How we rank the best progressive slots casinos

Progressive slots are like regular slot machines, but with a special twist: they have a growing jackpot that keeps getting bigger as more people play. Every time someone makes a bet, a small part of that bet goes into the jackpot. This continues until one lucky player hits the right combination of symbols and wins the entire jackpot. It’s like a lottery where the prize keeps increasing until someone wins it. Now you understand what they are, let’s have a look at what goes into ranking the best progressive slots casinos in Ireland.

Game collectionThe diversity of progressive slots casinos is crucial, as it offers something for everyone. Casinos that provide a comprehensive range of games, with different themes, are more enticing and therefore more likely to be recommended by us.
Additional experiencesWhile we’re obviously talking about progressive slots here, there still needs to be complementing experiences – namely in the form other gambling markets, like table games and live dealer options – as the holistic experience is what keeps punters there. Go for the progressive slots casinos, stay for the holistic and varied range of other ways to gamble…or something like that.
Mobile experienceThe convenience of gambling on mobile is not to be overlooked. In fact it’s the number one way punters are choosing to play progressive slots, and all other forms of gambling for that matter. Therefore, a decent app is not just a nice-to-have, but an essential item in a casino’s arsenal that are looking to be the best in their field. Apps should cater for all markets, events, and features equally found on the site, including progressive slots. We consider all of this before we recommend anything.
User-interface and designSlots are a very visual way to bet, with all of the themes, colours, and sounds simply enhancing the bettor’s experience. Casinos that have state-of-the-art graphics and the latest designs, along with an intuitive and easy to navigate user-interface, will be looked upon favourably.
Competitive return-to-player (RTP)Return to Player (RTP) refers to the percentage that will be returned to a player depending on funds deposited during the game. Progressive slots casinos in Ireland that offer a competitive RTP demonstrate a commitment to fair play and that they care that their customers have a nice chance of scoring some profits. As such, we’ll only recommend sites who consistently aim to offer the most competitive RTPs. If they’re partnered with established gaming providers, like Eyecon Games or NetEnt, that’s a plus.
Networked jackpotsNetworked jackpots are a type of progressive jackpot system used the slots. Instead of a single game contributing to the jackpot, multiple games or machines in different locations are connected to a shared jackpot pool. This allows for much larger jackpots to be built more quickly and provides players with the potential for even bigger wins. Casinos that offer progressive slots linked to wider networks, increasing the jackpot size and frequency of wins, are more likely to do well in our ranking.
Bonuses and promotionsWho doesn’t love a freebie? The answer is of course nobody, which is lucky, because all online Irish casinos will have bonuses and promotions regularly running. The most ubiquitous is the much-coveted welcome bonus, which can take the form in free spins, cashback offers and more. We look at the value of the offer as well as the terms and conditions, to ensure sure they’re achievable and fair for punters.
Reputation and reviewsThe reputation of a progressive slots casino is crucial to shaping a picture of how good they are. We do this by looking at reviews from customers on sites like TrustPilot, which can offer a flavour of what an Irish casino’s pros and cons are, while we also keyword search for progressive slots to drill down even further.
Payment methods and payoutsVaried payment options for bettors to deposit and withdraw funds are a must. We expect to see debit card and credit cards as standard, while e-wallet solutions – Apple Pay or Google Pay – should also be readily available. Casinos that also offer other payment platforms like Neteller or Skrill, are also a plus. Withdrawal speeds and processes should be seamless too, without punters needing to wait longer than needed to receive their winnings.

888 Casino

New online casinos seem to be popping up all the time these days. The market is very competitive, to say the least, but there stands one online casino that has stood the test of time and that’s 888 Casino. Starting life way back in 1997, this old hand has been serving slot enthusiasts for many a year. But what is it about their progressive slots that keep players coming back? Let’s take a look.

The first thing you’ll notice about 888 Casino is the game library isn’t as big as other online casinos. For instance, where LeoVegas has over 2500 games, 888 Casino has just over 200. But whilst the games might be fewer here, they are quality offerings and players will find enough to keep them happy.

The casino layout is very easy on the eye with vibrant green shining against the matt black background. It’s very easy to navigate too, with a side menu giving you access to all the different sections of the casino. For the progressive slots, just click on ‘Jackpots’ and you’ll be taken to a page with a fantastic range of games categorised under Daily Jackpot, 8 Hour Jackpot, Twilight Jackpot, Mega Jackpots, Red Tiger Jackpots,  Big Playtech Jackpots and then directly under those, you find the full list of progressive jackpots.

The range of progressive jackpots at 888 Casino is very impressive, presenting players with plenty of chances to win life changing amounts of money. The Jackpots range from a few hundred euros to over a million in some instances. It’s definitely a case of quality over quantity when it comes to jackpot slots at this casino!

Here are some of the current big hitters available for you to play:

Progressive SlotCurrent Jackpots (at time of writing)
Millionaire Genie Megaways€1,740,439
Mad Max Fury Road€1,740,439
Irish Riches€1,740,439

A Nightmare on Elm Street€9,447
Leprechaun’s Rainbow Megaways€3,234
Book of Scrolls€10,079
Age of Gods: God Storms€122,824
Ronnie O’Sullivan: Sporting Legends€572,637

Away from the progressive slots and jackpots, there is a very competitive welcome package for new players. Sign up to the casino and make an initial deposit of €10 and get a 100% bonus up to €100. And if that isn’t good enough, you get 88 free spins just for signing up, no deposit needed!

So, taking all of this into account, we think 888 Casino is a great place to play progressive slots and chase those massive wins. Sure, there might not be as many games available as some other online casinos but everything they do have here is quality and some of the jackpots are massive. With the added bonus of a very good welcome package and an easy to use casino interface, we have no problem recommending this old and trusted name to Irish players.

777 Casino

Established in 2015, 777 Casino is run by renowned casino group 888 Holdings, so right off the bat you know you’re in good hands. The casino itself has a retro aesthetic which we quite enjoyed and the site is fast and easy enough to navigate and find your way to the gaming lobby and the dedicated slots page. It’s here you’ll find the great selection of progressive slots on offer, powered by several of the best game providers in the business.

Across the top of the Jackpot Slots page, you see a scrolling list of all recent winners and how much they have bagged. Below that, we get to see the great games on offer. Here’s a selection:

GameJackpot (at the time of writing)
Wolf Run€1,201,975
Cleopatra MegaJackpots€1,201,975
The Ruby€35,315
Superfast Hot Hot€112,769
Basic Instinct€129,365

As you can see, progressive jackpots can run to huge amounts including the game Wolf Run, which has a current prize pot of over a million euros! Other popular progressive slots include Pyramid Fortunes, Pixies Forest 2, Age of the Gods, Africa Goes Wild, Patrick’s Jackpot and Halloween.

There is a range of promotions at 777 Casino, all designed to help you on your progressive slot playing journey. These include the chance to win a progressive roulette jackpot, Spin Boosters and you can also join the Premium Club, where players earn points every time they play a game. Collect enough points and you can trade them in for a range of bonuses.

With its fantastic range of progressive slots, high end jackpots, appealing promotions and ease of use layout, we really enjoyed our time at 777 Casino. Sure, the range of games isn’t as big as some other sites but what they do have is top quality.

BetVictor Casino

An established and respected name in the Irish online casino community, BetVictor has over half a million players worldwide. The casino design is stylish and simple. All the effort has gone into providing the best gaming experience possible and the site design clearly shows that’s the case. Everything is easy and finding your way to the range of progressive jackpots takes next to no time. All you have to do is enter the casino from the sidebar, then click on ‘Megaways’ from the centre navigation bar and you’re presented with a wide range of games to choose from. There are some big hitters here too, including Eye of Horus Megaways Jackpot King, which at the time of writing, has an incredible jackpot of €1,601,499!

Other progressive jackpots include:

GameJackpot (at the time of writing)
Dynamite Riches Megaways€10,505

Away from the great range of progressive slots, BetVictor offers new players a very attractive welcome bonus, including a €50 bonus to use on selected slots when you make an initial deposit of €10. This is a great offer which can help you get your progressive slot playing off on the right foot.

With its appealing welcome offer for new players, fantastic range of progressive slots with some mouth watering prize pots plus the nicely designed, user-friendly layout, we think Irish players will have fun at this casino. The only downside we could see is that maybe players would be tempted by other casinos with a larger variety of games and similar sized jackpots.

What are Progressive Slots

Every online casino worth it’s salt will have a host of slot games for players to enjoy. Some even have thousands to choose from and amongst the fun selection, you will find progressive slots. With progressive slots, unlike regular slots, the jackpots are not fixed amounts. In other words, the more money spent on the game, the bigger the jackpot will rise and it will keep rising until it is won, then it will reset and the whole process will start again. Some progressive slots will cash out when the jackpot reaches a pre-determined amount and some will keep going and going, sometimes reaching unbelievable prize pots.

What are Progressive Jackpots

Progressive jackpots are the prize you can win from playing progressive slot games. They are progressive because when you pay to play a game, a percentage of your stake is added to the jackpot. The more people play, the more the jackpot increases.

Let’s take a look at the different elements that make progressive jackpots work.

The ContributionEvery time you place a bet while playing a progressive jackpot game, a small portion of your wager is allocated to a separate fund dedicated to fueling the jackpot or jackpots. The exact percentage varies depending on the game and the casino hosting it.
The SeedEvery progressive jackpot has to originate from a specific starting point, as no player would find a jackpot of €0 or €10 enticing. This initial amount is known as the “seed” and is guaranteed by the casino or game supplier.  
The PrizeA progressive jackpot is a constantly increasing sum that grows as the game is played. While the million euro progressive jackpots attract the most attention, it’s important to note that progressive slots come in various sizes and shapes, with some even featuring their own smaller progressive jackpots, often less than €1,000 in value. Historically, these jackpots have been won, on average, every 10 weeks, adding an element of excitement and anticipation to the gameplay.  

Strategies for Winning at Progressive Slots

What appeals most about progressive slots and jackpots is the opportunity they give to win potentially life changing amounts of money. It’s not all just down to luck either. There are strategies you can adopt to improve your chances of winning. Let’s take a look.

  • Manage your money.

Always play with a budget in mind and stick to it. Try not to get carried away and spend more than you can afford. Try betting smaller amounts to increase your chances of regular wins and never bet big unless you can afford to.

  • Know When to walk away.

This ties into managing your money. It’s no good getting carried away and wagering more than you wanted to. You have to know when enough is enough and it is time to walk away. Having discipline like this is not only good for your bank balance but it will also elevate your overall enjoyment of the game and reduce stress.

  • Know the odds.

All progressive slot games are different. It’s important to learn about each one and get to know the odds. You can research each game online and maybe even join player forums and group chats. You can also play demo versions of some games, which will help to improve your game.

  • Make sure you know the rules.

Each game will have rules easily available and knowing the rules will increase your chances of being successful. Again, you can practise some games in demo mode, which can really help you to get to grips with the rules.

  • Don’t stick with one slot.

Don’t be stubborn and spend all your money on one game. Some casinos have hundreds of progressive slots and each game is different, with different rules and different odds of winning. If you are unsuccessful with one slot then try another.

Types of jackpot slots

There are a wide variety of progressive slots, catering to the many preferences of casino players. But we can break these types down into 5 areas:

Standalone Progressive SlotsThese are individual slot games with their own progressive jackpot. The jackpot is dependent on the percentage of the bets placed on that specific game. You will find that standalone progressive slots have smaller prize pots in comparison to other jackpot slots but they still offer the chance to win big.
Local Progressive SlotsWith local progressive slots, they are connected to a network, specific to the online casino or even a group of casinos. The jackpots are linked and all will increase together, funded by a percentage of bets placed on all slots in the chain.
Wide Area Progressive SlotsThese are like local progressive slots but they are linked across multiple casinos. The jackpots are determined from bets placed on games across various casinos and all jackpots in the link increase together.
Network Progressive SlotsNetwork progressive slots are similar in nature to local and wide area slots but they are specific to one casino. All the bets are pooled together across every game in the link and they increase together. The jackpots for these progressive slots can be substantial.
Random Progressive SlotsRandom progressive slot games are unique in nature as the jackpots are awarded randomly regardless of what happens in the game. The jackpots can drop at any time, raising the levels of excitement for players.

We have discussed several progressive slots already but which are the most popular amongst Irish players? Here are 5 of the best available today.
