Best Irish Online Slot Sites - 2022

How We Choose the Best Irish Slot Sites

We approach our recommended lists as you would hope we do: with our users foremost in our minds. There are a number of factors players need to consider before selecting an Irish slot site, and we look at them all before listing an online casino on our site.

You’ll have your own ideas on which areas are the most important – from the best welcome bonuses to the widest variety of casino games – but we can help steer you in the right direction by laying out all the information you need. Here are some of the critical areas we assess.

Licensing

Licensing is the first port-of-call in our online casino reviews. Unlike other countries, Ireland doesn’t have one singular regulator overseeing its gambling industry. This isn’t to say that gambling in Ireland is the Wild West; instead, Ireland issues licences to its operators via other approved gambling jurisdictions, such as the UK Gambling Commission or the Malta Gaming Authority.

Every casino site you find on TopRatedCasinos holds a valid licence, and to stay safe, you should never place a bet at an unlicensed casino. To do so would be to open yourself up to unfair practices, and leave you susceptible to malicious online threats. 

Slot Catalogue

Gambling is a form of entertainment, so users want to play at a casino that can deliver this through an eclectic mix of casino games. Not only does this include a variety of slot machines, table games, and live dealer action, but also depth within these titles. For example, does the casino offer plenty of blackjack and roulette variations, in addition to the most popular editions?

Among the best online slot games of ‘2022’ include Bonanza Megaways, Eye of Horus, and the intriguing Hell’s Kitchen, all of which include bonus rounds.  

Software Developers

We work independently of software developers, recommending casinos that host games from all the best developers in the world. This means we can recommend our users the best choices in terms of gameplay, bonus features, and aesthetics from both the most established in the business, and exciting up and coming talent. 

Bonuses

Bonuses are often a key priority on many players’ lists and they make up a critical part of our reviews of the top Irish slot sites. As we’re predominantly dealing with online slot games here, free spin bonuses are perhaps the most relevant, but we take a look at the full suite of player bonuses, weighing up their frequency, quality and accessibility.  

Mobile

Mobile-optimised websites that can adjust to the user’s browser preferences are now considered a minimum requirement for online casinos. The best mobile casinos will also have downloadable apps available on different operating systems, and these sites rank well in our list of recommendations.

Customer Service

If there are any problems relating to your account, you’ll want the security of knowing you can rely on great customer service. This involves friendly staff available throughout the day and through a variety of different channels. 

The Different Types of Online Slots

The best slot sites seen on this page have four major forms of slot games that you can play. These are explained in detail here:

Progressive Slots

Progressive casino slots games are a great way to hunt for those big jackpot wins. Each time a player makes a spin on a progressive game, the total jackpot increases until it is won by a player.

Classic Slots

These are the pub slot games classics that have made their way into the online slots experience. These are usually three-reel games, and the total number of payout lines for these slots can be significantly less than the modern-day games. The sites on this page do support these games, which only adds to the competition of our search for the best online fruit machines.

Mega Spins

This is a form of slots where you can play several games at once, and the number of reels that you can spin sometimes can go up to 45. This is a rather large amount, and players enjoy mega spins due to the excitement of playing so many slot games at once, as well as the potential for jackpot wins.

Video Slots

Video slots are where you can find themed slot games, great animations, in-play bonuses, and some rather cool sound effects. Some examples of these games include Rainbow Riches, Starburst, Deal or no Deal games, and hundreds of others. These forms of games also offer the largest number of reels on the best slot sites, and the pay lines are the highest out of the four categories.

How to Play Online Slots

It is incredibly simple to get going with the best online fruit machines.

1) Check the Paytable

A paytable shows you everything you need to know, including the return to player (RTP), how much you can win depending on your bet, and your minimum and maximum stake options. You’ll also be able to find out more about bonus features here too.

2) Set your Stakes

Slot games usually have virtual coins that represent a real money value. Make sure your coin value suits your bankroll – don’t gamble more than you can afford to lose.

3) Select your Paylines

Most slot games these days feature multiple paylines. Betting on more paylines can give you a better chance of winning more money, however, you could just as easily lose.

4) Spin the Reels

Ready to go? Simply click spin. If you get lucky, you’ll know about it; the extravagant visuals will make it very clear and payouts are made immediately.

Best Slots to Play in Ireland in 2022

With so many options out there, it can be hard to know where to start when you’re looking to play an online slot. To help you out, we’ve listed some of the most popular titles below to offer a little inspiration. 

Still one of the most popular online video slots of all time, we’d be remiss if we didn’t include Starburst on our list of top slots to play in Ireland. Frequently featured in free spins bonuses across the best casino sites, this NetEnt title from 2012 combines the common five-reel, three-row format with a glamorous space theme.

One perk of Starburst is its expanding wilds, which stay in place while the rest of the reels are re-spun. There aren’t a lot of other bonus features on offer here; Starburst lacks a free spins round or any unique gameplay mechanics. That said, it must be doing something right as it remains a mainstay in the hearts and minds of slots fans. 

Second on our list is another slot title commonly associated with free spins. Released by Play’n GO in 2016, Book of Dead marks the second title in the Rich Wilde series which follows the eponymous archaeologist on his adventure to uncover the ancient riches of Egypt’s past. 

Just like Starburst, Book of Dead uses a 5×3 format and offers 10 paylines, but the bonus features are where it differs. There’s a free spins round triggered by the wild scatter, and a gamble feature with the potential to double or quadruple your win — or lose it entirely!

Marine aficionados will enjoy Bigger Bass Bonanza, a 2021 sequel from Pragmatic Play. The first difference you’ll notice from the original title is an extra fourth row, giving players a total of 12 paylines. The scatter symbol triggers up to 20 free spins, during which the Fisherman shows up to collect any money symbols and add them to your payout. The Big Fish symbol can award up to 4,000x your stake, and the wild meter can trigger respins and 2x–10x multipliers.

All wrapped up in a funky underwater theme, Bigger Bass Bonanza comes with a solid RTP and high volatility, so players are likely to see less frequent, larger payouts.

Another slot from Pragmatic Play, Wolf Gold transports players to the Wild West where they’ll face up against wolves, big cats, and eagles. There are 25 paylines in total across five reels and three rows, with a large fixed jackpot of 10,000x your bet. 

Landing three scatters activates the free spins round and it can be retriggered an unlimited number of times. There’s also the money respin round, where the reels are occupied by Moon symbols and empty spaces — land 15 Moons and you’ll swipe the Mega Jackpot.

A classic love story meets a gothic vampire theme in Immortal Romance, a deeply immersive slot from Microgaming. The title is hugely popular, likely due to its wealth of bonus features to keep players interested. Alongside wilds which can randomly expand, the Chamber of Spins bonus round gives players a number of free spins. There are four variations — one for each in-game character — with different gameplay quirks, such as cascading reels or payout multipliers.

Throw in a brooding soundtrack, an intriguing plot line, and 243 different ways to win, and it’s easy to see why Immortal Romance is one of the top vampire slots around.

Fans of Blueprint Gaming’s Fishin’ Frenzy slot will love the 2019 Megaways version — this thrilling format brings the total possible paylines to a whopping 15,649. There are six reels to spin, and each one can expand to fit up to seven symbols.

Fishin’ Frenzy Megaways features a bonus round triggered by landing at least three scatters on the reels, rewarding players with 10–50 free spins. If you’re looking for a Megaways slot with a nautical theme, look no further!

Gonzo’s Quest Megaways is the second slot on our list to feature the payline-bolstering mechanic. This time around, it’s been added to NetEnt’s beloved title which popularised the cascading reels mechanic now found in many other slots. 

With 2–7 slots on each of the six reels, there’s a maximum of 117,649 ways to win. While the Megaways version of Gonzo’s Quest looks much like the original, there’s the addition of the randomly triggered Earthquake feature where low-paying symbols are removed from the reels to make way for higher-paying ones.

Part of Playtech’s mythology-themed Age of the Gods series of slots, God of Storms gives players the chance to win one of four progressive jackpots when they spin its 5×3 reels. Like other entries in the franchise, God of Storms’ graphics are crisp and colourful, immersing players in Ancient Greece. 

Another exciting mechanic is Wild Wind Re-Spins, where the Stacked Ship wild symbol makes its way across the reels, propelled by the titular God of Storms. The game’s volatility is low, and although there’s no free spins round, you’re likely to see small, frequent wins which can be boosted by payout multipliers.

One of the more uniquely themed titles on this list, Chilli Heat from Pragmatic Play is a 5×3 slot with a Mexican twist.  On each of the five reels, you’ll find mariachi musicians, peppers, bottles of Tabasco, and shots of tequila, and the potential to win one of three jackpots.

Landing six money bag symbols activates the re-spins feature, and players can also take advantage of a free spins round where low-paying symbols are removed from the reels. Chilli Heat has medium volatility, so it’ll suit players of all budgets — even those with a low tolerance for spice!

We couldn’t have a list of best slots and not include Mega Moolah, a Microgaming title responsible for dozens of record payouts. Although the RTP in the base game is low, players spin Mega Moolah’s reels for a chance at one of its three progressive jackpots — the largest of which once paid out a record €19.4 million.

There’s no doubt there are newer and more exciting slots available. Mega Moolah was released in 2006, after all. That said, it’s still arguably one of the most famous jackpot games, and we’re fond of its jocular safari theme.

Book of Ra

Novomatic’s Book of Ra is one of the best online slots available to Irish players, and features at all the top slot sites. Released back in 2005, this Ancient Egyptian-themed slot still holds up today. It features 10 paylines across its 5×3 slot reel and is highly volatile, so there may be some winless runs before you hit a large payout.

In the game, you’ll join a handsome explorer in his quest to uncover the secrets lying beneath Egypt’s ancient pyramids. The explorer himself is the highest-paying symbol in the game — there’s a 500x payout if you manage to land five of him across a payline. 

The Book of Ra itself, meanwhile, is both the scatter and wild symbol for the game. Land three of these anywhere on the reels to unlock the game’s sole bonus feature, the free spins round. A special expanding symbol is chosen at random at the beginning of the round, giving you the chance to land multiple winning combinations. You’ll kick off with 10 free spins, but this feature can be triggered an unlimited number of times, so keep searching for that Book of Ra.

Mega Fortune

Mega Fortune features at all the top Irish slots sites, developed by NetEnt and featuring five reels and 25 paylines. It’s a progressive jackpot slot, with three different jackpots available during the Bonus Game feature: the Rapid Jackpot, Major Jackpot, and Mega Jackpot. The first two jackpots payout at least €50 and €5,000, respectively. The Mega Jackpot, meanwhile, paid out one of the biggest wins at a slot site ever in 2013 when one winner bagged €17.8 million.

Mega Fortune centres around a luxurious theme — the reels are adorned with expensive cars, jewellery and champagne, backdropped by palm trees and a swimming pool. The yacht serves as the Wild symbol and substitutes for all others aside from the bonus and scatter symbol — it’ll pay 400x your stake if you land five of them. 

Three or more champagne scatter symbols are required to activate the free spins round. Here you can play with 10 free spins and a multiplier up to 5x. Then, to make your way to the Mega Fortune bonus wheel — the main event — you’ll need to land three wheel bonus symbols on consecutive reels. From there, players spin the gameshow-style wheel to try and land cash prizes. There are plenty up for grabs but it’s the diamond arrow that leads to the ultimate prize.

How to Deposit Money at an Irish Slot Site

There’s no shortage of banking options when it comes to paying for your bet, with online casinos catering to a range of payment methods. Let’s break down the most popular.

Debit Cards

If you want a banking method that can offer fast withdrawals, debit cards may not be the choice for you. But if you want a steady, reliable and familiar option, then this is where to start. Debit cards are the most widely used payment method at online casinos and are accepted at almost every Irish slot site. 

e-Wallets

E-wallets are a popular payment choice at online casinos, with punters drawn to their high deposit and withdrawal limits and quick payout times — in some cases, withdrawals happen in an instant. PayPal, Skrill and Neteller lead the way and are all available at many sites. 

Prepaid Cards

Prepaid cards, such as Paysafecard, work similarly to credit cards, but don’t require any bank information at the point of transaction. Instead, users authorise their payments via a 16-digit PIN, and can enjoy high limits on deposits. However, prepaid cards don’t allow for withdrawals for gambling transactions, so you’ll need to use them alongside another banking option if you want to take home your winnings.

Pay by Mobile

Pay by mobile is a system that simply requires a contracted mobile phone number to pay for your bet. At the point of transaction, key in your number, and your mobile network provider will pay for your bet on your behalf before charging it to your monthly bill. Boku is the leader in this space, but again, pay by mobile services can’t facilitate withdrawals, and there are also strict limits on deposits.

Top Software Developers at Irish Slot Sites

This is by no means an exhaustive list, but here are some of the biggest software developers to look out for.

NetEnt

NetEnt is a master of online slot games, and is one of the most successful game developers in the industry, so it’s pretty much a given you’ll find this developer at all the top Irish slots sites. The veteran’s legendary titles include Starburst and Blood Suckers, but perhaps its most famous is Gonzo’s Quest, a game which popularised the cascading reels mechanic found in many slots today. 

But the innovation didn’t stop there: NetEnt made its first foray into virtual reality with Gonzo’s Quest VR, and since it was acquired by Evolution Gaming in 2020, the franchise has dipped its toes in the live casino world with Gonzo’s Treasure Hunt, an exciting mix of live and slots-style action.

Pragmatic Play

Another major hitter in online casino games, Pragmatic is one of NetEnt’s main competitors, producing outstanding slot machines alongside its expert live dealer offering. Its most popular slot games are Wolf Gold, The Dog House, and John Hunter.  

Many slot enthusiasts favour Pragmatic Play titles for their varied mechanics — you’ll find thrilling features like multi-level bonus rounds and multipliers, scatters and stacked wilds, respins and free spins, and both progressive and fixed jackpots. 

Play’n GO

Play’n GO develops games that focus on the mobile casino market. Diamond Vortex, Riddle Reels, and Rally 4 Riches are three of its most popular titles you’re likely to find at the best online slot sites in Ireland.

Beautiful design is a key feature of any Play’n GO slot — the vibrant illustrative style is augmented by carefully crafted sound and flourishes of background animation, immersing players no matter what the central theme is.

International Game Technology (IGT)

Commonly known as IGT, this developer has been around since the 80s, expanding and evolving to meet the changing habits and technology of the gaming world. IGT’s best slots include Cleopatra, Da Vinci Diamonds, and Pharaoh’s Fortune Fortune. 

Those looking for jackpot slots should keep their eyes out for IGT’s MegaJackpots titles — these games are part of a progressive jackpot network that occasionally pays out millions.

Playtech

Another slot stalwart, Playtech has been around since the turn of the millennium, and its Playtech ONE omnichannel solution powers many online casinos today. The developer is responsible for the massively popular Age of the Gods slots series — now almost 30 titles strong if you include the Norse spin-off — but has also developed branded games like The Dark Knight and Justice League.

Microgaming

Microgaming is headquartered on the Isle of Man and has almost three decades of experience in the online casino industry. Along with popular slots like Immortal Romance, Thunderstruck, and branded titles like Game of Thrones, Microgaming also created Mega Moolah, a progressive jackpot slot famous for some immense payouts reaching nearly €20 million.

New Slot Sites

While you might be tempted to sign up with some familiar faces, new casinos are great options too. New slots sites often bring fresh site designs to the table, as well as player-friendly offers and features like generous cashback, player tournaments, or combined no wagering, no deposit deals. PlayOJO is a great example — since it launched, the site has offered all bonuses free of wagering requirements, meaning players can instantly withdraw any winnings with no limit on the amount.

While new slots sites may not have as many payment options as the more established operators, they’re often designed from the ground up with mobile devices in mind. They’re just as safe and reliable too, as long as you stick with a licensed site. Rest assured, all our recommendations — both old and new — hold full licences from reputable regulatory bodies like the UK Gambling Commission or Malta Gaming Authority. 

Another perk of new slots sites is access to the latest games from top slots developers. Here are a few of our recent favourites:

Love Joker

Love Joker is an instalment in the Play’n GO Joker slot series, offering players a seductive twist on the classic slot format. Featuring a 3×3 grid, you’ll find the usual fruit symbols covering the reels plus the Love Joker himself. When he lands, the respins round is activated and filling the meter grants a win multiplier between 2x and 125x. Varied gameplay is one reason we love to play new slot releases, and this bonus mechanic is a welcome addition to the tried and tested classic slot formula.

Snakes and Ladders Megadice

Everyone knows the popular board game of snakes and ladders. In Snakes and Ladders Megadice from Reel Kingdom, players spin the reels for a chance to activate the bonus round where they’ll work their way up a 12×12 grid, climbing ladders and avoiding slippery snakes to reach the top and claim a 1,000x prize. Picking up multipliers along the way can boost your payout, with a max win of 5,300x your stake in this highly volatile slot.

Queenie

Wild Streak Gaming released Queenie in February 2022. It’s themed around Alice in Wonderland and is played on a 5×3 grid with 243 ways to win. Any time you land a wild in the base game, there’s a chance to trigger the Wheel bonus round — prizes include a payout between 8x and 200x your stake, a random 2x–100x multiplier, extra wilds added to the reels, or the 50 free spins bonus round. You could also trigger the Jackpot Pick Me bonus game, where you’ll win 20x, 50x, 200x, or 4,000x your stake.

Mobile Slot Sites

We select casinos on our site that have excellent mobile capabilities, including the availability of first-rate mobile apps on both Android and iOS operating systems. If you can, we highly recommend signing up to a site that offers a native app.

Not only have they been developed solely for the mobile screen, providing users with great functionality and fast loading times, but switching on push notifications also offers the best way to keep up with all the latest bonuses and promotions.

Casino Bonuses for Slots

Online slots bonuses come in all shapes and sizes. As there are so many different kinds available, it can be difficult for new players to figure out which bonuses suit them best. In this article, we will address some of the main offers your Irish slot site could have in store for you. In the process, we hope you will gain a better idea of which bonuses could be up your street. 

We’ll also touch on some of the other factors influencing slots gameplay. Before opting in to any of these offers, always make sure you read the terms and conditions carefully to give yourself the best chance of making your bonus count. 

Matched Deposits

Matched deposits offer a way of boosting your account funds by a certain percentage. For matched deposit welcome bonuses, offers tend to be around 100% up to €100. Players making use of the full scope of this offer would therefore receive €200 from a €100 deposit, effectively doubling their money. 

Of course, one of the best things about matched deposits is that players can decide how much of the bonus they want to access. Although the offer might stretch to €100 or beyond, players are free to deposit whatever amount they’re comfortable with, providing it meets the minimum deposit. Sticking with the example above, players could choose to deposit €30 instead, receiving an additional €30 from the online casino.

For existing players, matched deposit offers will be less generous than the examples above. If you’re already a member, these offers are more likely to be in the region of 50% up to €50; if you wanted to use this offer in its totality, you’d receive €75 from a €50 deposit. 

Free Spins

Free spins may also be included as part of a welcome bonus, rewarding players for signing up with a bundle of bonus spins to use on selected slots. If you’re an existing player, these free spins bonuses tend to be unlocked by qualifying deposits, such as an offer of ten free spins when depositing €5. Free spins bonuses may also be tied to a specific game, such as 25 free spins to use on NetEnt’s Starburst. 

No Deposit Bonuses

The best slot sites will offer players no deposit bonuses – a reward issued to new players simply for signing up to the site, without the need to make their own deposit. These bonuses might come in the form of account funds or extra spins, but since they require no deposit on behalf of the player, their value will be smaller than matched deposits. Indeed, most no deposit bonuses are in the region of €5 or €10. 

Reload Bonuses

Bonuses targeted at existing players are known as reload bonuses, so-called because they indicate a ‘reloading’ of funds into the player’s casino account. As such, reload bonuses can take any form, including matched deposits, free spins, and promo codes.  

Low and No Wagering Bonuses

Some top slot sites will offer low and no wagering bonuses, which reduce or remove the limitations that wagering requirements cause. We’ll address what wagering requirements are in greater detail below, but essentially these bonuses reduce the need to make additional wagers before withdrawing any bonus winnings.

While low wagering bonuses have requirements lower than the industry average, no wagering bonuses remove these requirements altogether. 

Slot Payouts, Paylines, and RTP

No two online slot games are the same. Indeed, game developers use all manner of culture as inspiration for the creation and design of their games – from ancient civilizations, to classical mythology, to DC Comics. Not only are the aesthetics of these games massively varied, but there are also lots of points of difference in the mechanics.

A slot’s payout rates depend on a variety of factors: the number of ways to win, known as paylines; the Return to Player (RTP) percentages, indicating average payout amounts; and variance ratings, which affect the size and frequency of these payouts. Let’s break these three areas down a bit further.

Paylines

The world’s first slot machines had a very simple payline structure – since there was only one reel in play, players only had access to one payline. When slot machines first migrated into the digital realm, they initially honoured this classical layout, replicating the much-loved fruit machines of the past. 

Slowly, slot developers started to change the scene by increasing the number of reels and the number of routes to success. This in turn increased the number of paylines initially to three, then to five, ten, and so on. Recent innovations in payline technology, such as Big Time Gaming’s highly-rated Megaways structure, has changed online slots forever.

These Megaways titles are available at all the top slot game sites, and offer an astonishing 117,619 ways to win, thanks to the changing number of symbols per reel throughout the game.

RTP

Return to Player rates give online gamblers an idea of how much they can reasonably expect to win from any one game. Expressed as a percentage, the industry average for online slots is around 96%, meaning that players wagering €100 on a slot with this RTP will receive €96 back on average.

Gambling sites should display the RTP percentages of all their games, although for casino games such as roulette, blackjack and poker, they will typically refer to the reverse figure of house edge. For instance, a game with an RTP percentage of 97% has a house edge of 3%.

However, players should always take the RTP percentages of online slots with a pinch of salt. Although these figures provide useful insight into average payout rates, the calculations are derived from machines that simulate millions of spins of the reels. As such, any one gambling session can deviate massively from the script, and returns from a playing session can be far higher or lower than the average.

RTP rates demonstrate the inherent house edge built-in to all casino games. These games have all been designed to ensure the casino makes money, and although players still have the chance to win cash, the more they play, the more likely they are to land on the game’s base RTP rate.

Variance

Of course, if everybody knew exactly how much they stood to win when they spun the reels, online casinos would quickly run out of business. What makes online slots worth playing is their variance, also referred to as volatility. The variance of a game is a reflection of the size and frequency of payouts when they occur.

Variance is typically referred to as low, medium or high – and preferences will come down to a matter of taste as well as budget. 

Slots with high variance are more likely to pay out infrequent but sizable rewards, while low variance slots will offer frequent but small cash prizes. Medium variance games, on the other hand, offer a balance between the two.

Random Number Generators

For years, many gamblers have convinced themselves that it’s possible for a slot to be ‘hot’ or ‘cold’, meaning more or less likely to pay out. Some players avoid games after a jackpot has just been hit as they think it won’t be due to hit again for a long time. However, this is all a myth — and we can be sure of this thanks to the Random Number Generator (RNG).

The RNG runs inside every slot game and uses an algorithm to generate a random number, which then corresponds to the combination of symbols that appear on the reels each spin. There are billions of potential numbers and combinations, ensuring every game is fair and truly random. What’s more, gambling regulators can check the results of each RNG programme to ensure a slot is operating as it should be.
