Best Slots Bonus Welcome Offers in Ireland

In this section, we share our two favourite slot welcome bonuses available in Ireland, explain a few of their key features, and our overall view of them.

Number 1: Dream Vegas’ Welcome Bonus 

Features: up to €7,000 and 120 free spins on your first three deposits.

Wagering requirements: x35 the total value of your bonus money, deposit amount, and winnings from free spins.

Need to know: slots, scratchcards and Keno count 100% to wagering, while all other games, such as table games and progressive jackpot slots are excluded.

Our view: it’s great to get a casino bonus spread over several first deposits and this one isn’t spread thinly at all. The initial first deposit bonus is a 200% deposit match bonus up to €2,500, but the next two deposit bonuses are great too.

Best Slots Bonus Free Spins in Ireland

Here, we share one of our favourite slot free spins offers for Irish players and go briefly into their details, to help you decide if they're worth claiming. 

Number 1: Casino Mega’s 330 Free Spins

Features: up to €1,500 plus 330 free spins.

Wagering requirements: wager your deposit amount once and your bonus 50 times.

Need to know: you can get 100% up to €1,000 and 300 free spins on your first deposit, then 50% up to €500 and 30 free spins on your second deposit. Plus, live casino games only count 20% to your wagering fulfilment and wagering must be done in seven days. Also, to get the full 330 free spins, you need to deposit at least €300 — you’ll get 20 free spins on your first deposit and 30 on your second if you just deposit the minimum €20 each time.

Our view: 330 free spins is nice if you can get it. Plus, the total €1,500 in deposit bonuses will allow you to bet more on slots or spend it on something else. 

Best Slots No Deposit Bonuses in Ireland

No Deposit bonuses are always popular so we’ve selected a couple to get you moving on slots. This fine pair provide 22 no deposit free spins, and 200 free spins with the help of a friend.

Number 1: Slot Planet's 22 No Deposit Free Spins on Dead or Alive 

Features: get 22 free spins on the Dead or Alive cowboy slot, just for signing up, and get a 100% bonus up to €222 plus 22 free spins on Starburst for your first deposit of at least €10.

Wagering requirements: x35 your bonus funds, including any winnings from the no deposit free spins.

Need to know: you can't claim this offer using Skrill or Neteller. Any winnings with the no deposit spins are capped at €100.

Our view: you get 22 free spins just for joining, which is always great! It’s a shame potential winnings are limited though, and there's wagering to consider, but we think it’s worth a try. 

Number 2: Cosmic Slot's 200 Free Spins for You and a Friend

Features: a 200 free spins bonus when your friend signs up for an account, makes a qualifying deposit, and contacts customer support to say you sent them.

Wagering requirements: x40 on winnings.

Need to know: your friend must register through the site's regular URL, not a third-party. You'll receive the 200 free spins as soon as the invitation is confirmed and you only have 24 hours from the time your friend makes their deposit to use the bonus.

Our view: okay, so there aren't a lot of no deposit bonuses available right now, so we've suggested this alternative refer a friend bonus, which doesn't require you to make a deposit, but your friend will need to. There is a meaty wagering requirement on any winnings, but you can at least play slots for free.

Popular Deposit Bonus Slots

The best slots in Ireland often feature in slot bonus offers but what makes them special, and is it worth claiming free rounds on them? We answer these questions and more in the following section.

Rich Wilde and the Book of Dead

Book of Dead is a slot by Play’n GO, a software provider that tends to create aesthetically-pleasing games with imaginative plots, making for a deeper experience besides just betting.

This game features in many slot bonuses but why? For one, its simplicity is good for people betting on slots for the first time. On the other hand, it seems sites are fairly safe offering free spins on this slot, because it has high volatility. Also, the RTP is 96.21%, which is just above the average slot RTP of 96%, so, although fun to play, you’ll be lucky if your free spins yield a mega win.

What’s more, Book of Dead has five reels and ten paylines, which is more paylines than classic slots but less than new Megaways games.

• Get 200 free spins on Book of Dead with Kwiff’s welcome bonus
• Get 100 free spins on the slot at Casino Days.
• Get 200 bonus spins on Book of Dead on your first deposit at LeoVegas

Starburst

It’s exciting to get free spins on Starburst, possibly the most famous slot game ever made. Like Book of Dead, it has a modest RTP of 96.01%, but its low volatility means there’s more chance of wins on this slot but they could be smaller.

The max single win on NetEnt’s Starburst is x250 your bet and there are ten paylines to win on. You can also trigger free spins and sticky wilds.

• Playhooley’s current deposit bonus for slots lets you use free spins on Starburst
• The Griffon Casino welcome bonus offers you bonus spins on Starburst, Book of Dead, and Fire Joker!

Types of Slot Bonus

When it comes to bonuses, slots are where it’s at – most welcome bonuses relate to slots in some way and free casino spins offers are common. What’s more, if you’re lucky enough to grab a no deposit bonus, it will likely give free spins on casino slots or bonus money that you’ll need to wager on slot games. In this section, we explain the best Irish slots bonuses in more detail.

Welcome Bonuses

When you sign up for an account at an online casino in Ireland, you can almost always grab a promotional offer. It’s a nice way to introduce you to the site, plus of course, it’s a marketing tool that gives you another reason to sign up and deposit cash.

If you’re going to choose a site based on which has the best slot bonus, then you could have your work cut out – there are so many different welcome offers, each with its pros and cons. If sorting the great from the good seems like too much work, the Casinos.com bonus experts list the best slot bonuses on this page, saving you the trouble. 

Free Spins Online Slots Bonuses

When you think of online slots bonuses, free spins are probably the first thing that comes to mind. They’re a common bonus at online casinos, because slots are popular and they’re generally good for the casino’s pocket. Sometimes you can get no deposit bonuses on slots but even then, you will likely have to fulfil wagering requirements before you can withdraw real cash.

Slot Deposit Bonuses

A deposit bonus is a reward and incentive sites give you for making a deposit and the value can come in different sizes. A deposit bonus tends to be a percentage of the value of your deposit given back to you in bonus money, which you then need to bet a certain number of times, before you can withdraw the bonus amount, and any winnings with it, as cash.

Match Deposit Bonuses

While deposit bonuses are more general, a deposit match bonus is bonus money based on the amount you deposited, hence ‘match deposit’. For example, you might get a 100% match on whatever you deposit, up to a maximum of €500. This is usually part of a welcome offer. 

Slot Reload/Cashback Bonuses

A reload bonus, aka a cashback bonus, is an offer typically given to a casino player who’s already created an account and made at least one deposit. You can see a reload bonus as an incentive that encourages bettors to bet more and also a ‘parachute payment’ that cushions the blow if you lose the money you deposit during a week or set period chosen by the site.

For example, the aptly-named Reload Casino gives bettors 10% cashback on all their losses every week they deposit at least €20, up to the value of every deposit in the previous seven days.

No Wagering Slot Bonuses

Some sites offer no wagering slot bonuses. This is when you can withdraw bonus money without first needing to play it through several times. Here are some examples of slot bonuses with no wagering requirements:

• Kwiff Casino’s 200 free spins on Book of Dead with no wagering on winnings.
• No Bonus Casino’s 10% daily cashback

No Deposit Bonuses for Slots

The golden goose of slot bonuses, a no deposit bonus gives you a reward without needing to deposit any money. These bonuses tend to be used by sites to attract you to create an account. The casino site hopes that you’ll be convinced to keep betting and make your first real money deposit. 888casino is one of the sites with a no deposit bonus.

Mobile Slot Bonuses

As the worlds of desktop and mobile casinos gradually merge, the bonuses you can claim on any device also become the same nine times out of ten. So you can usually assume if you find a casino bonus in Ireland when you’re surfing for promotions, each one will be available on mobile, tablet, and desktop. You can even play real money casino apps now, so getting your bonuses is as convenient as ever.

Slot Bonuses Terms and Conditions

Each online bonus on slots comes with a list of terms and conditions we advise you to pay attention to. Here are some features of slot bonus terms to look out for. 

Slot Bonus Wagering Requirements

You can win real money on slots but almost all slot bonuses come with rollover requirements. This means you must bet your bonus amount a certain number of times, before you’re eligible to withdraw any cash winnings. 

Wagering or rollover requirements protect casinos from bonus abuse. Without them, players could take bonus money and run, without ever depositing real money. Despite this, as you see earlier on this page, some sites do offer no-wagering bonuses.

Games Not Included in Slot Bonuses

Live casino games, progressive jackpot slots, sport bets, and poker are often excluded from slot bonuses. You’d expect the best slots games and mobile casino slots to be included, and they usually are — sometimes all slot games, except progressive jackpots, are included and can be used with free spins offers and to fulfil wagering requirements. But other times, only one or a limited list of slots can be played to fulfil wagering requirements. This gives slot sites more control over how much they risk losing through these bonuses. 

Payment Methods Not Accepted for Slot Bonuses

Many bonuses can't be claimed if you use an e-wallet like Skrill, Neteller or PayPal even if it's one of the online casinos that accept PayPal, etc. You can assume debit cards like Visa and Mastercard are a safe bet 99% of the time though. 

Value of Free Spins

Don’t be surprised to find that free spins have a limited value. Some are worth €0.10 per spin, so your winnings are somewhat limited.

Maximum Slot Bonus Winnings

Many offers come with a winnings cap. For instance, you might be able to win a maximum of €500 in real money after you’ve fulfilled all the wagering requirements. 

Other Slot Bonus Terms You Should Know

The following conditions are true 99% of the time, but there are exceptions:

• All slot deposit bonuses come with a minimum deposit amount, which is usually €10 or €20.
• You can only claim one welcome bonus per account and per household.
• You must be located in the country where the bonus is eligible, e.g. some Irish slot bonuses aren’t available in Northern Ireland. If you claim a bonus from an ineligible country, the casino site can refuse to give you your bonus.
• Some bonuses expire within 48 hours if you don’t claim them, and once claimed, some bonuses expire after seven days, for example, if you haven’t completed the wagering requirements.
• You must be over 18 years old to claim a bonus.
• Online slot games usually count 100% to wagering requirements, while table games might count 20%, and live casino games might count just 10% or even zero.
