Types of Jackpot Slots

You will be happy to know there are plenty of different kinds of jackpot slots, providing a lot of game variety from which to choose. What’s more, new slot sites are always coming out with their own twist on the classic jackpot game, so you’ll never run out of chances to land the big one. 

Before diving into the most popular jackpot slot games, our experts here at Gambling.com have developed this handy cheat sheet to help get you started. Aside from regular jackpot slots, you’ll most likely find the following popular game types at our recommended online casinos:

Top Jackpot Slots at UK Casinos

Before getting to the best jackpot slot sites picked by our industry experts, it is worth starting with what jackpot slots you can expect to find at those online casinos. Our review team selects slots based on their overall quality covering gameplay, graphics, audio, features, payouts, and bonuses. Below are the jackpot slot games that provide the best combination of these factors:

Arguably the king of all jackpot slots, Mega Moolah is the most famous online slot when factoring prizes. That’s because it is also a full progressive slot with a base jackpot of £1 million. This classic also has a jackpot of 75,000 coins in the base game and 225,000 in Free Spins. Since launching in 2006, Mega Moolah has remained one of the premier jackpot slots UK customers can play. 

The safari theme is bouncy and fun, and several updates over the years have kept it fresh. You play across a 5x3 configuration with 25 paylines, while the RTP is 88.12%. Mega Moolah is an ideal slot game if you want to try a progressive with a high-standard jackpot. 

Often described as the main rival to Mega Moolah, Net Entertainment’s Mega Fortune is a luxury-themed jackpot slot known for making regular millionaires. Its progressive jackpot pays out on average every 65 days. And, with an average jackpot slot payout of £3.1 million, there’s a lot to love. 

A balanced math model makes Mega Fortune a surprisingly consistent paying game. It has a medium variance and an above-average RTP of 96.6%. This was initially a 2008 release, so the gameplay is relatively basic on a standard grid of 5 reels and 25 paylines. Still, the free spins bonus is a fun attraction that keeps the gameplay moving along. 

If you like Mega Fortune but want a more modern experience, Mega Fortune Dreams is one of the best jackpot slots to choose. It offers a more complete game packed with 10x multipliers, free spins, a bonus round, and re-spins. Spin the reels across 5 reels, 3 rows, and 20 paylines, and you can win a base jackpot of up to 21,000x your stake. 

This game also taps into the Mega Fortune progressive jackpot network. That means significant prizes are routinely available. A 96.4% RTP (7.5% for the jackpots) and medium volatility provide a hit rate of 34.2%. 

Divine Fortune is another jackpot slot from NetEnt, offering a generous standard jackpot alongside a local progressive jackpot. It is ideal if you like the idea of a progressive slot but want a smaller pool contributing to the jackpot. A local progressive essentially means the jackpot is set on a casino-by-casino basis. 

In terms of gameplay, Divine Fortune whisks you back in time into the age of ancient Greece and mythical creatures like the Minotaur and Medusa. As you expect from NetEnt, the Divine Fortune jackpot slot looks impressive and comes loaded with features. When spinning the 5 reels across 20 paylines, you get respins, multiplying wilds, free spins, and a bonus game where you can potentially win one of two fixed jackpots or the progressive Mega Jackpot. 

For a good combination of regular jackpot and progressive, check out the classic NetEnt slot Hall of Gods. Released in 2011, this is one of the top jackpot slots with remarkable graphics and a slick Norse mythology theme. You get the normal NetEnt combination of cool visuals, standout features (trebling multipliers on free spins, expanding wilds, and a bonus picker), and a solid 95.7% RTP. 

Hall of Gods uses a normal 5-reel and 20-pay line set-up to give players the chance of winning a fixed jackpot of up to 4,314x your stake per spin. There is also a progressive jackpot starting at £500,000. Hall of Gods does not pay out as regularly as the likes of Mega Moolah or Mega Fortune, but the average jackpot of £5.3 million is higher. 

Another noteworthy progressive jackpot slot in the NetEnt stable is Arabian Nights, which takes its inspiration from the classic stories of the same name. A more basic slot design makes this a good entry for beginners playing their first jackpot slot game. The fact that you can start from 10p per spin also means Arabian Nights works for casual online jackpot slot players. 

The 5 reels allow you to bet on 10 paylines, a simple configuration that makes this an accessible game. Don’t worry, high rollers; there is a progressive jackpot that triggers a win every 147 days on average, with an average payout of around £1 million. 

If you like your online slots with back-to-basics gameplay but want to try a jackpot slot game, Major Millions is waiting. All the action of this slot from the team at Quickfire is fast-paced, and any win you build will come in the base game. Yes, forget about bonus rounds, free spins, or respins; this is a pure slot game. 

Across 5 reels and 3 rows, you can wager along 15 paylines and win various prizes across them. You will need the 15th pay line to hit a winning wild combo to claim the progressive jackpot on the Major Millions jackpot slot. As for the visuals, it follows the old-fashioned style of the game, using a cheeky military theme that looks good even if Major Millions is ageing. 

Best Jackpot Sites

Now you know the best jackpot slots, it is time to discover the best online casinos to play them on. Our gambling experts have explored the UK online casino industry to find the leading sites. Each casino we recommend is reputable, licensed to operate in the UK, has eye-catching bonuses, and offers a rich selection of jackpot slots.

Party Casino

Party Casino is a paradise for online slots fans. No matter what type of slot you like, you will find it in one of the largest collections of games available to UK players. That includes over 320 jackpot slots UK customers can access from top providers like NetEnt, Play n’ Go, Pragmatic Play, and more. You can choose between the most lucrative jackpot slots, unique mechanic games like Megaways, or smaller daily jackpots. While Party Casino does not have the biggest bonuses, the site typically makes its promotions accessible with generous wagering requirements. 

Monopoly Casino

As its name suggests, Monopoly Casino is the best place online to play Monopoly slots, with around a dozen variants available on the site. However, Monopoly Casino is also an excellent all-around online slot casino with over 570 games from leading providers like NetEnt, Scientific Games, and IGT. A superb UI makes Monopoly Casino a breeze to use on mobile and desktop. When you register, grab a solid free spins welcome package. 

Megaways Casino

Megaways Casino is operated by Gamesys Limited, the same provider behind Monopoly Casino. That means the layout, game selection, and bonuses are almost identical between the two sites. The core difference is a focus on Megaways game. Although, Megaways Casino also gets its slick dark theme that is nice to navigate. It also provides a solid selection of jackpot slots, and we especially like Daily Doubles. Additionally, check out the selection of Megaways jackpot games, as this casino boasts one of the most extensive portfolios around. 

LeoVegas

LeoVegas has a relatively modest number of jackpot slots, especially considering the total number of online slots on the site. Even so, this is an expertly curated list of jackpot games. You get to choose between progressives, WowPots, Megaways, and several other types of jackpots. Flexibility seems to be the key to the whole LeoVegas experience, with a suitable selection of payment methods and a generous double-hitter welcome package. 

888casino

888casino boasts more than a thousand slot games and over 250 jackpot slots UK players can enjoy. These come from leading providers like NetEnt, Playtech, and Big Time Gaming. However, what sets 888casino apart is its exclusive games. There are dozens of slots, including jackpots, you cannot play anywhere else. Add a lucrative welcome bonus and an outstanding overall online casino, and it is easy to see why 888casino is one of the biggest global betting brands. 

777 Casino

777 Casino is something of a little sibling to its parent company, 888 Group. While not as complete as 888Casino, 777 provides a more bespoke experience to slot fans. Jackpot slot games from providers like NetEnt, Playtech, and the in-house 888 Gaming studio give customers plenty of choices. For UK players joining 777 Casino, the site also offers one of the best welcome bonuses currently available. 

Virgin Games

As another online casino from the Gamesys stable, Virgin Games UK is in the same mould as Monopoly Casino and Megaways Casino. Yes, that means another site that puts quality firmly over quantity. A solid selection of jackpot slots allows you to pick the type of game you want to play, such as smaller daily jackpots or major progressives. While not as good-looking as Monopoly or Megaways casinos, Virgin Games is just as easy to use on both desktop and mobile. 

Rainbow Riches

Yes, another Gamesys online casino, this time a site that focuses on the all-time classic slot Rainbow Riches. Such is the popularity of this game that numerous variants have launched over the years, some of them have been jackpot slots. While Rainbow Riches is light on other casino games, its online slots portfolio provides games from giants like NetEnt, Barcrest, and others. 

PokerStars Casino

Of course, PokerStars is best known as one of the biggest online poker networks. Although, the company also has an online casino that provides access to over 1,000 slots from NetEnt, Playtech, Quickspin, and more. There are a few hundred jackpot slot games covering all types of jackpots, from daily prises to multi-million progressive games. New customers can grab a no deposit free spins offer to start spinning the reels without hitting their bankroll. 

Magical Vegas Casino

Magical Vegas casino greets you with one of the best welcome bonuses around, giving you the chance to boost your bankroll when you register. Once you have an account, there is a broad selection of excellent jackpot slot games to play. We especially like the collection of Daily Drop slots that give solid prizes for quickplay each day. Of course, you also get plenty of progressives from providers such as NetEnt, IGT, and Play n’ Go. 

Progressive Jackpots

We have discussed progressive and regular jackpot slots throughout this page, often interchangeably. However, the two are slightly different. This may be confusing, so now is a suitable time to explain the differences and similarities between the two:

A golden rule to remember is that a progressive is a jackpot slot, but not all jackpot slots are progressive. So, the obvious question is, which should you choose? 

There are good reasons to play both standard jackpot slots and progressive jackpot slot games. It depends on what type of player you are. If you’d like to play over longer sessions and retain your bankroll for as long as possible, we’d recommend a standard jackpot. Payout rates are better, but obviously, you will have a smaller potential jackpot limit. 

On the contrary, a progressive jackpot slot is the best option if you are a high roller or the kind of slot player who likes to take risks in pursuit of the “big hit” win. These games reduce your chances of winning compared to classic games, but when you do win, you can often land a big prize. If you win the main progressive jackpot, you could see millions in prize money. 

However, it is worth noting many progressive jackpot slots, such as the ones we list on this page, also include a fixed jackpot alongside the progressive. 

Mobile Jackpot Slots UK

Your mobile device is your ticket to carrying an online casino in your pocket. You can play wherever and whenever you want, which is why mobile gambling is becoming the most usual form of gambling in the UK. 

Game providers understand this and build their slots on HTML5 technology. Without getting too technical, this means that games can run on both a desktop site and a mobile browser. Even older progressive jackpot slot games like Mega Moolah (launched in 2006) have been updated to accommodate gamblers on the go.

Yet, did you know you can also spin the reels of jackpot slots on dedicated casino apps? These applications offer increased usability, greater connectivity, and special alerts, meaning you can keep up to date on all the latest releases. When we review jackpot slot sites, we look for casino operators that provide a dedicated mobile app. 

Biggest Jackpot Slot Payouts

One of the best things about jackpot slots is that they do, in fact, payout. These massive jackpot prizes, such as the multi-millions of pounds you can win on progressive jackpots, are no false promises. While astronomical wins are rare, you may be surprised how often someone wins mind-blowing sums of money. Online casino history is filled with mega winners, and below are some of the biggest jackpot payouts over the last five years.

Top Jackpot Slots Game Developers

One of the best aspects of joining one of the jackpot slots sites we recommend is the choice of games. We select online casinos that provide a broad selection of jackpot slots from the world’s leading iGaming software providers. There are loads of notable providers, some that we have already discussed on this page. 

Below we will look into those developers more closely and introduce you to other major online slot creators:
