Venturing into the world of the online gambling industry for the first time can be daunting, especially when you're not sure which online slots site you should go for. We're here to help.

At Irishluck, we look at the best online casino slots for you, breaking down everything you need to know, such as RTP, progressive jackpots, slot volatility, and other important features. We also review slots sites online and list plenty for you to choose from.

Slot Sites Online for Real Money Money Slots

Our method of ranking a slot site covers several crucial factors to guarantee players a safe, secure, entertaining gaming session. Here is what we prioritise when recommending the best slot site:

  1. A diverse collection of the best slots: We wouldn't advocate settling for a casino with limited slots online. A great source of popular slots from premier software providers, sometimes even unique in-house software, is what we go for. Bonus points if they allow 'demo' or 'practise' modes for slots.

  2. Generous bonuses and welcome offers: We look at online casinos that offer worthwhile promotions from free spins, match deposit bonuses, no deposit bonuses and more. However, the first type of bonus we look at is a lucrative sign-up bonus. Fair bonus terms & conditions which are attainable are a big positive too.

  3. Quick and easy payouts: No one enjoys delays, especially when it comes to cashing out winnings from real money slots or a bonus. That's why we endorse online casinos with swift payouts, quick processing times, fast KYC processes, and various payment methods.

How to Win at Online Slots

As we have mentioned, to win a round during a slot game, a player will need to land winning combinations by hitting consecutive identical symbols across a payline. Typically, these symbols need to land from the leftmost reel to the right to trigger a win, but some unique slots pay out winnings each way, i.e., whether the symbols line up from the left or the right.

A look at a game's paytable will tell you how many of each symbol you will need to trigger winning combinations and how much you will win when you land them. In a classic five-reel slot game, you will see that the biggest prizes come when you hit five symbols, while the smallest comes from 2 or 3 in a row.

Most slot games offer players the opportunity of playing with more than one active line, some offering up to 100 lines. So, to win, you will need to hit matching symbols on one or more active lines.

Online Casino Slot Variations

As mentioned earlier, classic slot games have come a long way from the early days of fruit machines. The shift from traditional land-based slot machines to the internet's digital space spelt a new era for slot games. With online slots, slot enthusiasts no longer have to travel to the nearest casino, arcade, or other venues in order to access and play their favourite slot games. 

Players can play real money online slots anytime and anywhere with just a few clicks on their mobile or desktop devices. Beyond the flexibility and increased convenience of online slot games, another advantage the best online slots have brought about is the availability of different slot variations. With slot developers pushing changes and innovation, today's slot games come in various shapes and sizes. The most common types of slots that are available to gamblers online include:

Classic Slots

The classic slot games are basically throwback online slots that often mimic the games of a bygone era that you would usually find in bars, arcades, and casino floors before the invention of video slot machines. Like the games of that time, classic online slots usually come with lines and rows and, by extension, fewer paylines.

 

Much like the old one-armed bandit machines, classic online casino slots usually have very simple designs, gameplay, and features. Usually, you will find little to no bonus features when you play games. 


While this may sound dull, these slots are designed to remove all the noise that usually comes with modern slot titles, allowing players to enjoy simplicity in gameplay. As a result, classic slot games are the best fit for Irish players who prefer an uncomplicated game with simple gameplay and little to no distracting features.

Video Slots

Video slots are undoubtedly the most popular and the most sought-after type of slot game, evident by the sheer number of options available to players online. You'll notice the majority of slots available at the best slot sites are video slots.


These games usually come with great graphics, designs, and soundtracks, alongside exciting features like wilds, scatters, bonus games, free spins, among others, to keep players entertained for hours on end. Unlike their classic counterparts, video slots can come with five, seven, and sometimes nine or more reels, which naturally brings players more paylines and more ways to win.

icon of three seven in green, white and orange color

Megaways Slots

Another popular and innovative type of slot taking Ireland and the world by storm in recent years is Megaways slots. These slots feature different mechanics from traditional ones, usually having fixed numbers of reels and pay lines. 


Instead, Megaways slots have a random reel modifier that usually changes the layout and the number of symbols that appear with every spin. This system provides players with hundreds of thousands of possible ways to win.

icon of three seven in green, white and orange color

Branded Slots

The improvements in design and themes to slot games over the years have given players a more immersive gaming experience; leading to the development of branded slot games, games attached to famous movies, TV shows, bands, game shows, or any other iconic brands of any kind. 


These games feature themes, characters, and even clips related to popular culture to appeal to the fans of the brands. Unsurprisingly, branded slots became popular amongst slot enthusiasts, and this trend has accelerated over the years.

3D Slots

The advances in technology have led to innovations in every industry across the globe, and the iGaming industry is no exception. Among the most innovative developments that have shown up in the iGaming industry in recent years is the advent of 3D slots, a prevalent variety of slot games.


3D slots are the same as video slots in gameplay and game features. The only difference is that 3D slots come with much better graphics, animation, and design than what you will find playing regular video slots. 3D slots also usually come with a much stronger narrative and storyline attached to the game for a more immersive overall gaming experience for players.

icon of three seven in green, white and orange color

Jackpot Slots

Jackpot slot games offer players the chance to win life-changing sums of money from just a simple spin during the game. There is often confusion about how jackpots in slots work, and this is because there are two types of jackpot slot games, namely standard and progressive jackpot slots.


  • Standard jackpot slot games: The provider or the online slots websites set a massive fixed jackpot winnable when a player hits the winning combination. While standard jackpot slot games usually feature impressive amounts, their payouts are generally smaller than progressive jackpot slots.

  • Progressive jackpot slot games: Progressive jackpot slot games offer much bigger jackpots. This game takes a very small part of every stake made by players to contribute to the pot. The pot size will naturally keep increasing as more players place bets on the game. These jackpot slots are usually linked to other games to amass even bigger payouts.

How Online Slots Work

One indisputable fact about online slots is that they are the simplest online casino games available to players online. While each slot game will have special themes, unique gameplay, and various features, most slot games share the same basic framework and working principle. 

You place your bet, press the spin button, and then wait to see if you get a win after the reels stop spinning. There is little to no skill involved, and it primarily depends on players' luck.

Slot Setup

Slot games are set up on a 'reels and rows' layout, where various symbols in the game will be arranged; the number of reels and rows will usually depend on the type of game design. Classic slots usually have three reels and three rows, i.e., a 3x3 layout, but some special classics feature up to 5 reels. On the other hand, video slots usually feature five reels and three rows, resulting in a standard 3x5 layout. There are also many unique video slots, which come with more reels or rows than the standard, resulting in 4x5 slots, 5x5 slots, and more.

Paylines Explained

Slot games work because different symbols are arranged on the reels and rows of the game's layout.  Once a player presses the spin button, the slot's reels will be put into motion, thereby spinning the various reels available in the game. When the reel stops spinning, the arrangement of the symbols will change from what it was before the spin.

The slot pay line is a line on the layout setup of slot machines where winning combinations are evaluated. If three or more or, in some cases, two or more similar symbols land on an active pay line, a player would potentially trigger a winning combination, which will be paid according to the paytable. 

Due to their standard 3x3 layout, classic slots usually have one, three, or five, up to only nine pay lines. Whereas, video slots usually have 9, 15, 25, or as many as 1024 different pay lines. The more pay lines a slot game has, the more winning combinations could be potentially triggered and the better players' winning chances.

The Random Number Generator

The basics of online slots are not very different from how they used to work when the first slot machines came onto the scene. You place your wager, spin the reels, and wait for the reels to stop spinning to see if you manage to land a winning combo. However, back then, the randomness of the spinning reels was done mechanically.

Naturally, this is no longer the case, as random number generators now generate the outcome of every spin in slot games. So, what exactly is a random number generator, and how does it work? 

In the background of every slot game is the random number generator, an algorithm that constantly generates random numbers. The RNG algorithm constantly selects random numbers every millisecond, usually a value between 0 and 4 billion (approximately). 

These random numbers are connected to a different outcome on the slot machine's reels. The random number that the RNG algorithm generates when you press the spin button determines the outcome.

In simpler terms, the process is:

  • Casino enthusiasts press the spin button, and the RNG algorithm automatically generates a random number.

  • The mathematical module in the game translates the random number and determines where the reels should stop.

  • The reels stop and symbols are arranged according to the outcome the random number brought.

Interestingly, the random number generator doesn't just work with online slot machines. The software is employed in every online slot game, including the likes of online blackjack, online baccarat, online craps, online poker, and nearly every online casino game. The only exception is live casino games, which are played live.

Return to Player (RTP)

One of the key concepts you need to familiarize yourself with when playing slot games online is RTP, which stands for return to player percentage. The RTP of a slot machine refers to the percentage of the cash stake a particular slot will return to you over an extended playing period. It essentially refers to the house edge. 

For example, if a slot game has a 96.5% published RTP, players should expect to receive back €96.50 returns for every €100 they wager on the game. You should note that RTP is a theoretical value calculated over millions of spins. It gives a rough estimate of the average return players can expect from a slot game, not what they will find during every playing session. As a result, players will either profit or lose each playing session.

This is why playing high RTP slot games is a good idea for slot enthusiasts, as the games give them a statistically better chance of minimizing their losses over time. Typically, the average RTP for most slot games is around the 96% mark. However, you will also find those with RTP as high as 98% or 99%.

Volatility/Variance

Another key concept you must not overlook where the best online slots are concerned is the volatility of the game, also known as the "variance."  Each slot will have a class in terms of volatility, usually low, medium, or high. Low-volatility slots games mean you can expect regular wins but in low amounts. Whereas high volatile games mean that you will not win very often, the winnings are usually quite big when you do. 

Features in Slot Games

Many people find the "bet, spin, repeat" pattern of slot games quite boring, unlike other casino games and table games, which tend to have more interesting gameplay. As a result, slot developers have introduced many innovative features to spice up the seemingly boring gameplay of slot machines. 

These extra features not only make the gameplay of online slot machines a lot more exciting but also usually improve players' winning chances. Here are some of the features to look forward to when playing slot games:

Wilds

This is the most common feature you will find playing slots online. Like how a joker card works in card games, wild symbols are extra symbols in slots that substitute for other symbols on the reels and help players turn a losing symbol combination into winnings. 

For example, if you hit two matching symbols and a wild symbol on the next reel, the wild symbol will act as the third symbol required to trigger a winning combo. Innovative online slot developers have tweaked the wilds feature and invented different kinds of wilds features, all of which usually have extra features in addition to substituting for symbols. Some of the most popular ones include:

  • Expanding Wilds

  • Sticky Wilds

  • Shifting Wilds

  • Random Wilds

  • Stacked Wilds

Scatters

Typically, winning combinations in slot games are triggered by landing identical symbols aligned next to each other across an active payline. This is not the case with the scatters feature. 

With the scatters feature, the appearance of three, four, or five of a specific symbol (usually called the scatter symbol) in any position on the reels will generate a usually generous payout. In addition to paying out scatter winnings, scatter symbols are also known to be responsible for triggering free spins rounds or bonus games in slots.

Free Spins

The free spins feature is a pretty form of bonus that you will find in many online slot games. As the name implies, the free spins no deposit feature allows players to automatically play slots with a series of spins at no charge. 

Free spins are usually triggered when a player lands three or more scatter symbols, the number of symbols determining the free spins received. In most cases, free spins are usually recurring, so you will have the opportunity to multiply your free spins with new scatters.

Gamble Feature

After every winning spin, some real money online slots will offer a gamble feature to players, where you will have a chance to double your winnings or significantly increase them even more with this feature.

The gamble game is usually based on guessing the colour or suit of playing cards or tossing a coin, though this varies from slot to slot. While the gamble feature can help you increase winnings significantly, it can also lead to a total loss if you make an incorrect prediction.

Bonus Rounds

Aside from free spins, the best online slots also come with exciting bonus rounds separate from the main game to allow players to enjoy even more winnings. A few of the most common bonus game types you can expect to see when you play slots online include:

  • Jackpot Bonus: Gives players a shot at winning a slot game’s top prize.

  • Pick a Reward: This bonus round gives players a blind chance at winning rewards by selecting symbols that they think are hiding rewards.

  • Bonus Wheel: This allows players to enjoy rewards by spinning a wheel.

The idea of a 'hot' or 'cold' slot is more myth than reality. In truth, each spin is independent and the outcome is determined by random number generators. Instead of chasing fallacies, I recommend focusing on informed gameplay. Play wisely and use strategy to ensure success and keep your pockets safe. The only truly 'hot' thing about online slots is the adrenaline rush they provide.

Free Slots vs. Real Money Slots

One of the biggest advantages online slot sites have over their land-based brick-and-mortar counterparts is the availability of demos and free games. Typically, you have to play real money slots when you visit land-based casinos. There is no “try before you buy” deal when playing at brick-and-mortar casinos.

However, this is not the case at online casinos and online slots sites. Many game developers and slots sites online offer demo versions to play online slots for free without spending their cash. This feature is a great way for players to test out different slot games and identify the ones worth their time. 

Players can also use demo-free slots to understand each game's theme, design, sounds, and other features before playing with real money. Beyond getting familiar with a slot, many experienced slot enthusiasts play free online slots in demo mode to have a first-hand experience of how a slot game works. 

Doing this helps them learn about its gameplay, RTP & volatility, betting limits, potential payouts, bonus features, and other relevant features. Some would even use the demo mode to devise a strategy when they start playing the same slot for real money. 

That being said, when it comes to playing online casino games, you can either play for free via the demo mode or directly head over to an online casino site to play for real money. However, it is always advisable to try out the free demo version for a while to get familiar with any slot game before going ahead to play it for real money.

Best Online Slot Providers

Unlike traditional land-based casinos, online casinos and online slots sites are not limited and can host as many games as possible. This has led to the online industry being blessed with a wealth of extremely talented software providers who have developed all the slot games you will find online today. 

These software providers compete to create the most exciting games every year, resulting in many innovative features in the slot industry. Many companies have managed to make a mark in the industry, known synonymously for the best online slots. With that in mind, here are some of the most popular providers of online slot titles at the moment:

Playtech

Another pioneer of online casino gaming, especially the best online slots that remains a giant in today's iGaming industry is Playtech, a software provider that opened its doors in 1999. With more than 170 global licensees in over 30 jurisdictions, Playtech has a global footprint, making it among the most popular slot games providers. Playtech claims to be the world's largest online gaming software provider. 

This statement is not far from the truth, as it provides a massive collection of software for online casinos, online slots sites, poker rooms, and bingo rooms.

It started as a company that built physical slot machines for brick-and-mortar casinos, which it still does to date. 

When it finally decided to extend its influence into online gaming, IGT unsurprisingly made a successful transition, becoming a household name for slot games, be it online slot machines or physical ones. With decades of experience in the industry, IGT has managed to amass an impressive collection of innovative and quality slot titles, including all sorts of varieties, especially branded slots. In IGT's slot collection, standout titles include Cleopatra, Davinci Diamonds, Wolf Run, Wheel of Fortune, Pharaoh's Fortune.

Slots Online Bonuses and Free Spins

One of the biggest advantages of playing slots and other casino games online is the excitement of bonus funds at the players' disposal. The best online slots sites will offer their users different incentives, most commonly as welcome bonus offers like no deposit bonuses, deposit match bonus offers, free spins, and others. In order to stand out, an online slot casino needs to captivate players with its welcome bonus. However, since these bonuses differ between casinos, we recommend looking at our casino reviews to help pinpoint the most appealing promotions.

Some common bonuses to play slots online include:

  • Match Deposit Bonuses: An online slot casino will incentivise new players to register by offering to match their first deposit with a specified percentage, usually ranging from 50%, 100%, 200%, and, if you're lucky, even 500%. This welcome bonus usually includes additional free spins or could be spread out over multiple first deposits offering a lucrative package.

  • Reload Bonuses: A great slots site will offer reload bonuses as a sign of appreciation for loyal players after the initial welcome bonus package. These could be in the form of free spins or a reduced match deposit bonus, for example, a 50% match deposit bonus.

  • VIP Promotions: These promotions are a host of VIP schemes with exclusive perks. VIP bonuses come in different forms depending on what the online slot casino offers; however, the most common include free spins, cashback, no wagering bonuses, exclusive tournaments for progressive jackpots, and other privileges. The more you play, the higher you go up the ranks, and the more profitable these bonuses would be. 

  • No Deposit Bonuses: This type of bonus is a fan favourite at a slot casino site. As the name says, a no-deposit bonus is where you can claim a bonus without making a deposit. These bonuses can be free funds which you can use to play real money slots or could also be in the form of free spins. While no deposit bonuses might be a modest sum and come with strict play-through requirements, there are still valuable to come across since they're free.

Common Slots Bonus Wagering Requirements and Terms & Conditions

Many casinos offer their players different promotions through bonus funds to enjoy their favourite games. It is worth noting that a slots site is in the business of online gambling for profit; offering free money with no conditions will be a loss for them. As a result, attached to online slots casino bonuses are criteria which must be met in order to claim, known as wagering requirements and terms & conditions.

So, whether it is free bonus spins winnings or bonus money, you will need to meet the wagering requirement on that bonus amount a certain number of times before you can be eligible for a withdrawal. Wagers can be anywhere between 20x and 50x the bonus amount. 

For example, if you receive a €100 match deposit bonus and a wagering requirement of 20x, you would need to wager a total of €2000 (20 x €100) before withdrawing to your cash balance. So ensure you inspect the terms, as the wagering requirement might only apply to the bonus but sometimes can include the original deposit too.

On the other hand, free spins bonuses will have wagering requirements applied to the earnings. You would also occasionally find bonuses with low or no wagering requirements, which are commonly reserved for loyalty or VIP bonuses.

Some other things you should look out for in the bonus terms & conditions are:

  • Withdrawal limits: Bonuses might set a cap for earnings, primarily for no-deposit bonuses. Common limits are €50 - €100.

  • Wagering contributions: See which games contribute to the wagering requirement. Most often, slot games will contribute 100%, while lower-house edge games like roulette might only contribute 10-20% of the wagering requirement.

  • Game limits: Not all game titles might qualify for bonus use. Ensure you check which slots online apply for your free spins in the fine print.

  • Maximum bets: A key thing to check in the terms is if there is a cap on bets when using your bonus, as breaching the maximum stake could void your winnings.

Mobile Slots

In today's modern era, many people now prefer to play slot games on their mobile smartphones and tablets from just about anywhere rather than sitting in front of a laptop or desktop computer. Due to this, mobile optimisation has become a necessity and not a luxury when playing slot games online.

As a result, most slot game providers implement a mobile-first approach when developing new slot games. Nearly all the new slot titles are mobile-compatible and playable on Android, iOS, Windows, and other mobile platforms. 

Even most old-school classics made before the development of mobile gameplay have been updated and made available for mobile casinos online. This means you can access mobile slots and play online from the comfort of your mobile device's web browser or a casino app. Check out some of our recommendations below.
