This article explains how we rate the best Irish online slots sites, the types of online slots you can enjoy and how the bonuses work. We also highlight exciting new online slots, the best mobile slots and the leading software providers. Slots are the most popular casino games, so it is pretty obvious why slots are one of our primary interests.
If online slots are your primary goal when joining a new casino, the operators below have by far the greatest slot game selections brought to you by premium slot developers.
Types of Online Slots
While the sites matter and we are here to help you make sure that you've chosen the most suitable slot site for you, the games also matter, so we want to say a few words about slot games and types of online slots in general.
The online slots sector has grown increasingly sophisticated in recent years. Players now have a thrilling array of different slot games to choose from, and many of them have fun themes. Here are the five key categories.
Video slots
These are the original online slots games and they continue to dominate the online slots industry.
Video slots online include the classic 3-reel and the more elaborate 5-reel slots, which can contain exciting features like wilds and scatter symbols, with live-action backgrounds and animations to keep you entertained.
The best video slots online right now include:
- Kingdoms Rise: Captain’s Treasure | A 6 reel, 50 payline slot from Playtech, you must follow the golden compass to win prizes. It has an RTP of 96.05%.
- Wheel of Fortune | Based on the popular TV game show, this slot has 5 reels and 5 paylines. There are 720 ways to win and an RTP of 96%.
- Starburst | A hugely popular slot online, Starburst is great for beginners and veterans alike. It has a generous 96.08% RTP and makes for a fun gaming experience. This is one of NetEnt's most popular slots.
- Thunderstruck II | One of the most popular Microgaming slots, Thunderstruck II has been around for over a decade, but it is still played and revered by thousands of players. The game has 5 reels and 243 ways to win.
- Milkshake XXXtreme | This NetEnt slot has been released on the 23rd of February and it immediately became one of the most sought after games in 2023. The game has a low to medium variance and you can win a maximum of 7,100 times what you have wagered. NetEnt then decided to release another game as part of the same series - Taco Fury XXXtreme which is scheduled to be published on the 9th of May.
3D Slots
Online slots have been given another exciting dimension with the advent of 3D slots, which are becoming more and more popular.
The play is exactly the same as video slots, but the graphics have been given an update, there is a stronger narrative and the overall experience is more immersive.
Top 3D slots of 2023 include:
- The Rift | A slot with a dark magic theme, The Rift boasts 5 reels, 17 paylines and an RTP of 96.3%.
- Turning Totems | A game inspired by Mayan culture and the totems they created. It has 5 reels and 11 paylines, with an RFP of 96.1%.
- Gonzo’s Quest | One of the most popular and iconic games out there, and for good reason, despite the fact that it was launched way back in 2011. Gonzo’s Quest has a fun story and all manner of features and bonuses. An RTP of 96% and a very enticing gameplay with interesting feature, places this slot among the all-time classics.
- Jungle Jim El Dorado | A game based on the quest to find El Dorado in South America, this slot has 5 reels and 25 paylines.
Progressive Jackpot Slots
These slots online have proved extremely popular, as they offer players the chance to win a huge, multi-million prize with a relatively small stake.
A small portion of each player’s stake contributes to the jackpot, which continually rises until a player finally triggers it. There have been many instances of players receiving seven-figure and even eight-figure prizes lately.
Top progressive jackpot slots online of 2023 include:
- Mega Moolah | Don’t be put off by the less-than-generous RTP of 88.12% and pretty basic gameplay – this slot is responsible for several record-breaking wins and has paid out over €1 billion in its lifetime. And one lucky player has won €18.9 million on one occasion.
- Age of the Gods | A game based on the Greek Gods, this slot has a 95.02% RTP, 5 reels and 20 paylines.
- Mega Fortune | This slot has a theme based on success and luxury living, with yachts, champagne and expensive watches featuring heavily. It has an RTP of 96%, 5 reels and 25 paylines.
Fruit Machines
These online slots mimic the machines that you will find in bars and arcades across Ireland, featuring 3-5 reels and a payline in the middle. These are classic, old-fashioned slot games, but the online fruit slots that you can play at the leading Irish slot sites, are actually new and modern games with a bit of an old-fashioned twist.
Symbols generally include classics like fruit, bells and the number seven. They give you the option to hold or nudge reels, adding another layer of intrigue. They give you the option to hold or nudge reels, adding another layer of intrigue.
The best fruit machine games at online slots sites for 2023 include:
- Fruit Shop | A fairly simple game with a market stall design and cartoon graphics, this slot boasts a 96.71% RTP, 5 reels, 3 rows and 15 paylines.

- Fruit Fiesta | Available in 3 reels or 5, this classic fruit machine design has an RTP of 90.09%.
Irish Slots
Irish slot have a special place in the world of online casinos and are particularly revered in Ireland (where else?!). The theme and the symbols are pretty common - leprechauns, shamrocks, beer, pots of gold, potlucks and what not.
- Leprechaun Goes Wild | This Play'n GO slots is one of the favourites with the leprechaun as the main symbol. One curious element about this game is that it features 6 wilds, hence the name.
- Emerald King | This Pragmatic Play slot has a really fun feel to it. It can be played with as little as 20 Eurocents and the maximum amount you can win is 20,000 coins.
- Gaelic Luck | This Playtech slot features both great graphics and a pretty high RTP of 97.06% so it has all the elements to be a fan's favourite. The jackpot prize is 10,000 times your line bet and it is available at most, if not all Irish slot sites.
- Celtic Charm Fire Blaze Quattro | Another Playtech slot which was launched last year, this game comes with Fire Blaze’s Hold and Respin feature and a maximum win of 2588 times your bet!
There are many slot games out there, but we figure these might find a special place in your heart. Sláinte!
Branded Slots
The trend for themed slots online has accelerated over the past few years. They are similar to video slots, but they follow a narrative based on a famous movie, TV show or band. Basically, these are slots that you can relate to.
Some of the best for 2023 are:
- Game of Thrones | Fans of the epic TV and book series will love this 5-reel, 15-payline slot with 4 free spins features based on the Houses of Westeros.
- Rocky | A slot based on the legendary movie franchise, Rocky features 5 reels and 25 paylines.
- Guns ’N’ Roses | This slot online, with 5 reels, 20 paylines and a generous 96.98% RTP, is set against a concert stage and has a selection of some of the band’s classic songs for you to choose as background music.
- Thor |This game is based on the famous Marvel superhero, Thor, or to be more precise on the second film in the Thor series - Thor: The Dark World. The game has multiple bonus features and the maximum amount you can win in the base game is 1,000 coins.
How We Rate Slot Sites in Ireland
The CasinoSource team of expert reviewers performs a thorough assessment of all the different sites featuring online slots before making recommendations. They sign up for an account at each site and monitor the simplicity of the process, while also assessing the level of security provided.
Once they are in, they test the online casino bonuses offered by the site and compare them against rival sites to see how much value they offer players. Our reviewers will make deposits via various methods and play the slots online offered, testing them across multiple factors including entertainment, speed, graphics and usability. They make withdrawals and make note of how long it takes for payouts to arrive, while also interacting with customer service representatives and gauging how polite, professional, helpful and friendly they are.
The key criteria they look for are online slots variety, game quality, user experience, bonuses and the types of slots on offer. They give each online casino a rating for these five categories, while also breaking each review down into bonuses and promotions, registration, deposits and withdrawals, experience, mobile play, software, game choice, VIP programmes, customer support, security, responsible gambling and more.
The best Irish online slots sites should work well on a number of devices, provide a compelling range of online casino welcome bonuses and offer a wide range of different banking methods. They have a history of paying customers on time, treating them with respect and keeping personal and financial details secure. We only recommend trusted sites that tick all these boxes.
Our reviewers constantly pay attention to the new online slots sites that are launched, as exciting new operators continue to muscle into this space. They also revisit sites on an ongoing basis to check that they maintain the highest standards, ensuring that you receive up-to-date information at all times.
Free Spins and Wagering Requirements
Most sites offer online slot bonuses in a bid to attract new customers. These bonuses are varied, and they come with different wagering requirements attached, so it pays to shop around for the best offers.
For example, one site might offer a 200% welcome bonus up to €500, plus 50 slots bonus spins, meaning you will receive €750 to play with and 50 extra spins if you deposit €250 of your own money. A rival site might offer a 100% welcome bonus up to €300, plus 300 extra spins. That would give you €600 to play with, along with 300 bonus spins, if you deposit €300 of your own money. Bear in mind that the bonus amount and the number of spins aren't the only figures you should be taking into consideration when deciding whether a casino bonus is better than the offer by a rival site.
Another important factor to bear in mind is the wagering requirement, otherwise known as the rollover requirement. While some slot sites offer a no wagering bonus, what this term refers to is the number of times you need to play this bonus credit before you can think about making a cash withdrawal. For this reason, many players like to find the lowest wagering requirements for bonuses on popular slots online.
Ideally you want the largest matched deposit bonus possible, as many daily free spins as possible, and the lowest rollover requirements possible. You generally have to make a compromise when selecting casino bonuses, but some sites offer a really compelling, rounded bonus in a bid to attract new customers.
Some online slots sites also offer a free spins no deposit offer, which are well worth accepting, as you do not need to deposit any of your own money and you could earn a cash withdrawal if you are successful.
