How 600% Casino Bonuses Work
Whenever you come across a 600% casino bonus at an online casino in Ireland, it will be as a welcome bonus. They are designed to entice new players to the casinos offering them, and by giving you 6 times the money you deposit to play games with, they are very successful. When you do find one, you’ll need to snap it up quickly, as it will only be available for a short time. But before you do, it’s a good idea to understand how they work.
Different Types of 600% Casino Welcome Bonuses
Irish players who gamble at online casinos regularly have access to a wide range of bonuses they can claim. The online casinos listed at Hareslots include cashback bonuses, birthday bonuses, refer a friend bonuses and various weekly promotions. These can all be claimed by players who have already registered with the casinos making the offers. And then, there are welcome bonuses. These can only be claimed by new players who have yet to register an account with the site offering the deal.
600% Matched Deposit Welcome Bonuses
The casinos offering a 600% casino welcome bonus will match the money you deposit 600% up to a specified maximum. Since the offer is so generous, the maximum is typically kept low. Online casinos in Ireland can’t afford to give away free money too often, so typically, it might be a 600% casino bonus up to 140 Euro. That’s your original deposit, plus a 6x match – (mathematically 6 x 20 = 120 + 20 = 140).
📙 Erik King’s Quick Tip: Some 600% bonuses quietly round down your match if your deposit isn’t a clean multiple of 10. To avoid losing bonus value to rounding errors, always deposit amounts like €20, €30 or €50, never odd figures like €23 or €37.
600% Welcome Bonus plus Free Spins
Another option that casinos turn to is to add free spins on specified slots, so you might see something like – 600% bonus up to 140 Euros plus 50 free spins on Sweet Bonanza. In my opinion, this is an even better deal because, in effect, it gives you even more free bonus money (albeit in the form of free spins). You’ll find plenty of offers like this on the free slots page at Hareslots.
600% Reload Welcome Bonus
With this type of bonus, the 600% match won’t apply to all of the reload elements. If it did, the casinos offering the deal would soon go broke. So, what casinos normally do in this instance is to offer smaller percentage matches with each of the deposits, but when you add them all up, they total 600%. I don’t think it’s sneaky. It proves what I always say: always read the bonus offer’s terms and conditions carefully before claiming any deal.
No Deposit 600% Welcome Bonuses
This type of bonus is super rare. But they do occasionally appear. I should warn you though, they are not quite what you might imagine. They are usually like reload bonuses, but it’s only the initial deposit that doesn’t require any money. The reload deposit does. Hareslots lists genuine no deposit bonuses.
Low Deposit 600% Welcome Bonuses
There are many low deposit casinos listed at Hareslots. They specialise in offering welcome bonuses with deposits from 1, 2, 3, or 5 Euro. I must say that the number of slots or spins you’ll be able to play are on the somewhat low side. Having said that, I frequently come across low deposit bonuses with up to 50 or even 100 spins.
📙 Erik King’s Quick Tip: Some low deposit 600% bonuses don’t scale spins linearly, a €1 deposit might trigger 20 spins, while €2 still gives 20. Always test small increments before committing, you might find a deposit “sweet spot” that maximizes spins per euro.
Minimum Deposit Bonuses
Apart from no and low deposit bonus offers, all casinos offer minimum deposits on their bonuses. It’s often highlighted in bonus adverts to attract your attention. There is just one thing I should warn you about with minimum deposits, and it is that it might not trigger the free spins that are part of the deal. It’s another instance of why it pays to read a bonus offer’s terms and conditions carefully.

Bonus Terms and Conditions and How They Affect Bonuses
Did you know that bonus offer terms and conditions differ from a casino’s general terms and conditions? They do, and the clauses they contain should guide your decision on which bonus suits you best. It’s why I am always going on about checking bonus offer terms and conditions before claiming a deal – even if it is one of the many no deposit bonus codes listed at Hareslots. If wagering conditions are too high, or the minimum amount of winnings that you can withdraw is unfavourable, you might want to go with another offer.
The Easiest Way to Find and Compare Casino Bonus Offers
Hareslots make it easy to find and compare different bonuses, by listing bonus types on the same page. There’s a page for live dealer casinos and bonuses at Hareslots, and a page for crypto casinos. Hareslots also has a page for new online casinos. Each page shows a selection of the bonuses you can claim, making the comparison exercise so much easier.
Software Providers Should Influence Your Decision, Too
The thing that makes all slots stand out from each other and makes some better and more rewarding to play than others, is the effort and creativity of the software providers.
If you have a favourite software provider, you might centre your choice on that provider’s games if you see them offered with a bonus.
You might prefer a bonus that gives you 100 free spins on a slot like Sweet Bonanza by Pragmatic Play, or Aviator, one of the newer crash games by Spribe. Alternatively, you might prefer a bonus linked to a selection of games from one provider, like NetEnt, or BGaming.
The only thing I should warn you about if you’re looking forward to a long session of free spins on a specific slot, is they are often eked out in smaller quantities over several days. You still get just as many spins, just not all at once.
📙 Erik King’s Quick Tip: When free spins are drip-fed over days, some providers randomize RTP per session. If your first day’s spins are cold, wait 24 hours before using the next batch, the RTP seed may reset daily, giving you better odds later in the cycle.
My Tips for Getting the Most From your Bonus
Playing bonuses is always fun, but it can be even more enjoyable if you follow the tips I am about to give you to heighten your experience.
- Choose slots with a low or low-to-medium volatility rating. You can wait for ages for high volatility slots to payout, whereas with lower volatility games they payout often, albeit in smaller amounts. The more winning lines you get the more chances you will have to play more spins and try to win bigger prizes.
- Look for games with RTP percentages of 95% or higher. RTP is accurate over tens of thousands of spins rather than just a few hundred. However, all slot play is randomised by Random Number Generators (RNGs), so the fact of the matter is that you cannot predict the outcome of any spin with certainty.
- Choose the amount you wager per spin according to the generosity of the bonus. Smaller wagers per spin will give you more spins, which is important with less generous bonuses. It’s not so important with bigger bonuses that provide you with lots of free play.
- When you land a winning line, it’s safer to collect the winnings rather than gambling them if the machine gives you the option to do so. It’s the ‘a bird in the hand is worth two in the bush’ approach.
- Use bonuses to play games you haven’t played before with real money, but only after you’ve played a free, demo version first, or a version available via one of the many no deposit bonus codes you’ll find at Hareslots. That way, you learn the ropes at no cost.
Claiming a Bonus and Withdrawing Your Winnings
I hope you will find my tips helpful. Once you’ve found a bonus you like at Hareslots, this is how to claim it:
- Click on the green ‘CLAIM BONUS’ button.
- When you see the registration form, enter the personal details requested, typically your name, address, and date of birth, your email address and your mobile number.
- Create a username and password.
- Select the currency you want to use and a payment method from the dropdown boxes.
- Enter the amount you want to deposit.
- Click ‘Confirm’.
To confirm your new player account, the casino may send a link to your email address of mobile device. If they do, click on it and your account will be confirmed. The entire process usually takes less than two minutes to complete.
When withdrawing your winning from a bonus, you first need to ascertain you’ve met all of the bonus offer’s terms and conditions. If you have, here’s what to do next.
- Navigate your way to the platform’s cashier page.
- Choose the ‘Withdraw’ option.
- Enter the amount you wish to withdraw.
- Confirm the payment method you’re using.
- Click ‘Confirm’.
Online casinos always reserve the right to verify your identity. You’ll normally be asked to send a copy photo ID (typically a driving licence or passport) and a recent utility bill showing your address.
Warning – Only Use Properly Licensed Online Casinos
I cannot stress strongly enough the importance of casino licensing. It underpins the whole safe online casino gambling scenario and is especially important when claiming a bonus from a new casino. void using any site that isn’t properly licensed.
You’ll usually find information about a casino’s licence at the bottom of the site’s landing page. Look for licences issued by agencies such as the Malta Gaming Authority, the UK Gambling Commission, the Kahnawake Gaming Commission, and the eGaming department of the Curacao government.
Mobile platforms should also operate under a recognised gambling licence. Some Irish players prefer to download a mobile app. You find some useful casino app information at Hareslots.
