What to Look for Choosing a Casino Bonus
In addition to no deposit bonuses, there are many different types of casino bonuses on offer in Ireland. They include matched welcome bonus offers and many other types of bonuses with promo codes. To find the best deals, bookmark Hareslots and check back regularly for updates.
The online casino gambling scene in Ireland has never been more vibrant, and it’s growing in popularity by the day. Find out what the excitement is all about by picking one of the many top casino bonus offers I recommend here at Hareslots.
There are literally thousands of online casinos on the World Wide Web. Some are better than others, and some are downright scams. Hareslots was formed to help Irish players find the best, safest online platforms that offer great online gambling experiences in a safe, secure environment. Hareslots does that by putting all the casino sites listed through an exhaustive checking procedure before recommending them. It’s a key part of my job at Hareslots, and what follows below is what I check out on your behalf.
Online Casino Bonus Offers
Ireland’s online gambling scene is among the most dynamic in the world. It is an extremely competitive marketplace, made even more so by the hundreds of online casino bonuses being offered by both long-established and newly launched online casinos. There are so many that it can be quite difficult to know which ones to choose. That’s why Hareslots was created, to list only the best of the best. Also, the way that each type of bonus works is explained on Hareslots, enabling you to make informed decisions as to which bonuses suit you best.
Online Casino Welcome Bonuses
All casino sites offer welcome bonuses. As shown below, there are several types of welcome bonuses, but the most common and the biggest value-wise are matched deposit bonuses. It is quite usual to see 100% casino bonuses. These are welcome bonuses whereby the online casino in question matches the deposit you make 100%, thereby doubling the money you have to play with. Percentage matches can go even higher.
No Deposit Free Spins Casino Bonuses
Free spins no deposit bonuses are very popular. This type of welcome bonus, as the name suggests, doesn’t require you to make a deposit. All you usually have to do is claim this type of bonus is to register a new player account. Once that’s complete, a set number of spins will be added to your account.
📙 Erik King’s Quick Tip: Right after registration, some casinos preload free spins but don’t activate them until you open the eligible game. If you wait too long, the spins can expire silently. Always launch the target slot immediately after signing up to lock them in.
Free Spins Bonuses
Free spins bonuses are usually another type of welcome bonus, but they can sometimes be offered as loyalty bonuses to regular clients. They are, essentially, like no deposit bonuses. However, free spins are also often added to deposit welcome bonuses too. While you have to make a real money deposit to claim such a bonus, the spins are given as an extra freebie.
Minimum Deposit Bonuses
The next best thing to free no deposit bonuses are low deposit deals. They can come as low as 1 Euro, 2 Euro, 3 Euro, 4 Euro, and 5 Euro deposits. Hareslots also lists minimum deposit casinos where you’ll find these types of bargains.
Free Cash Bonuses
These, too, usually appear as a form of welcome bonus. They do not require a real money deposit, but instead of awarding you free spins, they credit your new player account with free money. This money can only be used to play games, but the games are not limited to slots.
Reload Bonuses
All of the bonuses shown above are welcome bonuses of one sort or another and are specifically designed to attract new players to online casinos in Ireland. But once you register with a new casino, that casino wants to turn you into a loyal player who returns to gamble on their site regularly. That’s what these next bonuses are designed to do.
Reload bonuses are usually matched deposit bonuses and can only be claimed by existing players. They can be quite lucrative, but as with any bonus offer, it’s important to read the bonus terms and conditions carefully. Reload bonuses often include free spins, allowing you to enjoy slots without spending extra.
Cashback Bonuses
Another type of bonus that rewards loyal players only, cashback bonuses give you back a percentage of the money you have lost while playing, usually over a 7-day period.
Bonus Offer Terms and Conditions
Claiming online casino bonuses can be rewarding, but if you don’t read the terms and conditions first, you might encounter some unpleasant surprises. There’s nothing onerous, but you might have to jump through a few hoops before you can claim your winnings. Part of my job at Hareslots is to ensure you have the best gambling experiences possible, so I like to make sure you’re fully aware of what could be involved. Here’s what to look out for when checking the T&Cs.
Wagering Requirements
Most bonuses (of all types) come with wagering requirements. They look like this – x20 or 20X. The “x” is a multiplier, and the number indicates how many times you have to deposit the deposit value of the bonus and playthrough before you can withdraw your winnings. Even if the bonus is no deposit or free spins, the spins have a monetary value and it’s this value that is used to make the calculation.
Some bonuses come with no wagering requirements. If you find one, it’s worth claiming.
Minimum/Maximum Withdrawal Limits
Online casinos cannot afford to give away huge sums of money, so as well as wagering requirements, they set limits on withdrawing winnings from bonuses. They specify a minimum below which you cannot make a withdrawal. They also set a maximum cap on how much you can withdraw. This means you could win, for example, €150 Euro but only be able to withdraw €100.
📙 Erik King’s Quick Tip: Some casinos enforce max withdrawal caps only after wagering is complete, not during. If your bonus win nears the cap, switch to low-volatility games to avoid overshooting and forfeiting the excess.
Time Limits
Time limits are also specified in bonus offer T&Cs. Firstly, there is the period during which the deal can be claimed. Then there is a deadline on how quickly you must play the bonus through. Lastly, there is a deadline for how quickly you must meet any wagering requirement.
Game Choice Restrictions
Some bonuses, especially free and minimum deposit bonuses, specify which games of slot titles can be played.
Top Tips to Help You Find and Compare the Best Online Casino Bonuses
Hareslots lists the best online casinos and casino bonuses available to gamblers in Ireland. All bonuses look good at first glance, but some are better than others. Here are a few tips to help you find the best.
- Look for no deposit bonuses. They allow you to play games for free. They are great for newbie gamblers who want to try online gambling for the first time without spending any money.
- Check out the minimum deposit amounts. Most matched welcome bonus deals specify a minimum deposit amount. Check out the minimum deposit that grants you the House match. It’s basically free money.
- Check out low deposit casinos. Sometimes, low deposit bonuses offer smaller wagering requirements than no deposit deals.
- Choose bonus games with care. Bonuses often specify a game or range of games that can be played. Look for games with low RTPs and low volatility ratings. Low volatility means a game pays out frequently, though in smaller amounts.
- Look out for bonuses offered by new casino sites. These can be quite generous because casinos that have just been launched are trying to establish themselves as quickly as possible. Another good thing about newly launched casinos that welcome gamblers from Ireland is they offer innovative features.
- Pick a no wagering bonus.
- Remember, before you claim a bonus deal, read its specific terms and conditions.
Without a doubt, the best way to find a great online casino bonus offer is to bookmark us here at Hareslots and return regularly for new casino and bonus updates.
How to Get the Best from the Bonus You Choose
The best way to get the best from any bonus you claim is to familiarise yourself with the game before you play it. Gameplay can vary significantly from slot machine to slot machine. That’s why it’s best to play the game in demo mode first. In demo mode, you can play the slot as many times as you like, and it won’t cost you a single cent.
The higher your wager per spin, the quicker your bonus will run out. This is particularly true with no and low deposit deals. To make your bankroll stretch further:
- Select smaller coin values.
- Choose smaller bet sizes
- In a game with variable paylines, the higher you go, the more chances of winning.
- Never play under the influence.
The more playlines a slot has, the better. Look for bonuses that can be used to play MegaWays slots. They offer from 64 up to 117,649 ways to win.
By the way, you don’t have to bother with searching for links to free slots. You can play them directly at Hareslots.
📙 Erik King’s Quick Tip: Some casinos don’t cap wins in demo mode and track your play data to personalize future bonus offers. If you hit big in demo, wait 24–48 hours before claiming a bonus, you might trigger a better promo targeted at “potential whales.”
How Software Providers Influence Online Gambling
The online gambling industry wouldn’t exist without its infrastructure, which comprises several component parts. This includes online casino networks, licensing agencies, bonus code websites, and review platforms. One of the best of these, serving gamblers from Ireland, is us here at Hareslots. However, the foundation of online gambling is the network of software providers. They are the teams behind the design and creation of online games. Without them, online gambling as we know it today simply wouldn’t exist.
Software providers define all of the parameters of a game. These include its features, the number of reels and paylines, the game RTP and volatility ratings, and its payout sizes, all of which define how the game performed in any given bonus. Casinos compile their individual game libraries depending on which software providers they partner with. They also determine how much you can win by playing a bonus, not by influencing how the game plays or performs, but by the restrictions and limits they impose through their terms and conditions.
So, it’s all down to the software provider. The biggest and most innovative include Microgaming, NetEnt, Play’n GO, and Playtech. Evolution Gaming is the world’s leading software provider when it comes to live dealer casinos and the live games they offer.
Software providers have also led the revolution in being able to gamble via mobile devices. They’ve ensured that all of their games are now available in HTML5, which means they can be played through any browser, including mobiles. They also commissioned the casino app. They are available for Android and iOS-driven mobile devices, and free versions are available for download from many Irish online casinos.
Step-by-Step Instructions on How to Claim Irish Online Casino Bonuses
Claiming online bonuses for Irish players is pretty much the same whichever casino you’re claiming the deal from. There are slight variations, but in the main, the steps are as follows:
- Choose your bonus from those listed on Hareslots. Why? Not only is it easy to compare the casinos and bonuses from the reviews we provide, but we’ve also pre-checked everything to ensure they are safe and secure.
- Hareslots lists no-deposit bonus codes. If your chosen bonus has one of these, be sure to note it.
- Click on the deal from the Hareslots list and you’ll automatically be transferred to the website of the casino offering the deal.
- Click on the ‘Register’ or ‘Sign Up’ button. This will take you to the new player account registration page.
- Create a username and password.
- Provide the requested details, including your date of birth, name, postal address, email, and mobile number.
- If necessary, enter the bonus code.
- Choose your preferred currency and payment method.
- Enter the amount you are depositing, if applicable.
- Click ‘Confirm’.
Some of the newer Irish online casinos have a shorter, simplified sign-up process.
If you are one of the many Irish players who win money from the bonuses they claim, here’s how to go about making a withdrawal.
- Navigate your way to the cashier page.
- Select “Withdraw.”
- Confirm the currency and payment method you wish to use.
- Enter the amount you wish to withdraw.
- Click “Confirm.”
If you have complied with all of the terms and conditions, you should receive your money shortly. Some Irish online casinos offer instant withdrawals, while some might take 3 to 5 days, especially if you have to complete the KYC procedure.
Frequently Asked Questions
Yes, you can. But if you want to withdraw your winnings, make sure that the bonus you choose is ‘non-sticky.’ Also, you must use the same payment method for withdrawing as you did for depositing. You must also ensure you have complied with the offer’s terms and conditions.
