Finding top slot sites in Ireland can be tricky with all the sign-up and deposit steps. But don’t worry – we’re here to help! Our casino experts, who are registered players themselves, note all the features of the sites they love. They then narrow down their list to pick the absolute best. And here they are – our top picks for bonuses, game collections, and more!
SpinsBro Casino: Our Best Slot Site for Bonuses
Currently, SpinsBro offers a high roller matched deposit bonus and free spins on slots like Sugar Rush. The reason it's called a high-roller bonus is because you need to deposit €500 to get the max bonus.
If SpinsBro's main welcome bonus isn't your cup of Barry's tea, it has a welcome offer for a smaller deposit. Deposit at least €20, and you’ll get a match bonus on your first deposit plus free spins on selected slots.
Need to know: SpinsBro often offers weekly cashback. To qualify, you'll usually need to deposit at least €50 the previous week and make two deposits in total.
Our view: It’s pretty rare to see online casinos offering separate welcome bonuses for high rollers and casual players, so SpinsBro’s approach is definitely something to note.
18+, New Customers Only, Play Responsibly, T&Cs apply. This promotion is available only to newly registered users of Spinsbro.
Casumo: Our Go-to Slot Site for Games Selection
Casumo has one of the best online slot collections. We counted over 3,500 titles, and the number is still growing. We were especially impressed by the Megaways and Trending Now sections. But they have all the fan favourites, so go explore and find your next game.
Need to know: Don't be surprised if you're asked to confirm your identity when withdrawing for the first or second time. Ensuring players are who they say they are is an important part of a casino's role.
Our view: with a shedload of the best online slots, a tempting bonus, and even a mobile app, Casumo is cementing its place as one of the best online slots sites in Ireland.
Casumo Bonus
100% Welcome Bonus up to €300 + 50 Free Spins
18+, New Customers Only, Play Responsibly, T&Cs apply. The welcome bonus contains 50 bonus spins on Wild Wild Riches and 100% bonus (up to €300). Bonuses must be wagered 30 times. Min deposit is €20.
Betway: Best Alternative Slot Site
Betway has come a long way since we last checked. Its slot collection has grown from just 400 titles to over 1,700! With exciting games like Immortal Romance and Big Bass Bonanza, there’s plenty to explore. We can’t wait for you to explore more!
Need to know: On top of the slot selection, Betway is well-known for its esports betting, and you can get weekly esports bonuses like a €10 free bet.
Our view: Like alternative music, you might fall in love with Betway, its quality slots, creative bet clubs, and weekly bonuses. Once you see what it has in store, by clicking 'Play Now' and signing up to Betway below, our 'alternative' slots site might become the only one for you.

Bonus Spins awarded on Cash ‘N Riches, 10 000 Wishes, Western Gold 2 and 777 Surge at €0.10 per spin. Bonus Spins are valid for 7 days and subject to wagering of 30x.

What is the Best Online Slot to Play?
The best online slot varies depending on the person. Do you just want the slot with the biggest average payout? Do you want a progressive jackpot slot with the biggest overall prize? Or maybe a slot with a free spins bonus round or one with amazing graphics and a live dealer?
We know every Irish slots player is a little different to the next, so on this page, we try to expose you to some of the very best online slots and explain their pros and cons.
Top 10 Best Slots Right Now
To give you some 'slotspiration', here are some of the hottest video slots right now:
Divine Fortune from NetEnt
Divine Fortune is an aptly-named online slot with a fantasy theme and a progressive jackpot. It features characters famous in Greek legend like the flying horse, Pegasus, Medusa, the serpentine femme fatale, and the Nemean lion. It's a medium volatility slot with a good return to player percentage (RTP) of 96.59%.
Gonzo’s Quest from NetEnt
Gonzo, the Spanish explorer seeking the golden riches promised in the legend of El Dorado, has earned cult status in the world of slots. Gonzo’s Quest, released way back in 2011, is another NetEnt game that’s cemented the software developer’s status as one of the best in the slots business. The slot has an avalanche multiplier feature that keeps the excitement flowing and a free spins bonus round. And now, you can play Gonzo’s Quest Megaways.
Starburst from NetEnt
Starburst is deceptively simple but that’s its genius. Playing Starburst, you can feel the nostalgic buzz of slot machines, with lucky seven and jewel symbols, complemented by fantastic sound design, wilds and win both ways paylines.
Mega Fortune from NetEnt
Mega Fortune’s charm comes more from its massive progressive jackpots than its design, although it does have a free spins round, with 10 free spins and a 5x multiplier. A player from Finland won almost €20 million on Mega Fortune in 2013.
Mega Moolah from Microgaming
Like other slots with ‘mega’ in the title, Mega Moolah occasionally dishes out some big jackpots, so it’s worth a try for this reason alone. A Belgian player won €22 million on the slot in 2021. Quite the jackpot!
Mega Joker from NetEnt
You could be laughing your way to the bank if you win on the variable Mega Joker jackpot. The slot’s based on traditional fruit machines and offers a high 99% RTP percentage. The jackpot tends to max out at about €1.5 million, and the game’s highly volatile, so payouts are spaced out.
Snakes and Ladders Live from Pragmatic Play
This live casino slot from Pragmatic Play, with a 96.30% RTP, features a bonus round on a snakes and ladders board and is hosted by a real-life dealer. You can bet between €0.01 and €4,500 so it’s suitable for all budgets.
Wolf Gold from Pragmatic Play
This 96% RTP slot by Pragmatic Play is like a spiritual journey into the American desert. It’s popular with slot fans despite seeming ordinary on the surface. The sound effects of wolves howling and eagles calling set the tone, which is only broken by the sound of winning.
Immortal Romance from Microgaming
Part of Immortal Romance’s popularity comes from its 98% RTP and 25 paylines – online casino fans love slots that give a better chance of regular wins. Like other NetEnt slots, it has a fun theme, this time featuring vampires and their prey.
Reactoonz from Play'n GO
From Play’n GO, another top software provider, Reactoonz has a kind of Men in Black meets Pixar vibe that grabs your attention. It has a 96.51% RTP and a 7 by 7 grid. You can win 4,570 times your bet on this out-of-this-world slot.
18+, New Customers Only, Play Responsibly, T&Cs apply. The welcome bonus contains 50 bonus spins on Wild Wild Riches and 100% bonus (up to €300). Bonuses must be wagered 30 times. Min deposit is €20.
The Biggest Ever Wins on Online Slots
If you bet on slots, the holy grail is probably winning on a progressive jackpot slot. For inspiration, take a look below at the biggest ever jackpot slot wins:
€22.14 million: Mega Moolah: Absolootly Mad was the slot to thank for one lucky Belgian player as it gave them a suitably crazy win in 2021. This is the largest recorded jackpot win on an online slot.
€22.03 million: a British bettor, playing at Grand Mondial Casino, won the top prize on the original Mega Moolah progressive jackpot slot.
€19.7 million: way back in 2013, a slots fan from Finland won a huge jackpot on Mega Fortune which would last as a record win for two years. The punter bet only €0.20, showing mighty oak trees can grow from small acorns.
€18.65 million: a usual suspect — Mega Moolah — changed another life when British war veteran Jon Heywood, 26, bet a measly €0.25 and won a whole lot more from one spin in 2015.
€16.20 million: Arabian Nights is a quirky, somewhat dated slot, but winning €16 million will never go out of fashion. That’s the jackpot a player from Norway won on the game in 2011.
Irish Slots Online to Avoid
If you’re hoping to pick up regular wins, you should avoid playing progressive jackpots and other slots with high volatility, because they pay out quite rarely on average.
This could even include famous slots like Mega Moolah, which is included in our ‘Top 10 Best Slots in Ireland’ list. Although you could win €20 million with a €1 bet, the odds of winning on a jackpot slot could be as bad as one in 34 million.
Plus, always pay attention to the RTP of a slot, as it’s a good indication of how much, on average, you can expect to win from your bets.
Online Slots Payouts: RTP and Volatility
For those of you just looking for the best chance of winning, these high-RTP slots online could be a great starting point:
From the list, Book of 99 has an RTP of 99%, meaning, on average, it gives €99 back for every €100 bet, which is very high. It’s also highly volatile though, so, while it does give out big wins sometimes, it doesn’t happen too often.
In contrast, Jack Hammer 2 also has a relatively high RTP of 97.07% but it has low volatility, which means, on average, you can expect to win more frequently but the wins will probably be smaller.
Our Slot Sites Review Process
With this in mind, we try to keep our slot site review process the same every time for fairness and consistency. This is how our reviewers rate a slot site:
Step 1: our expert opens an account at the site we want to review and judges how smooth the sign-up process is.
Step 4: they then play slots on the site to get a feel for their payout rates, multiplier features, bonus rounds, graphics and user experience.
Step 5: they also withdraw their funds to test how quick and easy the process is and if there are any problems.
Step 6: finally, the expert highlights any special features the slot site has. For example, Mason Slots has a unique site design and gives depositing players ‘secret free spins’ on Mondays.
How We Rate The Best Online Slots Sites in Ireland
At akfxoqsd.shop, we have a cracking team of casino experts who review slot sites so we can share the best with you, and we’ll be sure to tell you if there’s any you shouldn’t touch with a barge pole!
With our years of experience in online casinos, we can usually tell straight away if a site is one of the good guys or if it should go on the ‘not worth your money’ pile. We inspect everything a site's got to offer, from withdrawal speeds and customer support to the diversity of games in the lobby. We love to see everything from classic online baccarat and poker to the latest live titles, but we know it's slots that really have casino players coming back time and time again.
These are typical features that we look for in an online casino:
Lots of Online Slots
Although we believe in quality over quantity, most of the best Irish slots sites offer at least 1,000 games, and we see this as a bright green flag. It’s true that some sites flatter to deceive, with a huge range of games, but none that capture the imagination, but usually, the more slots available, the more chance of finding a game that you’ll love.
Easy Navigation
It’s not usually something the best slots sites brag about but when it’s easy to get from the home page to the promotions section, or to find a specific slot title among a sea of them, it makes betting on slots way more fun, so these sites tend to get a thumbs up from us.
Mobile Friendliness
In 2024, most slots players bet via their mobile but we know many of you still bet from your desktop, so it’s key that sites perform well on both. The best slots sites probably have real money casino apps too and we look favourably on this.
Promotional Offers
Apart from the thrill of winning on online casino slots, slot promotions are probably the punter’s favourite feature. The better the site has and the wider the variety, the higher we’ll rate them in this area. Some of the best Irish slots sites, such as Neon54, even have several welcome bonuses to choose from.
Slot Types
As well as having the big-name casino online slots, we expect slots sites to feature the whole spectrum of game types, from classic 3 by 5 fruit machines to 3D live casino slots, with live dealers. New slots with presenters, including Gonzo's Quest Live, give you the best of both worlds: the fun of slots plus the extra immersion from a real life dealer that you'd get at the best online blackjack sites.
Inclusive Bet Limits
Unless the slot site’s made for a specific audience of bettors on a budget or high rollers, we like to see sites offer low minimum and high maximum bets.
How Slots Work: The Basics
If you haven’t bet on slots before, here are the basics on how to play:
Every online slot comes with a minimum and maximum bet amount
Every game has its own return to player percentage, between 1 and 100, with a higher number meaning the game pays out more over time on average. Some players agree an RTP over 95% is pretty good, but it all depends on personal preference.
Like fruit machines at physical casinos, each slot online has symbols, with each carrying a multiplier value, eg x2, x3, x4, x5 and x10, from the most common to the rarest. If you spin several of the same symbol on a payline, then your win is multiplied by the corresponding value of the relevant symbol. And, the more of one symbol you land, the bigger the prize. For example, if you bet €1 and spin 3 diamond symbols in a row, you might win an extra €0.10 but if you spin 5 diamonds, you could get an extra €2.00.
The best slots also have a bonus round, which gives you the chance to supersize your win. This usually consists of about 10 free spins.
You can aim for big slot jackpots on the games below:

Types of Real Money Online Slots
It takes all sorts to make real money slots as compelling as they are. There’s classic slots, progressive jackpot slots, Megaways, and branded slots.
Progressive Jackpot Slots
These are the big daddies or mammies of the online slots world. Progressive jackpot slots are the ones that get all the headlines with multi-million-euro wins. Winning a slot jackpot is like winning the lottery. It’s also virtually as unlikely you’ll win one.
The beauty of these slots is every time a player bets and loses, the jackpot gets bigger, until someone – hopefully you – eventually takes the main prize away. There’s no guarantee you’ll win a record amount – although Mega Moolah has a minimum win of €2 million – it depends how long it’s been brewing.
Megaways Slots
Big Time Gaming created Megaways slots, which are games with up to 117,649 paylines, far higher than the modest 10 paylines featured in the famous Starburst slot. It’s possible to offer this many different ways to win because the paylines change after every spin. Although there are lots of ways to win, this doesn’t make your chances of winning higher. For example, Max Megaways 2 has a good but not the best RTP of 96.64%.
Classic Slots
These traditional slots are usually built on three-reel by five-row grids and follow the themes of fruit machines or slot machines you find in land-based casinos. They’re still popular partly because they have an authentic aura and evoke the atmosphere and excitement of the original slot machines, with fruit and jewel symbols and five paylines. If you think the old games are always the best, you’ll probably enjoy classic slots like Mega Joker, Mystery Joker and Jackpot 6000.
Branded Slots
Lots of famous bands, TV shows and movie stars have a slot named after them. These are called branded slots and some examples include Jumanji, Hell’s Kitchen, and Guns n’ Roses by software provider NetEnt, Monopoly Megaways by Big Time Gaming, and Popeye from Lady Luck Games.
Online Slots Bonuses and Free Spins in Ireland
As slots are so popular with bettors and online casinos, it makes sense that the most common bonus type involves online slots with a sign up bonus. If you make a qualifying deposit, a welcome bonus could get you free spins to play online slots, and from time to time, there’s even a no deposit bonus at some of the best Irish slot sites.
Free Spins Pros and Cons
Free spins are a common online bonus for slots. Bonus spins are simply free rounds on slot games, that can range from just one to hundreds, and sometimes they come in one go and other times, you’ll get a certain amount each day until they’re used up.
What’s more, the slot site will usually select and exclude certain games for use with the free spins – for example, progressive jackpot slots, which might offer a bigger maximum prize, are often excluded.
Free spins are usually given out when you sign up and make a first deposit at some of the best Irish slots sites. You can even get them on several of your first few deposits, which seems to be more common these days. For instance, at CasinoMega, you can get a matched deposit bonus, a non-sticky bonus, and free spins over your first two deposits.
And if welcome bonus free spins are too few and far between, some sites like SpinYoo Casino, offer five daily free spins when you deposit €5. You can claim 25 free spins each day.
Advantages
Great for learning how a slot game works
Ideal for looking around a new casino
A chance to win a big prize
Disadvantages
Usually come with wagering requirements
No Deposit Bonus Pros and Cons
An online slots no deposit bonus is almost as rare as hens’ teeth, after slot sites realised they couldn’t keep up with the demand for them. No deposit bonuses are used to attract you to sign up to a casino in the hope you’ll go on to be a regularly-depositing customer.
However, when a casino offers this bonus with no deposit or wagering requirements, the casino loses money, and some players will take the money and run.
888casino, one of the best slots sites in Ireland, is one of the few that still offers a no deposit bonus on free online slots. It currently gives you 88 free spins just for signing up but you have to wager your winnings one time.
Advantages
You might get free stuff, like rounds of free slots
On sports betting sites, you can get a free bet
Disadvantages
They are super rare
There are often wagering requirements involved
Matched Deposit Bonus Pros and Cons
This kind of deposit bonus usually comes with a welcome offer, although sites do periodically offer it in promotions to existing players. When joining a site, you’ll get a certain percentage of your first deposit back as bonus cash, which needs to be wagered before you can withdraw your winnings.
Advantages
Budget-frienldy qualifying deposits of €10 to €20
An opportunity to try a popular slot with free/bonus spins
Disadvantages
Often have maximum value limits
Wagering requirements are part of the deal
