Best Progressive Jackpots & Slots for August 2025

Progressive slots are like normal slot games but with one massive difference, there's a huge jackpot up for grabs. You can win millions on one spin of the reels and it's this giant jackpot potential that makes progressive slots such a hit with players at both land-based and online casinos.

All progressive jackpot slots work in a similar way to one another. Every time any player clicks ‘spin', a percentage of their stake goes into the jackpot pool. The progressive jackpot carries on growing, getting bigger and bigger, until one lucky player wins it.

How you actually win the jackpot can vary from game to game but most slots have a special Jackpot Bonus Game where your progressive jackpot win will be revealed.

Playing progressive slots is identical to playing normal, non-jackpot slots. All you have to do is select how many lines you want to bet on, what your bet will be and then spin the reels.

Jackpot Bonus Games also work like most other bonus games and you will usually have to spin a wheel or ‘click and pick' to see what you've won.

If you're looking to win big, then yes. Standard slots have the potential to payout tens of thousands of pounds in winnings but progressive jackpot slots regularly pay out over £5 million.

Progressive slots offer you the chance to win a life-changing amount of cash in a matter of seconds, whereas a standard slot only gives you the chance to win a maximum prize of up to 100,000x your bet.

The odds of winning on a progressive slot are pretty much the same as the odds of winning the lottery but the big difference is that you have way more chances to hit a progressive slot jackpot.

That's because of the amount of spins you can take during a gaming session. Unlike the lottery where you buy a ticket (or maybe 10 if you're really serious), in a progressive slot you can fit hundreds of spins into an hour and that means hundreds of unique opportunities to pocket a fortune.

Without a doubt, the most popular online progressive slot game is Mega Moolah. The slot is made by the Microgaming software company and offers the largest jackpot in the world.

Microgaming and NetEnt software have a whole host of different jackpot slots and they're all well-known for paying out record breaking amounts of cash. If you look at the list of the biggest jackpot payouts above, you'll notice that all of them are produced by either NetEnt or Microgaming.

The Mega Moolah progressive slot has four jackpots attached to it and the biggest one, the Mega jackpot, is the largest and has previously grown to over £13 million.

The Mega Fortune jackpot slot has 3 progressive jackpots. The largest one has previously climbed as high as €17.8 million.

The Arabian Nights progressive slot from NetEnt has also be known to payout more than €8 million.

It depends on the game. Some hit as frequently as weekly, while others could be less than once a year. Check our jackpot tracker at the top of the page to see how often the average hit is and whether a game is hot or cold.

There is no magic formula for winning a progressive slot jackpot, all you need is luck and determination.

Whenever you play any kind of slot game there is no guarantee of winning but with a progressive slot, when the win comes it could be really huge. Remember that the more spins you take, the more chances you'll have to scoop those millions for yourself!

Yes, but you won’t win any real money - the reward will likely be coins for further play. Still, free slots are a great way to try a game out before committing to it and betting your own hard-earned cash. Visit our free slots page to find the best games for you.
