The top slot sites and best online slots, reviewed and ranked by Gambling.com’s slot experts.
Our Irish slots guide includes everything you need to know - from game types and mechanics to key features, themes and the latest slot bonuses.
With hundreds of online slot sites available in Ireland, our experts, led by Paul Twaddle, have carefully selected the best slot sites based on key criteria:

Key Features: Their non-stop drop cash prizes pool is currently standing at €2,300,000. Their Spinomenal Tournament cash prize pool also has a grand amount of €500,000.
Megaways is now such a popular online slots format, that we have researched slot sites that offer the biggest variety of Megaways games in Ireland.
Here are my top three picks for the best Megaways slot sites in Ireland.
With 100 Megaways slots, users are spoilt for choice at Vinyl. Test the waters with some Irish-themed choices such as Leprechaun’s Magic Megaways and Golden Leprechaun Megaways or try out the popular Big Bass Bonanza Megaways series.
Key Features: Slots players can gain bonus crab credits, allowing you to grab a prize such as bonus money, coins, or even free spins.
Dublin Bet is, as you can probably guess, is an Irish online casino. With over 80 Megaways slots, you might just want the luck of the Irish on your side. Try out Great Rhino Megaways and join their Drops and Wins promotion, or try The Money Men Megaways slot game, a personal favourite.
Key Features: The Drops and Wins prize pool is currently worth over €30,000,000. Dublin Bet offers regular slot promotions and a fantastic sign-up bonus to new Irish players.
Golden Bet excels when it comes to its number of online slots, boasting over 100 Megaways titles such as The Dog House Megaways and Black Gold Megaways. Play certain Megaways titles to enter the Drops and Wins promotion such as Mammoth Gold or Great Rhino for a little bit of an extra thrill.
Key Features: Join their slot race every time you play any slot game on the site and be in for a chance to win free spins and even cash prizes.
Many online slot sites in Ireland offer customers regular online slot promotions and bonus spins to extend their gameplay or reward loyalty.
Here I detail what I consider to be the best online slot Ireland promotions in 2025:
Snatch Casino has one of the biggest promotions I’ve seen at a slot site in Ireland to date. Get 450% up to €6,000 and 325 free spins when you're a new player. Or join their ‘February Spin Win Quest’ with a prize pool of up to €20,000.
Key Features: Get 50% up to €300 and 50 free spins every Wednesday and not only that, but you can get 50% up to €500 and 25 free spins every weekend as part of their weekend reload bonus.
Lukki Casino has been making big strides in the world of online slots. Join their daily slots promotions such as the Spin’n’Win Wednesdays where you can get 30 free spins every Wednesday an unlimited amount of times. Use your free spins on selected slot games such as Belatra’s Big Will Buffalo.
Key Features: Get another 50 free spins an unlimited amount of times every Sunday as part of Lukki Casinos Sunlit Sunday Spins promotion.
With OJOPlus, players get a whole load of perks, well after your initial casino sign-up bonus. Get money back every single time you play an online slot at PlayOJO. You can get a real cash reward at the start of every month, which is matched to your previous month's winnings.
Key Features: Enter their ‘Reel Spinoffs’ package and have the chance to win 1000s of free spins to use on any slot game you want.
New online slot sites are highly sought after for their modern designs, fresh content, and latest features.
Here are my top three recommendations for the best new slot sites in Ireland.
With a massive selection of 10,000 slot games, FatFruit offers endless options for players. One advantage of newer slot sites is their ability to stay ahead of industry trends, ensuring users always have access to the latest features. FatFruit supports both traditional payment methods and a variety of cryptocurrencies, even dedicating an entire section to crypto slots, a rarity among more established platforms.
Key Features: Slot players can enjoy daily promotions, earning rewards like free spins and bonus cash.
Launched in 2024, Malina has quickly become one of our top choices for slot users in Ireland. Malina already has an impressive collection of over 12,000 slot games. This new online slot site offers a selection of slot options, including more than 1200 jackpot slots and numerous slot tournaments held every month.
Key Features: Enjoy an exclusive welcome bonus of 200% up to €2,000, plus 200 free spins.
Real Spin has been making waves in the online slots scene, since its launch in 2024. Offering a dedicated section for video slots featuring popular titles like Hell Hot 40 and 12 Coins, players can enjoy a wide range of slot game options. With over 180 jackpot slots available, slot users can enjoy nonstop excitement and big-win potential.
Key Features: Take advantage of a variety of promotions, with the chance to claim up to 300 free spins each month.
The best slot sites offer exciting sign-up bonuses, including free spins, alongside regular promotions and rewards for loyal players.
These sites feature a diverse selection of slot games with unique themes from top software providers, along with the latest releases and the biggest jackpots.
When reviewing slot sites, we ensure they are licensed and regulated, which guarantees fair play and security.
The earliest online slots in Ireland were quite straightforward, typically featuring five reels with three rows. The very first online video slot to include a bonus round, known as 'Reel ‘em In’, was introduced in 1996.
Fast forward almost two decades and today's slots users are presented with an entirely new generation of casino slots, offering various formats and enticing features.
Unsurprisingly, these slots draw inspiration from traditional pub fruit machines. They typically feature a retro style and are composed of either three or five reels, with basic graphics and sounds.
Reel King is a prime example of a fruit machine slot that has made a successful transition from a pub kiosk to online slot sites, including at one of my online casinos, PlayOJO.
While NetEnt’s Gonzo’s Quest and Starburst are considered modern-day classics, purists often classify true classic slots as games like IGT’s Da Vinci Diamonds.
With an impressive 117,649 ways to win, it’s easy to see the appeal of the innovative Megaways game mechanic, especially when the cost per spin can be as low as €0.20.
Games like Wild Celebrity Bus Megaways demonstrate how this innovative feature can be integrated into popular online slots.
A blend of slots and bingo, Slingo offers a unique gaming experience which sees players complete bingo-style grids with numbers spun on a slot reel.
The goal is to match numbers to complete winning lines (‘Slingos’) and advance up the prize ladder towards a full house and the top prize.
"Slingo has gained significant popularity, leading to the creation of franchised versions like Tetris Slingo, Britain's Got Talent Slingo and my favourite, Starburst Slingo"
Nowadays, game developers are eager to create highly volatile online slots, providing players with the opportunity for larger, but less frequent wins.
Hacksaw Gaming, in particular, are renowned for its extremely volatile online slots, with titles like Wanted Dead or A Wild. In these games, it truly is an all-or-nothing experience, emphasising a high-risk, high-reward style of gameplay.
Many seasoned slot users, myself included, have yet to hit ‘max win’ on one of the highest-paying slots.
NetEnt were the first to break the 100k barrier with Dead or Alive 2, offering a maximum payout of 111,111x your stake, later surpassing it with the release of Starburst XXXtreme at 200,000x.
However, Nolimit City's Tombstone RIP now tops the charts, with an unprecedented 300,000x payout, achieved soon after the game’s release in January 2022.
Such wins are among the reasons why Nolimit City slots have secured a place in the favourite slots lists of many players.
The dream of landing a substantial fortune is on offer with progressive jackpot slots, with each bet contributing a small portion to a continually growing jackpot.
These progressive slot pools keep on increasing until one player strikes it rich.
The biggest are the WowPot and Mega Moolah series of jackpot slots, but below I've listed all of the big online slots jackpots currently up for grabs for users, along with the best online slot sites in Ireland where you can try your luck for each.
Jackpot Series | Current Jackpot | Where to Play (Ireland) |
WowPot | €5 million | MyEmpire |
Mega Moolah | €8.2 million | Dream Vegas |
King Millions | €3.1 million | 50 Crowns |
Dream Drop | €2.7 million | 50 Crowns |
Jackpot King | €3.1 million | PlayOJO |
Mega Jackpots | €842,444 | BetVictor |
Age of the Gods | €168,457 | Bet365 |
The biggest online progressive jackpot payouts have mostly been won on the WowPot and Mega Moolah series of slots.
Microgaming launched the safari-themed Mega Moolah progressive jackpot slot back in 2006 to much acclaim. In 2015, it paid out a £13.2 million jackpot to Jonathan Heywood from the minimum 25p stake.
Since its release, the game has expanded into a series of titles that all feed into the same jackpot, such as Absolootly Mad, which paid the largest Mega Moolah jackpot of £16.9 million in April 2021.
That huge win came just two weeks after a WowPot jackpot of £15.2 million was won by a UK slots player on the Book of Atem online slot.
However, WowPot regained its crown with a world-record online slots jackpot of £33 million, won in late 2023 on the aptly named Wheel of Wishes.
While the slots above all contribute into shared jackpot pools, the following slots are stand-alone games, each boasting its own progressive jackpot:
Jackpot Games | Current Jackpot | Where to Play (Ireland) |
Jackpot Giant | €7.5 million | Bet365 |
Leprechaun's Luck | €3 million | Bet365 |
Beach Life | €2.8 million | Party Casino |
Mega Fortune | €2.4 million | 888 |
Hall of Gods | €2.1 million | Bitkingz |
These individual casino slots can still pay out staggering jackpots, including the €17.9 million won on Mega Fortune by a Finnish player.
While the biggest progressive jackpots can take weeks or even months to be paid out, there are also daily jackpot games that are guaranteed to payout every day.
Sometimes called ‘Daily Drop’, ‘Must Drop’, 'Must Go' or ‘Must Win’, these progressive jackpots ensure a jackpot winner each day.
At the best slots sites, you can watch the countdown of when the daily jackpot ‘must drop’ in their games lobby and choose to play just before the jackpot time limit is up.
Here are some of our favourite daily jackpot slots for users:
There’s an endless variety of online slot game themes to choose from, catering to all preferences. Below I’ve categorised the most popular themes and shared my personal favourites from each.
The world of animal-themed online slots can transport you to the North American plains, Amazonian jungles, the depths of the ocean, or simply feature your favourite pets.
Part of the Big Bass series from Pragmatic Play, this slot offers engaging gameplay with clean artwork. The free spin bonus round features a ladder trail with extra spins and an increasing multiplier for each unlocked level.
Another great slot from Pragmatic Play and one of the earliest to feature the Megaways game mechanic. The free spin bonus round presents a choice between Sticky Wilds or Raining Wilds, both with the potential for mega payouts.
There’s zero chance I could leave Lucky Irish-themed slots off this list. Such is its popularity, for some players, there simply are no other types of online slots.
This slot from Gameburger Studio, which uses the same game engine as their other hit slot ‘9 Masks of Fire’, offers a charming Irish quest, with catchy tunes and vibrant symbols such as rainbows and pots of gold. Trigger the free spins bonus round to receive a 3x multiplier with the possibility of unlimited retriggers, while landing nine scatters wins you the jackpot.
In my opinion, this is one of Playtech's most underrated online slots. Triggering the Cash Collect feature on reel 5 can lead to winning all cash prizes or activating the free spins bonus round. Plus, there are four Cash Collect fixed jackpots available, determined based on a multiplier of your stake.
The traditional ‘fruit machines’, named for their reel symbols of grapes, plums, oranges, lemons, bananas, melons and cherries, have long been a staple in local pubs. Thus, it's no surprise that online slot developers sought to capture the essence of the pub ‘fruity’.
With colourful candy bar symbols adorning the reels, Sweet Bonanza stands out as one of Pragmatic Play’s most successful slots to date. Unlike traditional slots, the reel symbols tumble rather than spin, and this ‘Anywhere Pays’ slot offers a win multiplier of up to 100x in the free spins bonus round.
Another great Pragmatic Play slot, Fruit Party is a ‘Cluster Pays’ game with cascading wins. Unusually for an online slot, the maximum win of 5,000x can be achieved through the base game and not just the bonus round. This is largely thanks to the multipliers that increase with each win, potentially reaching up to 256x.
Pirate-themed slots invite players to set sail on thrilling adventures in search of hidden treasures. Packed with swashbuckling characters, treasure maps and stormy seas, these games offer exciting gameplay and plenty of chances to uncover bountiful rewards on the high seas.
A Hollywood style cinematic intro gives you high expectations of this 2021 release from Relax Gaming - and it doesn’t disappoint. Dead Man’s Trail offers a rewarding Coin Feature during the base game along with a Trail Bonus round where you can win up to 50,000x your stake.
Considered a classic by many seasoned slot players, this Novamatic slot offers a 50/50 gamble feature after each win. It gives you the chance to infinitely retrigger more free spins during the bonus round, complemented by a 4x multiplier.
While most slot games fit into popular theme categories, there are many cult favourites that don’t easily fall into these verticals. With that in mind, we’d like to pick out a few of our all-time favourite classic slot games that stand out for their timeless appeal and unique charm.
Launched back in 2013, the brilliantly simple slot from NetEnt is without doubt the most played online slot game ever. There isn’t a traditional bonus feature, instead the key to big wins lies in the expanding Starburst Wild symbols, which remain sticky while triggering one or two re-spins. This unique game feature has contributed to the game’s enduring popularity.
Themed around the Yukon trail, Bonanza was responsible for a flurry of similar themed slot releases - all of which were literally trying to jump on the gold rush bandwagon. Smooth gameplay is complemented by a quirky soundtrack and plenty of ‘yee-haws’ when you land a big win on this Big Time Gaming slot.
Rich Wilde and the Book of Dead is a popular Egyptian-themed slot game by Play’n GO. Featuring a five-reel, 10-payline setup, it follows adventurer Rich Wilde as he uncovers ancient treasures. With expanding symbols and free spins, this high volatility slot offers thrilling gameplay and a maximum win of 5,000x.
This legendary release from NetEnt is a five-reel, 20-payline slot featuring an adventurous conquistador searching for El Dorado. It introduced the Avalanche feature, where cascading symbols replace wins, increasing multipliers up to 5x in the base game and 15x in Free Falls. A medium-high volatility slot, it offers edge-of-your-seat gameplay.
I love the nostalgic feel of this Blueprint slot, based on Spielberg’s 1980’s cult classic film where you can join Mikey, Chunk and the gang as you hunt for One-Eyed Willy’s treasure. Fans will instantly recognise iconic moments like the ‘Hey you guys’ intro from the toothless Sloth and with randomly awarded bonus features during the base game, plus the potential of landing the ‘red’ Super Bonus and No Lose gamble, this ranks among my all-time favourite slots.
Whilst the basic concept of most online slots is the same, many offer a unique mix of game mechanics and features that impact gameplay and potential winnings.
Here is my summary of the main characteristics of online slots:
When you fire up any online slot, the first thing you’re presented with is the base game which offers the standard reel configuration and symbols for that particular slot.
A quick dip into the information section and you’ll find the paytable which displays the value of each reel symbol and the payouts for winning combinations. The base game is usually straightforward and you just need to choose your bet size and start spinning.
The bet size, also known as the spin value, allows you to customise your play and tailor wagers to suit your budget. The way it is calculated can vary for different slot games, but typically includes the following elements:
Most online slots require a minimum of three matching symbols to create a win, although some slots pay for matching just two of the highest-value symbols.
Traditionally, winning combinations are formed by matching symbols on adjacent reels, with the default being left to right although innovation has brought us a number of interesting payout structures, including:
While the base game creates more frequent and occasional big payouts, it’s the bonus round that unlocks the premium symbols with the largest multipliers for the biggest wins.
The bonus round is usually triggered when three or more Scatter symbols are landed, which then awards free spins along with enhanced features and multipliers, such as:
Slots tournaments add a competitive edge to spinning the reels, with additional rewards above and beyond regular slots gameplay.
In these scheduled tournaments, players compete against each other to win cash prizes or other rewards.
While each slot tournament has its rules, the goal is always to accumulate points to rise on the leaderboard.
Here I have listed the tournaments currently available at Irish slot sites:
Slots Tournament | Prize Pool | Where to Play (Ireland) |
Drops & Wins (Weekly) | €255,000 | MagicRed |
Drops & Wins (Daily) | €35,000 | LeoVegas |
Mega February Race (Monthly) | €33,350 | Snatch |
Slot of the Week (Weekly) | €1,100 | Vinyl |
The most popular online slots tournaments in Ireland are Drops & Wins, available exclusively on Pragmatic Play slots games.
With a monthly prize pool of €2 million, this promotion offers prize-paying positions on weekly tournament leaderboards, plus random daily prize drops:
Our slots team especially enjoys the random daily prize drops, which gives everyone who plays a chance to win - not just those who make it onto the weekly leaderboard.
For beginners and seasoned players alike, playing online slots can be an exciting and potentially lucrative pastime. To maximise your enjoyment and improve your chances of winning, here are some key strategies and tips to consider:
1. Understand the Basics: It's good to grasp the basics before you start playing. Understand what paylines, reels and symbols mean. Learn about different types of slots – classic, Megaways, progressive jackpots and more. Also, get familiar with terms like Return to Player (RTP) and Volatility. RTP refers to the percentage of all wagered money a slot machine will pay back to players over time, and Volatility relates to the risk level associated with a particular slot game.
2. Choose the Right Slot: With the vast array of Ireland slots available, selecting the right one can seem daunting. The key is to find a slot that fits your preferences and playing style. Consider factors like the theme, volatility and bonus round options.
3. Utilise Free Spins and Bonuses: Most online slot sites in Ireland offer free spins, bonuses and promotions. These can be a great way to try out a game before risking real money or to extend your playtime. Always read the terms and conditions associated with any slot bonus, as there can be wagering requirements or other restrictions.
4. Manage your Bankroll: Responsible gaming involves setting a budget for your online slot play and sticking to it. Never wager more than you can afford to lose and consider setting a time limit for your play sessions to prevent getting carried away.
5. Keep it Fun: While we all enjoy daydreaming of spinning a huge payout, I rate a slot according to its theme, game mechanics, artwork and the quality of the sound effects - elements that truly enrich the experience of playing slots online. Remember, the primary goal of playing slots is entertainment. Keeping this perspective can help make your online gaming experience more enjoyable.
To better safeguard Irish online slots casino players, measures may be taken to eliminate credit cards for online slots, along with discontinuing VIP memberships and free bet promotions, which are considered predatory.
The Gambling Regulatory Authority of Ireland (GRAI) will be assuming the responsibility of issuing casino licences in Ireland. Stay tuned for updates on GRAI and any forthcoming developments.
