What Are Free Spins?

Free spins are a type of casino bonuses linked to video slots. A free spin is a complimentary round worth a real cash bet. If that round ends with a winning sequence on the reels, you will win real money. 

Casinos use different types of free spins as a promotional feature, to attract new players and retain existing customers. Unlike a cash bonus, free spins can only be used to play video slots. 

Free Spins vs. Free Play

“Free play” is a feature offered by many UK online casinos to registered players. You can “test” a slot game in the catalogue using virtual coins instead of Pounds or Euros. This is mode is also called “demo play” or “fun play.”

Fun play/free play is a decent option to try out an unfamiliar slot without spending any money. But the downside is that you don’t get a chance to win any money. With free spin bonuses, this is not the case – winning rounds add cash to your casino balance which can be withdrawn. 

Free Spins Vs Bonus Spins

Many modern 5-reel video slots come with attractive gameplay features and bonus triggers. Scatter and Wild symbols on the reel can trigger special effects that add variety and excitement to the gaming experience. Some of them can also trigger bonus free spins.

Such bonus spins are random prizes you get inside a particular video slot game. On the other hand, a free spin bonus is awarded to you by a casino, in exchange for performing desirable tasks like joining the casino and adding funds to the casino.

Free Spins – How They Work

Free spins are pretty simple. You get “x” number of spins on a specific slot game. Log in to your casino account and open that particular game – you will see the available free spins on the game screen. 

Spin the reels until you use up all the free spins – if you win any quids, they will be added to your casino balance. In most cases, this money is locked until you complete the wagering requirement. Once you fulfill the wagering, you can withdraw the funds to your bank/card.

How UK Casinos Award Free Spins

Casinos have a wide range of promotional offers, aimed at different categories of players.

You will often receive a free spin bonus from the casino in the following ways:

  1. Welcome Bonus – you get free spins as part of your welcome package when you sign up for the first time at a casino. These new player free spins can be further divided into no deposit free spins and deposit free spins (more on that later).
  2. Deposit Bonus – casinos offer these to encourage registered players to make cash deposits. Some offers combine a match deposit bonus with free spins. With others, you exclusively get free spins for a deposit.
  3. Loyalty Programs – Free spins are a common reward given as part of the casino loyalty programs. You can claim these offers by staying on as a paying customer at the casino for a long time.
  4. Referral Bonus – Most casinos offer a free cash chip to players who introduce the casino to their friends. But a few also offer free spins instead. If someone you referred signs up at the casino, you get those spins.
  5. Birthday/Festive/Annual Bonus – to enhance player satisfaction, casinos often provide exclusive free spin bonuses on special days like your birthday, holidays, or the anniversary of your joining the casino.

The Types of Free Spins

Based on factors like deposit and wagering requirement, you can divide free spins into three main categories:

No Deposit Free Spins

Most bonuses are awarded to players who deposit cash into their casino account. The only notable exception to this rule comes in the form of no deposit bonuses – these are awarded even before you make that initial deposit.

No deposit free spins allow you to play some of the most popular video slots in the industry without spending a single penny. These bonuses are designed to encourage people to sign up at a casino. As soon as you register an account, the free spins are credited instantly.

The upside of a no deposit free spin bonus is that it is absolutely free. If you are skint and want to play a few rounds of real cash slots, there is no better way to get it done! But the downside is that you don’t get a lot of spins – expect no deposit free spins to stay between the 10 – 100 spins range.

For example, Slots Heaven Casino offers 20 free spins no deposit on Age of Gods. Betfair Casino has a much bigger offer at 50 free spins on Daily Jackpot Games. This is Vegas Casino tops them all with a huge 130 free spins no deposit offer on Diamond Cherries.

No Deposit Free Spins

Free Spins with Deposit

While no deposit free spins are aimed at new players, deposit free spins can be claimed by all players. As a new player, you may get welcome packages that include a free spin component on top of a match deposit bonus.

And once you become a regular player at the casino, you will get to claim even more free spins with your regular deposits. One main advantage of deposit free spins is that you can claim them multiple times. This option is not available with no deposit free spins – they are one-time offers at all online casinos.

Deposit Free Spins

Zero Wager Free Spins

This is a new type of casino bonus. As the name suggests, it does not come saddled with any wagering requirements. Both no deposit free spins and regular free spins have wagering requirement in their bonus terms.

Zero wager free spins are brilliant, if you can find them – very few casinos offer this kind of bonus as it is quite risky (for the casino). No wagering means that you can instantly withdraw your winnings. To learn more about this exciting bonus, check out our page on zero wager casinos .

Free Spins UK – Are They Legal?

The UK has one of the most well regulated online gambling markets in the world. The Gambling Commission is quite strict when it comes to enforcing rules and protecting players from unscrupulous operators. 

Only free spins from UK Gambling Commission-licensed casinos can be considered legal. If you want the safest online gambling experience as a UK citizen/resident, always stick to casinos that are licensed to operate in your country. 

Here at NoDeposit.Guide, we make it a point to check all online casinos for licenses before featuring them on our page. All the free spin offers listed on our UK page come from trusted casinos that accept UK players. If you want legal, safe, and fair UK free spin bonuses, you are at the right place!

How to Claim a UK No Deposit Free Spin Bonus

All free spin bonuses require a registered account at the casino. Especially in the UK, the online gambling rules prevent casinos from offering demo spins to visitors. This is an important step to prevent children from accessing gambling games.

We will split the process of claiming a no deposit free spin bonus into two main parts:

  1. Registering an Account
  2. Claiming the Bonus

Registering an Account

Since this process is nearly identical across all casinos, we will not use specific examples.

Just follow these simple steps to create a new account at any UK casino:

  1. Visit the casino website using a PC or mobile browser.
  2. Click on Sign Up/Join Now/Register button on the welcome page.
  3. Fill the forms with details including your name, age, gender, and country.
  4. Create a unique username and password for your casino account.
  5. Provide contact details – email, mobile number, postal address.
  6. Confirm that you are over 18 and agree to the casino terms and conditions.
  7. Complete the registration process.

At this point, the casino will send an email/SMS to you to verify your identity. Open the mail or message and follow the instructions to finalize the registration process and create your new account.

Claiming the Free Spin Bonus

There are two main methods to claim a no deposit bonus.

Let’s explain using a couple of examples:

888 Casino

88 Free Spins No Deposit on Starburst – Automatic

The 888 Casino free spin bonus comes with an “Automatic” tag. This means that the free spins are automatically credited to your account, as soon as it is created using the steps we listed above. You don’t have to do anything extra to claim the free spins.

Betfair Casino

50 Free Spins on Daily Jackpots – Code CASF51

The Betfair Casino no deposit offer comes with a special code – CASF51. You have to type or copy-paste this code accurately in the space provided at the casino. In this example, you can either enter the code manually during the registration in the relevant space or click on the “Opt-In” button from the casino promotions page.
At some casinos, the claiming of a no deposit bonus code comes after the registration process. Log in and head to the cashier/promotions page of the casino to pick the no deposit free spin from the available offers to claim. In some rare instances, you have to contact customer support to activate your free spins.

Most Popular Slots with UK Free Spins

UK players are spoilt for choice as far as game variety is concerned. As of the largest, well-regulated markets in the world, the UK attracts all top casino software providers in the industry. And since the rules are so strict, only the best vendors with provably fair slots are allowed into the UK market.

Here are some of the amazing slots you can play with free spins no deposit at top UK casinos in 2021:

Vendor Game Casino No of Free Spins Bonus Code
Netent Starburst 888 88 Automatic
Playtech Age of the Gods Slots Heaven 20 Automatic
Play N Go Book of Dead NY Spins 20 Automatic
Rival Gaming Diamond Cherries This Is Vegas 130 Automatic
Betsoft Reel Royalty Mr Spin 50 Automatic

Starburst – The Most Common Free Spin Slot?

A quick scroll down the list of no deposit free spin bonuses will throw up one name on multiple occasions – Starburst. The Netent slot is a mainstay of no deposit free spin bonuses at UK casinos. And it is quite old, having launched way back in 2012.

But even after a decade, the space-themed slot continues to be a hit among players. Its simple yet elegant graphics, user-friendly mechanics, and lucrative bonus features make it a popular choice for beginners and expert players alike.

When casinos create a free spin bonus, they want to put their best face forward to impress the players. And a legendary slot like Starburst, coming from arguably the most popular slots provider out there – Netent makes the perfect option for no deposit free spins.

You can claim Starburst free spins no deposit at the following casinos:

Book of Dead – The other popular no deposit free spin slot

Developed by the provider Play N Go, Book of Dead is yet another evergreen classic among the world of video slots online. If you want a slot with a bit more action theme than Starburst, Book of Dead is ideal.

The Egypt-themed slot is part of the Rich Wilde series – with a handsome leading man in the mould of Indian Jones. Expect plenty of treasure hunting, Egyptian gods, scarab jewels and more in this 5 reel slot launched in 2014.

How to Win Real £££ With Free Spins UK

Claiming and playing with a free spin bonus is easy. And winning requires a fair bit of luck but is fun while you are at it. But winning cash with a free spin bonus is not the same as withdrawing it and getting your hands on that cash. 

The latter requires a bit of planning and preparation when you pick a free spin bonus. And it requires a good understanding of how casino bonus rules work. Naturally, you also have to take the time to read all casino bonus terms before claiming any free spins if you really want to improve your odds.

Tips to Win & Withdraw Real Money with Free Spins

  • Pick free spins that come with the lowest wagering requirements – below 30x is ideal.
  • Pick offers with the largest cashout limits – for no deposit spins, £100 is the average.
  • Claim bonuses linked to slots with high RTP – above 96% is ideal.
  • With no deposit spins, claim as many offers as possible – it is free!
  • Deposit free spins are better than no deposit spins for winning.

How Free Spin Bonus Terms Affect Your Odds of Winning

No one lines reading boring legal mumbo-jumbo written in terms and conditions. But if you are serious about winning cash with any casino bonus, you have to make an effort here. Luckily, bonus terms are quite short, easy to read, and to the point at the best UK casinos.

Here are the main terms you need to keep an eye on:

Eligible Games

Casinos only allow you to use free spins on selected slots. With no deposit free spins, this is usually limited to a single slot game. Any attempt to use free spins on ineligible slots will result in the voiding of your winnings! Also, the RTP of the slot plays a huge role in deciding your odds of winning real money.

Wagering Requirement

You should never claim a casino bonus of any sort without learning how wagering requirements work (unless it is a no-wagering bonus). This is a crucial rule that decides if and when you can withdraw your bonus winnings. To do that, you have to first place many bets using your bonus/winnings.

We have an entire page dedicated to explaining what this all-important rule is and how it works – don’t forget to check it out if you don’t know anything about wagering requirements. To learn a bit more about wagering, scroll down to find our guide to calculating a free spin bonus wagering requirements.

Max Cashout

Also called a “max win” limit, this rule dictates how much cash you can withdraw from your free spin winnings. If the cashout limit of a free spin bonus is £100 you can only withdraw the portion of your winnings equal to that amount – -the rest is voided by the casino.

Max cashout rules are important as they give you a clear idea of how much you can expect to win with a free spin bonus. While no deposit spins have a set limit like £100, with deposit spins they usually specify a multiplier – for eg, the limit will be 10x your initial deposit.

Expiry Dates

All bonuses have an expiry date. No deposit free spins expire within 24 hours at most casinos. Deposit free spins may last for a week or more. Always try to finish the bonus play and wagering within the deadline to avoid losing out on a payout!

How to Calculate the Wagering Requirement of Free Spins

Calculating the wagering requirement of free spins is easier than other casino bonuses.

Example

Let’s use a real-world example to illustrate how this is done and explain why low wagering is better:

Lady Aida Casino – 50 Free Spins on Reel Royalty – 45x wagering

The wagering multiplier in this bonus is set at a reasonably low 45x on your free spin winnings.

If you win £50 using those 50 free spins, you can find the wagering requirement target using the following formula:

Bonus Winnings (£50) X Wagering Multiplier (45x) = Wagering Requirement (£1000)

In this scenario, you have to keep placing bets with that £50 until the total cumulative value of those bets reaches £1000.

Now, that may sound like quite the task, but consider the same example with the wagering multiplier doubled to 40x:

Bonus Winnings (£50) X Wagering Multiplier (40x) = Wagering Requirement (£2000)

Your wagering target has doubled to £2000 which is considerably harder to achieve than £1000 with that 50 quid.
This is why lower wagering multipliers are always considered better for players.

How to Find the True Value of a Free Spin Bonus?

Many rookie players make the mistake of beelining to the biggest bonus in terms of free spins. As we already explained, the number of spins is not a reliable indicator of the quality of a bonus. Factors like wagering requirement and the slot game involved have a much bigger say in this matter.

To know the actual value of a free spin bonus in terms of cash, you need to know the following variables:

  • The minimum bet/coin size
  • The total number of free spins
  • The number of paylines
Example

Let’s illustrate this point with an example:

Sloty Casino – 20 Free Spins of Starburst – 40x Wagering

The 20 free spins here are eligible on the slot game Starburst from Netent.

In the case of Starburst, the minimum bet size is 0.01.
As a rule, casinos set the bet size at the lowest level permitted by a slot, unless specified to the contrary.
This is why we need to find this number from the slot involved.

Starburst has 10 paylines. And we already know that the offer gives us 20 free spins.

Combining these three variables, we can use the following simple equation to find the actual value of a free spin bonus:

Minimum Bet Size (0.01) X total paylines (10) X number of spins (20) = Total Value of Free Spins (£2)

Now imagine an offer with fewer free spins (10), and a slot with a bigger minimum bet size (0.05).

Let’s set the number of paylines at 50. Using the same formula, we get:

Minimum Bet Size (0.05) X total paylines (50) X number of spins (10) = Total Value of Free Spins (£25)

Despite having half the number of spins, the second free spin bonus has a massive advantage over the first offer.
This is why it is important not to pick a bonus just because it has 100 free spins.

What is the Expected Value of a Free Spin Bonus – How to Make a Profit?

The true value of a bonus is useful when comparing different free spin offers. But it does not tell you anything about your odds of winning. If you are set on making a profit with a free spin bonus, you need to use the Expected Value formula. It tells you how much you can expect to win using a bonus on average.

To find out if this bonus is going to land you a profit, you need the following three variables:

How much is the max cashout?

We can assume this to be £100.

What is the total wagering?

Assuming a winning amount of £50, the wagering requirement would be £50 multiplied by 50x, or £2500.

What is the house edge of the slot?

To find the house edge of a slot, you need to know its RTP. Here, Starburst has a stated RTP of 96.01%. The difference between that and 100% is 3.99%. When we convert that into a whole number (divide it by 100), we get 0.039. That is the house edge.

Example

Here is how it works with an example:

888 Casino – 88 Free Spins on Starburst – 50x wagering

Once we have the three variables, we can move ahead with the equation
to find the expected value of the 888 Casino free spin bonus:

Max Cashout £100 – (Wagering £2500x House Edge 0.039) = Expected Value £2.5.

The expected value of this bonus is positive, which is a huge deal! More often, you will find bonuses with expected value as a negative number.
This means that you have very little chance of having a positive cash balance after playing with the bonus.

Playing Free Spins on UK Mobile Casinos

Many industry experts consider mobile gaming to be the future of the online casino business. And nowhere is this more evident than in the UK. We can safely say that all UK online casinos have 100% mobile compatibility. 

The biggest brands, like 888, BetVictor, and Betfair all have dedicated apps on iOS and Android app stores. The smaller online casinos may not have the financial muscle to build and maintain secure mobile apps on two software ecosystems. 

But even those smaller sites offer full mobile gameplay compatibility using HTML5 website technology. You can access all UK online casinos on your iPhone and Android devices using your favourite mobile browser. 

With such seamless integration between mobile and desktop variants of online casinos, we see a move away from the old ways. In the past, mobile gamers were at a disadvantage, as they did not have access to all the games or bonus offers. But this is no longer the case. 

You can access the hottest free spin no deposit offers from UK casinos right on your mobile device. As long as you have a device with a modern browser like Chrome/Safari (fully updated) you are good to go.

Conclusion – No Deposit Free Spins vs Deposit Free Spins – Which to Choose?

The right answer here is – pick them both! Why? It’s simply because they serve different purposes.

Use a No Deposit Free Spin Bonus when:

  • You want to test a new casino
  • You want to try out a new/unfamiliar slot
  • You are new to online casinos
  • You are broke!
  • You want a slender chance to win money free!
  • Use a Deposit Free Spin Bonus when:

  • You find and join a trustworthy casino
  • You want more free spins
  • You want lower wagering requirements
  • You want a higher/no cap on winnings
  • You want to play more slots
  • You have money to spend!
  • As you can see from those reasons, deposit bonuses are much better if you have the cash to spare. They have lower wagering and higher cashout limits, both of which have a huge impact on your odds of winning real money with free spins.

    FAQ

    Yes, no deposit free spins may not cost you any money, but they still give you real cash bets on slots. You will always have a chance to win real money – check our tips on improving your odds to get a better chance of winning!

    Casinos use wagering requirements to prevent players from taking advantage of bonuses (bonus abuse). Without wagering, there is nothing to stop a player from claiming a bonus and withdrawing it straight away – that would in essence mean that the casino is giving away free cash! To reduce the chance of financial ruin, casinos rely on wagering requirements on all bonuses.

    No deposit free spins are technically free as you are not required to spend any money to claim them. But when it comes to making a withdrawal of the winnings, the casino bonus terms will usually dictate that you make a small cash deposit. From that perspective, even no deposit bonuses are not “free” in the true sense of the word.

    No, this is set in advance by the casino and cannot be altered by the player. However, you can look at the bonus terms and linked games of different free spin bonuses and pick one with higher bet limits. In that case, avoid slots that have a 0.01 minimum bet limit.

    You have to search for no-wagering casinos. Here at NoDeposit.Guide, we have a page dedicated to zero-wager/wager-free casinos. Since there are only a few such casinos, your options will be limited. Only the top brands have the financial power to give such generous offers.

    Any slot with a high RTP above 96% and multiple paylines is a good option for free spin bonuses if you want to increase your chance of winning money. Some popular choices include Starburst and Book of Dead.
