Free spins are sometimes called free games, extra spins or bonus spins, but still mean you get to spin some of the biggest slot games out there using the casino’s money.


There are plenty of casino sites that serve up free spins bonuses to new players and at some brands, there are literally hundreds up for grabs when you sign up and deposit for the first time.

What is a free spins bonus?

Free spins are what they say they are – a set number of spins on a slot or slots that you play with the casino’s cash.

Some casinos will just offer free spins as the welcome bonus, while others will combine it with a deposit match bonus. Others will add cashback into the package, too.

Use our tools to help find the online casinos that offer the free spins bonuses you’re looking for.

Different types of free spins bonuses

There are several types of free spins bonuses available at UK casino sites, so it’s important to understand what each provides so you can find the brands that offer the right bonus for you. These are the most common.

Free spins with card registration - Sign up, provide your card details and receive free spins without making a deposit.

Free spins with low wagering requirement - Sign up, deposit, receive free spins and complete a low wagering requirement of no more than 30x.

Free spins on deposit - Sign up, make a deposit and receive free spins. Simple as.

No deposit free spins - Get free spins without having to provide card details or make a deposit of your own.

Free spins with no wagering requirement - Sign up, deposit, receive free spins and withdraw your winnings without completing a wagering requirement.

Why claim a free spins bonus

Who wouldn’t want to spin the reels on blockbuster slots with the casino’s money? These are some of the other upsides to claiming a free spins bonus.

Use the free games to enjoy spins on popular slots such as Starburst and Book of Dead without having to use your own cash.

Casinos can be incredibly generous with their free spins, with some offering more than 200 when you sign up and make a deposit for the first time.

Most online casinos include free spins in their welcome bonus, so you’ll have plenty of brands to choose from.

Win real money from a free spins bonus – subject to Terms and Conditions, of course.

How to calculate the value of an extra spins bonus

It’s all well and good being offered 120 free spins, but what’s the actual value of the bonus? Working this out is pretty straightforward.

Simply multiply the number of free spins you’re being given by the per-spin value – you’ll find this in the bonus T&Cs.

Here’s an example:

The casino offers new players 100 free spins when they sign up and deposit for the first time. The per-spin value is £0.50.

This makes the total value of the free spins bonus £50 – 100 spins x £0.50 per spin = £50.

Of course, you need to factor in other T&Cs such as wagering requirements to work out the true value of the bonus – more on this later.

How to claim a free spins bonus

Claiming an extra spins bonus couldn’t be easier – just follow these steps.

  1. Browse and compare all free spins bonus casinos using our tools and filters.
  2. Once you’ve found the casino and bonus you’re looking for, check the bonus T&Cs.
  3. If you’re happy with the T&Cs, click “Play”.
  4. Follow the casino sign-up process, accept the bonus offer and make your first deposit.
  5. Use your free games bonus to have fun at the casino.

Free spins bonuses and a few things to consider

Free spins might claim to be free, but in reality, they often aren’t. They come with T&Cs that can impact the value of the bonus you receive.

Terms and conditions are applied to all casino bonuses and are specific to each bonus. It’s important to read them and understand what they mean before claiming an offer.

This is because the T&Cs can reduce the value of the bonus when you factor in things like win limits and wagering requirements.

That’s not to say extra spins don’t add value to your play, but being aware of the T&Cs means you know exactly what the bonus ultimately delivers.

Free spins bonus T&Cs to be aware of

T&Cs can be quite lengthy, so we’ve broken out the key terms to be aware of, what they actually mean and the impact they can have on the bonus offer.

Maximum bet - The maximum amount you can bet on a single spin when using free spins.

Cap on free spins winnings - The maximum amount you can withdraw from the free spins.

Payment restrictions - Free spins might not be available when depositing with some payment methods, usually digital wallets like Skrill and Neteller.

Wagering requirements - How much you need to playthrough before you can withdraw your bonus or winnings as cash.

Limited game selection - The slots that you can play using your free spins - this is often just one game.

Bonus expiry - The amount of time you have to use the extra spins before the bonus expires.

Minimum deposit to unlock free spins - Most free spins bonuses have a minimum deposit to unlock the offer, usually between £10 and £20.

Casino bonus wagering requirements explained

The wagering requirement is the number of times you have to wager the bonus amount or your winnings before you can withdraw the bonus amount or your winnings as cash.

Wagering requirements vary significantly. Low wagering casinos will impose playthrough requirements of between 10x and 30x, but they can be as high as 65x at some brands.

There are a small number of now wagering casinos that impose no playthrough requirements whatsoever – although the value of the free spins bonus offered is usually much less, it’s your money to play with and withdraw as and when you want.

Working out the wagering requirement on a free spins bonus is easy – the wagering requirement is usually applied to your free games winnings.

  • Calculate your winnings from the extra spins bonus
    Multiply this by the wagering requirement

This will give you the total amount you have to wager before you can unlock your winnings as cash.

How to calculate the wagering requirement

Still not sure how it works? Here’s an example.

You’re offered a free spins bonus of 100 free games on Starburst when you deposit £20 with a wagering requirement of x40. You play the spins and win £10 in bonus cash.

Bonus: £10
Wagering requirement: x40
Amount to be wagered: £10 x 40 = £400

This doesn’t mean you have to deposit and lose £400, just that you need to cycle that value through the casino before you can unlock your winnings as cash.

There’s a growing number of free spins casinos that don’t impose wagering requirements, so you can keep what you win.

How to get the most out of a free spins bonus

The best way to make sure you get the most out of extra spins is to understand the terms and conditions attached to the bonus being offered.

You should check the bonus cap as this ultimately determines the most you can win from the free games. But it’s also important to be realistic – you get a small bonus to tempt you to try the casino for free. You’re unlikely to win big especially when the T&Cs and wagering requirements are applied.

That’s why it’s important to use free spins to have fun and try the casino before playing with your own money.

Of course, if you don’t like the idea of completing the wagering requirement, look for no wagering or low wagering casinos that also offer bonus spins – our tools can help you do this.

An important word on responsible gambling

Online casino is fun and enjoyed by millions of people across the UK. But it’s important that it does stay fun and that you remain in control of your play. Because we only partner with UK-licenced online casinos, each of the brands listed on Comparasino offers the tools you need to do this.


But some of these tools might be unfamiliar and it can also be tough to determine if you, or a family member or friend, could potentially have a gambling problem. That’s why we’ve created a Safe Gaming Hub where you can find information about all the responsible gambling tools offered at online casinos, how they work and which ones might be best for you.


It also contains insights into some of the early signs of problem play to be aware of in yourself and others as well as direct access to charities and organisations that support those with problem gambling habits.
