Top Irish Casino Sites with Slot Bonuses

Most online casinos are going to come with some sort of welcome offer. However, if it’s just online slots that you’re interested in, then you will be better off finding something that is dedicated to this game type.

From the table below you can pick out the best slot casino sites in Ireland right now. Not only do we tell you places that you need to try, but we include our overall rating for that casino along with information about their licensing, so you know they are legit.

How we Review the Best Slots Bonus Casino Sites

If you’ve read any of our reviews at Slot Source you will know that we do things a little differently around here. If you are new, then you’re going to be pleasantly surprised.

One of the reasons that we set the site up is to change the way that casinos were reviewed. We didn’t want to just throw up a generic review and instead, we wanted to go further and deeper than any other casino review site.

To do this we have created a dedicated team for each section of online casino. This team is set up to target slots bonuses specifically, but also to then look at the bigger picture and explain to you about the package that’s on offer from each of them.

Our team isn’t just a group of randoms either. They have been hand-picked to come together to offer the best impartial advice that we can put our name to.

These include professional casino players, game developers, casino media and keen players. This mix allows us to look at a number of perspectives which we think will tick more boxes with our readers, instead of just a single viewpoint.

The team also means that we can cover our reviews in much greater detail than a one-man-band. Sections are handed out to each researcher and from there they pull their findings. Once this has been completed then they start to get an overall feel for the casino and then bring together their review.

With each review, there is a basic guideline that the team follows. However, we must stress that it’s not set in stone for each casino. It’s important to be flexible here given that some sites will have certain features that need more work to be undertaken. New slot sites pop up all the time, so we’re always on the lookout for the latest competitor to hit the market.

The first port of call is the bonus and the amount of money on offer. The "higher the better" is a common misconception with these offers as it’s all tied into the wagering requirements.

Working through these requirements is a skill in itself and making sure that all info is taken from the T’s and C’s set out by the casino is portrayed back to our readers. These terms are more transparent now than they have ever been to be fair, but if you are new, then there will be plenty of things that you weren’t aware of that we then point out for you.

Wagering requirements cover a broad scope of information but as an overview include things like amount needed to clear the bonus, timeframe for that bonus, games that contribute, wagers that contribute and more.

Once the bonus is out of the way, we then move onto the casino itself and how many slot games are on offer. There will be hundreds to choose from, so we test as many as we can. It’s worth noting that lots of casinos use the same game providers meaning that there is often crossover between games. This saves us time as we know how they work, but the games are still noted for the sake of the review.

It’s important to consider all aspects of the casino as well. This includes everything from banking through to customer support. They may have the best range of games and best bonuses in the world, but if you can’t easily get money in and out, then it becomes pointless.

We will finish with a note that it’s important to keep checking back on this page for updates. We are testing bonuses and casinos daily, so what’s the best today, might not be the best tomorrow.

Choosing the Best Casino Bonuses for Slots Games

Online casinos offer a number of different types of bonus for slot games. Eligibility will depend on many different factors such as what type of bonus it is and the slot it is offered on, whether you have visited or played at that casino before or used other types of slot promotions they have offered in the past.

Online casino bonuses for slots are far bigger than those offered at traditional land-based casinos and are increasingly popular amongst slot game players. The most common of these is a deposit bonus, which is a standard bonus offered by the majority of online casinos and is only available to new players. Once players make a deposit over a specified value into that casino account, the deposit-based slots bonus will kick in and reward them accordingly. The reward could be free spins, or it could be a deposit match bonus - this where the casino adds the same amount of your deposit to your account for free. At the best online casinos, you will get a mixture of both these types of slots bonuses as part of your welcome offer!

As an alternative to a straight 100% match, they could offer even more than what was originally deposited. For example, if you deposit €100 and take advantage of a 200% welcome bonus, the casino will match your deposit x2, adding €200 to the original €100 which gives you a total of €300 to play with. Deposit bonuses are sometimes staggered to keep players coming back for more slots offers. Players may be offered a 100% match deposit bonus on their first deposit, and then another 50% (or more) on their second or third.

No deposit bonuses are less common but very attractive as they allow you to test games and the casino, for free. With these online slots bonuses, players will be given a free gift before they have even made a payment into their account. Online casinos that offer this type of slots promotion are looking to increase their player numbers and get you to try their products in the hope that you find a new home for playing slots online.

The casino that you choose needs to be based on the games that you want to play and the ability to clear the bonus. We will suggest bonuses and offers that you can take advantage of, but in reality, what works for one player, might not another.

This is why one of the processes that we have in place is to not come up with a “best” offer as such, but an overview of a group of offers that we think will suit a wide range of casino players.

A common mistake that we see from new players is that they often take the biggest bonus amount on offer. However, you will find that the bigger the bonus the harder you have to work to clear that bonus. This means that smaller bonuses will offer better value to a lot of players given that they have a chance of actually clearing the bonus and claiming the bonus money as cash.

Finding the Deals: Slots Bonus Offers

Our role is to bring you the best slots bonus offers that we can. We search and review hundreds of online casinos to do this and we don’t stop until we’ve reviewed them all.

The majority of our time is spent within the T’s and C’s of any bonus. It’s only once we’ve completely gone through these that we can assess if a bonus is worthy of promoting or not.

You need to bear in mind that the volume of offers that we look through allows us to be totally impartial. Yes, we want to make sure that you get the right slots bonuses for the games that you want to play, but we won’t push a site based on reputation just for the sake of it. The range of bonuses on offer means we simply don’t need to push bad offers.

It’s also important to make sure that you keep bonus expectations in line. Bonuses generally aren’t easy to clear, and you have to work hard to get your free cash.

That being said, they aren’t impossible either and the casino dangles the carrot to make sure you have to work a little for your money. Some make you work harder than others, which is where we come in to alert you which offer the best value.

Types of Slots Bonuses

Online casinos are ever-changing and the bonuses that come with them are one of the easiest things that they can change. Any two offers rarely are the same, but there are plenty that has a similar theme to them.

Below we have included a range of bonuses that you’re going to be able to access at several online casinos.

Welcome Bonuses for Slots

Welcome bonuses are for new players to “welcome” them to the casino. This is the most popular type of bonus that you can get and is the one that most of you will be claiming.

These offers are generally your bigger offers and can range from any of the below in terms of what’s on the table.

Free Spins Bonuses

Free spins are all based on slots and these are as much a taster to the slots section than anything else. You can get these offers on their own and you can get them working alongside another offer as part of a package deal.

The number of free spins that you get will vary. Sometimes the winning from these spins will be paid as cash and sometimes they will be rolled over into a bonus amount.

It’s worth noting that in Ireland they aren’t always called free spins and could be anything that includes bonus spins, extra spins, super spins etc. However, they all mean the same, it’s just the term “free” has been banished by new legislation introduced by Ireland Gambling Commission.

Deposit Bonus

The deposit bonus is another of the more popular ones. This is where the casino will match the amount that you deposit up to a certain amount.

Offers like this will range based on if you’re a new customer or if you are a returning one. The bigger offers are usually reserved for new customers, however, reload bonuses are not uncommon for existing players.

Online Slots No Deposit Bonus

These are as rare as hens’ teeth these days, but if you’re lucky you can still grab the odd no deposit bonus. As the name would suggest, this is a bonus that the casino will give you for simply registering an account, with no deposit needed to trigger a bonus.

It’s worth noting that the sums of money at stake here are often low. They are usually almost impossible to clear as well. However, they are great for getting a look at a new casino without having to financially invest.

Special Offers on Slots

A wide range of casinos now promotes several special offers on certain games. They are almost always linked with the launch of a new slot and in return, it gives players the chance to play these games for free but with real money.

The offers range, but they are including things like slots tournaments, extra prizes based on your wins, cash, gadgets, cars and many more.

Reload Slots Bonusses

These offers are for existing players once they have made their initial deposit and usually claimed the welcome offer that goes along with this. Casinos will offer a bonus on 2nd, 3rd, 4th and even up to a player’s 5th deposit at that casino.

Cashback Slot Bonuses

A cashback offer is where the casino will refund some of your based on how much you play and the amount that you deposited. Again, these are pretty rare these days but offer good value if you can get a hold of one.

How to Get a Slots Bonus Deal

  1. Choose a casino | Select from our list above and see which one offers the best bonus to suit your playing needs. Free spins bonuses will be most appealing to those on a smaller bankroll whilst deposit match bonuses give you the freedom to choose the game and price of spin you want to play at.
  2. Check the T&Cs | Make sure that you take the time to read the terms and conditions for any offer before you register an account. These documents are highly accessible and much easier to decipher than they used to be, making them an essential process before creating an account.
  3. Open an account | In order to take advantage of a bonus slots, players will first need to create an account with that online casino, Irish regulations require that you use accurate details here so don’t be worried if you have to provide ID etc – this is the law in Ireland and all fully licensed casinos must ask for this.
  4. Activate a slot bonus | Some bonuses, such as no deposit bonuses or free spins, can be activated and ready to use once you have confirmed your new account. Some require a promo code – if you are unsure contact the casino live chat and they should help.
  5. Make a deposit | Most of the biggest bonuses, such as deposit or matched deposit bonuses, require money to be paid into the casino account before the bonus can be used. Players must link their account to a payment method and transfer funds to the online casino. It’s worth noting that not all payment methods will be eligible to claim a bonus deal. This means that if you were to deposit with a method that is not eligible, you would not be able to trigger the bonus. You can easily see which payment methods are not accepted within the T’s and C’s. As a general rule, the likes Skrill, Neteller and PayPal are popular payment methods that are often excluded from claiming a welcome bonus.
  6. Start spinning! | Once you have your deposit bonus, start using it to play slots. If you win using the bonus spins or credit and have fulfilled the wagering requirements, you will be able to withdraw the funds, or use them to play more slot games.

Why You Should Read the Slot Bonus Terms and Conditions

  • Percentage amount that certain slots contribute towards the bonus wagering
  • Payment method restrictions that might make your deposit not eligible for the bonus.

What is a Slot Bonus Wagering Requirement?

All bonuses come with a wagering requirement. We’ve spoken about these numerous times already throughout this page, but we wanted to dive a little deeper about how they work.

The main concept behind a wagering requirement is to make sure that players don’t simply take the money and run before playing any games. This way the casino is happy to offer a player a reward for signing up, but they need to work for this reward.

Terms will be based around a multiple of the bonus and sometimes a cumulation of the bonus and the deposit amount. For example, a typical offer would be based at 30x your bonus, meaning a €100 bonus would require €3,000 worth of wagers to clear that bonus (30 x €100).

You’re going to need to note which games they allow you to clear bonuses on as well. Some may limit the range of slots you can access, and some may even disregard a whole range of games altogether (table games being a common example of this).

Other things that you need to keep an eye out for here include the payment methods accepted to trigger the bonus, the timeframe that you have to complete it in full and the max stake that will contribute towards clearing.

Is There a Limit on How Much You Can Deposit at a Slot Site?

Most casinos will have limits based on the amount you can deposit on their site. All of them will have a minimum amount, which is usually around €5 to €10. Even though some may state that you can only deposit up to a certain amount with a payment method, most will allow you to make as many deposits as you need, meaning there’s not usually a cap on the maximum amount.

The type of payment method that you use will be limited as well. Generally, you see that debit cards and bank transfers are the highest, with e-wallets and online payments being quite a bit lower in terms of upper limits here. A list of the most popular payment methods include:

Do All Slot Bonuses Require a Promo Code?

Very few bonuses come with promo codes these days. They are much more inclusive than they used to be with these so they only get distributed for one of the deposits, usually as gestures of goodwill from the casino.

We will add that those casinos that do require you to enter a promo code will need you to do this before making your first deposit or at the time of doing so. You won’t be able to go back and add one should you fail to do so from the off.

Do Slots Sites Have Loyalty Programs?

A lot of slots sites do have loyalty programs attached. Some of them are now highly lucrative as well, with many players choosing to target these over the likes of welcome offers and deposit matches.

A good loyalty program will allow you to earn points whilst you play pretty much any game at the casino. The more games that you play or the higher the amount of revenue that you stake, the more points that you will earn.

Rewards can be highly lucrative here. They will range from small bonuses to free cash, with VIP experiences, concierge services, special banking priorities and everything else in the middle.

Mobile Slot Bonuses

The success and the accessibility of the mobile casino mean that mobile-specific offers are no longer as common as they once were. If you do manage to find one, then they don’t hang around for long and you’re only able to access a limited bonus as a result.

That being said, it’s worth noting that pretty much all casinos allow players to clear their bonus on games played on mobile or via their app, both Android and iOS. Casinos are set up in a way that everything is integrated (mobile and online) so there is no difference if you play the same game online or on your mobile device.

The only issue that you might have is that not all games are available on mobile and online just yet. It’s rare, but there is a chance that your favourite online game is not yet on mobile, so you won’t be able to clear a bonus playing on this game.
