Best Irish Online Slot Sites - 2023

How We Choose the Best Irish Slots 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 ‘2023’ 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.

Bonus Terms and Conditions

Bonuses can give your online casino experience some real oomph, and we want to make sure our visitors enjoy the best bonuses on the market. We dig deep into the small print of slot offers to uncover bonus restrictions like wagering requirements, winning caps and expiry times to find the most player-friendly bonuses around. 

Payment Options

We think it should be easy to deposit and cash out winnings at an Irish slots site, so our reviews always include a roundup of what’s available on the cashier page. We expect the best sites to offer a range of options, including debit cards, Trustly, Paysafecard and e-wallets like PayPal and Neteller. Fast payout times earn slots sites extra kudos. 

Site Design and UX

It perhaps goes without saying that the best Irish slots site should be well designed and provide a great experience to players. We evaluate what slot sites offer in this regard, checking out their desktop and mobile platforms to make sure they tick all the right boxes. Fresh themes, intuitive navigation options and fast loading times are characteristics of the best-performing sites in this section. 

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 several categories of slot games you can play. Here’s are some different types of Irish slots you might find:

Classic Slots

Classic slots are the nostalgic pub slot games that have made their way onto the online slots scene. 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. Despite the progression in the Irish slots market, classic slots are still a firm favourite. 

Many of the top software developers have spruced up the best retro games to suit the modern player. As an example, check out Play’n GO’s Lucky Diamonds classic slot which sits amidst a slots library of more than 280 titles. Or perhaps Red Tiger Gaming’s Laser Fruit, which sticks to the classic style but includes features such as blue lasers, Megaways, and free spins. 

Video Slots

Video slots offer a more themed style of game than the classic slots and include great animations, in-play bonuses, and some rather cool sound and visual effects. Some examples of these games include Microgaming’s Rainbow Riches, NetEnt’s Starburst, and Deal or no Deal, plus hundreds of others. This type of Irish casino slot also offers the largest number of reels on the best slots sites, and the paylines are generally the largest of the four categories. 

Nowadays, it’s video slots that dominate a games library. With the freedom to be creative, it’s the easiest area for developers to show off their skills and create unique titles. It’s also the area in which you’ll find the most exciting features, such as wilds, bonus rounds, scatters, cascading reels, and much more. 

Progressive Slots

Progressive casino slots games are a great way to hunt for big jackpot wins. Each time a player makes a spin on a progressive game, the total jackpot increases until it is won. There have been many newsworthy progressive slots wins that reached high into the millions, most notably with Microgaming’s Mega Moolah which has produced winnings as high as $20m. However, this type of game is extremely high in variance and offers an RTP of a pretty low 88%. What this means is that the payout rate may be large when it arrives, but it pays out quite rarely.

Megaways Slots

Originally created by Big Time Gaming, Megaways is a mechanic that randomly modifies the reel of a slot game by changing the available symbols. But what is the benefit of this? With a Megaways slot, because of the change of symbols, the chances of winning are drastically increased, sometimes by thousands of times compared to traditional slots games. It can also add an exciting dimension to the game, especially when combined with other popular features such as multipliers and bonus round games. As an example, Temple Tumble was Relax Gaming’s first slot game to use the Megaways feature. It’s a popular title that offers 46,656 ways to win, holds an RTP of 96.2%, and is full of unique features and bonus rounds. 

Cluster Pays Slots

Cluster pays are unique slots games where you achieve winning combinations from clusters of the same, or matching symbols forming on the reel. Typically with slots games, it is a payline that must be completed, however, in this case, a win is achieved if the symbols gather in cluster formations. Many people enjoy cluster pay slots because of the unpredictability they offer – that element of not knowing where a cluster will form. In addition, there’s a higher chance of winning thanks to the formations required – not needing to complete a particular payline means more opportunities to win. If you fancy trying one out at the best Irish slots, Aloha! Cluster Pays by NetEnt is one of the most popular games around – it provides six reels and five rows, many opportunities for free spins rounds, and unique features such as the symbol drop. 

Slingo

Invented in the mid-90s, Slingo is a mashup of slots and bingo. The basic principle of the game sees players starting with an empty bingo grid that they fill with numbers through spins instead of by numbers being called out randomly through RNG technology. It’s a great individual or multiplayer game that’s available at the majority of the best Irish slots sites. As with most game types available to play online, Slingo comes in a wide variety of themes. One of the most popular is Slingo Rainbow Riches which offers 12 paylines, five reels and some unique bonus rounds like Magic Toadstool and Pots of Gold.

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 Irish Slots to Play in 2023

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.

Lucky Leprechaun

This Microgaming creation is packed full of features such as free spins rounds and instant win opportunities. It offers an RTP of 96.33% and a medium volatility. Lucky Leprechaun is vibrantly coloured, and full of symbols and icons that people associate with lucky Irish charms – think pots of gold, violins, and green or gold clovers. Unsurprisingly, a lucky leprechaun stands as the wild symbol, replacing everything on the payline except a pot of gold or the shamrock. 

9 Pots of Gold

Another of Microgaming’s creations, 9 Pots of Gold, is an Irish themed video slot that was released in 2020. There are some great features to this game, including a scatter that triggers not only a free spins round but the chance for an instant win of up to 2,000x your stake. It’s played across five reels and 20 paylines, and as you can imagine from the theme, follows a tale of Irish folklore, with regular symbols represented as objects such as leprechaun hats, four leaf clovers, and golden harps. A mushroom acts as the wilds symbol and this substitutes every symbol on the paylines except for the pot symbols and free spins. If you hit between three and five wilds on one of your paylines then you will be rewarded with up to 125 times your stake. 

Sweet Bonanza

Launched in 2019, the theme for this Pragmatic Play video slots title is all things associated with our classically favourite sweets. It sits on six reels and an all ways win payline display and carries an impressive maximum win limit of more than 21,100x. As expected from the theme, it’s bright, colourful and cartoon-like in appearance, with all the symbols being various types of sweets. There are some great features to this slots game, including a random multiplier that provides up to 100x free spins and to win, all that is required is eight or more of the same symbol anywhere on the reel.

Because of its popularity, a subsequent follow up version called Sweet Bonanza Xmas is also available. This mirrors the theme of Sweet Bonanza except with a more Christmassy, festive feel to the background.

Fluffy Favourites

Fluffy Favourites has seen a rebrand from the original version that was brought out back in 2006 by Eyecon. Due to the popularity of the theme, it is now available in a range of formats, including as a megaways and mix’n win slots game. Fluffy Favourites is a bright and colourful game, with animal characters such as cartoon lions, rhinos and dragons denoting the symbols. It houses 25 paylines, and five reels to play across. There are some great bonuses available, like the toybox pick up bonus that is triggered following a spin of three or more scattered claws across the reel.  The elephant symbol is one of the most important, and can replace everything except scatters. Land enough elephants and your prizes can be doubled. 

Bronco Spirits

Pragmatic Play’s Bronco Spirits is a five reel, 75 payline slots game that is themed on Native America. It offers a 2,000x maximum payout. Players need to collect gold bronco coins to win Wild symbols that are available with every ten spins and sit among other symbols on the reel like campfires, headdresses, and tomahawks. Bronco Spirits is a simple game in terms of rules, so it’s great for those who just want to play a slots game without having to know a great deal about it beforehand. There are some good features, particularly with regards to free spins. For example, if you land three or more bonus symbols then you will trigger the free spins round, with the amount of free spins being dependent on the bonuses you achieved. There is also a limitless amount of retriggers once in the free spins bonus. 

Slot Features and Mechanics

Slot features and mechanics are designed to make spinning the reels even more fun and potentially more profitable too. You can find fun slots features on classic slots and new games alike, though it’s fair to say that modern slots have the edge when it comes to these exciting extra perks. Let’s check out some of the unique features that developers add to online slots to make them stand out from the crowd.

Wilds

Wilds are probably the most common feature you’ll come across when you play slots online. They can appear as simple symbols or as the main character of the game, such as in the Cleopatra online slot. In basic slots, wilds substitute for other paying symbols to help form winning combos. However, some more feature-rich slot games offer exciting variations like expanding wilds and sticky wilds. 

Scatters

Scatters usually work by triggering a bonus feature, such as a mini game or a free spins round. You might also come across a scatter pays feature, which does away with a bonus feature in favour of offering an immediate payout. To unlock the perks of scatter symbols, you’ll typically need to land three or more of these symbols, sometimes on specific reels. Landing more may unlock bigger and better rewards. 

Free Spins Round

A free spins round is a feature often triggered by landing three or more scatters. Sometimes taking place on a separate set of reels, you’ll usually get between five and 20 free spins to start. In some free spins rounds, you can re-trigger the feature, sometimes an unlimited number of times, such as in Cat Wilde and the Doom of Dead. In others, you might enjoy extra win potential in the form of multipliers and respins. 

Avalanche Reels

Instead of spinning, avalanche reels tumble down the screen. When a winning combo is formed, the paying symbols explode and more tumble into place, potentially adding more win lines. Avalanche reels were first seen in NetEnt’s Gonzo’s Quest, where each avalanche also increases the win multiplier by one. Other developers have been quick to launch their own versions, with Slingo Originals’ Slingo Cascade one popular example. 

Expanding Reels

Expanding reels work by expanding the layout of slot machine games, in turn providing players with more opportunities to land winning combinations. An example of expanding slot reels can be seen in Nolimit City’s edgy Punk Rocker slot, where collecting three or more bonus symbols unlocks a sixth reel, sets loose up to four jumping wilds and increases the number of paylines from 243 to 46,656. 

Multipliers

Multipliers in online slot games work by multiplying bets, line wins and total wins, usually up to 10x but sometimes up to 1,000x, 2,000x or more. Multipliers can be triggered in a variety of different ways, including by wilds and scatter symbols, as well as in free spins rounds and bonus games. In the Bonanza Megaways slot, the multiplier increases by one every time you land a winning combo courtesy of its cascading reels. 

Cluster Pays

Another innovation by NetEnt and first seen in its Aloha slot, cluster pays adopts a unique approach to winning combos. In cluster pay slots, matching symbols must land in a cluster with each symbol touching on at least one side. The minimum number of symbols is usually five, but the more you get, the bigger the payout. As with other popular features, other developers have launched their own take.  Roxor Gaming’s Secrets of the Phoenix Elements is a good one to try.

Other Games to Try at Irish Slots Sites

Many of the best online casinos and slots sites offer online and live dealer casino games — and sometimes sports betting too — alongside their selection of slot games. Let’s see what you might find on the menu.

Blackjack

This classic game takes centre stage among card games at online casinos for Irish players, and you’ll find many exciting variants complementing classic games like Microgaming’s Classic Blackjack Gold. We especially like Cashback Blackjack. This online blackjack game from Playtech offers odds of up to 100-to-1 on the 21+3 side bet. And, in a twist inspired by Deal or No Deal, you can also choose to hit the cashback button, end your hand early, and bag a prize. Don’t like the offer? Simply play on to see if you can win more. 

Roulette

Like blackjack, roulette comes in a huge variety of styles at online slots sites and casinos. Expect to find classic European, French, and American roulette games sitting alongside titles like Speed Roulette and 3D Roulette. We also suggest looking out for Golden Rock Studios’ Roulette x5. Here, a dice roll that follows each call gives you a boost of up to 500% on your winnings. There are also plenty of themed roulette games you can try, such as Pinball Roulette, plus exclusive online roulette games like BetVictor’s Blue and Black Roulette. 

Baccarat

One of the oldest and most glamourous of casino games, baccarat makes an appearance at most online casinos and slots sites. Sometimes referred to as Punto Banco, baccarat is a pretty simple game, requiring you to do little more than predict if the banker or player hand will be closest to 9. However, that doesn’t stop developers adding a few twists and turns to the tale. The best Irish online casinos sit classic baccarat games alongside must-try variations like Speed Baccarat and No Commission Baccarat. 

Video Poker

There’s no doubt that poker is one of the most popular games on the planet, so it’s little wonder that many online casinos add a few video poker titles into their mix of games. Video poker games like Joker Poker and Jacks or Better are often referred to as poker slots, but don’t be fooled. Unlike slots, the outcome of video poker games relies on a mix of skill, strategy, and chance — rather than luck alone. Microgaming’s Deuces Wild, where 2s are wild, is one of the highest paying video poker games, and a game worth mastering. 

Live Dealer Games

If an online slots site offers table games, there’s a decent chance it gives players the chance to play live casino games too. You can find live dealer options for classic casino games like blackjack, baccarat, and roulette, and many sites will also offer live dealer poker games like Evolution’s Casino Hold’em and Caribbean Stud Poker. You can also try your luck in the hot seat of upbeat live dealer casino game shows like Crazy Time, also from Evolution, and Sweet Bonanza Candy Land from Pragmatic Play. 

Sports Betting

Many of the top online casinos in Ireland pop real money sports betting under the same roof as online slots and casino games. From Aussie Rules to American Football, these sportsbooks usually offer betting markets on sporting events from around the world. And, of course, the Emerald Isle serves up plenty of homegrown action too. You’ll find horse racing at the likes of Curragh and Leopardstown Racecourses and golf at Old Head Golf Links and Palmer Course among the many ways to wager at Irish online casinos. 

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

Debit cards are the most widely used payment method at online casinos and are accepted at almost every Irish slot site. As deposit methods go, debit cards have a pretty long list of advantages, not least that they allow you to make instant, fee-free top ups to popular sites like Casumo and Mr Green and will prove eligible for most slot bonuses. In short, if you want a steady, reliable and familiar option, then this is where to start. 

Debit cards may not always be the best choice if you want fast withdrawals though. Standard payouts to Visa and Mastercard usually take between three and five days, and sometimes more. This makes it worth considering sites that offer the Visa Fast Funds service. At these sites, you can expect payouts to Visa debit cards to land within 30 minutes of site approval. 

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 instantly. PayPal, Skrill and Neteller lead the way and are all available at many sites, and newer e-wallets like AstroPay, ecoPayz, and MuchBetter are starting to gain a foothold too. 

e-Wallets allow you to deposit at online casinos and slots sites using only your email address, so they make a good pick for security-conscious casino players who don’t want to share bank account or debit card details with a gambling site. However, e-wallets don’t always qualify for promos, so it pays to check the terms and conditions of any bonus offer before making your qualifying deposit and starting to play casino games and slots online.

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. Paysafecard vouchers are available in a range of different denominations, though subsequent deposit and payment limits can be on the low side unless you sign up for a Paysafecard account. Prepaid cards rarely 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. Many slot sites will offer a payout via bank transfer to players finding themselves in this position. Bonus eligibility can also be a bit hit and miss with prepaid options like Paysafecard, and you may need to choose another deposit option to qualify for promos.

Pay by Mobile

Pay by mobile refers to a range of services that allow you to use your mobile phone number to pay for your deposits. At the point of transaction, key in your number, and your mobile network provider will pay for your deposit on your behalf before charging it to your PAYG balance or your next monthly bill. Boku is the leader in the pay by phone space, but there are a few other companies that offer this service — including Payforit, Zimpler, and Siru. 

Pay by mobile deposits don’t always qualify for slots site bonuses and promotions, nor do these carrier billing services pull double duty to facilitate withdrawals. There are also strict limits on how much you can deposit using pay by SMS services, both for individual transactions and over the course of each month. 

Trustly

Using Open Banking technology, Trustly allows you to deposit at Irish slots sites directly from your bank account. You won’t need to open an account, pay any fees or share financial details with Trustly or the slots site. Just select Trustly on the cashier page and log into your bank securely to confirm your deposit amount.  With deposits landing instantly, that’s all there is to it.  

Aside from the ability to make instant, secure deposits direct from a bank account, Trustly has plenty of other benefits as a payment option. High limits, excellent eligibility for bonus offers and fast payouts all make Trustly a top pick among players. 

AstroPay

AstroPay comprises a trio of online payment options, including the AstroPay digital wallet, the original AstroPay virtual prepaid card and the AstroPay prepaid Visa card. The sheer range of payment options available from AstroPay makes the service attractive to a wide range of players, though it is the prepaid Visa card that has proved something of a game changer.

Historically, AstroPay has been available at a limited but growing number of casinos, with bonus eligibility and payout options varying between sites. The introduction of the prepaid Visa card means that players can use AstroPay like a regular bank card to qualify for more bonuses.

Cryptocurrencies

Casinos and slots sites that accept digital currencies like Bitcoin and Litecoin have grown in popularity in recent years. Probably for good reason. Cryptocurrencies have plenty to offer real money gamblers, not least speed, security and a good degree of privacy. For players who know what they’re doing, crypto can be an attractive banking option. 

Bonus offers at crypto casinos can be particularly rewarding and are another reason why these currencies are so popular with players. However, despite these advantages, it pays to be cautious when dealing with crypto online and always to ensure you’re playing at licensed sites.

Top Software Developers at Irish Slots 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.

Nolimit City

A relative youngster in the scene, Nolimit City was formed in Sweden in 2014 and focuses its energy entirely on creating a detailed and varied range of slots titles for its gaming catalogue. Its games can be quite serious in theme, such as Serial which is about a killer on the loose, and Book of Shadows which is based on an enchanted altered reality. In terms of design, its slots often take on a hand-drawn cartoon appearance, with incredible graphics and just as exciting features alongside. For example, xSplit Wild which can split up scatter symbols and xWays symbols that can transfer normal payout symbols. As a brand, Nolimit City is unique, bold, and certainly a name to look out for among the best Irish slots.     

Yggdrasil

Founded in 2013, Yggdrasil has since launched a range of popular titles that particularly focus on video slots titles and are available at the best Irish slots sites. Some of these include Double Dragons, Valley of the Gods, and Nirvana. The brand may be one of the youngest of the major software developers, but it has already won numerous awards for its work, such as Casino Provider of the Year 2022 and Slot Provider of the Year 202 at the International Gaming Awards. Yggdrasil is ‘the world tree’ in Norse mythology, symbolising the cycle of life, death, and rebirth. This brave choice of name represents the brand’s approach to creativity, and highlights the team’s ambition to reach the top of the iGaming industry.

New Irish Slots 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. 

Best New Irish Slot Games

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.

Octobeer Fortunes

This Pragmatic Play slot is, as you can imagine, based around the world’s largest beer festival, Oktoberfest! Offering an RTP of 96.53% and a high variance, Octobeer Fortunes plays across 5×3 reels. Money symbols on any of the reels can trigger an instant cash prize, there’s also the chance of reaching free spins rounds with the appearance of five or more money symbols across any reel. There are plenty of features to enjoy with Octobeer Fortunes, including scatters, bonus rounds, and a maximum win of 4,500x.

Bee Hive Bonanza

Playing on a five reel and five row scatter pay grid, this NetEnt slots title theme is that of a hive of hard working bees who collect gold coins around their mediaeval bee kingdom. It’s a colourful and creative slot game with some great features including multipliers, avalanches, bonus rounds and prizes that you can win through collecting beehive collector symbols. The game is simple to understand, so perfect for those who just want to enjoy a fun and light-hearted slots game that offers a chance to win up to 5,000x your stake.

Wild Link Zeus

Launched in September 2022, this SpinPlay creation sits on a 5×3 grid with 20 paylines available. The aim of Wild Link Zeus is to land the Wilds symbols which can trigger prizes, extra paylines, jackpot rounds and also offers the chance of an expanding grid that can increase your chance of winning by up to 3 times. If you’re a fan of the sibling slots title, Amazing Link Zeus, that was released in 2021, then this may be the next title for you to try out.

Mobile Irish Slots Sites

We always recommend casinos that have excellent mobile capabilities, including the availability of first-rate mobile apps on both Android and iOS operating systems. No one wants to be tied to a desktop when there are so many other things to do so mobile slot sites offer a convenience of being accessible wherever you may be. With mobile being the preference over desktop for many people, the best Irish slots are devised with this in mind, meaning a better functionality, clearer layouts and games that fit perfectly to a mobile-size screen. 

Let’s take a look at the pros and cons of playing at mobile Irish slots sites.

Casino Bonuses for Irish 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.
