Slots
Your first steps into the realm of online slots. This guide will teach you all you need to know about slots, from the very basic terms to the master tips you will want to hear. Find out all about the different types of slot games, the jackpots you can win, and the meaning of the symbols on the reels. Enjoy playing free slots games and find the best online casinos with real money slot games, rated by our team of casino experts.

Overview

The goal of every casino game is to be as popular as slots. Slots are the Apple of gambling. They are synonymous with the word gambling itself, and their popularity is unmatched, unchallenged and most likely eternal. Gambling, online or conventional, would be a shelf of itself without slots.

Slots combine multiple virtues that punters adore. The latter include simplicity, fun graphics, potentially huge winnings, and various stake sizes. They have something for everyone, and they will not leave you wanting. Are you a high roller or a casual looking to have fun with a spare €20 bill? Slots have precisely the type of game that you are looking for, and you will have a hard time finding an Irish casino that falls short when it comes to providing slots.

What Makes Real Money Slots So Attractive

Products that retain the respect and admiration of consumers have to be built on solid foundations. This is something that slots are acutely aware of. They have decided to stick to a simplistic formula that removes overly complicated rules and sticks to a format that allows anyone to jump in whenever they feel like it.

All you have to do is put some money into the machine, click spin and hope for the best. Your chances of winning are the same as those of the person next to you. This lack of generally accepted strategies and the fact that you do not need particular skills to win have made slots the favourite of the masses the world over.

However, the pros do not end there. When you combine this simplistic design with superb graphics, jaw-dropping effects, and incredibly entertaining and engaging features, you produce game-to-end all-games. The modern real money slot is a masterpiece akin to video games that appeal to the fun-hungry masses.

Lastly, slots do not discriminate. They accept players of all calibres and wallet sizes. Moreover, they offer insane rewards for even the smallest of bets. This allows players that start with a humble €10 or €20 to reach three or even four-figure sums. Note that penny betting is something largely exclusive to slots, as blackjack or roulette sets higher betting limits and limits wins accordingly.

The Backstage: What Makes Real Money Slots Tick?

When you sit down at a generic slot, you are bombarded with an array of colours and animations. Such a form of 'eye candy' is meant to make the games more invigorating and fun. But this eye candy is just a front. The real magic lies deep within the machine, in its chip or algorithm, to be exact.

The basis of Irish real money slots are RNGs (random number generators). These snippets of code prop up the entire machine by determining the random outcome of spins. Each of their results is entirely random and can be triggered when pressing or clicking the spin button. While there are a hundred ways to display the output of the random number generator on reels, the randomness stays pristine and fair.

This mechanic is also the main reason why you do not have to be skilled to play slots. Spinning the reels in a particular pattern or waiting for our spins does nothing to impact the outcome of each individual spin. Your fate is decided as soon as your start your spin, and it cannot be altered. While pursuing the third scatter is a fun mini-game, it does nothing to impact the game itself.

Fairness, RTP, and Volatility

The idea of an algorithm taking charge of your fate and deciding if you win or not is quite scary. However, there are precautions in place to stop casinos from producing unbalanced and unfair games that prevent players from winning.

But who keeps Irish players safe? Who keeps the companies providing games and the casinos themselves in check? Well, those would be dedicated organizations and authorities that specialize in online casinos. The latter includes licensing entities such as the Malta Gambling Authority, which focuses on the fairness and authenticity of their licensed games. Moreover, certain casinos will go out of their way to have their games audited by third parties such as eCOGRA, which reaffirm their fairness and randomness.

You will often come across RTP, which stands for Return to Player and is an essential component of real money slots. This term is related to the percentage of funds that any given game pays back over a certain period of time and the pool of players.

Every casino game, even slots, has a certain house advantage. In the case of slots, this falls to a few percentage points, with the rest being dedicated to RTP. But what does this mean in the real world? Let us get into the brass tax. A slot with a RTP of 96% will pay back €96 for every €100 that are wagered. Note that this is a long-term figure that is based on millions of spins. It does not promise that a player investing €100 will get €96 back.

Remember that two real money slots are not alike, even in terms of RTP. Some subscribe to the idea of frequent small wins, while others make hundreds of spins void and then pay big on one. Naturally, there are some that fall between these two extremes. A slot's approach to RTP is called volatility. Higher volatility requires a larger bankroll but also sets you up for big wins. Lower volatility is, on the other hand, a great choice for longer sessions with smaller budgets, with the drawback being a smaller likelihood of big wins.

Real Money Slot Types: Paylines, Way to Win, and Megaways

The first real money slots were as simple as it gets. There was one payline in the middle, and that's as far as the fun went. Do not get us wrong, punters adored slots, but the limited action also limited fun.

Developers saw this issue and decided to add more paylines to the equation. This saw an evolution to three and five lines, eventually reaching nine and ten. The latter numerical growth also added more ways to win.

A real revolution occurred when conventional mechanical slots evolved into virtual ones. This gave developers the creative freedom to explore various paylines and mechanics that would be either impossible or impractical in real life. These real money slots had paylines numbering 20, 25, 40, 50 and even 100.

The Slot Revolution of Win Ways and Megaways

Your run-of-the-mill 3x5 real money slot has a limited number of paylines, but players always expect more fun and excitement. This demand has forced developers to provide revolutionary concepts pertaining to 'ways to win'. Conventional paylines are replaced by a set of symbols forming a winning combination on neighbouring wheels regardless of their reel positioning. The latter are usually indexed from left to right, with the occasional right-to-left format.

A conventional ex5 grid will have a maximum of 243 ways to win (3x3x3x3x3). This type of slot is incredibly common, and Irish players can partake in hundreds of them. They were remarkable when they first appeared since they brought players completely novel gameplay and a breath of fresh air.

But players are never satisfied with something for long, which is great for the gambling industry. Slots eventually developed 243 and 1024 ways to win, which became the gold standard. When this proved to be stale, developers came up with the idea of 'mega ways', thus giving birth to an area of wins that exceeded six or even seven digits. Modern real money slots bare the fruits of these efforts in the form of millions of ways to win. The culmination of these are mind-boggling wins.

Real Money Slots and Their Bonus Features

Paylines are a great two for one deal. Besides providing you with exciting ways to win thy also offer a chance to grab riveting bonus features of various sorts. While it is true that slots stick to the basic concept of paying during the base game, it is in these bonus features that the real money is. Furthermore, one cannot imagine a modern slot without its bonus rounds.

These integral and potentially lucrative addons come in various forms, including:

  • Free spins
  • Pick and click bonuses
  • Expanding or sticky wilds

The aforementioned bonuses are enriched by various others types of bonuses that together form even more exciting gameplay. The fan favourite among these are free spins, which come in various forms such as:

  • Win multipliers (dynamic or static)
  • More expanding symbols
  • Additional wilds
  • Mysterious symbols

But how do you get free spins? Well, the free spin mode usually has to be triggered by two or more ‘scatters’, so symbols that lead to wins when they appear on the reels regardless of their positioning. These special symbols usually stand out like a sore thumb and you will not be able to miss them.

The next big bonus type are pick and click bonuses, which do exactly what it says on the tin. A player is given various choices, and they need to choose one or more of them to unlock prizes. The latter can come in the form of credits (essentially cash), free spins, win multipliers and so on.

A bonus round can also provide you with expanding and sticky wilds. These take the place of other symbols in win formations (with the exception of scatters). When deployed as a cover for extra positions or retained on reels (for future spins), they drastically up your chances of winning. Note that these might even appear in the base game depending on the variant that you are playing.

The Many Colours of Slots

The beginnings of real money slots were humble, to say the least, but they have come a long way over the last few decades. Modern Irish players can enjoy real money slots that have explored and embraced countless themes covering everything from real-life events, fairy tales, books, and movies to pop culture.

Developers are well aware that the backstory and theme of a slot are just as important to its entertainment value as the gameplay. This mindset has produced slots based on box office hits the likes of Terminator, Robocop, Highlander, The Wizard of Oz, Little Red Riding Hood, Sleeping Beauty etc...

However, none of this would have been possible without the advance of technology and the many tools that it has given designers. These have materialized in the form of fun animations and captivating soundtracks that pull players in and allow them to truly embrace the story at hand. A modern real money slot’s story is not just filler, it is what makes your gambling journey an adventure. Heck, some of them are so well designed that they make free play remarkably fun.

Betting Options

While it is well known that real money slots rank among the simplest online casino games in existence, you ought to dive into their settings and features to safeguard your budget and entertainment factor.

Choosing paylines: Conventional slots allow you to pick the number of paylines that you want to bet on, but this might result in an unsatisfactory result as a winning series of symbols might not be eligible for a payout.

Choosing coin sizes: Every slot has a bet value in the very bottom of the screen. This value indicates how much you are staking per payline. If you choose a coin size of €1, for example, and you have a slot with ten paylines, you are actually wagering €10 per spin. A more efficient handling of your bankroll will require a reduction in coin sizes and not paylines.

Feature purchases: It used to be that bonus features could only be triggered by gameplay, but nowadays you can simply pay to activate them. However, this can cost a very pretty penny, since it can, based on the payout potential, reach 100 times your bet. We advise against this.

Gambling features: While you have the possibility of betting winnings on a coin-toss or guessing a card in some form of mini-game, it is very risky behaviour. Sure, you can double your bet, but why not spend these credits on additional spins?

Max jackpot bets: It is well known that numerous slots with in-game or progressive jackpots increase the probability of a jackpot firing when the bets are maxed out. Have a look at the associated terms to see which games fall into this category. Furthermore, make sure that they appeal to you.

Multi-reel bets: Are you looking for more action at once or simply want to expedite your session? Explore slots that allow for four simultaneous reels featuring either one general bet or multiple reel-specific ones.

Auto Play: AutoPlay is an incredible feature, but it should be used wisely. Limit your losses, decide if the reels should stop when a bonus feature is fired and decide what happens to win spins.

While the individual features might seem daunting, their access is incredibly simplistic. They tend to be neatly packed into menus and on-screen prompts. But be mindful not to rush into things. Always have a gander at the bet value, the euro value, not the number of coins, on hand before spinning. Doing this ensures that your wager is aligned with your dedicated budget.


Why Play

There are multiple reasons why real-money online slots have risen to the top of online gambling in terms of popularity. By moving to software implementations, providers have managed to add all of their artistic flares to a simplistic concept that keeps punters coming back.

When you combine this fact with the following aspects of real money slots, you see exactly why they are worth the praise:

Easy to partake in – Nothing in online gambling is as simple as spinning reels. These are entirely random and their outcome depends on your luck. All you have to do is set a bet, click spin and hope for the best.

A theme for everyone – Few casino games come close to the entertainment value of online slots. Their array of designs, music and gameplay far outnumbers those of other casino games. By creating countless stymes and themes the developers guaranteed that there is something for everyone.

Amazing jackpot potential – Another prized aspect of slots are their progressive and conventional jackpot offers. The latter includes multipliers to the tune of 1000 and progressive jackpot seeds worth up to €1 million, as is the case with Mega Moolah.

Plenty of bonuses – The sheer popularity of real money slots has forced game developers and online venues to provide additional dedicated bonuses. But it is not just free spins and bonus credits that improve your experience, the fact that slots tend to contribute to wagering requirements also pitches in.

We are sure that you now see why Irish players that love online gambling and are on the hunt for their next favourite game tend to flock to online slots.

Tips

While there is no guaranteed way to win at slots, there are certain steps that you can take to enjoy your experience. Remember, slots are a game of chance and should be played exclusively for fun.

Getting Started

There is no better appetizer in online casinos than slots. Their selection of themes is unmatched and their focus on bonus rounds and their representation in casino bonuses make them a solid bet.

1 Know the game before playing for real money.

It is vital that you know the paytbale, bet settings and bonus features of your real money online slot prior to diving into it. This will make for a far more enjoyable experience.

2 Understand the implications of volatility.

The basic idea behind volatility, or the highs and lows of game payouts, is that high-volatility games pay out big but with longer dry-spell periods. Conversely, low-volatility games grant smaller but more frequent payouts.

3 Understand the gameplay implications of RTP.

RTP, or return to player percentage, is a built-in mechanic that essentially lays the foundations for the house edge. If your chosen game has an RTP of 96%, then the house edge is equal to 4%.

4 Rely on reputable developers.

The real money slots that we recommend always come from renown developers. These religiously adhere to international gambling regulations and pride themselves on allowing third-party auditors to look over their payouts and outcomes.

5 Pick a casino with solid slot bonuses.

The popularity of online slots has allowed developers to go wild with both themes and bonuses. Have a look at the sea of possibilities and pick the bonuses that relate to your favourite games. Note that you should always make sure that your financial incentive also comes with low wagering requirements.

Free vs Real Money

Slots Glossary

Slot Types

Beginners might find choosing an online slot to be quite daunting, but the following list of slot types along with their descriptions should help you decide.

Classic Slots

The grandfather of every modern online slot is the humble classic slot. These tend to have 1 to 3 paylines and classic features such as cherry, lemon, bell and bar symbols. Note that the originals did not include free spins or bonus rounds.

Fruit Machines

The origins of fruit machines go back to UK pubs and restaurants, where players used to exchange tokens for prizes. These types of games became to be known as AWP or amusements with prizes.

Video Slots

The era of online slots truly began with video slots and they are not the most common type of real money slot. Their multiple paylines, various coin sizes, bonus features and a selection of themes and art styles offer something for everyone.

3D Slots

3D slots caused a revolution in video slot gaming with their 3D rendered graphics. These allowed for a transition from two dimensional icons to detailed features and in-game animations that made reels feel real.

Virtual Reality Slots

The most exciting entertainment technology of our time are virtual reality headsets and their associated controllers. Casino game developers are aware of this and are investing heavily into developing virtual venues and betting, including spinning reels, in real-time virtual reality.

Megaways Slots

The number of ways that a player can win is determined by the number of paylines that a real money slot offers. More reels mean a higher likelihood of symbols forming winning results. A prime example is the Megaways mechanic that boosts the number of slot wins up to a whopping 117,649.

Progressive Jackpot Slots

Few rewards compare to the largest jackpot slot pools. Mega Moolah and similar networks start the fun off with a €1 million jackpot. This jackpot gets a few pennies from each spin, which can make it reach staggering heights. Note that the largest progressive jackpot win to date amounted to €21 million.

Jackpot Slots

The main difference between jackpot and progressive jackpot slots is that the former does not increase with every spin. Their size is fixed and amounts to a player bet multiplier. You will most often find the maximum payout to be around 1000 times your wager.

Live Slots

There are a few differences between live and regular slots. The most notable is that live slot games feature spins that take place in real-time and are then beamed to your device. This adds a bit of atmosphere and additional fun to your gaming experience. When you combine this with a range of interesting hosts and interactions, you get a winning combination.

FAQ

While this is a very subjective question, and it is hard to say if slots outclass roulette or blackjack in every regard, we can say that the majority of players find them to be more entertaining and accessible from a financial aspect.

This tends to be closely related to the size of their bet, but it tends to be in the ballpark of 100s or even 1000s times their bet.

The acronym RTP stands for return to player, which is a percentage of funds that a slot will return to players given a certain time period. Let us take a slot with 97% RTP as an example. This slot will, in time, return €97 for every €100 it gobbles.

There is an ocean of options out there, which makes answering this question next to impossible. We recommend choosing those that seem the most fun but do not forget that you are pursuing entertainment and not monetary reward.
