Online Slot Guide

The most popular casino games at any online casino in Ireland and the games that most newbie punters try out first are online slots. Online slots are the easiest casino games you can play because as games of chance, there are no skills or strategies required to play. Although online slots vary from one to another, the basic premise of any slot casino game is that you place a bet, spin the reels, and wait for the result to see if you get a winning combination or not.

How to Play Online Slot Games

Below, we’ll walk you through how to play online slot games, step by step.

  1. Register at an online casino by clicking the ‘Sign Up’ or ‘Join’ button and completing the registration form.
  2. Choose if you would like to claim the Welcome Bonus or not.
  3. Select the game you would like to play with real money.
  4. Open the paytable to familiarise yourself with the rules of the game, what each symbol pays, and how winning combinations are formed.
  5. Click the 'Spin' button to start the game.


In this section, we’ll go over a few key terms that you’re likely to come across when you play online slots for free or for real money.

  • Reels – Every online slot is made up of a number of reels and rows. The reels are the columns while the rows indicate the number of symbols on each reel.
  • Symbols – The symbols are the icons that appear on the reels of online slot machines. Every slot machine has a number of different symbols which are worth different payouts and the images usually match the theme of the game as well.
  • Payline – To get a winning result in a slot, symbols must form the right combination on a specific line that’s known as a payline. If symbols line up on a payline in the correct order (according to the paytable), a winning combination is formed and a payout is awarded.
  • Bet Amount – This is the amount you decide to stake per round, i.e, every time you spin the reels. You can change your bet amount after every spin, except during Free Spins or a bonus round.
  • Free Spins – Free Spins are spins which you don’t pay for, and they can be triggered when playing slot games or awarded by the casino. If you trigger a winning combination when using a Free Spin, you get a real payout without having staked any real money.
  • Bonus Rounds – In almost all casino slots, there is a main game and one or more bonus round. Bonus rounds can be Free Spins, a round where you pick random symbols to reveal cash prizes, or anything else that doesn’t happen in the main game and typically awards bigger prizes.
  • Auto Play – A feature that can be found in all the online slots Ireland offers, this allows you to play a number of spins automatically, without clicking the spin button after each round.
  • Progressive Jackpot – A jackpot prize that increases progressively with a percentage of every bet placed on the game. A progressive jackpot prize keeps growing until it’s won or until it reached the capped maximum (if it has one).
  • Max Bet – The maximum bet amount allowed per spin. The maximum bet varies for every game and depends on the casino too.

Online Slots Variations

What makes online slots so widely appealing to many Irish players is that there’s a great deal of variety available. Casino slots come in all types, themes, and mechanics, as you can see in the following sections.

Classic Slots

Classic slots are the simplest and easiest online slots you can play, typically consisting of just three reels and one payline. These slots are designed to mimic the classic one-armed bandits from the days before online casinos existed and often have a very retro theme and a nostalgic look. Also referred to as three-reel slots, classic symbols like fruits, golden bells, and four-leaf clovers give players a nostalgic vibe.

Video Slots

Video slots are essentially the modern version of online slots, generally consisting of a game grid made up of five reels and three rows. Additionally, video slot games have the widest variety of themes, with some popular ones being Asian-themed slots, ancient Egypt slots, and of course, online slots with a luck of the Irish theme. Video slots also have more action-packed gameplay because they generally offer bonus rounds like Free Spins, respins, and special symbols too.

Multi-Payline Slots

Multi-payline slots simply refer to video slots which have multiple paylines, unlike classic slots which have a single payline. This can be anywhere from 10 paylines up to 100 or even more, depending on the game.

Slots with Bonus Games

Online slots with bonus games are slots where you can trigger a bonus round either randomly or by getting the right symbol combination on the reels. Bonus rounds can include Free Spins, Prize Pick bonuses, prize wheels, or mini-games.

3D Slots

3D slots are video slots with enhanced graphics that make the symbols and images in the game look 3D and as realistic as possible. Nowadays, most online slots are 3D slots because they are the most visually engaging online slots to play.

Progressive Jackpot Slots

Progressive jackpot slots are like regular casino online slots but they offer the chance to win a progressive jackpot. This is a jackpot that increases in increments by taking a small percentage from every bet played on the game. Progressive jackpots are connected through a network which means that even if players are playing at different online casinos, a percentage of all their bets will go into the pot.

Megaways Slots

Megaways slots revolutionised the online slots world when the very first Megaways slot was released back in 2015. Invented by Big Time Gaming, Megaways is a type of game mechanic that changes the formation of the reels on every spin, increasing or decreasing the number of rows on each one. With this mechanic, Megaways slots offer up to 117,649 ways to win on each spin! Instead of traditional paylines, you get all these possibly winning ways to hit a win, which is why these games are incredibly popular in Ireland.

Tips for Playing Online Slots

Now that you’ve learnt a little bit more about important slot casino terms and the different types of slots you can try out, let’s go over a few tips that would be good to keep in mind when you play slot games online! Do keep in mind, however, that online slots Ireland are all games of chance, so there is no way to guarantee a winning result. Nevertheless, there are a few tips that will help you play with the best possible odds of winning and minimise the risks of losing money too.

Check the RTP%

If you’re looking for the best online slots in Ireland that pay real money, the first thing you’ll want to do is check the game’s RTP rate. The RTP, or Return to Player, will give you an indication of how much the slot pays back on average. Theoretically, if a casino game has an RTP rate of 95% and you bet €100 on it, you should get back €95 in the long run. The RTP percentage is calculated over a million or more spins, so you can never expect to see that return in one or even multiple game sessions.

So, you might be wondering, what’s the point of checking the RTP rate if it’s only a theoretical percentage? The reason is that the RTP rate is still a great indicator of the winning odds of a game and the higher the RTP rate, the higher your chances of winning real money will be. As a rule of thumb, keep in mind that the average RTP rate is around 96%, which means that anything above this percentage is considered a very good RTP rate while anything less is considered quite low.

Get Familiar with the Rules of the Game

Before you hit the spin button, don’t skip reading the paytable, as this is an important step to playing online slots that pay real money. The paytable can be accessed easily from the game panel below the reels and this is where you can find all the rules of the game, the number of paylines or ways to win, how winning combinations are formed, and any special features or bonus round that the game offers.

Check the Available Casino Bonuses

Online casinos always offer some kind of casino bonus that you can use to play with bonus cash instead of your own funds. The easiest bonus you can find is, of course, the Welcome Bonus, which every new player can claim but there are also other bonuses that might be offered at the casino. In short, it’s worth checking if your online casino has any ongoing promotions or bonuses that you’re eligible for before you start playing with your own money.

Read the Casino’s Bonus Terms and Conditions

One of the most important tips that are often overlooked is to read the bonus terms and conditions very carefully. The terms and conditions will explain exactly what you need to do to claim the bonus and how you can withdraw any winnings, such as withdrawal requirements, for example. You’ll also find important information about which payment methods are eligible for the bonus, as there are usually a few payment methods that will exclude you from the bonus. If you don’t read the terms and conditions carefully, you can easily make a deposit only to realise you’re not eligible for the bonus. So, to avoid any potential disappointment, it’s crucial to read the T&Cs carefully.

Top Real Money Slots for Irish Players

Although there are thousands of online slots Ireland players can play, there are always a few titles that seem to be popular with nearly every player. These slots are instant hits that never seem to get old, whether it’s because they have a high RTP rate, a big jackpot, or simply a really fun theme with engaging gameplay. We’ve rounded up five of the best slots to play online for real money.

Free Online Slot Games VS Real Money Slots

When you play online slots, you can usually decide how you want to play. You can either play online slots that pay real money by staking real money as well or you can play for free. Most online casinos in Ireland offer players the chance to try free slots demo games, which are the free version or a regular online slot.

Free slots are just like real money slots except that you don’t spin the reels with real money and no real payouts are awarded either, as it’s all simulated.

The table below lists some of the most important differences between free slots and real money online slots that you should be aware of.

Online Slots Bonuses

Irish punters visiting any online casino will find a range of slot casino bonuses that they can get their hands on to play with a little something extra or try out the best online slots with bonus money. These bonuses always vary from one casino to another, especially when it comes to terms and conditions. Below, we’ll take a look at four of the most common casino slots bonuses that you can find at many Irish online casinos.

  • Welcome Bonuses: The welcome bonus is a standard bonus at any online casino in Ireland and the first bonus you can claim when you join a new online casino. This bonus is intended to encourage players to choose an online casino and make their first deposit there and it’s typically one of the best bonuses that can be found at the casino. After all, the easiest way for an online casino to make a good impression on prospective players is through the welcome bonus.
  • No Deposit Bonuses: A highly coveted type of casino bonus that’s rather rare to find is the no deposit bonus, a bonus where you get an amount of bonus cash or a number of free spins without having to deposit a single cent. Registration is required, but that’s all that’s needed to claim the bonus. Once again, it’s particularly important to read the terms and conditions attached to an online slots no deposit bonus because these bonuses typically have very high wagering requirements. Since you don’t even need to make a deposit, the casino often requires you to wager large amounts before you can withdraw any winnings made using the bonus.
  • Free Spins Bonuses: Free spin bonuses can be part of a welcome package that consists of a match bonus along with a number of free spins, or a welcome bonus on its own. Alternatively, it can also be a casino bonus offered to regular players and it’s a very popular type of bonus that can be found at any Irish online casino. A free spin bonus awards a number of free spins in exchange for a deposit and as always, terms and conditions do apply.
  • Reload Bonuses: A reload bonus is a type of deposit bonus that casinos offer from time to time to encourage their existing players to make a deposit. It’s an incentive to tempt players to make another deposit for a little something extra. For example, a reload bonus can be a 100% bonus up to €100, which means that the casino will double your deposit. It can also be a 50% bonus, for example, which will match half of the deposit you made. This means that if you deposit €10, you get an extra €5 added to your balance.
  • VIP Bonuses: Most online casinos offer special bonuses and promotions for their VIP players which can be any kind of bonus, including free spins, cashbacks, random cash prizes, and more. These bonuses are exclusive to VIP players only.

Playtech’s Jackpot King series is also one of the biggest jackpot series, offering big progressive jackpots on many games.
