👨‍💻 Online Slot Guide

Online slots are the most popular games you’ll find at Irish casinos online. They’re also the games that newbies will try out first once they join a casino. Playing an online slot game is easy and requires no special skills or strategies. This brief guide will show you how to play online slots and some key concepts you need to know.

How to Play Online Slot Games

So, you’ve picked an online casino to play at, but how do you play slots online? Well, slots are the easiest casino games to play and they don’t require any skills or strategies. Here’s a step-by-step guide that shows you how to play online slot games.

  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. Place a bet, click the 'Spin' button to start the game, and wait for the result to see if you hit a winning combination or not.


In this section, we’ll cover some key terms you’ll come across when playing slot machine games online for free or with real money.

  • Reels – Every online slot is made up of several 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 several 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 online 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’s a main game and one or more bonus rounds. 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 reaches 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

One of the reasons online slots are widely appealing to Irish players is that there are plenty of variations available. These games come with different themes, types, and mechanics. From classic slots with timeless charm to innovative video slots and jackpots, let’s look at the main variations of slots.

Classic Slots

These are the simplest and easiest slots you can play online, typically featuring three reels, one payline, and traditional symbols like fruits, bars, 7s, and bells. Also referred to as three-reel slots, classic slot games often have a retro theme and carry a weight of nostalgia with them. Bar Bar Black Sheep, Mega Joker, and Jackpot Jester 50,000 are some popular games in this category.

Video Slots

Video slots are the modern version of classic slot games, often consisting of five reels or more. These games come with the widest variety of themes, contain one or more bonus rounds, have adjustable paylines, better 3D animated graphics, special symbols, in-game features, and a bigger jackpot prize. Gonzo’s Quest, Starburst, and Jurassic Park are some popular examples of video slots.

Jackpot Slots

Jackpot slots are online games slot enthusiasts love the most. These games feature progressive jackpots that grow with each bet, creating an electrifying atmosphere of anticipation. Progressive jackpots are network-linked, meaning players in different locations can access the games which is why they can reach huge sizes. The biggest payout ever made online is €13 million which came from Microgaming’s Mega Moolah. Other progressive jackpot slots with the biggest payouts include Hall of Gods, Mega Fortune, Jackpot Giant, and Gladiator.

🎯 Tips for Playing Online Slots

When playing online slots, keep in mind that they’re all games of chance, so there’s no foolproof way to guarantee a winning result. However, there are a few tips you can use to enhance your winning odds and minimise the risks of losing money. Let’s go over some of these tips.

Check the RTP%

If you’re looking to play slots that pay real money, then you should check the RTP (Return to Player) percentage first. RTP represents the portion of wagered money a slot returns to players over time. Theoretically, if a slot game has an RTP of 95% and you wager €100, you’ll get €95 in the long run. Because the RTP is calculated over millions of spins, you can’t expect to see that return in a few game sessions. Always opt for games with higher RTP rates of at least 97%, as they offer better long-term payouts.

Get Familiar with the Rules of the Game

Before diving into the excitement, be sure to read the paytable. It contains all the rules of the game, how winning combinations are formed, the number of paylines the game has, and any unique feature or bonus rounds the game has. Mastering the rules of the game will enhance your gameplay and help you make strategic decisions.

Check the Bonuses

Casino bonuses can come in various forms, from free spins and cash credit to multipliers, and are a great way to play casino games without risking your money. The most common type of bonus you’ll encounter is the welcome bonus which you should do well to claim. It’s a good idea to check if the casino offers other bonuses you can grab. You should also prioritise slots that offer enticing bonus features like free spins and bonus rounds, so you have more chances of winning.

Read the T&Cs

If you happen to claim a welcome bonus or any other bonus when playing an online slot game, then it pays to read the terms and conditions (T&Cs). They tell you exactly how to use the bonus and how you can withdraw your winnings, including meeting the wagering requirements should you be lucky.

🎁 Online Slots Bonuses

When you play at the best online casinos, you’re sure to grab a variety of bonuses you can use to play online slot games. These bonuses vary from one casino to another in terms of size, free spins, and terms and conditions. Let’s look at four of the most popular slot bonuses you can claim at Irish online casinos.

  • Welcome Bonuses: The welcome bonus is the most common bonus you’ll come across at any online casino. These exclusive offers, often matching your initial deposit up to a certain amount, are usually available for all new players. You might receive a match deposit, free spins, or a combination of both as part of a casino’s welcome bonus.
  • No Deposit Bonuses: No deposit bonuses are rare to come across. They offer you an amount of bonus cash or free spins without requiring you to make a deposit. If you do receive a free spins no deposit bonus from a casino, be sure to read the T&Cs as such offers typically come with very high wagering requirements.
  • Free Spins Bonuses: You can receive free spins as part of a casino’s welcome offer or as a standalone deposit bonus. This type of bonus gives you several spins on specific slot games, offering the chance to win real money without wagering your funds.
  • Reload Bonuses: If you play often at an online casino, you can always receive reload bonuses from time to time. Reload bonuses typically invite you to make another deposit after your initial deposit. For example, if you receive a 100% reload bonus of up to €100 and you deposit €10, the casino will double your deposit, giving you an extra €10 to play with.
  • VIP Bonuses: Most online casinos offer special bonuses for their VIP players (high rollers). Reserved for VIP players, these bonuses can come in the form of cashback offers, random cash prizes, free spins, and more.

🔍 Top Online Slot Games Providers

There are more than 120 casino software developers powering the slots and other games you play at online casinos. Just like slots, some providers have become more popular than others, and most players tend to look out for these providers when choosing an online casino to join.

Here are some of the biggest software developers creating the best slot games you can play online.

  • Microgaming: Many would agree that Microgaming is the biggest and most well-known online slot game provider. Partnering with multiple independent game studios and producing their own titles too, Microgaming has the biggest game portfolio in the industry, and they also own the biggest progressive jackpot network in the world. They’re famous for some of the most iconic jackpot slots but their slot games are also very popular. Microgaming has the biggest number of casinos that offer their games, with hundreds of Microgaming casinos that offer no games from any other game providers.
  • NetEnt: NetEnt is another well-known game developer in the industry and is known for some of the most fun and unique online slots ever created. The Swedish game creator has been in the industry for more than 25 years now and they boast a game portfolio of more than 200 successful casino games. If you’ve never heard of NetEnt before, you’re likely to have heard of or even played some of their iconic slots, like Starburst and Gonzo’s Quest, two slots which remain widely popular many years later.
  • Play’n GO: Founded in 2005, Play’n GO is another Swedish online casino game developer that has become one of the leading names in the online casino industry. Other than a notable portfolio of online slots and other types of casino games, Play’n GO has made a name for itself with unique themes and impeccable slot designs. Play’n GO slots have some of the best graphics, sound effects, and visuals that never fail to impress players.
  • Playtech: Playtech was one of the first game providers in the casino industry and since their establishment in 1999, their games have remained a firm favourite among players. Like Microgaming, there are many online casinos which are solely powered by Playtech because they offer such a massive game portfolio. When it comes to the games, however, many Playtech games have a distinctive traditional art style and features that are unique to Playtech. Playtech’s Jackpot King series is also one of the biggest jackpot series, offering big progressive jackpots on many games.

📲 Play Online Slots on Mobile

Mobile gaming is quickly replacing desktop gaming as most players prefer to play from a mobile device. So, it’s easy to come across online casinos that have dedicated mobile apps for Android and iOS devices. You’ll also encounter casinos that don’t have a mobile app, as most online casino sites today are built with HTML5, removing the need to download any apps.
