Top Five Free Slot Games Casinos in Ireland 2023

Let's start with the question that probably interests you the most - which are the best casinos in Ireland that have free slots - no download options? Why? Because the purpose of demo games is to try them out for free to see if you like them and possibly spin the reels with a real money bet. Therefore, every good online casino should offer free slots to play for fun. Check out the five best Irish gambling sites for free slots online in which no deposit is required for playing.

Palm Slots


Although it appeared in the Irish gaming market in 2022, Palm Slots casino is already widely known. The operator is governed by European Union gambling laws and is licensed by Curacao eGaming. The casino has a catalogue including more than 2,500 slot machines, which are divided in the lobby menu into 11 sections so that players can quickly find a game to their taste if they do not already have a title marked. Despite the wide variety of free casino slot games, if you happen to prefer another type, Palm Slots has you covered. With the availability of live dealer tables and game shows, lottery games, and even sports betting, it is unlikely that you will not find something suitable for you.

Founded in 2022, RoyalistPlay Casino is another example of an operator that has quickly made its way into the online gambling industry, with a website that has everything a player could ask for in terms of gaming. Licensed by Antillephone N.V., Royalistplay is a legitimate mobile-optimized casino that you can access from any type of device. With more than 3,000 games in its library, the word "variety" takes on a different meaning here. At Royalistplay, you can try all kinds of free slot games, both in terms of theme and implemented mechanics. Aside from that, you can sit at a live dealer table or join a game show, place a sports bet, or play bingo.

Legend Play

Established in 2022, the Legend Play platform is licensed by Curacao eGaming. It is fully legal in Ireland, which means it operates in accordance with Irish law. One of the things that makes a big impression is that Legend Play has more than 15 approved payment methods if a demo game appeals to you and you decide you want to place a bet with real money. Legend Play has in its portfolio over 2,000 games that fall into the categories of casino and live casino games. However, the type of game that is favoured on this gaming site is none other than the slot machine. Proof of this is that approximately 95% of the games are slots. In addition, in Legend Play there is an opportunity to practice live sports betting, which is still not very common.

  1. ✅ 2,000+ Slot Machines
  2. ✅ Over 15 Payment Methods
  3. ✅ Live Dealer Tables
  4. ✅ Progressive Jackpots
  5. ✅ Live Sports Betting


Unlike the gaming sites listed above, Casumo Casino has been part of the Irish iGaming industry for over a decade. Licensed by the Malta Gaming Authority, this award-winning operator's focus is exclusively on casino games. This is the only gambling area that Casumo Casino develops, as it follows the mantra that each platform should have a specific purpose and develop within it. Casumo Casino's menu is user-friendly and divided into five categories, each of which has its own sub-categories for maximum speed navigation through the collection of over 2,000 games provided by 13 of the best software developers worldwide. In the live casino games section, you can find four main options: game shows, roulette, blackjack, and baccarat.

  1. ✅ 2,000+ Casino Games
  2. ✅ Progressive Jackpots
  3. ✅ Live Casino
  4. ✅ Mobile App
  5. ✅ 24/7 Customer Support



MrPlay casino went live in 2017, meaning that it is the second oldest in our top five selection of Irish casinos. What sets this operator apart from the rest? First of all, it has as many as three licenses from different regulatory bodies (Irish Betting Licence, UK Gambling Commission, Malta Gaming Authority), not just one. This is not to say that gambling sites with one licence are not reliable, but that MrPlay follows more rules to keep those licenses. Unlike the other casinos in our selection, MrPlay cannot boast of such a variety of games, but the operator bets on quality over quantity and at the same time strives to develop its sportsbook.

  1. ✅ 3 Different Licences
  2. ✅ 400+ Video Slots
  3. ✅ 100+ Live Casino Games
  4. ✅ In-Play & Live Sports Betting
  5. ✅ Mobile App

What Are Free Slot Games?

For people who do not have experience in the gambling industry, it can be difficult to understand what these free slots are. One might even question why they exist at all, considering that there is hardly a person who does not associate casinos with depositing money and playing games where there is a random chance of winning real money. So, what exactly are free slots?

Online slots, or rather the modes in which they can be played, are divided into two types: demo and real money mode. Both modes of all slot machines are developed by the same software provider. In terms of graphics, gameplay, and bonus features, they are not quite the same. But they have one significant difference. In order to play real money slots, you need to register at a casino, make a deposit, and place bets with real money.

Conversely, free casino slot games for fun have virtual fictitious money credited to you to play with without putting your money on the line. Not betting real money means that the winning combinations you see on the reels will not be actual cash, but again virtual fictitious money - just like the ones you placed bets with. You might ask what the point is of playing free slots.

Free slots are a good option for both experienced and new players. They give the chance for players to experience the gameplay and features of the slot without having to risk a single cent. You can try an unlimited number of free slots, each with its own virtual balance, to sift through the best games to your taste.

The list of free slots available in Ireland is huge and continues to grow. With this abundance of titles, it would be difficult to pick a game without being able to test it. Therefore, the virtual balance is a good option, as you can try out free slots with bonus and free spins features and judge whether they are slot machines that deserve to be played with a real money balance.

It would be helpful for new players to play free slots as this will give them an idea of what these games are all about. In addition, they use different mechanics, and the bonus features can be very diverse, therefore even if this is not your first encounter with the online gambling world, you can be surprised. That is why we suggest that experienced players also play free slots. Our site has a wide variety of demo games for you to try out.

Popular Free Slot Games Features

We have already mentioned that free slots can be very different from each other depending on the software developer, the mechanics implemented, the playing field, or the bonus features. However, what are the characteristics that we could call common, and what each of them means, see the following list.

  • Reels
  • There is no slot machine without reels. In practice, these are the columns that make up the game grid, with each rotation of which new symbols appear on the rows. The standard grid consists of three or five reels and three rows. Usually, the number of lines is directly related to the number of symbols that can land on one reel.

  • Paylines
  • Most free slots function with paylines. These are fixed lineups that will pay out a prize if you land matching symbols on them. The size of the payout depends on your bet and which game symbol forms the winning combination. In some free slots, such as Megaways games, instead of paylines there are ways to win, the number of which can exceed several tens of thousands thanks to the implemented special mechanics.

  • Symbols
  • Symbols are a mandatory element of any slot machine because without them winning combinations cannot be formed. They can be very diverse in terms of theme, but the standard symbols found in most free slots are fruits and suits of cards. Each symbol has a different value and according to it, they are divided into low-paying, medium-paying, and high-paying symbols.

  • Free Spins
  • What do free slots with free spins mean? When it comes to slots, free spins are usually obtained during a bonus round that is unlocked in a certain way. As the name of the term suggests, these are a given number of spins in a slot game that you can enjoy without your virtual balance being reduced (or if you are playing in real money mode without betting your money during those spins).

  • Bonus Rounds
  • Speaking of bonus rounds, they are the most anticipated stage of any game. There are almost no free slots that do not have at least one bonus round. Usually, each such feature is activated in a certain way, and once this happens, you are transported from the base game to a new playing field. Depending on the bonus round, you can get free spins, multipliers, or many other features that would increase the chance of forming a winning combination.

  • Bet Amount
  • Basically, this is the amount of money that you use from your virtual balance (or deposit in case you play in real money mode) to place a bet. In most cases, you have at least five different betting size options from which you can choose in order to fit into your budget. In terms of bonuses, the wager amount is the money you need to bet overall before being able to withdraw any possible winnings.

  • Autoplay
  • Almost all free slots released in the last few years have an Autoplay feature. What does it do? It allows gamblers to play the slot without having to constantly press the "Spin" button manually. Certain criteria are set such as the size of the bet with which to spin the reels, the number of spins to be played automatically, as well as when reaching what amount of lost money, the function will self-stop.

How to Play Our Online Slots for Free – No Download

Are you ready to spin the reels on some free slots? We bet you do! You do not need to worry about the gameplay being complicated or having to learn any game strategies. On the contrary, free slots are played in a very straightforward manner, which is actually one of the reasons for their popularity around the world. To see the best of the graphic design, sound effects, and gameplay, all you have to do is land at least three matching symbols on a payline. Since you may be a new player and may not be familiar with it, we took the liberty of making a short manual to guide you on how to play free online slots - no download required.

  1. 1️⃣ Select Your Favourite Game from Our Suggestions
  2. Browse the available games on our site. How can you do this? There are several possibilities. You can use the search engine or go to the "Play Free Games" category. After that, you will be able to browse our collection of games by flipping through the pages or sorting the free slots by the software developer. Another option is to open the Sitemap which can be found at the bottom of the page and read one of our slot reviews.

  3. 2️⃣ Check the Game Symbols’ Value
  4. After loading the demo game, click on the “Play” button. The first thing you should do is inform yourself about all the game features. What bonus rounds it has and how they are triggered, as well as which are the highest-paying symbols. Each game symbol in free slots has a different value. Generally, there are lower-paying, medium-paying, and higher-paying symbols.

  5. 3️⃣ Select Bet and Paylines
  6. The next thing you should check is how many paylines there are and where they are located. Why is this important? Because paylines are an indicator of how many places forming a matching combination can be paid out. With many of the slots that have multiple paylines, you can choose how many of them you want to be on while you play. If there is such an option, the size of the minimum bet you will have to place will also depend on it. The bet must be in accordance with your virtual balance or, if you are playing with real money, to the budget you have set.

  7. 4️⃣ Click on the “Spin” Button
  8. Once you go through all the above steps, you can press the "Spin" button. If you are not one of those players who want to press the button manually all the time, you can turn on the Autoplay function. This way, you have the chance to try out a bunch of free slots, evaluate their quality, and if you like one enough to be sure you want to play it for real money, do so once you are convinced of your judgment.

Play Free Slots with Free Spins Bonuses

Free spins? Yes, you read that right. But no, free slots and free spins are not the same things. Before proceeding, it is important to clarify what means to avoid any confusion. Essentially, free spins are a type of bonus bet that the casino gives you in exchange for a deposit. Free spins are most often found as part of the Welcome Offer but can also be part of other promotions. This bonus does not enter your account balance as money and is usually tied to wagering requirements and sometimes to a specific slot machine. Until you use up the free spins, you play without having to place a bet.

However, the term "free spins" has another meaning. It is related to the mechanics of the slot machine and the bonus features it has. They are activated differently depending on the game and the feature they come with. One of the most common bonus rounds is the so-called "Free Spins" feature. When activated, you get a certain number of spins, the spending of which you do not place a bet. This free spin type can be obtained only from the game itself.

Where do free slots fit into this equation? As we have highlighted, free slots are demo versions of real money games. The only difference is that you do not put your money on the line, but instead, you play with a credited amount of virtual fictitious money. Therefore, every spin in the free game is considered a free spin as you do not place a real money bet. Logically, if you land a winning combination, it will not be a real money prize. If you are in search of free slots to play for fun, you can find plenty of them on our site. In case you like a free slot and want to try it for real money, take a look at the next three sections where we reveal three casinos whose bonus offers include free spins.

MrPlay – 100 Free Spins + 100% Up to €200 Welcome Bonus

If you sign up at MrPlay and make a first deposit of at least €10, you will be eligible for claiming the Welcome Offer of the moustachioed casino. On your first deposit, you will receive 20 free spins and a matching amount of the sum as long as it does not exceed €200. Over the second and third deposits of €20, 80 free spins will come your way.

Ice Casino – 270 Free Spins + Up to €1,500

Ice Casino’s Welcome Offer is divided into four stages. The minimum amount you should deposit to be eligible is €10. Each of the four stages gives a different percentage of what you have deposited in the casino, as well as a different number of free spins tied to five slot machines. The maximum amount of cash you can get is €1,500 and the free spins are 270.

NetBet - Up to 500 Free Spins Welcome Bonus

Making a minimum deposit of €10 or more after registering at NetBet, will give you the chance to claim the Welcome Offer. After your first qualifying deposit is a fact, you can use the bonus code ‘NBWELCOME500’ to receive 50 free spins. Over the next six days, you may grab additional 450 free spins but the maximum number you could get per day is 75.

How Do We Rate Casinos for Free Slot Games

We at Irish Online Casino, are a team of experts who know the online gambling industry in Ireland in detail. We focus our efforts on testing and writing reviews of games and casino sites so that you can find a good casino that meets your requirements as quickly as possible. When we research a casino, we take many factors into consideration to determine if it is a reliable or a dodgy one. Take a look at the following list to see which are the most important features for rating casinos.

  1. Casino Licensing
  2. This is the most important factor. The lack of a licence is not even up for discussion, and if you come across such a casino, a red light should immediately go off in your head. When the operator is licensed (the UK Gambling Commission, Malta Gaming Authority, Curacao eGaming, etc.), it means that it is subject to regulation and follows certain rules in order not to have its licence revoked. Irish casinos must also hold a valid Irish gaming licence under the Betting Act of 2015.

  3. Free Slots Variety
  4. The variety of slots on gambling sites is the topic that excites players the most. No one wants to sign up at a casino that does not have quality games in its collection. However, it is not only important how many titles there are in the catalogue, but also how many of them have demo versions that you can test on the respective site. At every casino, free slots are the best way to learn everything you need about slots you have an eye on without risking your money.

  5. Slot Providers
  6. This factor will probably be better understood by experienced players. It is directly related to the variety of slots, which depends on the software companies with which the casino has a contract. Agreements with the best providers in the industry such as Microgaming, Big Time Gaming, and Blueprint Gaming are a must-have because they guarantee that certain games will be part of the casino's library. In this case, they are as follows: Mega Moolah slots, Megaways slots, and Jackpot King slots.

  7. Bonuses and Promotions
  8. Apart from the variety of slots, the other thing that excites players the most is the bonuses. For this reason, many of them fall prey to welcome bonuses with unclear rules offered by shady casinos. Bonuses and promotions are one of the main evaluation criteria when looking at a casino. They should have clear conditions under which they are given so that the player can decide whether he wants to claim the bonus.

  9. Customer Support
  10. Not sure what game to start with? Encountering registration issues? Having trouble paying? You can get the answer to these and any other questions from the casino's customer support team. Usually, you can communicate with them by email or live chat, and in some cases by phone. The level of customer service is extremely important because these are the people who should help you in solving various problems that may arise during your gambling experience.

  11. Mobile Capability
  12. Considering the fact that we are used to doing everything through our phones, the mobile capabilities of casinos are essential. Gambling sites must be 100% optimized for mobile use by both iOS and Android users. This is possible by implementing the HTML 5 technology in the codes of the sites. Some casinos even go a step further by developing mobile apps for an even better experience.

Free No Download Slots Casinos by Category

Here we categorize the casinos offering free no-download slots. Some have the best selections of slot games, others specialize in collecting certain kinds of slot machines, and others offer some of the best promotions that can be applied to such types of games. Have a look at the table to find out what to expect at which casino.

With such variety, there is no doubt that all game styles, genres, and themes are covered. If you want to try a non-slot machine game, the platform offers many other options.

Most Popular Free Slot Machine Games Providers

Free slot machines are practically the same games you can play in real money casinos. Certified casino software developers provide free slots to play not only in Ireland but all over the world.

Some brands have successfully proven themselves and established their name in the global iGaming market. Read on to find out which are the most popular free slot development studios.

Currently, the brand has over 290 slots such as Book of Dead, Reactoonz, and Fire Joker.
