Online real money slots are the heart of casino games. It's an understatement to say a slot game collection determines the future of an online casino. To cover every player's needs, the number of slot games at the best online casinos in Ireland can add up to several thousand these days.
However, having too many options often leads to confusion. Some of you might wonder, "Which slots should I play for real money?" or "Are there any ways to find the best real money slots for me?".
There are many elements to consider when choosing the best slots to play online for real money. So, here are the key factors you should know about real money online slots:
Let us break down each element for you below.
RTP stands for Return to Players in online gambling. It indicates how much an online real money slot pays out to players from all the money bet on the game.
Theoretically, you are expected to lose 3% of your money in the long run if you keep playing on an online slot whose RTP is 97%. However, it does not mean you cannot win big money by playing online slots if you understand the concept of probability and volatility.
Of course, the higher the RTP of an online slot, the more winnings you can expect in the long term.
Volatility in online real money slots is like a game's way of saying how often and how much it will give winnings. Imagine a slot game is like a treasure chest. If a game has high volatility, it's like a treasure chest that doesn't open very often, but when it does, there's a chance of finding a lot of treasure there.
Let's say there are two online slot games for real money whose RTPs are the same at 97%, but one has high volatility while the other has low volatility. The high volatility slot pays less often, but when it does, you're likely to hit a big win. On the other hand, the low volatility slot pays more often but in small amounts.
By and large, these two games pay out in different frequencies and sizes but return the same amount of money to you in the long run.
Playing slots with high volatility might make you feel like you never win because of their low payout frequency, but it comes with the absolute excitement of potentially winning a fortune. On the contrary, real money slots with low volatility would be a better option if you want to keep it safe and enjoy the experience of playing slots for a long time.
In essence, slot bonus rounds are special game rounds within a slot machine that activate at certain moments during your play.
These bonus games might be triggered by landing scatter symbols or activated randomly. Sometimes, you can initiate them at any point for a fee.
Free spins are spins that don't require you to use your balance. These are commonly found in numerous online slots for real money. To access them, you typically need to land a set of special symbols in a single spin.
Engaging in online slots with real money can be expensive, especially when luck isn't on your side. Free spins offer an opportunity to play and potentially win without any cost. Additionally, some video slots provide opportunities to gain extra free spins while using your current free spins, leading to an extended series of cost-free gaming rounds.
There are a multitude of game studios that produce real money slot games online. They strive to add something unique to their products to stand out. Some of them put efforts into creating high-quality animation and sounds, while others specialise in developing new features to make the experience exceptional.
Knowing what game studios have what slot styles helps you select the best game studio that suits your taste.
Slot machines, once known as one-armed bandits, have evolved with advanced technology, offering fun and exciting online gaming today. Over 70% of casino games online are now slot games, available on online gambling sites and mobile apps.
Online slots attract players with the potential to win big from small bets. Their entertaining gameplay also adds to their appeal. The UK is home to a vast array of online slots from numerous developers, featured on top slot sites.
For those overwhelmed by the choices, our guide highlights the best UK online slot sites. Easily compare the best UK online casinos offering real money slots, including their game variety, payout rates, and top game providers like NetEnt and Microgaming.
Their simplicity and the chance to win big - often in the millions - make online slots hugely popular in the UK. Additionally, many casinos offer free spins as incentives, adding to their attractiveness.
Online slots are user-friendly and convenient, playable on mobile devices anywhere. They often feature higher jackpots than physical machines and progressive jackpots that can grow to significant amounts.
With high Return to Player (RTP) rates, typically between 94% and 97%, players receive a large proportion of their stakes back over time. Slot tournaments add excitement, with competitors vying for prizes and grand rewards based on their winnings.
Unlike old mechanical machines, modern online slots use software to simulate reel spinning. Wins are based on lining up matching symbols in various patterns. Players can choose how many lines to play, affecting the stake per spin.
Jackpot symbols offer the most significant prizes but are less likely to appear. Many games feature bonus rounds triggered by specific symbols, offering extra challenges or puzzles for additional wins.
Online slots function similarly to physical machines but are controlled by software and display results on a screen. They use Random Number Generators (RNG) to ensure fair play, with independent audits required for legality in the UK.
In gameplay, you select your stake, wager amount per pay line, and the number of paylines. Options like autoplay allow for continuous spinning without manual input. Wins are automatically added to your balance, which you can choose to either gamble with or withdraw.
Online slots have diversified significantly, offering a variety of gameplay styles despite all being governed by Random Number Generators. In the United Kingdom, top online slot casinos often prioritise these games, presenting a vast selection that includes 3D slots, video slots, and those themed around popular media.

If there’s one thing that online casinos do well, it’s promotions and bonuses - especially when it comes to online slots.
Online slots are very, very popular with players, which is why the online casino sites are keen to offer lucrative bonuses to attract new players and run regular promotions to keep players loyal.
Here is a rundown of the most common types of bonuses and promotions for online slots that you can find out there and where to find them.
The welcome bonus is only open to new players that register at an online casino and players can only claim it once. A deposit match bonus is a welcome offer that gives new players a bonus that matches (or sometimes doubles) the amount of their first deposit (or first two or three deposits).
One of the best-matched deposit bonuses available at an online slots site at the moment is with The Grand Ivy which offers a 100% match bonus up to the value of £1500 (spread over the first three deposits), plus 100 bonus spins.
As online casinos compete more and more fiercely with each other to get new customers, no-deposit welcome bonuses are becoming increasingly common. As the title suggests, these welcome offers don’t require any deposit, you simply need to register for the site and verify your ID to qualify.
The best no-deposit welcome bonus at the moment is available at 888casino where they give you £88 worth of free play credits.
Free spins can be offered as part of a welcome bonus or as an offer to existing customers. There is no deposit needed, but they usually have wagering requirements attached to them to release any winnings.
In other words, you usually need to wager between 20 and 50 times the bonus amount before you can withdraw the winnings as cash.
These are sometimes referred to as no wager free spins and they are the best time of “free spin” as you don’t need to meet any wagering requirements. This means that any money you win by using the bonus spins is yours to keep and you can withdraw it right away.
Reload bonuses are bonus spins or deposit match bonuses that are given to you when you reload your account, i.e. make another cash deposit into your casino balance. Reload bonuses are usually run as occasional special offers that are time-limited, rather than ongoing promotions.
Slots tournaments are fun promotions that have a set prize pool to be distributed amongst players that score highly on a leaderboard. During the set time of the tournament, players score points for money won or money staked. The prizes are usually heavily weighted towards the top one, two, or three players.
William Hill, Bet Victor and Virgin Casino are recognised as the top 3 casinos for online slots tournaments.
Irish slots casinos are likely to feature games from a wide range of providers. Some companies are better known than others, but even smaller developers can produce fantastic slot games.
With that in mind, here are 10 of the most popular slot providers at Irish online casinos right now:
Microgaming: Claiming to have developed the world's first true online casino software in 1994, Microgaming has long been one of the industry's most important companies. Microgaming was also a pioneer in the launch of the first mobile casinos, having launched its software in 2004.
NetEnt: Swedish studio NetEnt has been one of the most popular slot providers in the world for many years. Founded in 1996, NetEnt produces all types of casino games but has a strong focus on slots. Over 200 online slots have been released on to the market by NetEnt so far.
IGT: International Game Technology is one of the best known casino game providers in the world, with a long and proud history of slot development. IGT has been around for decades but the release of a new game from this slot provider still provokes a lot of excitement.
Novomatic: A range of video slot classics are available from Novomatic, with Book of Ra, Sizzling Hot and Lucky Lady's Charm some of the company's biggest hits to date.
Playtech: Founded in 1999, Playtech is now one of the most popular slot providers in the world. At the end of 2019, Playtech launched an industry-first, with its Live Slots potentially offering a glimpse of the future of online casinos. Age of the Gods: King of Olympus is one of the best Playtech slots that is available to play at online casino sites in Ireland.
Play'n GO: Specialising in high variance slot games, Play'n GO has grown into one of the most popular slot providers around over the course of recent years. Play'n GO titles include the huge Rich Wilde series, which has spawned a wide variety of imitations across the industry.
Pragmatic Play: A leading provider of slot game content for online casinos, Pragmatic Play hits include Wolf Gold and Dog House. Despite only being founded in 2015, Pragmatic Play games can be found at most of the top online slots sites in Ireland, with the company continuing to grow.
Yggdrasil: Slots from Yggdrasil are known for their incredible design, with progressive jackpot games among those produced by the developer. Valley of the Gods is one of the top online slot games to have been released by Yggdrasil, with Holmes and the Stolen Stones up there too.
Quickspin: Another Swedish studio operating at the top of the online slots industry is Quickspin, a company that focuses on quality rather than quantity. This means that Quickspin does not release nearly as many new slot games as other providers, but they are always worth trying.
Realistic Games: Last on our list of the best online slots providers is Realistic Games, a leading casino content developer. Realistic Games is the company behind the hilarious Hot Cross Bunnies game, with the UK-based firm also producing games like Take Note.
Although online slots rely on random chance, there are some things you can do to try and increase your chance of winning or at least limit your losses.
Check out the following list of tips to help you get the best value for money when playing online sites in the UK.
The best way to make a bit of extra money when playing slots is to find the best welcome bonuses and make sure you claim them. Whether it’s a deposit match bonus or free spins, it’s always worth trying to get hold of this free cash that is offered to new players.
Just be aware that most welcome bonuses have wagering requirements attached, which means you have to bet a certain amount on the site before the bonus is turned into cash. Look for the welcome bonuses that have no or few wagering requirements. No deposit bonuses are good too, as you don’t need to spend a penny of your own money to get a chance of making some winnings.
This is a more practical tip that you need to implement before and during playing. First, you need to decide how much you are willing to lose in any one session. This is not necessarily the total amount you can afford to lose, it could be the amount that is going to really annoy you and make you want to chase your losses.
Write down the limit and keep it in mind while you are playing. If you reach the stop-loss limit, let’s say £30, then you log off straight away and stop playing. You can decide how long to stop for, whether it’s a ten-minute break or stop for the day, or even week. If you stick to this strategy it will stop you from chasing your losses and should limit the amount you lose overall.
Similar to the stop-loss strategy laid out above, the stop-win is exactly the same, but you set a limit for the amount of profit you’re in. When you get to that maximum limit you stop and take a break - ten minutes, one hour, a day - whatever you decide.
The reason for setting a stop-win limit is that it’s all too easy to feel like you’re invincible and can’t lose. Many people will then start playing at higher stakes and quickly lose all their winnings. You need to avoid this at all costs.
Another way to limit your losses and maximise your winnings is to set a strict time limit for playing the slots. It’s easy to get carried away and play for hours upon end, but this can possibly turn into irresponsible gambling if you’re not careful. Set an alarm on your watch or phone for 30 minutes, or however long you’re willing to play, then be disciplined enough to stop when it goes off - whether you’re winning or losing.
Use our lists of high RTP slots and slots sites above to help you choose games that offer the best return on your money. This will help to make your bankroll last a bit longer and give you more chance of hitting some big wins.
This applies to most slots sites - you cannot win the maximum amount of the progressive jackpot if you don’t play at the full stake. In other words, if you only play one winline when there are ten available and you hit the jackpot, you’ll only win 10% of it. Not everyone is aware of this fact.
