Best progressive jackpots and slot games for 2024

Slots are one of the biggest draws for online casinos. The average online casino will have hundreds of traditional slots to play.

Increasing in popularity are the jackpot slots — slot games where the jackpot grows as people play. Jackpot slots don’t pay out as often, but when they do, the winnings can be huge.

Besides the potential to win big, progressive jackpot slots are popular because players feel like they’re all playing together. Every time someone pays in, everyone can see the jackpot grow. It’s an added layer of excitement and a bit of community that online casinos often lack.

Not every UK online casino offers them, so finding the best jackpot slot requires a bit of research. That’s where we come in.

How we picked online casino venues to play jackpot slots

With so many online slot sites available, it can be difficult to choose where to play. We’ve made our list of top online casinos for jackpot slots by looking at the following key features. Each one is important to the player experience and we explain why below: 

• Security and licence – Having the proper licenses is essential for an online casino, that’s how players know it is safe to play at and that they have recourse if anything goes wrong. SSL 128-bit encryption is standard at all the best online casinos.
• Selection of jackpot slots – Jackpot slots aren’t as common as regular slots. The best online casinos have plenty of jackpot slot options for players.
• Promotions for jackpot slots – Who says no to free money or free spins? Promotions on jackpot slots help players get off to a good start and rarely go unused. 
• Deposit and withdrawal methods – The top online casinos offer a wide variety of deposit and withdrawal methods. These should include traditional methods such as debit cards and bank transfers, as well as digital methods, such as e-wallets and payment apps.
• Customer support – Being able to communicate with an efficient and effective customer support team is very important. We look for online casinos that have multiple ways to contact their customer support team.

Review of top casinos for jackpot slots

1. talkSPORT BET

talkSPORT BET is a new online casino that has lots to offer. They have a large game library, including a number of progressive jackpot slots. New customers can qualify for £30 in casino bonuses, plus 25 free spins on top!

They accept bank cards and bank transfers but do not have many digital payment options.

2. Duelz

Duelz has one of the leading libraries of video slots. They offer several jackpot slots, including multiple Mega Moolah variations. Their site is fully optimised for mobile so there is no need to download an app.

Duelz accepts all the top payment methods. Their withdrawal times do vary dramatically, however, from immediately to six days. Keep this in mind if you need to access your funds right away.

3. Mr Vegas

The Mr Vegas logo gives you a good idea of the blend of fun and class this online casino has. They offer many of the best progressive jackpot slots as well as a wide range of other slots, table games, keno and bingo.

Mr Vegas has a live chat feature that is available 24/7 and an email for customer support; however, they do not offer telephone support. 

4. Luckster

It’s easy to see why Luckster is one of the top-rated online casinos. Their welcome bonus includes a deposit match of up to £200 and 100 free spins. They have games from all the top providers, and they feature the leading progressive jackpot slots. 

Luckster does have a lower withdrawal limit than some of their competitors, so high rollers might not be interested. 

5. MrQ

MrQ is a smaller online casino that still has a lot to offer. They accept debit cards, PayPal and Pay by Phone, and users report fast deposit and withdrawal times. With a minimum deposit of only £10, it is easy to get started without making a huge commitment. 

The welcome bonus at MrQ is a bit disappointing as it only offers 75 free spins to use on Big Bass Splash.

2. Verify your identity and make your first deposit with an approved payment method.

What are jackpot slots?

Jackpot slots are slot machine games that have a jackpot alongside the regular wins. With progressive jackpot slots, that jackpot grows as people play. Jackpot slots are popular among players who love to chase the big win and don’t mind taking big risks either. 

What types of jackpot slots can you play at online casinos?

There are several different types of jackpot slots that you can play at UK online casinos. Each one has their own pros and cons.

Fixed jackpot slots

Fixed jackpot slots have a set jackpot amount that doesn’t change. These are also known as cash pot jackpots. They generally pay out more frequently than progressive jackpots do. 

Progressive jackpot slots

Progressive jackpot slots grow as people play. The more players pay in, the higher the jackpot goes. Progressive jackpots are where you see the biggest wins in the industry.

Must drop jackpot slots

A must drop jackpot has to pay out at a certain time every day or when it hits a certain amount. These jackpots are usually smaller because they are more predictable and pay out more regularly. 

Local jackpot slots

Local jackpot slots are progressive jackpot slots that are based in a single online casino. Only players playing the slot at that casino contribute to the growing jackpot. While this usually means that they are smaller since fewer players are paying in, so it also means that the odds of winning are better.

Network progressive jackpot slots

Network progressive jackpot slots are also known as pooled jackpot slots. The jackpot is created by pooling all the money paid in by every player playing across a network of online casinos. These are the biggest jackpots of all.

What’s the expected return-to-player (RTP) percentage for jackpot slots?

The return-to-player (RTP) percentage is the average amount that is returned to players as winnings. For the best jackpot slots, the RTP is between 93%-96%. The more you play the same online slot game, the more likely it is that you’ll reach the average RTP.

What are the best jackpot slots at UK online casinos?

Players looking for the best jackpot slots at online casinos in the UK have plenty to choose from. Here are some of our favourites from leading game providers:

• Mega Moolah – RTP 94% (Microgaming) – Mega Moolah is known as the ‘Millionaire Maker’ because of how regularly it pays out big money wins. This video slot has a safari theme featuring cute animal symbols. With four different jackpots, players have more chances to win. If you’re looking for the best jackpot slot, this might be it! 
• Hall of Gods – RTP 95.5% (NetEnt) – Hall of Gods is a Norse mythology themed slot with 20 paylines. It has a great RTP coupled with a scatter and free spins feature that lets players enjoy the game for longer. The average jackpot is over £4.5m!
• Jackpot Giant – RTP 94.22% (Playtech) – Spin your way into a fantasy land with Jackpot Giant. The highest jackpot is over £4m and players need to place the max bet of £4 to qualify. There are 50 paylines in this 5-reel slot.
• Joker Millions – RTP 94.3% (Yggdrasil) – Yggdrasil are big players in the world of slots but Joker Millions was their first progressive jackpot slot. It was only launched in spring 2023, so we still don’t know how often it will pay out. It has a classic fruit machine theme. The jackpot starts at £100,000 but can reach £3m.
• Wolf Gold Power Jackpot – RTP 96% (Pragmatic Play) – Wolf Gold Power Jackpot features Native American Southwest symbols on its five reels and 25 paylines. It offers four jackpots. One unique feature is that 50% of the major jackpot is shared out to the contributing players when it is hit, so even if you don’t win big you can still win!

How often do the best jackpot slots pay out?

Since slot machine games use random number generators to remain totally fair, it’s impossible to know exactly when a jackpot slot will pay out. The best jackpot slots do pay out fairly regularly, however. 

Sometimes jackpot slot pay outs are measured in time and sometimes in the number of spins. Major Millions, for example, hits the jackpot roughly once every six weeks while Jackpot King is thought to hit the jackpot once every 600 million spins. 

What are the odds of winning a jackpot from online slots?

The odds of winning a jackpot slot are lower than the odds of winning a traditional online slot. Since many jackpot slots are linked, meaning a lot of people are all competing for the same jackpot, the odds of winning the big money prize are even worse.

How much can I win on a jackpot slot?

The amount that you can win on a jackpot slot depends on which jackpot slot you’re playing. The biggest payouts don’t happen very often, but when they do, the amount of money you can win is life changing. The highest ever jackpot slot win in the UK was over £13m!

You’re more likely to win a smaller — though still impressive — amount. The amount that you can win on a jackpot slot depends on how much you have wagered. Jackpot slots pay out in multiples of the wager.

Can you play jackpot slots on your mobile device?

In general, yes, you can play jackpot slots on your mobile device. The top online casinos all either have a mobile app or a website optimised for mobile devices. Some online casinos don’t have all of their games on their mobile site, so make sure to verify that your favourite jackpot slot is available before you sign up.

What payment methods are available for jackpot slots?

The payment methods for jackpot slots depend on the deposit methods that the online casino accepts. The most common payment methods are debit cards, e-wallets and payment apps. The best payment apps, in terms of security and reliability are PayPal, Skrill and Neteller. 

What’s the lowest and the highest stake you can place on jackpot slots?

The lowest and highest stake that you can place on jackpot slots depends on the game that you’re playing. On most slots, two factors determine the stake: the coin value and the paylines. 

The coin value is the value the player assigns to the ‘coin’ being fed into the slot machine. This is typically between £0.01-£0.05 but can be raised to as much as £20. The number of paylines is often fixed by the casino but in some cases players can choose. The number of paylines can range from 1-40.

You can work out the stake amount by multiplying the two numbers. Say, for example, you set your coin value at £0.05 and there are 20 paylines. Your stake would be £1.00 because 0.05 x 20 = 1. 

The majority of jackpot slots will have a ‘Bet the Max’ option, so you don’t have to calculate it yourself.

What other games are popular at online casinos in the UK besides jackpot slots?

While jackpot slots might be one of the most popular games with those who want to win big, they’re not the only way to play at online casinos. The classic slots also have plenty of fans, especially because there are so many to choose from.

Table games are also among the top casino games. The classic card games — poker, blackjack and baccarat — all have their devoted players, and so does roulette.

Our tips and strategies for playing jackpot slots 

1. Set a budget – and stick to it! It can be very easy to spend more money than you intended when you’re chasing that big jackpot win. As disappointing as it might be, sometimes you will need to pull out before it’s over.
2. Play the slots with the highest RTP: A high RTP doesn’t guarantee you a win, but it does mean a slot is more likely to pay out close to what you’ve wagered over time.
3. Bet the maximum: Since some slots have betting requirements to be in the running for the big jackpot win, it’s smart to bet the maximum amount of money to make sure you have a shot at winning.
4. Have fun with it: Playing online slots should be a fun activity. If you start feeling stressed out or get so focused on the prize that you aren’t actively enjoying yourself, then it’s time to take a break.
