What is a Casino Bonus?

As I mentioned, there are a crazy number of different online casinos out there, so it can be difficult for a new casino to stand out. Many online casinos will offer sign-up bonuses or special welcome offers that lure in new users. Generally, casino bonuses come in the form of extra funds that you can use to play games or “free spins”, which allow you to play online slots for free.

Casino competition can be pretty fierce, so you’d be surprised just how attractive some casino bonuses are!

These offers range from just a couple of free spins to hundreds of euros. Additionally, an online casino may offer several different types of bonuses, such as:

• No Deposit Bonuses
• Deposit Bonuses
• Free Spins
• Cashback
• Reload bonuses

How to Find the Best Casino Bonuses in Ireland 

Most online casinos offer some sort of casino bonus, and with so many options out there, it can be pretty difficult to determine which bonuses are the “best”. In this section, I will reveal the methods and criteria I use to find the best Irish casino bonuses. This will give you all the tools to pin down good offers on your own!

1. KNOW THE DIFFERENT TYPES OF BONUSES

Many online casinos will assume that users don’t know much about casino bonuses, so it is imperative to do your research and know what to look for. Casino bonuses are not all created equal, and some have much higher values than others. Here are the different types of casino bonuses you need to know about.

• Welcome Offers: These are the most common bonuses that Irish online casinos provide. Designed to welcome in new players, these packages will typically include some combination of a dollar amount deposit bonus, free spins, and cashback.
• No Deposit Bonuses: These are risk-free bonuses that casinos will offer new players as a type of “try before you buy” promotion. No deposit bonuses are like a trial period for online casinos since you won’t have to deposit any money first.
• Deposit Bonuses: While you will have to deposit money into the account to unlock these bonuses, they generally have a much higher value.
• Free Spins: Free spins are a super common type of casino bonus for Irish sites. You’ll normally get these as small prizes for playing regularly.
• Cashback Bonuses: These are designed to reimburse you for a percentage of your losses. Most casinos will offer you a one-time cashback token (usually for 10% of your daily losses). Others may offer more cashback, especially if you top up your account with cryptocurrency.
• VIP Programs: Casino VIP programs in Ireland target loyal customers and are generally offered to high-roller who play through a singular platform for an extended period.

2. LOOK FOR ONGOING PROMOTIONS

Welcome bonuses are a top draw to get new punters signing up at Irish casinos, but they’re usually just a one-off deal. Once you’ve claimed it, that’s that! But don’t worry; plenty of online casinos keep the good stuff coming with other promos beyond your first deposit – think weekly perks or VIP clubs with loads of extras for the regulars.

3. WAGERING REQUIREMENTS MATTER!

Wagering requirements are an extremely important metric to pay attention to when choosing an online casino bonus. The wagering requirement dictates how much money you will need to actually bet to claim the bonus amount. For example, if the site offers a €2,000 bonus with a 30x wagering bonus, you’ll need to wager €60,000 in order to unlock the bonus. So, in order to maximize the value of the bonus, look for lower wagering requirements.

Here is a table breaking down some different common wagering requirements in Irish casinos.

4. PAY ATTENTION TO THE MAX BET AMOUNT AND BONUS VALIDITY

When hunting for the best casino bonuses in Ireland, keep an eye on the max bet limit and how long the bonus is valid. Even with a cracking bonus lined up, some sneaky terms could catch you out. Casinos with fair terms are the ones you can rely on for payouts, so always give the fine print a proper read to make sure you’re in for the real deal.

5. RESEARCH CASINOS AND READ REVIEWS

There are loads of casino sites out there, but not all of them are on the up and up. I’d recommend checking out forums like Reddit and having a gander at verified customer reviews to be sure the site’s legit. Good news for you—I’ve done most of the hard graft already and personally tested every Irish casino bonus on this list! Still, it’s smart to double-check. Customer reviews are gold for doing your due diligence, and my go-to spots for honest feedback are Trustpilot, Reddit, and a few casino Facebook groups.

6. HOW EASY IS IT TO WITHDRAW FUNDS?

It’s key to check how easy it’ll be to cash out your winnings. Imagine hitting the jackpot only to find you’ve got a 20-step saga just to get your hands on the cash—pure hassle! Most Irish casinos I’ve tried for this list keep it straightforward, with popular options like PayPal, Revolut, and more. So, when you’re picking a casino, make sure they’ve got those handy withdrawal options in place.

7. WHO ARE THE GAME DEVELOPERS?

Plenty of casino sites can cut corners on game quality, leaving you with glitchy slots and games that are anything but a laugh to play. That’s why it’s worth checking the game developers behind the scenes before diving in for a bonus. Top-notch names like Microgaming and NetEnt guarantee smooth gameplay and fun, and plenty of the sites in this list are powered by these legends.

8. IS THE CUSTOMER SUPPORT RELIABLE?

With anything involving money, it is super important to have a helpful and efficient customer support team available. All of the casinos that I have mentioned in this article have live chat customer support agents available that will quickly answer your queries and help you with any issues you have on your casino account.

9. APP AND MOBILE USER EXPERIENCE

Mobile-friendly casinos are the latest trend and are quickly becoming crowd favorites. Since loads of us prefer gaming on our phones, it’s essential that casino sites invest in top-notch apps or mobile-friendly experiences. When hunting down the best casino bonus in Ireland, have a peek at the mobile site or app quality—more and more players are drawn in by a smooth mobile setup.

LEGALITY OF CASINO BONUSES IN IRELAND

One of the first things you should check before signing up for a new online casino in Ireland is whether or not the specific casino is licensed in Ireland. While online gambling is completely legal in Ireland, you’ll need to ensure the casino is allowed to operate in the country. 

Online and physical casinos in Ireland are regulated by the GRAI (Gambling Regulatory Authority in Ireland). For decades, gambling sites in Ireland have run in somewhat of a grey area as it was fairly unregulated. But, with the GRAI’s formation in 2022, online gambling casinos will now be properly monitored, licensed, and regulated in Ireland.

Questions to Ask Yourself Before Choosing An Irish Casino Bonus

Ready to go ahead and sign up for a welcome offer on a new online casino? Here are a few final questions to ask yourself before you make the leap

WHAT KIND OF GAMES DO YOU GENERALLY PLAY?

Some casino sites will have a huge number of games available that you can play to claim your bonus. But others will offer a better contribution rate for slots than for games like blackjack and poker. For example, a site may have a 100% contribution rate for slots and only a 50% contribution rate for blackjack. So, if you prefer playing blackjack, only 50% of your wagers will count towards your bonus. Make sure to check the terms of your casino bonus to ensure the games you want to play are included!

HOW MUCH MONEY ARE YOU WILLING TO RISK?

When choosing a casino bonus in Ireland, it is crucial to pay close attention to the wager requirements and minimum deposits. If you only want to bet a small amount but sign up for a bonus with a 40x wagering requirement, you’ll soon realize how much money you are expected to wager. Check the wagering requirements before you sign up for a bonus and calculate how much you will need to bet in order to unlock the prize money. You should also stay organized and manage your bankroll by keeping detailed records of how much money you are wagering. 

WHAT KIND OF CASINO BONUS ARE YOU LOOKING FOR?

The final question to ask yourself before committing to a bonus is, “What type of bonus are you after?”

If you have a lower budget but just want some free spins and maybe a small welcome package, you should look at no-deposit or low-deposit bonuses. If you are willing to wager big bucks for a large bonus value, then you should look at high-value casino bonuses. 

The bottom line here is that before you dive into a new casino bonus, you should know: What type of game you can play, how much money you’ll need to wager, and the type of bonus (deposit, no deposit, free spins, etc.)

Tips for Getting the Most Out of Online Casino Bonuses in Ireland

Often the advertised bonus amount is not what you’ll actually get but instead the maximum possible bonus. Let’s go over some tips for maximizing your casino bonus and getting the most from your sign up offer.

• Read the fine print: I know it is a bit tedious, but you should always read the terms and conditions before you embark on your Irish casino bonus journey. There’s no sense in accepting an epic €2,000 welcome bonus if the wagering requirements are 40x and you aren’t willing to bet €80,000. Also, the fine print will often tell you how long you have in order to complete the bonus.
• Check the “Promotions” page regularly: Irish online casinos will almost always have a “promos” tab on their sites that list out all of the welcome offers and ongoing bonuses. Checking this page often can ensure you don’t miss out on any bonuses.
• Play games with high contribution rates: Check which games in your bonus have 100% contribution rates and only stick to these games or other games with relatively high rates. Generally, games like blackjack and poker will be excluded from the offer or will only have a 50% contribution rate. 
• Manage your bankroll: Gambling can quickly get out of hand if you are not careful, so it is important to manage your bankroll effectively to prevent yourself from wagering too much. I recommend putting aside the funds you are willing to lose and only signing up for bonuses with wagering requirements less than this amount.
• Take advantage of free spins: I recommend using any free spins from your welcome offers early so that you can use your winnings to meet the playthrough requirements.
• Go above the minimum deposit: This obviously only works if you have the budget for it, but if you want to maximize your winnings, you would deposit and wager a higher amount than the minimum deposit in order to get the largest bonus possible.
• Contact customer support for bonus extensions: Some casinos will offer you extensions on your bonus validity period or match increases if you’re just short of completing the rollover. It doesn’t hurt to contact support and make a polite request.
• Focus on more than the welcome bonus: Irish casinos will typically offer many more bonuses than just the simple welcome offer. For example, you may be able to get weekly free spins, cashback, VIP programs, and more ongoing deposit bonuses.

Options for Withdrawing and Depositing for Irish Casinos

Withdrawing and depositing at Irish casinos is all about finding the methods that suit you best. Whether you’re topping up your account or cashing out those winnings, having plenty of fast, secure options is key. Here are some popular payment methods at Irish online casinos, perfect for all your gaming needs.

How to Claim Casino Bonuses at an Irish Casino

After deciding which Irish casino bonus is the best option for you, it is time to actually sign up and start working toward the bonus. Here is my step-by-step guide for claiming your casino bonus in Ireland.

Terms and Conditions of Irish Casino Bonuses

I know I probably sound like a broken record, but I really can’t stress enough how important it is to check and double-check the terms and conditions of your casino bonus. Here are some of the most important things to review:

• Minimum deposit: This is the minimum amount you must deposit to claim the bonus. For example, if the minimum deposit is €20, you must deposit €20 to access the bonus.
• Wagering requirements: These specify the number of times you must play through a bonus before converting winnings into withdrawable cash. Wagering requirements vary across casinos and bonuses. Some top Irish casinos have lower wagering requirements. It’s essential to read the T&Cs to understand what is needed before you can withdraw your money.
• Time limit: Check the expiry date of your bonus, including welcome bonuses. If you do not claim or meet the wagering requirements before the bonus expires, you will lose the bonus.
• Specified restrictions: Be aware of any restrictions, such as those related to payment methods or geographic location, that might apply to the casino bonus.
• Eligibility: For example, Irish players might be eligible for a no deposit free spins bonus on a specific slot game chosen by the casino. This also applies to live dealer bonuses.
• Player type: The terms and conditions will specify who can claim the bonus. Welcome bonuses, for instance, are typically available only to new players creating a casino account for the first time.
• Win cap: This is the maximum amount of real money a player can win when using one of the casino’s bonuses.
