If we haven't already made this apparent, slots are a big part of casinos online. In most cases, they make up the largest portion of games lobbies. It comes as no surprise that there are plenty of free spins bonuses out there. Whilst it may be tempting to claim the first one you come by, we suggest you do your research first. There's often more to things than meets the eye! Luckily, we have done the hard part for you and come up with a list of the best free spins bonuses the market has to offer. We even have the casino reviews to prove it!

Maybe you're a new customer looking to kickstart your casino experience with a welcome bonus? Or perhaps you're an existing user needing that little extra boost to help you win real money? We've got you covered with the gambling sites listed above. 

Types of Online Slot Free Spins

Remember what we said about spins not necessarily being 'free'? This brings us to our next section on the various bonus types out there. Bonus spins may be the same in nature, but varying terms has led to players being able to separate them into different categories.

No Deposit Free Spins

Sometimes referred to sign-up spins, this is the closest you are going to get to something 'free'. As the name implies, no deposit free spins are usually made available to new players. What's the catch, you may ask? Well in most cases, the only requirement you'll need to meet is registering with the actual casino. In some cases, you'll need to use codes by contacting customer support or inputting the promo code during sign-up. It all comes down to specific bonus terms but more on that later. What's important to understand is that if a casino promises no deposit free spins, then players can rest assured that they'll receive them.

Needless to say, no deposit free spins after often highly coveted, when compared to other promotions. Whilst most come in the form of a welcome bonus or as part of a welcome package, some casinos will offer some to existing players too. This said, as time goes by, gambling regulations have tightened. The result is that the no deposit strain of spins have become like gold dust. They are still available but let's just say that if you happen to come across one then consider it your lucky day!

Bonus Spins - Deposit Free Spins

There's a reason that UK players refer to them as bonus spins and we are about to explain this in our next category. Unlike the no deposit kind, players will need to meet minimum deposit requirements in order to be eligible for bonus spins. For casinos in the UK, using the term 'free' here just sounds misleading and we tend to agree!

Whilst no deposit free spins may sound like a better deal on paper, we'll remind you of what we said about the importance of reading the fine print. Free spins or not, deposit bonuses may mean that you need to meet minimum deposit requirements however they tend to come with more generous bonus terms. In addition to this, when it comes to deposit bonuses, in most cases, the spins are only half of the story for new players. Welcome bonuses tend to be a combination of spins as well as a match deposit bonus. A 'best of both worlds' situation for any type of casino player!

No Wager Free Spins

If you play slot games regularly at casinos online, then you are bound to have heard of the phrase 'wagering requirements'. Deposit bonus or not, most casino promotions require players to turn-over the bonus amounts prior to being able to withdraw winnings. Whilst the true is same for most free spins bonuses, some casinos have tried to break away from traditions and set themselves apart. We have seen a new strain of what is referred to as no wager spins and in some cases even wager-free casinos.

They seem like the perfect situation but of course, there are a few requirements or rather restrictions. In most cases, wager-free spins are offered on less popular slot games. Moreover, jackpot slot games tend to be ruled out completely. Let's just say you won't find many no wager spins on a NetEnt classic like Starburst. If you do happen to come across any, then you'll also need to keep in mind other restrictions like maximum bonus conversion. In the long run, this will all have an effect on the amount of cash you can potentially withdraw. Which brings us to our next section. 

Free Spins Bonus Terms

Now that you know your way around free spins and the various bonus types out there, we'll move on to the important information. One thing you need to understand with casinos is that a bonus is only as good as the promotion's terms and conditions. Imagine snapping up a no deposit free spins bonus and winning only to find out that it comes with a wagering requirement of 100 times your winnings! Not uncommon at casino sites and definitely something you need to be aware of. 

Luckily for you, there is no fine print with us! If you have read any of our casino reviews, then you already know this though. For those new players out there, we'll take you through bonus terms that apply to free spins and what to look out for.

Wagering Requirements Explained

Wagering, play-through rates, turnover amounts; however, you refer to them, they are part and parcel of most casino bonuses. We have already spoken about the wager-free strain but as mentioned previously these are few and far between. As for the casino free spins bonuses that do fall under the general trend, wagering requirements don't necessarily need to be feared. Players just need to understand how to pick up the ones with fair terms. These are your cash cows!

Here is where we need to differentiate once again between deposit bonus spins and the no deposit type. Wagering for the latter type can only be imposed on winnings for obvious reasons. This, combined with the fact that players are not obliged to make a deposit means that in most cases, play-through rates are higher. As for deposit bonus spins, we usually suggest sticking to those which limit wagering to the bonus amounts only. Some casinos may provide a lower figure but also bring deposit amounts into the picture. Let's just say that we recommend doing the maths first before biting off more than you can chew!

• Optimal Wagering Requirement for Sign-up Free Spins: Anything below 100x Bonus Amount
• Optimal Wagering Requirement for Deposit Bonus Spins: between 30 - 50x Bonus Amount

Max Cash Out

Fair wagering requirements doesn't mean that you should suddenly commit to a free spins deal. New players in particular beware! Maximum cash out rates can end up being just as detrimental for those looking to win real money. In layman's terms, this simply means the max bonus amount available to withdraw or rather the max bonus conversion. The good news is that those with no maximum cashouts do exist for both new players and existing customers. They are however much harder to come by and in most cases, customers will need to make a deposit.

• Optimal Max Cash Out for Free Spins: No Limits

Max Bonus Bet

Another common term which deserves a mention is maximum bonus bet. The good news about this particular conditions is that most online casinos stick to the general standards. Put simply, this refers to the limit casinos set on bet values per free spin. Whilst some casinos have opted to include this value as a percentage of the bonus amount, most have stuck to the usual fixed amount.

• Optimal Max Bonus Bet: €/£/$5

Qualifying Slot Games

Although free spins are limited to slots, which rules out other games types, game restrictions do still apply. In most cases, it comes down to RTP values and volatility of particular slot games. Jackpots for instances, tend not to contribute to wagering requirements in a lot of online casinos. In some cases, slots from particular software providers such as NetEnt and NYX can sometimes contribute less too. This all depends on the casino though which is why we always suggest checking back to the full terms. It's a long list but not something to be taken lightly.

One thing to point out is that in some cases, free spins bonuses apply to a particular slot game.  Some titles are particularly renowned for offering bonus spins and this usually comes down to the software provider. We'll look into this in more detail in the section that follows. If you are faced with a choice then we suggest sticking to top game providers.

• Slot Games Available: stick to casino slots by NetEnt, Microgaming and Play'n Go where applicable

Expiration Period

Free spins bonuses are a great boost to both new players and existing customers but they don't last a lifetime. Far from it actually, as most can last anywhere between 1 and 3 days. You won't find many free spins bonuses that go beyond 7 days that's for sure. At this stage, it's also worth mentioning that most casinos also set an expiry period on the completion of wagering requirements. This value is actually more important than the first. You'll need to weigh it up against the actual wager to see whether things are viable. Go beyond any of the limits and your withdrawable bonus funds are forfeited. 

• Optimal Expiration Time of Free Spins Bonus: 3 days+
• Optimal Time Limit for Completion of Wagering Requirements: 5 days+

Deposit Methods

Slots or any other casino game player, if you're a regular customer then this next section won't be news for you. Casinos also set limits on deposit methods eligible for free spins as well as any other casino promotion. The majority have a zero-tolerance policy towards the use of e-wallets like Skrill and Neteller when claiming deposit offers. The same usually goes for PayPal deposits at UK casinos. The good news is that no limits are set on withdrawals. So if you hit a win on one of the reels and are looking to cash in your bonus funds, you'll be able to use any payment method. Just make sure that it's available in your country.

The reasons behind this is to prevent bonus abuse due to e-wallets allowing new players to open multiple accounts. One welcome bonus per household, remember this!

Popular Free Spin Slots

Deposit bonus or not, if you're looking to play slots, then you'll be pleased to know that certain ones have a bit of a history with free spins. Play any of the titles below and let's just say that you won't need to keep your eyes peeled in order to pick up a free spins bonus along the way.

Starburst

A NetEnt classic and particularly popular with new players and welcome bonus offers. Pick out any ten casinos are we can almost guarantee that at least one will have a deposit bonus eligible on this particular slot. There are however some country restrictions that you'll need to be aware of. Canada, for instance, was ineligible for a while.

Book of Dead

With the exit of Novomatic and their world-renowned slot, Book of Ra, Play'n Go took the opportunity to launch their very own ancient Egyptian slot machine online. Not even they could have imagined the success that was in store for them. Another slot with 5 reels and 10 paylines, this also tends to be a favourite with deposit bonuses at online casinos.

Rainbow Riches

Barcrest may not be as big as the likes of NetEnt, but they still know their way around online casinos. The RTP of this slot is also slightly lower than the previous two. Perhaps the biggest reason for the abundance of welcome bonuses offering players a spin of this particular game is in fact brand awareness. Pray that the luck of the Irish is on your side and you could be cashing in bonus funds for real money in no time.

Jammin Jars

Another slot by a less renowned game provider, this next one comes with 8 reels. More reels also means more opportunities to win which is why the RTP is slightly higher than the other games mentioned. Push Gaming may not be the biggest name in online casino software but they do look to keep players happy. There are several deposit bonuses but also a few top casinos that offer no deposit free spins on this game too.

Wolf Gold

This is a jackpot slot, which as you know by now, are often ineligible to complete wagering on. The Pragmatic Play progressive slot is one of the few exceptions which casinos sometimes offer free spins on. Of course, the number of offers are scarce and in most cases come in the form of a deposit bonus. Moreover, because this is a good opportunity to win real money, strict terms usually apply. If you happen to come across an offer on this game, spin with caution, but definitely not one to be missed!

Popular Free Spins Slots by RTP

NetEnt tends to be one of the more common providers to offer free spins in fact. Below is a table of the more popular titles associated with this type of casino bonus as well as their respective RTP value.

What we like to refer to as the best of both worlds. Many online casinos nowadays are extending their welcome bonus to include a mix of different offers. Once again, they come in a few different shapes and sizes.

Deposit Bonus Money & Bonus Spins

We're going to put ourselves on the line here and say that this tends to be the most common types of welcome bonuses available online. Casinos look to combine free spins with a match deposit bonus. In some cases, it is actually extended across several deposits. The result is often a hefty welcome offer or at least that's how things may look. Always look out for terms that apply to truly ensure that you can withdraw any cash won.
