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. They want to test the 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 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. 

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. They have many games, but none are imaginative. Usually, the more slots available, the better the chance of finding a game you love. 

Easy Navigation

The best slots sites don't usually brag about it. But, if it's easy to get from the home page to the promotions section, or to find a specific slot title among many, it makes betting on slots more fun. So, we tend to give these sites a thumbs up.

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 all game types. These include classic 3 by 5 fruit machines and 3D live casino slots with live dealers. New slots with presenters, like Gonzo's Quest Live, give you the best of both worlds. They combine the fun of slots with the immersion of a live dealer, like at the best online blackjack sites.

Inclusive Bet Limits

Unless a slot site targets a specific audience, we prefer low minimum and high maximum bets. This is unless it's for budget bettors or high rollers.

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: In 2013, a Finnish slots fan won a huge jackpot on Mega Fortune. It was 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. In 2015, British war veteran Jon Heywood, 26, bet €0.25 and won big from one spin. 
• €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

To win often, avoid progressive jackpots and other high-volatility slots. They rarely pay out. 

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 has a high RTP of 97.07%. It has low volatility, so you can expect to win more often. But, the wins will likely be smaller.

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 online slot has symbols. Each has a multiplier value, e.g., x2, x3, x4, x5, or x10, from most common to 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 diamonds, 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 Ireland

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. 

These slots are beautiful. Every time a player bets and loses, the jackpot grows. It keeps going until someone – hopefully you – wins it. 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. They have up to 117,649 paylines, far more than the 10 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 3-reel by 5-row grids. They follow the themes of fruit or slot machines in land-based casinos. They remain popular for their authentic aura. They evoke the 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. Examples include Jumanji, Hell’s Kitchen, and Guns n’ Roses by 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. A welcome bonus could get you free spins to play online slots if you make a qualifying deposit. Sometimes, the best Irish slot sites even have a no deposit bonus.

Free Spins

Free spins are a common online bonus for slots. Bonus spins are free rounds on slot games. They can be from one to hundreds. Sometimes, you get them all at once. Other times, you get a set amount each day until they're used up.

Also, the slot site will usually select and exclude certain games for the free spins. For example, progressive jackpot slots, which may have a bigger 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.

No Deposit Bonus

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 a no-deposit, no wagering bonus, it loses money. 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.

Matched Deposit Bonus 

This kind of deposit bonus usually comes with a welcome offer. However, sites do occasionally offer it in promotions to existing players. After joining a site, you'll get a bonus. It's a percentage of your first deposit. You must wager it before you can withdraw your winnings. 

Mobile Slots Sites in Ireland

You can now enjoy your favourite mobile slots in the palm of your hand, on virtually all handheld devices, such as iPhones, iPads, and Android mobiles. In fact, playing online slots on a mobile casino is now more popular than on desktop. All you need is your device and an internet connection!

Now, why not sign up and claim a slot promotion at one of the top online casinos in our exclusive list at the top of the page? You could get bonus cash, bonus spins or extra spins at casinos like Novibet, ZipCasino, and Flappy, or choose another interesting sign up bonus.
