How Slots Work
How do online slots work?
Unlike other casino games, such as blackjack and poker, playing slots online involves little skill. Luck alone determines whether or not you’ll hit a winning symbol combination when the reels stop spinning. Whichever symbols appear on the reals are determined by a random number generator (RNG), ensuring that the outcome of every spin is random and, as a result, fair.
This RNG technology determines which symbol will show on each reel at the end of the spin. The outcome of every spin is separate from the previous and next spin, which means you’re never ‘due’ a win. Likewise, if a slot has just paid out the jackpot prize, there’s no saying it won’t pay out again on the next spin.
Certain online slots have an ‘autospin’ feature, which allows you to set your wager for a specified number of spins until you’ve spent the assigned credit.
How to Play
How to play online slots
Slots are about as simple as it gets when it comes to online casino games- just set your bet, hit the spin button and wait to see if you get lucky. Even if you’re playing one of the latest video slots with multiple paylines and bonus features, the basic premise is the same. Sure, you might need to set your coin size and select the number of paylines you want to bet on, but that’s pretty straight forward too.
The more paylines you bet on, the more ground you cover. Just remember that your bet will multiply by the number of paylines you bet on, increasing your overall wager for that spin.
If you do land a combination of winning symbols, you’ll know about it. Music will play and images will appear on the screen to let you know that you’ve struck lucky. You’ll then have the option to use your winnings to play again or to keep them in your casino wallet.
Online slots might be simple, but there’s still plenty of variety when it comes to the games on offer. Whether you’re a fan of traditional fruit-machine style slot games, or prefer all-singing, all-dancing progressive jackpot slot games, the best online slot sites have something for everyone.
These slots hearken back to the days of fruit machines, though the symbols aren’t necessarily fruit, bells and lucky 7s. Most classic slot games have three or five reels, making it pretty easy to select your paylines, which are almost always in one direction. This simplicity makes them a popular choice among slots newbies.
Video slots tend to have more going on that classic slot games. Expect crazy themes, tailor-made soundtracks and graphics that could give some video games a run for their money. These games offer players multiple ways to win, with some titles offering over 1,000 paylines in every direction you could imagine. Video slots also tend to have more bonus rounds and in-game free spins than classic slots. Video slots are perfect for players looking to combine their love of online casino with their favourite films, tv shows and music genres, with software developers such as NetEnt and Playtech partnering with big production companies to create branded video slots.
You don’t need to be a high roller to play online slot games, thanks to penny slots. You can bet as little as 1 cent per spin on these titles, which is great if you want to play real money slot games but have a limited budget. But that’s not to say that penny slots are a budget option, you’ll still get high-quality graphics, top-notch soundtracks and the chance to win big.
Progressive jackpot slots
This is where real slots enthusiasts get excited. Whereas most slot games have a fixed prize for winners, the prizes for progressive jackpot slot games just keep growing! However, even progressive games come in different shapes and sizes. Whereas some jackpots are specific to the online casino at which you’re playing, others are pooled between different casinos sites. Whatever the nature of the progressive jackpot, the size of the prize pool increases as players wager. These jackpots have been known to hit the hundreds of thousands, with titles such as Mega Moolah and Mega Fortune making players millionaires!
You may need to bet the maximum coin size to be in with a chance of hitting the top jackpot prize.
Keep your favourite slots in your pocket
With so many players choosing their mobile for online gambling, slots developers create games with mobile players at the top of the priority list. This means there’s plenty of choice when it comes to mobile slot games. It goes without saying that virtually every online slots game in Ireland is available on mobile, but some of the best new slot games have been created especially for play on a smaller touch screen. Not only does this mean you can benefit from improved usability, but the graphics are also designed for mobile, which makes for an improved aesthetic, too.
Every slot site on our list has a mobile-friendly website, but the best have developed mobile casino apps for Android and iOS, which makes playing mobile slot games a breeze. You can get from your home screen to your favourite title in just a couple of clicks. Pay by mobile slot sites make it even easier, as you’ll have everything you need at your fingertips.
We’ve picked out the top slot sites for playing on your mobile.
Claim your bonus for online slots
The best online slot sites in Ireland reward players for choosing their site. A welcome bonus is the most common offer, but there are also other slots bonuses up for grabs through other promotions, such as happy hours and VIP rewards. You can get your hands on these bonuses at the top slot sites:
Free spins are the ultimate bonus for online slots. This bonus is as simple as it sounds: you can play real money slots using these tokens- no need to dip into your own wallet. Some online casinos offer a set number of spins when you make a qualifying deposit, whereas others offer free spins in relation to how much you deposit.
No deposit free spins
You don’t even need to make a deposit to claim a free spins no deposit bonus. Simply sign up, verify your account and opt-in. Once the free spins are credited to your account, you’ll be in with a chance of winning real money on slots, without spending a penny of your own.
Matched deposit bonuses are one of the most common casino offers. You’ll receive a percentage of your first deposit as free casino credit. Percentage matched will vary between online casinos, ranging from 25% to as much as 200%, though there’s almost always a limit to how much credit you can actually claim. These bonuses are ideal if you’re interested in other casino games, besides slots. Of course, you can play slots with this credit, but you can also use it on the likes of online roulette and blackjack games.
Some online casinos spread the matched deposit bonus across your first two or three payments rather than in one lump-sum.
No deposit casino credit
These bonuses work in a similar way to matched deposit deals, but you won’t need to dip your hand into your own pocket first. Much like no deposit free spins, you have a chance to win real cash even though you’re playing for free. No deposit bonuses are usually more modest than matched deposit deals— usually €5 free no deposit at most— but you can play a whole host of casino games, including online slots, with your rewards.
How to claim your bonus
Exactly how you claim the bonus will vary between slot sites. While some simply ask players to opt-in during the signup process, others need a bonus promo code. Be sure to check the bonus terms and conditions before you sign up to make sure you don’t miss out on a deal.
Bonus terms and conditions
There will be terms and conditions attached to whichever online slots bonus you choose and you’ll need to factor these in when comparing bonuses. Wagering conditions apply to pretty much every offer bar no wagering bonuses, and you can’t withdraw any bonus winnings until you complete these.
On top of wagering requirements, there are also other terms to consider. Some slots bonuses may only be used for selected titles, such as the newest games. Sites may also restrict how much you can win with your bonus, how long you have to complete any wagering requirements and how much you can withdraw at once.
Online slots are the most popular online casino games in Ireland, attracting more players than roulette, blackjack or any other game type.
Free Slot Games
Play slots online without spending a penny
You don’t need to spend a cent to play online slots. Pretty much every slot game, with the exception of progressive jackpot titles, are available in free play mode. Free online slot games are ideal if you simply want to play slots for fun or try out a new slot game before you put real money on the line.
Of course, you can’t win real money when you play free slots, but you do get to sample all the same bonus features as real money games. Whether your title features expanding reels, walking wild symbols and scatter symbols, you get to see what all the fuss is about without dipping into your own wallet.
A fresh, new look on this casino classic
The great thing about online slot games is that there are always new titles popping up. There’s plenty to keep online slots players entertained as multiple brand new slot games are released each month. With each new release, online slots developers wow players, be that with bigger brand partnerships, higher definition graphics or bigger progressive jackpots.

High RTP Slots
Maximise your chances of winning with high payout slots
It’s important to understand the return to player (RTP) percentage of a slot game before you start playing, as this gives you an idea of how much you could theoretically win. These percentages are calculated over an infinite number of spins, which means you could win more or less than this percentage of wagers during your period of play.
When it comes to RTP, the closer to 100% the better. Most online slot games have an RTP of around 90% and those over 96% RTP are generally considered high payout slots. However, some of the highest paying slots offer even higher payout percentages.
