What is a Progressive Jackpot Slot?
Progressive jackpot slots stand out thanks to huge potential prizes that increase over time as players spin the reels. Unlike standard jackpot slots, which offer fixed prizes, progressive jackpots grow bigger until a lucky player hits the top prize.
These slot games take a small percentage of every bet placed and add it to a growing prize pool, meaning jackpots can grow to life changing amounts. In fact, virtually all of the biggest ever casino wins have been from playing progressive slots. As a result, these games are incredibly popular, especially at online casinos.
How Do Progressive Slots Work?
Progressive slots work in more or less the same way as any other online slot machine. However, they introduce a unique feature, the progressive jackpot. Before you start spinning, you should know how these games work and what to expect to make the most out of your jackpot slot experience.
Jackpot Seed
The seed is essentially the foundation of the progressive jackpot. Games never start with a jackpot value of £0, or else no one would want to play. The casino or game provider offers up a seed or starting amount, meaning the jackpot value is never below this figure. For example, the Mega Moolah seed value is £2 million for the mega jackpot.
Jackpot Contribution
Every time someone makes a spin of a progressive jackpot slot, the jackpot value grows slightly. This is because the game takes a percentage of each bet and adds it to the prize pot. The more people play, the higher the jackpot can get.
Jackpot Bonus
The progressive jackpot keeps getting bigger until it’s won. Generally, the prize will be triggered at random during the slot’s bonus round. The exact rules on how the jackpot is awarded will depend on the game, but it’s always a random event.
Types of Progressive Jackpots
Although all progressive slot games have a progressive jackpot prize pool, they often work in different ways. There are a few main types of progressive jackpot slots:
- Standalone – This type of progressive slot uses a single jackpot prize that is unique to that game. However, since the game will be available at many UK online casinos, bets from players across all participating sites will contribute to the prize pool.
- Network – Networks offer the same progressive jackpot across multiple games and multiple online casinos, ensuring faster growth as more players can contribute.
- Tiered – Some progressive jackpot slots offer multiple jackpots with tiered values available to win. For example, mini jackpot prizes may be worth hundreds of pounds, whereas mega jackpot prizes can be worth millions.
- Timed – Although most progressive jackpots are won at random, some are timed to be won within a specific time frame. For example, daily jackpots must be won every day.

Progressive Slots Developers
There are a lot of different casino developers that produce progressive jackpot slots. Each has its own unique style and features that help the games stand out. We’ve picked out some of the best progressive slot developers.
Microgaming Progressive Jackpot Slots
Microgaming is one of the best-known casino software developers. The company was formed in 1994 and has produced some of the best games available today. Perhaps best known for creating one of the most iconic progressive jackpot series of all time, Mega Moolah, Microgaming also has many other progressive jackpot slots in its portfolio.
Mega Moolah offers tiered jackpots, including a mega jackpot, which is seeded at £2 million. It’s also responsible for some of the largest casino wins of all time. It was such a hit that Microgaming has since released dozens of different Mega Moolah games.
NetEnt Progressive Jackpot Slots
NetEnt, the Evolution Gaming-owned slot developer, is known for developing some of the most popular slots online, such as Starburst and Gonzo’s Quest. However, the slot developer has also created several exciting progressive jackpot slots over the years. The most well known of these is probably Mega Fortune, which offers three different jackpots, the largest of which is seeded at £1 million.
While Mega Fortune might be the most popular NetEnt progressive jackpot, the developer offers several other games with progressive prizes, including Hall of Gods, Arabian Nights and Mega Fortune Dreams.
Playtech Progressive Jackpot Slots
Playtech was founded in 1999 and produces software for both online and land-based casinos. The developer has created more than 1,000 games, including a long list of popular progressive jackpot slots. These include the hugely popular Age of the Gods series, which mixes mythology with massive winning potential.
Age of the Gods originally came out in 2016, but since then, Playtech has launched over 30 different slots in the series, all featuring unique gods, bonus rounds and progressive jackpots. The largest of these jackpots, the Ultimate Power, is seeded at £100,000.
Other Software Providers
Aside from these three providers, plenty of other software developers also produce their own progressive slots. IGT is well known for its land-based and online progressive slots, including the Wheel of Fortune slots.
There’s also Red Tiger, which offers Daily Drop and Super Drop progressive jackpot network games. Blueprint Gaming also has its own progressive jackpot network known as Jackpot King, which can be linked to multiple games from different providers.

How to Win Progressive Jackpot Slots
Like all online slot machines, progressive jackpot slots are completely random, and there is nothing you can do to guarantee a win. However, there are things you can do to boost your odds. Most importantly, remember to look up the specific rules of your preferred game before joining a top rated online casino with progressive jackpot slots. Let’s look at the example of Mega Moolah:
- Choosing your bet size – Before you play, select your bet size. Some progressive slots, including Mega Moolah, give you a higher chance of triggering the Mega jackpot if you play with the max bet.
- Spinning the reels – Spin the reels and enjoy the game. It works the same as any other slot, where you match symbols along paylines to land wins.
- Bonus feature – If you’re lucky enough, the bonus game can trigger at random on any spin. You’ll then get to spin a wheel, and it’s possible to win any of the four jackpots.
Tips for Playing Jackpot Slots
Jackpot slots are determined by random chance, but there are still steps you can take to maximise your chances while playing:
- Managing your bankroll – Your chance of landing a jackpot is very small, so it’s important to manage your bankroll carefully to make sure it lasts.
- Understanding game mechanics – Always look up the volatility, RTP and game rules before you start spinning to ensure you know how the game works.
- Check the jackpot size – You can see when the jackpot was last won and its current value before you play. Try to pick the games with the biggest jackpots to maximise the value of your spins.

Responsible Gambling
It’s important to always play responsibly while enjoying progressive jackpot slots. Remember that your chance of winning a jackpot is incredibly low, and you should treat these games as a form of entertainment rather than a chance to make money.
