What are Progressive Slots Online?
Progressive slots online are a popular type of casino game where the jackpot increases each time the game is played. These slots are interconnected across a network of machines, often spanning multiple casinos, both online and offline. Each time you make a bet, a portion of that wager contributes to the growing jackpot. This can lead to massive payouts, sometimes reaching millions of pounds, attracting many players eager for the chance to win a life-changing sum.
Progressive slots come in various themes and formats, including classic three-reel games and more complex video slots. The allure of potentially enormous jackpots, combined with the excitement of slot play, makes progressive slots online a staple in the gambling world.
How We Rate the Best Progressive Slots in the UK?
Even when it comes to jackpot slots, we wouldn’t just recommend anything and everything. We employ a thorough vetting process to ensure that you can enjoy a superb gaming experience and potentially even win big. Let’s go over the most crucial aspects we pay attention to.
Overall Popularity – Popularity is a significant indicator of a progressive slot’s appeal and reliability, plus, a large player base contributes to higher jackpot growth rates. To determine popularity, we consider player reviews and ratings, which provide insights into the slot’s entertainment value and reliability. We also look at the game developers, as slots from renowned developers like NetEnt, Microgaming, and Playtech tend to be more popular due to their track record of quality.
Jackpot Size – The potential size of the jackpot is a critical factor for progressive slots. When evaluating jackpot size, we review current and historical jackpots, focusing on the highest payouts ever recorded for the slot and the average jackpot size when won while also considering the progressive nature of the jackpot.
Return to Player – The RTP percentage indicates the average amount of money returned to players over an extended period. A higher RTP is generally more favourable, and for progressive slots, we consider games with RTPs between 88% and 96%, favouring slots on the higher end of this range. We also assess the impact of the progressive jackpot on the base RTP, evaluating the overall fairness.
Frequency of Payouts – Generally speaking, not all progressive slot games payout with the same frequency. Some pay out more often, while others do not, and even though there is no science behind it, we take into consideration historical data to determine the best choice for our players.
Overall Gameplay – Even though these games offer such rewards, progressive jackpots are not won all the time. Because of that, we also consider the overall gameplay and entertainment factor of each progressive slot. This also includes visuals, graphics, and bonus features.

Types of Progressive Slot Jackpots
Progressive jackpots can be classified into several types based on how they accumulate and how widespread they are. Here’s a look at the main types of progressive jackpots:
Standalone Progressive Jackpots
Standalone progressive jackpots are confined to a single slot machine, and the jackpot amount increases as players wager on that specific machine, with a small portion of each bet contributing to the jackpot pool. Since the jackpot is fed by a single machine, it typically grows more slowly and results in smaller jackpots compared to other types. These jackpots can be easier to win due to the limited pool of contributors.
Local Progressive Jackpots
Local progressive jackpots are linked across multiple machines within a single casino or a limited geographic area. These machines are networked together, contributing to a shared jackpot pool. Local progressive jackpots feature casino-wide contributions, meaning bets placed on any of the linked machines contribute to the jackpot. The pooled bets from multiple machines allow the jackpot to grow larger and faster than standalone jackpots, making it a more appealing choice. The combination of a limited player base and multiple contributing machines provides a balance between jackpot size and winning odds.
Wide Area Progressive Jackpots
Wide area progressive jackpots are linked across multiple casinos, sometimes even spanning different regions. These jackpots are connected through a network, allowing a larger pool of players to contribute. Their multi-casino contribution, with bets from machines in different casinos, often operated by the same gaming provider, feeds into a common jackpot pool. The extensive player base contributes to rapid jackpot growth, often resulting in very large payouts. However, due to the larger number of contributors, the odds of winning these jackpots are lower compared to standalone and local progressives.
Networked Progressive Jackpots
Networked progressive jackpots, also known as pooled or linked jackpots, are similar to wide-area progressives but can extend even further, often being linked across online casinos globally. These jackpots accumulate contributions from a vast network of machines, both online and offline.
Networked progressive jackpots feature global contributions, with bets from players around the world, across various online casinos contributing to the jackpot pool. The global player base and high volume of bets lead to some of the largest jackpots in the industry. While the potential payouts are massive, the sheer number of players contributing to the jackpot significantly reduces the odds of winning.

Progressive Slots Developers
Considering the popularity and appeal of the best progressive jackpot slots, there is no wonder why so many capable developers are starting to develop their own progressive jackpots or collaborating with some of the most popular and sought-after ones. Let’s take a look at some of the best game developers with progressive slots.
Microgaming
Microgaming is one of the leaders when it comes to slots in general, but particularly slots with progressive jackpots. It is also the developer of the world’s biggest and most frequently won Mega Moolah progressive jackpot, which has been implemented in many of its best online slots. Microgaming’s popularity among players because of its high-quality games also plays a big role in this, making it an essential element of countless online casinos. Since its rebranding, Microgaming stopped existing as such and has also slowed down in its release of progressive jackpot games. However, the Mega Moolah’s seed value of £2,000,000 still makes it a top choice.
Playtech
Playtech is another titan in the online slot industry, known for creating some of the best and most played online slot games. On top of that, it is also famous for its progressive jackpots, as well as the interesting twist in which it implements them. Namely, Playtech’s progressive jackpots are available only through its most popular slot series – Age of the Gods. It currently has over two dozen individual games, each one offering the potential to earn some exceptional wins. The best part about it all is that Playtech continues to create new Age of the Gods slots for even more fun and opportunity, with the Ultimate Power Jackpot having a seed value of £100,000.
Relax Gaming
Relax Gaming is a big name in the iGaming world, but it is a relatively new name in the progressive slots world. It became known for creating the popular Dream Drop jackpot network back in 2022 and took the online slot world by storm. You can now find many Relax Gaming slots that offer it, and surely there will be many more to come. Relax Gaming combines new Dream Drop slots as well as remakes of already existing and popular ones. It includes 5 linked jackpot pools – Rapid, Midi, Maxi, Major, and Mega. So far, there have only been 12 progressive jackpot winners of the Mega Jackpot, which can reach up to £3,000,000.
Blueprint Gaming
Blueprint is another titan that is known for creating some of the best progressive jackpot slots. Unlike Relax Gaming, for example, which is famous for frequent and high-quality releases, Blueprint is a bit slower when it comes to new progressive slots. It has created the famous Jackpot King jackpot that offers three separate pools – Regal, Royal, and the Jackpot King. There are countless slots that include it, and currently, it has a value of £100,000+, while the biggest recorded win is more than £7,000,000.

Important Terms to be Aware of in Progressive Slots
Even though they play out as regular slots and offer the same gameplay, plus a special jackpot round, progressive slots differ in many ways. This is especially true when it comes to the terms and conditions surrounding the progressive jackpots. Let’s explore them in more detail now.
Eligibility to Win
It’s important to be aware of how to qualify and to qualify for the progressive jackpot. Usually, you will need to place the maximum allowable bet, as anything below it will not include the option to trigger the progressive jackpot round..
Winning the Jackpot
The jackpot is typically triggered by specific combinations of symbols, activation of a particular feature, or sometimes by random chance. Each game has its own conditions for winning, which are clearly defined in the game rules. This is something you need to be familiar with in order to know what to expect.
Payout Structure
You also need to be aware of the payout structure. The progressive jackpot is usually paid out either as a lump sum or an annuity. The terms of the payout, including whether it is in cash or credits, should be clearly stated. In addition to the main jackpot, progressive slots often feature secondary prizes or bonuses for other winning combinations.
Terms and Conditions
Progressive slot machines come with specific rules detailing how the jackpot can be won and the requirements for eligibility. These rules should be clearly displayed on the machine or online. Winners typically undergo a verification process to confirm their win and ensure compliance with the game’s rules, which may include identification checks. There may also be a claim period within which the jackpot must be claimed; otherwise, it could be forfeited.
Game Fairness and Integrity
Progressive slots are regulated by gaming authorities to ensure fairness. The games must use random number generators to ensure that outcomes are random and not manipulated. Casinos are required to provide transparent information about the odds of winning the jackpot and the current jackpot amount.
Jackpot Reset
After a progressive jackpot is won, it typically resets to a predetermined amount, which can vary by game or casino. Make sure to be aware of the value of the progressive jackpot beforehand, so you don’t waste time and money on small jackpot prizes.
Casino Policies
Different casinos may have additional rules or variations for their progressive slot games. It’s important to review the specific terms and conditions associated with each casino’s progressive slots to fully understand the game’s requirements and opportunities.

First and foremost, it’s crucial to thoroughly understand the rules of the game. Different machines may have varying rules, especially when it comes to qualifying for the jackpot.
