpot slots tend to have a lower payback percentage than traditional machines. With a portion of each wager going straight to the jackpot, you’re not going to see a slightly lower payout frequency due to the money being taken out of the machine and going to the jackpot. This is offset by the fact that you’re given a chance to win a life-changing amount of money.
Biggest Online Slots Jackpots
The biggest real money jackpots in online gambling have always come from progressive slot machines. Other games may boast significant top prizes, but nothing can compare to the jackpots you get when hundreds of slots across the internet are linked together to create ever-growing jackpots.
Some specific slot games are known for having particularly large progressive jackpots. These are the machines to play if you want to aim for the stars and win one of those prizes that can significantly alter the course of your life. Read on for a quick overview of a couple of the biggest jackpot slots and see where you can play them today.
Monty Python’s Spamalot
Monty Python’s Spamalot Slot takes you on a quest with the knights in search of the Holy Jackpot. Guide your knights through four bonus games to have a shot at winning more than a million pounds/euros. The ultimate bonus round has you climb a hill with six levels. At each level, you need to avoid disaster by choosing the right symbol. At the final level, you choose between two items. Get it right and you’ll leave with the progressive jackpot.
At the time of this writing, the progressive jackpot was sitting at £1.73 million.
Shopping Spree
Shopping Spree is home to one of the biggest slots jackpots online. The jackpot here regularly exceeds several million dollars. At the time of this writing, the jackpot was sitting at about $5.5 million and growing larger by the minute. Hit the jackpot in this one and you’ll have all the money you need to pay off the mortgage and still have plenty left to go shopping in style any time you want.
Shopping Spree also has a secondary jackpot that will give you an actual shopping spree. If you hit five diamond rings, they’ll fly you to New York City to go on a $100,000 shopping spree anywhere you want. You can also just take the cash if you’d rather do it that way.
This slot accepts coin denominations of $0.25 only and has 9 possible paylines. You can wager up to 5 coins per payline and must place a total wager of 45 coins to activate the jackpot.
Jackpot Giant
Jackpot last seen at: £7,278,268
- RTP: 94.22%
- Available at: Omni Casino, and Ladbrokes Casino
- Minimum Bet: 0.01
- Maximum Bet: 4.00
- Paylines: 50
- Reels: 5
Jackpot Giant lives up to its name as a giant among progressive jackpot slots. No other game on the internet today has a bigger jackpot than this one. At the time this post was published, the jackpot had topped £7.2 million and was growing by the second. This is a very popular slot and the jackpot is very difficult to win – hence its ability to grow to such heights.
The progressive jackpot can only be won when playing the maximum possible bet (max coins per payline, all paylines active). When you place a qualifying jackpot bet, the jackpot is paid if you hit five wild symbols in a single payline.
One of the nice things about this slot is you only contribute to the jackpot when playing the maximum bet which qualifies for a progressive jackpot payout. If you place smaller bets, you are not funding someone else’s jackpot. The jackpot in this game only grows when people place full max bets.

Rise of the Pharaohs
Jackpot last seen at: £561,501
- RTP: 95.02%
- Available at: 888 Casino
- Minimum Bet: 0.15
- Maximum Bet: 150
- Paylines: 15
- Reels: 5
Rise of the Pharaohs has a surprisingly large jackpot considering how difficult the game is to find online. 888 Casino is the only major casino site we know of with this game, yet it boasts a jackpot in excess of £500,000.
The ancient Egyptian them is a bit cliché, but that is a small price to pay for a game that has a massive jackpot and presumably not as many people competing with you to win that jackpot. Sticky wilds, free spins and a bonus game that awards multipliers all serve to make things interesting as you strive to hit the mega jackpot.
Winning the progressive jackpot is completely random and can happen at any time. There is no special set of symbols you need to hit or any kind of bonus game that you must defeat to hit the jackpot. However, the odds of hitting the jackpot do increase based on the size of your bet and the number of selected paylines.

God of Storms
Jackpot last seen at: €483,270
- RTP: 96.14%
- Available at: Ladbrokes
- Minimum Bet: 0.01
- Maximum Bet: 250.00
- Paylines: 25
- Reels: 5
God of Storms is a fast-moving slot with multiple types of wild symbols, respin features and multipliers that can go as high as 5x. The game is also flexible with up to 25 paylines and the ability to bet as little as 0.01 at the low end to as much as 250 per spin at the high end. Whatever your bankroll, God of Storms can be configured to work for you.
The God of Storms progressive jackpot is shared with Age of Gods and the Marvle Jackpot, which means the amount of money that can be won grows quickly each day. A total of 0.99% of every bet placed at God of Storms contributes to the jackpot and there are no special conditions to qualify for the jackpot.
You can activate the jackpot game at any time with any number of coins. When the jackpot game is triggered, you’ll be taken to a screen showing 20 coins. Each of these coins hides one of the four jackpot symbols. Your job now is to select coins to flip them over and reveal the jackpot symbol hidden under that coin. Once three matching symbols have been revealed, you win the corresponding jackpot.

Mega Moolah
Jackpot last seen at: €1,000,143
- RTP: 88.12%
- Available at: PlayOJO, Betsson and ComeOn
- Minimum Bet: 0.01
- Maximum Bet:
- Paylines: 25
- Reels: 5
Mega Moolah is not my favourite progressive jackpot slot due to having a terrible RTP percentage of just 88.12 in an age where most other online slots have RTP numbers exceeding 95% pretty much across the board. Even so, the size of this jackpot is undeniable. Mega Moolah has been around for years and the jackpot has never failed to impress.
An African safari theme greets all comers with lion symbols serving as wilds and monkeys serving as scatters. If three or more monkey symbols appear anywhere on the reels, Megah Moolah enters free spins mode with 15 free spins and all winnings tripled. It is during free spins mode that you can win any one of the four progressive jackpots, including the biggest of all which is often worth seven figures or more.

Beach Life
Jackpot last seen at: €898,163
- RTP: 93.25%
- Available at:
- Minimum Bet: 0.50
- Maximum Bet: 10.00
- Paylines: 20
- Reels: 5
Beach Life is an aptly-named game that will indeed have you relaxing on the beach should you trigger the biggest jackpot they have on offer. This jackpot often approaches seven figures as one of the biggest progressive jackpot games you’ll find anywhere.
It’s a good thing the jackpot is so big, because this game does not have a whole lot going for it other than that. The graphics are quite dated by 2017 standards, the return-to-player percentage is not all that great and the minimum bet is a bit on the high side at 0.50.
The jackpot begins with 100,000 coins as the starting point and then grows from there as people around the world play Beach Life online. To win the jackpot, you need to play the max bet and then land five wild symbols (the sun) on the 20th payline. Beach life also includes a bonus feature which takes you to a screen containing twelve chests. You can then open three of those chests to receive the prize within. This feature is activated by landing three chest symbols on any active payline.

Hall of Gods
Jackpot last seen at: €3,896,410
- RTP: 95.5%
- Available at PlayOJO
- Minimum Bet: 0.01
- Maximum Bet: 50.00
- Paylines: 20
- Reels: 5
Hall of Gods is a sleek offering from NetEnt themed after seafaring Vikings searching for treasure as they cross rough seas. This game provides a combination of a large jackpot with crisp graphics and fast-moving games that sometimes seems rare for progressive slots. Low minimum bets and forced minimum to activate the jackpot ensure the game remains accessible to players of all bankrolls.
A pair of ravens set against a full moon serve as the scatter symbols while a hissing serpent serves as the wild and the hammer activates the bonus game. Three hammer symbols will take you to the bonus game where you use a hammer to break open shields and reveal instant payout prizes.
The progressive jackpot is won during the hammer bonus round. If you reveal three matching jackpot symbols, you win the correlating jackpot. The three possible jackpots are the mini jackpot, midi jackpot and mega (progressive) jackpot. You can win the progressive jackpot with any bet size, but larger bets do increase your chances.

Mega Fortune
Jackpot last seen at: €1,351,195 (often goes much higher)
- RTP: 96.6%
- Available at: PlayOJO and Unibet
- Minimum Bet: 0.25
- Maximum Bet: 50.00
- Paylines: 25
- Reels: 5
NetEnt’s Mega Fortune slot is home to some of the biggest potential jackpots on average. In fact, the current jackpot of €1.35 million is actually lower than average for this game. The Mega Fortune progressive jackpot often tops €3 million and has paid out for more than €3 million multiple times in the recent past, including this year.
The Mega Fortune jackpot topped €7 million as recently as this past December, but even that is not the biggest it has ever gone. In 2013, a gambler from Finland hit the top jackpot at Mega Fortune for a record-setting payout of €17.8 million.
Mega Fortune boasts a fitting luxury theme with slots symbols depicting fancy rings, exotic cars, glasses of champagne, wads of cash and private yachts. The bonus wheel symbols unlock the bonus game, and that is where the progressive jackpot awaits.
In the bonus game, you stop spinning wheels and win either a coin payout, rapid jackpot, major jackpot or the mega fortune jackpot. The bonus round can result in serious coin wins alone, but the ultimate objective here is to win the mega jackpot.

Mega Fortune Dreams
Jackpot last seen at: €2,189,241
- RTP: 96.4%
- Available at: ComeOn and Unibet
- Minimum Bet: 0.01
- Maximum Bet: 80
- Paylines: 20
- Reels: 5
NetEnt struck gold with Mega Fortune dreams as the original would eventually become one of the most popular progressive jackpot slots of all. They followed up with Mega Fortune Dreams as a sequel to the original.
Mega Fortune Dreams took the winning recipe of the original and made everything a little bigger with more ways to win, bigger max coin payouts, a new progressive jackpot, higher betting limits and improved graphics and music.
One thing that stands out right off the bat is much-improved music. I get that we’re all here for the jackpots, but the original’s elevator music was fairly grating. This one has a more relaxed soundtrack that sets a better mood for smooth luxury.
Once again, bonus wheel symbols activate the bonus game. The bonus game in Mega Fortune Dreams brings you to a multi-layer spinning wheel which you stop the outer ring first and then move your way in to the center. Starting from the outer layer, you stop the spinning wheel to win straight-up coin payouts and then move inwards as each layer promises bigger rewards including the rapid jackpot, major jackpot, and ultimately the mega jackpot on the inner-most layer.

Arabian Nights
Jackpot last seen at: €431,973
- RTP: 95.6%
- Available at: PlayOJO and ComeOn
- Minimum Bet: 0.50
- Maximum Bet: 5.00
- Paylines: 10
- Reels: 5
Arabian Nights is another old NetEnt title that has been paying big jackpots to lucky gamblers since 2005. The Arabian Nights theme provides a nice change of pace from the usual themes we usually see from slots providers, but the graphics on this game are certainly starting to look a bit dated. However, this game’s progressive jackpot remains as strong as ever with large payouts always just a spin away.
Scatter symbols provide free spins with a 3x multiplier while any winnings earned with the wild prince symbol are doubled. If you get five princes in a row while playing the max bet, the progressive jackpot is yours. Otherwise, five princes pays a straight jackpot of 10,000 coins.
This is a solid overall game, but players should be aware that the minimum bet to qualify for the progressive jackpot is a hefty 5.00. You can still play the game for less than that, but jackpot hunters will want to go in with a big bankroll or look to a different game.

King Cashalot
Jackpot last seen at: €218,309
- RTP: 90.45%
- Available at: ComeOn and Betsson
- Minimum Bet:
- Maximum Bet:
- Paylines: 9
- Reels: 5
Simple graphics, catchy name and a big jackpot are the hallmarks of this progressive jackpot slot machine. The odds are you’ll either love or strongly dislike this game. It has an old-school style that will either remind you of the good old days or make you think this game is so outdated that it should be retired.
In either case, the jackpot is always considerable and the winning conditions are simple: bet the max amount and then land five king symbols on the 9th payline to win the entire progressive jackpot. The jackpot in the past has reached as high as £1.5 million before being won.
In addition to the progressive jackpot, King Cashalot offers as high as 15,000 coins for five king symbols on any payline and a bonus game. Three dragon scatter symbols on reels 2, 3 or 4 trigger the bonus game in which you open chests to reveal prizes. Prizes shown in the bonus game are multiplied by the number of paylines activated and coins bet per payline.
