Best Slots Bonus Welcome Offers in Ireland

Below, we’ll highlight our favourite slot welcome bonuses available in Ireland. We'll break down their key features and share our thoughts on each one.

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% towards the wagering. 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 free spins offers for Irish players and give you a quick rundown to help you decide if it’s worth claiming.

CasinoMega’s 330 Free Spins

Features: Up to €1,500 plus 250 free spins.

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

Need to know: The bonus breaks down like so:

• 100% up to €1,500 + 50 free spins on Big Bass Splash on your first deposit
• 50 free spins for the next 4 days after

Live casino games only count for 20% of your wagering fulfilment, and wagering must be done in seven days. Also, you will receive the 250 free spins over 5 days (50 each day)

Our view: 250 free spins is nice deal 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.

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.

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, it’s a marketing tool that gives you another reason to sign up and deposit cash.

Choosing a site based on the best slot bonus can be a bit of a challenge. There are many different welcome offers, each with pros and cons. If sorting the great from the good sounds like too much work, our 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. They’re also good for the casino’s pocket. Sometimes, you can get no deposit bonuses on slots. But even then, you'll have to fulfil wagering rules before withdrawing real cash.

Slot Deposit Bonuses

A deposit bonus is a reward sites give you for making a deposit, and the value can come in different sizes. It's a percentage of the value of your deposit given back to you in bonus money, which needs wagering. Only then can you withdraw the bonus amount and any winnings 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 the term ‘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 Cashback Bonuses

A cashback bonus is an offer given to a casino player who’s already created an account and made at least one deposit. It's an incentive that encourages bettors to bet more. It's sometimes called a ‘parachute payment’. It cushions the blow if you lose the money you deposit during a week or set period chosen by the site.

For example, casinos like Reload offer players 10% cashback on weekly losses as long as they deposit at least €20. The cashback is calculated based on the total deposits made 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, 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. But sometimes, 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 or PayPal, even if it's one of the online casinos that accept PayPal. 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, 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. Once claimed, some bonuses expire after seven days 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% towards the wagering requirements. Table games might count 20%, and live casino games might count just 10% or even zero.

How We Rate Irish Slot Bonuses 

With so many casino bonuses around, we developed a method to sort the bad from the good and the good from the great. Here’s a bit about our review process:

1. First, we sign up for an account at a casino site and claim their welcome bonus just to see how easy it is.
2. We inspect the slot bonus terms and compare them to similar offers online. Most importantly, we check the number of online casino payment methods. The more players that can be included, the better.
3. Legitimacy is at the heart of our recommendations. We only review Irish casinos regulated by the United Kingdom Gambling Commission (UKGC) or the Malta Gaming Authority (MGA). The Gambling Regulatory Authority of Ireland (GRAI) is set to regulate online gambling in Ireland in 2024.
4. Finally, we give slot sites bonus points for features like no-deposit and no-wagering bonuses.
