How We Picked Slot Sites in Ireland

  • The top Irish online slot sites offer enticing sign-up bonuses, such as free spins, along with regular slot promotions and rewards that help you to improve your chances of winning.
  • We select sites with high-quality games from the best providers in the industry, as well as the latest release. When ranking the best new casinos, we typically try to find sites that offer a broad range of online casino games to enjoy from multiple game providers, including big names (such as NetEnt or Playtech), as well as some more niche titles.
  • Any online slot site that makes it to our hand-picked selection is licensed and regulated by some of the strictest gambling commissions to ensure fair play and player security. Only official gambling commissions license all new trustworthy online casinos listed by BonusFinder, so you can rest assured that they are legal websites that adhere to current safeguards and regulations.
  • Transparency in operations builds trust, and we prioritize it highly because the online slots industry can be full of scams. If a company already owns a brand that scams its players, it will probably do it again. That’s why we try to check their associations arduously.

Our Top Picks for Best Online Slot Sites August 2024

With no further ado, here’s our selection for the best online slots in Ireland in 2024!

Best Slot Sites for Progressive Jackpots

Progressive Jackpots are great for players who want bigger wins. When you play these games, the jackpot increases after every game, increasing the bonus amount that resets when someone hits the jackpot. Sometimes, depending on your total bet, you might spin the prize wheel or land on a bonus symbol several times. All players contribute to the big jackpot, with more money added per spin. Below is our selection of the best slot casinos with this feature:

Party Slots

Party Casino has some of the most exclusive titles in their casino. Developed in-house, these titles boast huge progressive prize pools reserved exclusively for the players at Party Casino. The progressive prizes available at Party Casino include The Big Series Jackpots, The Cash Flash Jackpots and The Gold Jackpots, and all are capable of awarding game-changing wins.

Betonic Slots

With nearly 200 games, Betonic has the largest amount of providers in its jackpot library – 24! Here you can play your favourite online slots such as Sweet Bonanza and Extra Chilli Megaways.

Novibet Slots

Novibet Casino has over 150 Megaways slots to choose from. You also have your pick regarding progressive slots, with popular games such as Microgaming’s Mega Moolahs Absolootly Mad and Immortal Romance.

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.

Best Slot Sites for Megaways

The Megaways format has been a constant trend in Ireland for a while, so I decided to take a look and catalogue the slot sites with the best selection of this exciting game.

Boomerang Casino

With more than 200 Megaways slots, the fun is guaranteed at Boomerang Casino. You can rock on with Monsters of Rock Megaways or try out the popular Gonzo’s Quest Megaways series.

Wild Fortune Slots

Get on for the wildest slot ride! Wild Fortune delivers what its title may suggest: a savage array of top-class Megaways. Give a chance to Shamrock Holmes or try the Hot Spin Megaways.

Revolution Casino

Revolution Casino offers a revolutionary number of slots for a single online casino. Here, you can play more than 400 different slots, so if you were to try a new game every day, it would still take you over a year to try all of them out! My personal favourite is 777Hot-Ice, but there are some other high-quality games too, such as the Super Pachinko series and the Mot?rhead video Slot!

Best Slot Sites for Promotions & Free Spins

The best online slot sites in Ireland offer great promotions to their most loyal customers on a regular basis. These oftentimes come in the form of bonus spins with which you can extend your gameplay.

Below what, in my opinion, are the best online slot promotions in Ireland that you cannot miss in August 2024:

SpinsBro Slots

Spinsbro Casino has one of the best promotions I’ve seen in Ireland for a long time. You can get a 115% bonus on your first deposit of up to €420, and a total of 1,000 bonus spins and a bonus of €2,120 during the four first deposits you make.

Rollino Slots

Rollino Casino is the place to go if you want to get the massive € 4,000 bonus. When signing up, you get 20 free spins no-deposit for Book of Dead plus 325 bonus spins to play on Dog House and Big Bass Bonanza, among other titles.

Stake.com Slots

Stake has for sure the most valuable offer at the moment, with a 200% bonus up to €1,200. This means that if you deposit €1,200, the casino will give you the same amount in the form of a deposit bonus– no strings attached.

Types of Online Slots

The online slots industry has evolved significantly since its origin at the end of the 1990s. Back then, the game mechanics were quite straightforward, featuring five reels with three rows most of the time.
It’s been almost 30 years since then, and nowadays, players have at their disposal a neverending variety of online slots coming in different formats and with attractive features.

Fruit Machine Slots

The classic among the classics: the vanilla ice cream of online slots. Fruit Machine slots take us back to traditional pub fruit machines. If you are nostalgic and want a gaming experience that simulates reality, this is your way to go.

Classic Slots

Did you know that the first slot machine was the Liberty Bell designed by car mechanic Charles Fey all the way back in 1894? The original ‘One-Armed Bandit’ had three reels which were spun by pulling a mechanical lever on the side, and paid out a jackpot of 50 cents. The slots games you will find in today’s online slots sites have come on a bit since then, but they still hark back to the simplicity of the first designs.

Playing classic online slots can be a calmer and more relaxing experience than games bursting with bonus features to keep track of. Classic games also have some of the highest RTPs, making them the perfect choice when you need to play through a wagering requirement.

Due to its simplicity, player favourite Starburst can be considered a classic slot. Best online casinos in Ireland give free spins bonuses for Starburst because this is a great game for first-timers and has an enduring appeal with more experienced slots players. Pay attention however to the terms and conditions that come with it, as they may have a direct impact on your chances of withdrawing your winnings.

Megaways Online Slots

Megaways slots are a relatively new way for gamers to experience online slot games. The exciting part lies within this game’s reel mechanics, which offer 243 to 117,649 ways to win each spin. This massive number of combinations has great appeal among Irish casino players, hence why the industry is launching new versions of this game nonstop.

Must Drop, Daily Drop and Mega Drop Jackpot Slots

One of the latest developments in online slots is the introduction of limited time jackpots such as the Red Tiger Hourly Jackpot you can find at 888 Casino.

Red Tiger first introduced the Must Drop concept back in 2016 when Paddy Power approached them to ask for a feature that would add excitement to slots players during the UEFA Euro Cup. Thus the Must Drop was born, as a slots jackpot that had to be to be won by the end of the game. The closer time got to the full 90 minutes, the greater the chance of winning, and the higher the level of excitement!

Daily Drops jackpot on other hand promise to drop the big prize every day before 22:00 GTM, so the closer the clock is to that time the higher chances you have to win if it the jackpot hasn’t dropped yet.

At last, Mega Drop Jackpot Slots are progressive jackpots that drop before they reach a maximum payout value rather than grow indefinitely. These usually have quite massive prizes waiting to be claimed, such as Megaways Elephant King’s €800,000 prize.

Slingo

Slingo combines the best of bingo and slots to create a new gaming experience in which players must complete a bingo-style grid with the numbers they get after spinning the reels. The key to winning is the same as in bingo: complete the winning lines, AKA slingos, to move up the prize ladder towards the big prize.

There are numerous franchises with their own Slingo version. Some of my favourites are Space Invaders Slingo, Friends Slingo and my all-time-favourite, Tetris Slingo.

Cluster Pay Slots

Compared to regular slot games,Cluster pay slots add more fun and possibilities of winning thanks to its new mechanic. Introduced by NetEnt in 2016 on its game Aloha! Cluster Pay, this new mechanic does not count your winnings by aligning the same symbol in one payline, but having a number of matching symbols next to each other. The cluster system replaces the traditional Payline system from the regular slots, where you need to align the symbols along predefined paylines in order to win.

The symbols need to touch horizontally or vertically, and the minimum size of the cluster needed to trigger a win usually is 4 or 5. Still, it can vary depending on the game you are playing. Mobile slots offer Cluster Pays slots on apps or your browser, so you can also enjoy this game on the go.

Video Slots

All of the online slots games you will find at an online casino site are technically video slots, as the reels are electronic rather than mechanical. However, when we talk about video slots we are normally talking about games that have more excitement than the classic slot. These games tend to include lots of extra features such as multiple pay lines, slots bonus rounds, and even mini-games.

Video slots have great graphics, thumping soundtracks and are more immersive to play. Many also feature a longer storyline or narrative, and familiar or iconic characters. Some of the most popular video slots for Irish players include Gonzo’s Quest, Book of Dead and Dead or Alive.

Megaways Casino Slots

Megaways casino games shook up the online gambling world when Big Time Gaming first released Bonanza in 2016. Nowadays, you can find Megaways versions of all the most popular slots and almost any theme imaginable from Ancient Egypt to the furthest reaches of the future.

Megaways slots are so appealing because they have many more ways to win than your standard slot. They have six reels with 2-8 symbols showing on every spin, creating up to a maximum of 117649 paylines. Our favourite Megaways Casino is definitely Party Casino, which has a dazzling selection of over 100 Megaways slots, including all the classics and some rarities like Shamrock Holmes which combines our favourite consulting detective with the magic of the Emerald Isle.

Progressive Jackpot Slots

Many online slots will boast of big jackpots, but it is the progressive jackpot slots that have the capacity for truly life-changing wins. The casino or developer sets standard jackpots and do not change. Progressive jackpot slots, on the other hand, keep increasing the more times the game is played until one lucky winner scoops up the prize.

The game developer hosts the biggest progressive jackpot slots, and several different games and different casinos will share the jackpot. This huge player base allows the jackpots to grow into six-figure sums, as the jackpot takes a small cut from each spin made on any of the games included.

The most popular progressive jackpot slot in Ireland is, without a doubt, Mega Moolah. If you want to see what all the fuss is about, then head over to Zodiac Casino and get 80 Mega Moolah spins for just €1. Please remember to play responsibly.

Online Slots Tournaments

Slots tournaments are a pretty new way to play and are currently only available on some slots sites. These competitions pitch players against each other to top the leaderboard whilst playing a certain slot. The bigger tournaments can have prizes, including 5* holidays or must-have gadgets, but most will give smaller rewards like free spins or a few quid.

Taking part in a tournament is fun, and the competition brings a sense of community amongst online players, as you can see how everyone else is doing and compare your progress.

In 2024 more and more casinos are starting to host slot game tournaments. Mr Green Casino is one of the biggest and best with their Reel Thrill Slots Tournament. This is played on the Reel Thrill games, and the leaderboard resets every 15 minutes. Your score is calculated as a proportion of the profit from the 20 spins you make in this round, and the top 5 leaders are granted a real cash prize. Unibet, 32Red, and William Hill are other slots sites that run their own form of tournament.

Free Play

Some slot sites and casinos will let you “try before you buy” and play games in demo mode. This is a great way to understand how a slot works before you play, but due to UK Gambling Commission regulations, you need to be registered at the site and prove your age to be able to play slots for free.

mobile slot machines

In 2024 most online slots sites are designed to be played on your mobile device, and many will now let you pay by phone bill as well! Play responsibly.

Online Slots Software Developers and Casino Game Providers

With a few notable exceptions, most Irish casinos will feature a range of slots by several different game providers. There are hundreds of large and small studios creating new and exciting slots and casino games, and different game-makers will specialise in certain features or gameplay styles. Many larger studios have bought the rights to make slots for a TV or film franchise, or their own game characters will be so popular that they have become a brand of their own. Here are a few of our favourite game developers in 2024:

Microgaming

Microgaming is one of the biggest slot developers in the world, both in terms of the number of casinos that have their games and the sheer quantity of titles that they have created. They have so many games to choose from that there are a number of Microgaming Casinos who don’t see the need to sign-up with any other game providers, as Microgaming have all bases covered.

Mega Moolah is far and away the most popular Microgaming Slot, as players go wild for its exciting features and huge progressive jackpot. The Guinness World Record for largest online slot win is held by a British man who walked away with a whopping €13,209,300 after hitting the Mega Moolah jackpot on 6 October 2015.

Microgaming also lead the pack when it comes to signing lucrative deals with popular franchises, and have made slots versions of fan favourites such as Game of Thrones, Battlestar Galactica, and Jurassic Park.

NetEnt

NetEnt is a Swedish company that has given us some of Irish player’s most wanted slots, including Starburst, Gonzo’s Quest, and Finn and the Swirly Spin. NetEnt also have the rights to some popular franchises, including Narcos, Knight Rider, and Gordon Ramsey’s Hell’s Kitchen.

Yggdrasil Gaming

Although you won’t find Yggdrasil Gaming’s slots in as many casinos as the bigger studios it is well worth hunting them down. Yggdrasil are committed to creating a higher quality gaming experience for slots players, and their graphics are second to none. Check out Vikings Go Berserk, and Blood Moon Wilds as two of their top titles.

Playtech

Playtech are probably best known for their Age of The Gods games, which draw on Greek mythology and multiple bonus features to create a lasting legacy. There are many variants of the basic game to choose from, but our favourites are Age of the Gods – Goddess of Wisdom, and their recent foray into the Nordic legend, Age of the Gods Norse – Gods and Giants.

Play’n GO

The most famous Play’n GO game is the monumental success Book of Dead. Players just can’t get enough of the slot’s protagonist Rich Wilde, and he has taken on a life of his own and spawned many sequels. What really makes Play’n Go’s games stand out is the exciting stories that unfold as you play, and a range of bonus rounds and features that are lacking in many competitors’ lacklustre copies of these games.

IGT

IGT makes both online slots and real world live casino slots that you can find all over the world in brick-and-mortar casinos. They have created a range of branded video slots, including Transformers, Harley Davidson and Ghostbusters, and also have the most cat-themed online slots of any game provider we have reviewed, including Kitty Glitter and Prowling Panther.

Red Tiger

Red Tiger slots are some of the most sought after games in 2024. One of the reasons is their epic progressive jackpot slots, and their Daily Drops. The main reason though is the quality of their games which are chockablock with surprises and bonus features. Their most popular games include Piggy Riches Megaways, Narcos Mexico and Primate King, but one of our favourites is the highly volatile Reptizillion Power Reels!

Red7 Slots

Bristol based studio Red7 Mobile were renowned for making slots that worked perfectly on hand-held devices since the dawn of smartphones in the 2010s. They were acquired by gambling industry giants Scientific Games in 2017.
