100 Free Spins No Deposit
You’ll usually need to deposit and spend real cash when you want to play top online casino slot games, but there are some exceptions. You might be able to find a casino site that offers a 100 free spins promo so you can enjoy the game without the risk of losing any real cash. This is a great way to try out a new online casino site, or experience a game you might not have played otherwise.
Getting 100 spins totally for free isn’t as difficult as it may sound. All you need to do is sign up at one of the sites we recommend on this page. We’ve done our research and not only do these casinos offer 100 free spins promos, but they also have a fantastic overall experience from games to mobile experience and everything in between.
It’s worth noting that while some online casinos hand out 100 free spins no deposit offers, these promos tend to come with strict terms and conditions. For example, there might be very high wagering requirements, or low win limits. A way around this is to claim 100 free spins deposit bonuses, where you’ll need to top up your casino account with a certain amount of money before you can claim the promo.
If you want to bag your online casino 100 free spins offer right now, just sign up at one of these sites via a link on this page at Bookies.com as this is the only way we can make sure you’re actually eligible for the generous offers that we mention. We have some exclusive promos so if you don’t sign up via our links, you might not get the 100 free spins.
100 Free Spins Sign Up Bonus Offers
As we mentioned, we’ve put together a list of all online casinos where you can bag yourself lots of free spins. Rather than 100 free spins no deposit, Ireland players might need to top up their accounts with a small amount of money (for example €10) to get the offer, so it’s important to take a quick look at the T&Cs before you claim.
Dublin Bet Casino
This is an online casino made specifically for players in Ireland, and it shows. The range of slot games is excellent, featuring new releases like Trial of Phoenix and Yummy Dumplings Hold the Spin, as well as popular online slots like Big Bass Bonanza and 3 Coin Volcanoes.

Casino Bonus 100 Free Spins Offer Types
While 100 free spins no deposit bonuses might be the best possible type of offer, there are a few different variations of free spins bonuses that you might find at Irish online casinos. For example, some promos ask for bonus codes, while other casinos require you to make a deposit of a certain amount in order to get the free spins. These are some of the common types of promos you might see.
100 Free Spins Slots No Deposit
Do you want to play top slot games totally for free? A 100 free spins no deposit offer is the best way to do that. These special promos do exactly what they sound like - they award you with free rounds on a top game and you don’t need to make a deposit to claim.
You simply get 100 free spins straight into your new account as soon as you sign up, and you can use them on valid games for your chance to bag a real money win. No deposit free spins offers aren’t limited to new users either - in some cases existing customers can also claim these special promos just for logging in during the promo period.
100 Free Spins Deposit Bonus
You might notice that a 100 free spins deposit bonus is a lot more common than a no deposit offer. This makes sense since 100 free spins is a lot, so you can’t blame the casino for wanting at least a small deposit from you first.
These offers are very easy to claim and usually just requires you opting in and entering the casino promo codes if required, or choosing the offer when you’re making your deposit. The free spins are usually credited to your account immediately so you can go off and use them on the valid game or games.
100 Free Spins On Sign Up
A 100 free spins sign up bonus is a special type of no deposit bonus given to brand new online casino players. The great thing about these promos is that you don’t need to do anything special at all to get them as they’ll usually be credited as soon as you create your account.
Free spins on sign up tend to be awarded on some of the casino’s most popular games, for example Starburst or Book of Dead. Keep in mind that 100 free spins on sign up bonuses are rare and they generally come with T&Cs like wagering requirements.

100 Free Spins Bonus Codes
100 free spins bonus codes are sometimes required to get your offer. This is usually the case if an online casino has multiple welcome bonuses, for example one for sports and one for casino. Depending on the site, you might be asked to enter the code right at the beginning as part of the sign up process, or you might simply need to type it in when making your first deposit. 100 free spins bonus codes are easy to find, both here at Bookies.com and on the individual casino websites.
Deposit 10 Get 100 Free Spins
We’ve mentioned deposit bonuses already, and you’ll be pleased to find out that most casinos only require a small deposit to claim your 100 free spins offer. The most common deposit amount for a free spins promo is €10, but keep in mind that if it’s a tiered offer, you might need to deposit slightly more to get the highest possible number of bonus spins. You’ll be able to use a deposit method of your choice at a €10 deposit casino as long as it’s included in the promo.
Best Phone Casino 100 Free Spins Slots
Whether you’re claiming a phone casino 100 free spins offer, or a similar promo on desktop, the spins will usually be restricted to use on a certain game or games. We’ve rounded up some of our favourite free spins games, which most casinos offer.
100 Free Spins Starburst
If you can choose a game on which to use your 100 free spins, Starburst is one of the best options. Those already familiar with online casino gambling have probably already played this NetEnt classic before and know exactly what makes it so popular.
Starburst is extremely simple so if you’re just starting out with online slots, it’s a great choice. The game is set in space and you’ll be on the lookout for brightly coloured gem symbols to trigger wins. Starburst uses a “win both ways” mechanism, so symbols pay out both left-to-right and right-to-left, plus there are wilds and respins to keep the gameplay interesting. Starburst has a low volatility, which means that wins tend to be small but more frequent.
100 Free Spins Book Of Dead
Join adventurer Rich Wilde on his journey through the tombs and temples of ancient Egypt. The game is played on a simple grid of five reels and three rows, and you might get lucky enough to experience some of the exciting special features like expanding symbols and free spins. Look out for symbols such as ancient gods and gold-adorned icons for your chance to land a win.
Book of Dead is equal parts simple and exciting, making it a great choice for your 100 free spins. You might just get lucky and win up to 5,000x your stake. Winlandia is one of our top online casinos that offers free spins on Book of Dead, but it’s definitely not the only one.

100 Free Spins Plentiful Treasure
This Asian-themed slot game is all about luck and riches, and it even comes with four progressive jackpot prizes. The game is played on a simple grid of five reels and three rows and there are 243 ways for you to win. Simply land enough of the same symbols on adjacent reels from left-to-right to trigger a win.
If you land enough of the scatter symbols, you’ll get eight free spins where only high-paying symbols appear. There’s also a special Gold Coins feature, and this is where you can stand a chance to win a jackpot prize which usually sits in the mid-four figures.
100 Free Spins Big Bass Bonanza
Big Bass Bonanza is part of a series of popular online casino games that focuses on a fisherman character as he tries to land a big catch. The game is set underwater and features icons like a fishing rod, a tackle box and a dragonfly. Look out for the fish symbols which take on monetary values of up to 2,000x your stake which can be won during the free spins round. The game has relatively high volatility and the Return to Player percentage is above average at 96.71%, so you theoretically have a good chance of winning long-term.
Lots of top Irish online casinos like Winlandia offer 100 free spins on Big Bass Bonanza as part of the sign up offer. If you enjoy your 100 free spins on Big Bass Bonanza, you can always use online casino real money to play the rest of the games in the series.
How to Find 100 Free Spins No Deposit Casino Sites
Online casino fans in Ireland have tons of options to choose from and things are extra exciting because new gambling sites launch all the time. Not all new online casinos have 100 free spins as part of their welcome offer, but we’ll always find the ones that do and then list them here at Bookies.com.
Before we do that, we make sure that both the casino site and the 100 free spins offer meets our standards so you don’t have to spend all of your time searching for new casino promos. All you need to do is bookmark this page and come back regularly to see what’s new. We’ll also let you know if any existing online casinos add new free spins offers or update their promos to include them.
Because we know that 100 free spins slots no deposit offers are difficult to come by, we’ll also make sure we list the best deposit bonuses and other free spins promotions so you can find one that works for you.
What Makes A Good 100 Free Spins Bonus
Not all 100 free spins no deposit casino offers are created equal! In fact, there are a whole lot of factors that go into making a great bonus.
The first thing to check is the size of the offer. Of course, 100 free spins is ideal, but at the likes of 5 euro deposit casinos you might have to settle for smaller offers like 20 or 50 free spins. You might get really lucky and find a casino site where you’ll get 100 free spins on each of your first two or even three deposits.
Wagering requirements are almost as important as the size of the offer, so it’s key that you check those before you claim a 100 free spins bonus. In our opinion, wagering requirements of below 35x is pretty good, but ideally you should look out for promos that come with no wagering whatsoever - meaning the money is yours to withdraw as you please.
Next, you’ll want to look at the minimum deposit amount. For example, an offer where you deposit €10 get 100 free spins is much better than a promo that requires a deposit of €50 or €100 to get the spins.
What’s the main thing you want to do with your 100 no deposit free spins? Win real money, of course! So it’s important that the maximum win limit is generous. At least €100 is ideal, just in case you get into the bonus round.
Promo Code: BOOKIES2500
It should also go without saying that a 100 free spins offer is nothing without great games. Look out for some of the titles we’ve mentioned, for example Starburst or Big Bass Bonanza. The best free spins offers are valid on an extensive range of games, allowing you to choose.
Although a generous 100 free spins promo is a good indication of the quality of an online casino, it’s not necessarily a guarantee. Certain sites are quite simply better than others, so our casino reviews consider a lot more than just the welcome bonus.
No matter how good the 100 free spins offer is, we’ll never recommend an online casino to you unless it’s fully licensed and regulated. Licensed casino sites use secure payment methods and have strict data protection policies, and if you’re lucky enough to land a win then you’ll definitely be paid out.
We’ve mentioned how important the game selection for the 100 free spins offer is, but above and beyond that, games are one of the main things that make for a great online casino experience. We expect to see a range of at least 1,000 different online slots Ireland residents can use including jackpots, Megaways games, and new releases, plus great online casinos also offer live casino games, virtual table games, bingo, and lots more.
We also look at what people might consider quality-of-life factors, for example the desktop and mobile experience (bonus points if there’s a downloadable Irish casino app available), and the customer support options (live chat is a necessity).
While 100 free spins is a great promo for brand new players, we also want to make sure that regulars are rewarded. Consistent offers of reloads, cashback and free spins are positives, with a structured loyalty program also good to see.
How To Claim 100 Free Spins No Deposit Win Real Money Offers
Most online casinos make it super easy to claim your 100 free spins. If you feel like you need to jump through any hoops or that the process is extra complicated, you should see that as a red flag.
The easiest way to claim your 100 free spins offer is to start off here at Bookies.com. Once you’ve had a good look at all of our top bonuses, you can choose the one that works best for you and click on one of our special links to head off to the casino site.
The next step is to create your account. This is a very simple process at Irish online casinos, and you’ll need to provide some personal details like your email address, name, date of birth, and address. You probably won’t need to verify your account at this point, but you’ll be asked to provide your ID and proof of address before you can withdraw. This is for your own protection so you should see it as a positive.

You might be asked if you have any 100 free spins bonus codes during the sign up process. These codes are on this page if they're required, or sometimes you can find them in the promotions page on the casino site.
If you’re claiming a 100 free spins no deposit required offer, you might need to opt in to the promo when you log in for the first time and then the spins will drop into your account immediately. The only thing left to do is open up the valid game and start spinning to see if you get lucky.
Online Casino 100 Free Spins Terms & Conditions
Casino bonus 100 free spins offers come with terms and conditions - that’s a certainty. The best thing you can do is to make sure you’re aware of these T&Cs so that you can ensure you stick to them and get the most out of your promo. We’ll list the main ones for you on this page, but the full bonus terms are available on the safe online casino site.
The first step is to check that your preferred payment method is valid for the bonus. In some cases, you might not be able to claim free spins using Skrill or Neteller, but bank cards are almost always a viable option. You might even be able to use cryptocurrencies, like Bitcoin or Litecoin.
Next, check the wagering requirements. This will let you know how many times you’ll need to play through bonus winnings from the free spins, before you can withdraw in real cash. The lower the wagering requirements, the better.
Some casino sites restrict the amount of money you can win from your 100 free spins promo, for example you might only be able to withdraw €100 or €200. You’ll forfeit the additional money or bonus cash if you win more than that, so it’s a good idea to manage your expectations.
It’s also important to check if the 100 free spins promo comes with any time limits. Most sites require you play through your spins with seven days. You might also have a limited time to meet the wagering requirements, and if you don’t do so, you’ll lose the spins or your winnings. Some casinos only give you a day to use your 100 free spins, which can be a bit tight.
100 Free Spins Sign Up Offers Pros & Cons
How can there possibly be any cons to 100 free spins promos? Unfortunately, there are sometimes a few downsides to these offers which we’ve rounded up for you here.
| Pros | Cons |
| Great way to try different games | May come with high wagering requirements |
| You may be able to claim without depositing | Usually limited to certain games only |
| Chance to win real money | Free spins value tends to be low |
| No need to spend your own funds | |
| Easy to claim |
Are 100 Free Spins No Deposit Bonuses Legal In Ireland?
100 free spins no deposit bonus casino sites are legal in Ireland, with a few caveats. Overall, Ireland is very gambling-friendly, and you just need to be aged 18 or over to sign up at a site of your choice and gamble for real money.
Promo Code: BOOKIES2500
The most important being that they need to be offered by an online casino that holds a valid license. The Gambling Regulatory Authority of Ireland (GRAI) was only established in 2025 and licensing will be on a phased basis, so for now the best thing to do is choose a gambling site that holds a license from a reputable body like the Malta Gaming Authority. These sites have been tested for things like data security, payment reliability, and game fairness, so you don’t need to be concerned about your safety at all.
Another thing to keep in mind is that if an offer sounds too good to be true, it probably is. For example, if you find a site offering a “deposit €1 get 100 free spins” bonus, with no wagering requirements, and win limits in the thousands, the casino probably isn’t legit. Check the licensing details in the footer of the site, or better yet, only play at sites that hold the Bookies.com stamp of approval.
