Our Best Slot Site for Bonuses is SpinsBro Casino

Currently, SpinsBro offers a highroller matched deposit bonus up to €2,000 plus 200 free spins on the slot Sugar Rush. The reason it's called a highroller bonus is because you need to deposit €500 to get the €2,000. 

If SpinsBro's main welcome bonus isn't your cup of Barry's tea, it has a welcome offer for a smaller deposit. You can get a 115% bonus up to €420 on your first deposit of at least €20, plus 100 free spins on the slot Sugar Rush.

  • Need to know: SpinsBro further proves its 'bro' status with a weekly cashback offer of up to 15% as long as you deposit at least €50 the previous week and have made at least two deposits in total before.
  • Our view: it's rare online slots sites offer separate welcome bonuses for highrollers and more casual players, so these SpinsBro offers are impressive. What's more, it's hard to complain at 100 or 200 free spins!
Spinsbro Bonus 490% Welcome Bonus up to €2120 + 1000 Free Spins
18+, New Customers Only, Play Responsibly, T&Cs apply. This promotion is available only to newly registered users of Spinsbro.

Our Best Slot Site for Games Selection is Casumo

Casumo has a bumper slot selection of nearly 2,800 titles and counting. You can enjoy using the 50 free spins from its welcome bonus on Wild Wild Riches, while the first deposit bonus up to €300 could be used on slots from Casumo's catalogue like Rich Wilde and the Book of Dead, Rainbow Riches, and Reactoonz.

  • 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 in safe-guarding bettors and making sure no-one's using your money who shouldn't be!
  • 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.

Our Best Alternative Slot Site is Betway

Betway is one of the best online slots sites in Ireland with about 300 popular slot titles, including progressive jackpots like Immortal Romance: Mega Moolah, and Game of Thrones: Powerstacks, plus famous names like Big Bass Bonanza, Wolf Blaze Megaways, and exclusives like Betway Cash Megaways. It's definitely a case of quality over quantity.

  • 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. Betway also has weekly Casino Rewards with up to 250 bonus spins, a €100 bonus, and a €25 free bet up for grabs, depending on how much you deposit between Monday and Thursday.
  • 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.
Betway Bonus Welcome Package up to €150 + 100 Free Spins

How We Review Slot Games

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. 

The Top 10 Best Slots in 2024

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! 

Slot SiteSlotsAverage Withdrawal Time
iWild 5,00024 hours
Fire Vegas4261-5 days
Snatch5,00024 hours

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.

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.

How We Rate The Best Online Slots Sites in Ireland

At Casinos.com, 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. 

What We Look For

These are typical features the best online slots sites share:

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 to navigate

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.

Works well on mobile and desktop

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. 

Great promotions section

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.

Variety of 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.

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 2: they also test and compare the best online casino bonuses offered by each site.

Step 3: they make deposits using different online casino payment options to catch any banking and security issues. 

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 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.

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.

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
Free spins are a great way to get to know how slot games work and have a look around a new casino.
It’s also a chance to win a big prize.
Disadvantages
Free spins usually come with wagering requirements, which means you must play through the bonus amount a certain number of times before you can withdraw any real money wins.

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 get something for nothing! On slot sites, this usually means rounds of free online slots.
On sports betting sites, you can get a free bet.
Disadvantages
They are super rare.
Usually come with wagering requirements, so you must play through any winnings you claim.

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
The qualifying deposit is usually accessible to all, at €10 or €20.
Like free spins, it’s a great chance to bet on slots for free.
Disadvantages
These bonuses usually have a maximum value, e.g. 10 times the deposit.
Sometimes you must use the real money you deposited before you can bet the bonus money.
