How to choose the best online casino bonus?
As you’d expect, the best casino bonus depends on what kind of player you are and what you’re after. Online casinos offer a huge variety of bonuses, many with eye-catching amounts to grab your attention, but not all of them will suit everyone.
The best bonus for you depends on how you like to play, your budget, and your favourite games.
Have a read through this article to learn more about your options and find the best one for you.
Once you understand your options, the next step is finding a bonus that suits you from one of the many new or older active and licensed casinos on the online market in Ireland. That’s where we come in, with excellent bonus recommendations from reputable casinos.
Our recommendations consider both the quality of the offers and their terms, and we carefully review the fine print (as we recommend you do as well before activating a bonus, as it also entails certain obligations before you are allowed to withdraw your winnings).
💡 Tip: The smartest players don’t just choose the biggest bonus, they match bonus structure to their risk profile. If you’re a cautious player, look for offers with lower match percentages but lower wagering requirements (like 100% at 20x). High-risk players target large bonuses with high wagering (like 400% at 40x) but only if the max cashout is uncapped. Matching the right bonus type to your playstyle is how insiders stretch real value from promos.
Types of Irish casino bonuses explained
Most casinos dish out a range of bonuses to keep players interested.
- If you’re thinking of signing up, no deposit bonuses or welcome bonuses that require a deposit are common offers.
- Players who prefer specific types of games, like live casino, slots, or table games.
- Regular players looking for a bit of an incentive to top up their balance (deposit bonus).
Below I’ll explain some of the main types of bonuses that can be found on the casino bonuses page of an online casino in Ireland or anywhere else in the world.
Welcome bonus
This is the most common type of bonus offered to new players who decide to make a deposit at the casino.

In return, the casino offers an additional amount to play with, often doubling or tripling the money deposited (bonuses of 100% up to 200% are quite common). The bonus may also come with free spins on a particular slot or other types of rewards.
You’ll probably need to deposit a minimum amount to claim the bonus, and there’s usually a time limit on using your bonus funds or meeting the wagering requirements.
No deposit bonuses
They’re not as common, and they’re usually fairly small, but they’re a handy way to test the waters at a new online casino.
By simply registering at the casino, you can receive an amount of money to play with, free spins on slots, or free playing time.
The terms and conditions tend to be very restrictive, and the amount that can be withdrawn is small (if withdrawal is allowed at all).
The takeaway for these no deposit casino bonuses would be that they are not meant as a get-rich-quick method with zero risk for the player. They are designed to persuade you to make a new account at that casino, and the terms of the offer are such that you cannot withdraw large amounts.
Deposit bonuses
Deposit bonuses cater to both new and existing players, with welcome offers typically granting higher percentages than reload bonuses. For example, Unibet Casino provides generous first-deposit matches, often reaching 100%, while platforms like PrimeBetz Casino offer reload bonuses at a slightly lower percentage to encourage ongoing play. Some casinos, such as SlotLords Casino, schedule these bonuses on specific days, giving players incentives to deposit regularly. While welcome bonuses may double a player’s initial deposit, reload bonuses usually fall below 100%, often ranging between 25% and 75%, depending on the promotion.
Free spins
Free spins can be the main reward or an extra perk alongside bonus funds. Many casinos, like Cosmo Casino, structure their free spin promotions over several days, requiring players to return daily to claim a set number of spins. At Ritzo Casino, for instance, a welcome package might grant 100 free spins, split into 10 spins per day over 10 days. These offers are also frequently included in no deposit bonuses, as seen at 777 Casino, where players can receive spins upon registration.
However, casinos determine the bet size for these spins, and it’s typically low, often set at €0.10 per spin, limiting potential winnings unless bonus terms include multipliers or special payout boosts.
💡 Tip: When free spins are drip-fed over several days, savvy players check if unused spins expire daily or accumulate. If they expire, always play them late at night before reset, fewer players online means reduced server load, which can actually speed up spin animations and allow faster playthrough, crucial if you’re also on a time-limited wagering schedule.
Cashback
Cashback promotions return a percentage of losses to players, typically ranging from 10% to 20%. At Just Casino, regular players can benefit from weekly cashback, with the percentage depending on their VIP level. Similarly, Nuggetslots Casino provides cashback on specific game categories, such as live dealer games or high-stakes slots.
These offers always come with conditions, including minimum loss thresholds or wagering requirements before withdrawal. Lucky Hunter Casino, for example, may require cashback funds to be wagered once before they can be cashed out. Checking the terms beforehand ensures you know exactly how and when you can use the refunded amount.
Other types of bonuses
Casinos often introduce creative bonuses to reward loyal players. At Cashed Casino, members can accumulate loyalty points that convert into cash or free spins, while Boomerang Casino offers exclusive perks such as higher withdrawal limits and personal account managers. Some platforms, like King Casino, take it further by granting contest tickets for prize draws, which can include luxury trips or high-value electronics.
These promotions vary widely, with some focusing on ongoing rewards and others tied to seasonal or event-based campaigns. Checking a casino’s promotional calendar can reveal limited-time offers that provide unique incentives beyond typical deposit matches and cashback deals.
Under the terms and conditions of the offer
Now that we’ve seen some of the types of bonuses that are more common at online casinos in Ireland and abroad let’s take a closer look at the things you should consider before accepting them.
Often, the most attractive offers are also the worst deals for players, depending on the various restrictions imposed by the terms and conditions attached.
Below, we discuss some of these conditions which are common to most casino bonuses.
Wagering requirements: in the vast majority of promotional offers available at casinos, you will be asked to meet certain wagering requirements before you are allowed to withdraw your winnings.
You’ll find them mentioned in the terms and conditions of the offer, in the form of a number that tells you how many times the bonus must be rolled, the amount won, or both.
An example would be the case of a 200% bonus, which gives you 100 Euro when you deposit 50 Euro. In order to be allowed to withdraw your winnings (not the amount received as a bonus) you may be asked to run that bonus 40 times. So, you will have to make bets of 4000 Euro in this example, and the amount you can bet will have to be within certain limits and only on some of the casino games.
Game restrictions: certain bonuses are limited to specific games, and some games may be restricted when you try to meet the wagering requirements. The terms will tell you exactly which categories of games are allowed and whether any of them are restricted.
If you still play those games with the bonus money, you may lose any winnings you’ve earned in addition to the amount you received through that promotion.
Restrictions may also apply when it comes to the amounts that can be used for betting. When you have a requirement to spin 4000 Euro in bets of a maximum of 10 Euro, this means that you will need a minimum of 400 spins to fulfil the requirement.
Time limits: don’t neglect the time limits you have to stick to. Initially, when you get the bonus, there will be a time limit in terms of the hours or days you can use free spins or free play time. For the amounts received, the times are generally in the order of weeks, 30 days maximum.
You’ll only have a short window to meet the wagering requirements, usually a week or two. If you don’t fulfill the requirements, the entire bonus amount you’ve won can be taken away.
The amounts that can be withdrawn: very often, you will also discover restrictions on the amounts that can be withdrawn if the winnings result from bonuses offered by the casino. Particularly with no deposit bonuses, there will be very low limits on the amounts that can be withdrawn after fulfilling the wagering requirements.
Accepted payment methods: many bonuses can only be earned when using certain payment methods. Again, it is mentioned in the terms if there are such restrictions. They can apply to both deposits and withdrawals.
Some casinos push certain payment methods and only give bonuses to players who use them.
In general, there will be a minimum deposit amount that will have to be used.
How to find and compare the best casino bonuses
For a full list of online casinos that are allowed to operate in Ireland, you can visit the official website of the GRAI (National Gambling Office). There are dozens of such casinos, and new sites are launched every year.
Wading through all these casinos and comparing their offers isn’t exactly a walk in the park. It requires time and knowledge, including how trustworthy these companies are, what their customer relations department is like, and many other criteria that should be taken into account.
This is where our offer comes in. On this page, and in general on our website, you will find lists of recommended casinos, depending on what you need.
We recommend several options for the best casino bonuses in Ireland. We analyzed the terms and conditions of the offers, and they are good enough to be recommended. Of course, it’s a good idea to read the terms and conditions yourself before accepting an offer to know exactly what you’re getting yourself into.
💡 Tip: When comparing bonuses, experienced players use a metric called effective cashout potential, a mix of bonus size, wagering requirement, max bet rule, and cashout cap. A smaller bonus with 20x wagering and no withdrawal limit often beats a huge 500% bonus capped at €100. Use a spreadsheet or bonus calculator to weigh value realistically, not just based on headline numbers.
Tips for maximizing the benefits of these bonuses
Knowing exactly what a casino bonus’s limits are is essential to getting the most out of it. This is where knowing the terms and conditions of the offer comes in. Then comes the attempt to get the most out of the bonus and, if possible, to withdraw some of the profit.
- Only go for bonuses that suit the games you actually like playing. A bonus offered in the live casino section might not be useful if you just want to play slots. There are plenty of bonuses to choose from, there’s no need to accept everything in front of you.
- If you are unsure about a casino, it may be a good idea to use a no deposit bonus, possibly with free spins, to test it out.
- Play free slots before you put money into them. Before you bet on a new slot, look for its free version. The developers offer this option, and the game is identical to the one in the casino (it’s a legal requirement that free slots be identical to pay slots).
- Make sure you meet the wagering requirements within the bonus terms. Use the highest bet you are allowed to use to reduce the number of spins required. The limits will be quite low anyway.
How License and Regulations Influence Bonus Offers
The online gambling market in Ireland is constantly growing, and new casinos appear every year. They will try to attract new players from other casinos, so they will have attractive promotional offers to achieve this. The promotional budget tends to be a little more generous in this first phase as casinos try to get as big a slice as possible of the market in Ireland.
Although the new casinos do not yet have a well-established reputation, it is still important to note that they have a license obtained for Ireland and that they have certain obligations regarding player protection.
The license, for which they pay quite a lot each year, also requires them to behave in a certain way regarding the bonuses on offer.
National regulations may limit the wagering requirements to make them more bearable or limit the bonuses that can be earned. Certain types of bonuses may even be banned altogether.
Information about the terms and conditions of bonuses must be clearly displayed and easy for players to understand.
Getting a bonus at online casinos, step-by-step
Bonuses are easy to find, as every online casino has them on offer. However, it will be a bit more difficult to choose just one of them, the best one possible for your situation. For beginners, we have a short guide below with the steps you need to take to get a bonus.
- Choose a bonus that suits you from a respectable casino. Either search for these bonuses directly or go through us and choose from our recommended casinos. The welcome bonuses are generous, and the recommended casinos are reliable.
- Register at that casino. Follow the link we provided and visit the casino, then fill in the registration form with the necessary personal details. Casinos need to verify your identity and will ask for your full name, email address, phone number, and other details. You will need to confirm the details you have given.
- Get your welcome bonus. The method varies depending on the bonus. Some are registration only, with no deposit, while others require a deposit and the use of a code or contacting the support department.
- Use the amount received to cover your wagering requirements. Make sure you only play permitted games, with bets of an amount that is accepted, and complete the requirements in the time given.
- Withdraw the amount you win if you make a profit after fulfilling the wagering requirements.
