This is where our writers and editors step in to put our findings into a detailed, well written casino review. But enough about us now, let’s step into the exciting world of free spins!

What are Free Spins?

As the name suggests, free spins let you spin the reels of a slot machine for a chance to win, but without wagering your own money. As everybody loves free stuff combined with chances to win, many online casinos in the UK use free spins as a promotion tool for attracting new players and retaining existing ones. With the most sought-after promotion being no deposit free spins.

A number of free spins will be given on their own or as part of a promotional package with additional rewards (e.g. a money bonus). Usually free spins are limited to certain slot machines and have a fixed bet amount, whereas winnings are subject to wagering requirements and other restrictions before they can be withdrawn.

Whether you are looking to try a new casino, discover an exciting slot game or just try your luck – free spins are a great way to have fun and enjoy the best slot machines with chances to win prizes. And as their name suggests: they are free!

Register today to one of our recommended casinos and enjoy free spins with no deposit!

Free Spins Variances in the UK

If you are a player in the UK you can still enjoy all the great benefits and chances to win that come with free spins, but due to advertising restrictions enforced by the UKGC you will need to first register to the casino and claim what’s now called a sign-up bonus.

To enjoy this extremely popular reward that still lets you claim no deposit free spins, follow these quick and easy steps:

  1. Select one of our recommended casinos that offers a sign up bonus.
  2. Sign up to the casino following a quick and easy registration process.
  3. Claim your bonus by entering a bonus code provided or by meeting a minimum deposit requirement.
  4. Choose a from the great slot games available with free spins.
  5. Enjoy spinning with chances to win money!

Some free spins casinos will automatically credit the bonus to your account once you completed registration so you won’t need to add a bonus code in this case. It is also recommended to read the casino’s terms and conditions to fully understand the wagering requirements and other bonus rules and you can find these in our online casino reviews.

Wagering Requirements for Free Spin Offers

As the name suggests, no deposit free spins give you a chance to play on the best real-money slots without making a deposit or risking your own money. And when played on a real-money slot game, free spins can land the reels on a winning combination that entitles you to prizes. There’s absolutely no need to worry that your free spin winnings will disappear because the casino will always credit your account balance with the amount you won. However there are a few things you need to know before cashing out your winnings.

The money credited to your casino account is bonus money, which you will need to play through several times before you can redeem it into cash and make a withdrawal. The times you will need to play through (wager) your bonus money before turning it to cash is commonly known as wagering requirements and these are stated clearly in the free spins terms and conditions.

So if for example the casino offer terms state that free spins no-deposit offers have a 35x wagering requirement, it means you will need to play through your free spin winnings 35 times before being able to make a withdrawal. Most free spin casinos also require that you make a deposit before being able to withdraw winnings and some have additional limits and restrictions. Therefore we always recommend that you check the free spins offer terms and conditions to fully understand requirements.

Armed with all the important guidelines to help you understand the ins and outs of free spins, you should now take a look at the list of the UK’s best free spins that our team put together. Remember that we only recommend the best online casinos and we bring you the most generous bonuses available in the market.

The Different Free Spin Bonuses Available in the UK

Some of the best casinos in the UK will give you free spins just for signing up. These no deposit free spins are a great way to get a taste of the casino and try new slot machines, but they usually include just a few free spins that you will play through quickly. If you are looking for an even more exciting casino experience with generous rewards and chances to win bigger prizes, why not check the great deposit bonuses we feature on our site?

We put together a quick list of slot sites offering free spins, so hopefully so you can spend less time looking for the best offer and more time spinning the reels:

Free Spin No Deposit Slot Games

Casinos give no deposit free spins to attract new players to sign up but they also use free spins to offer players the opportunity to try popular slots. Most free spins are tied to specific slot games that are offered by the casino. Sometimes these are brand new online slots that the casino is looking to promote. In other instances the free spins are connected to classic slots that already have a wide following.

The newest slots that feature with free spin promotions constantly change throughout the year, while free spins on classic slots tend to stick around so they can always be found. This variety allows players of all interests and levels of experience different games and benefit from the free spins.

NetEnt slots that feature in many free spin no-deposit promotions include Gonzo’s Quest and Twin Spin which are extremely popular amongst real-money players as well. Another classic title that is offered with free spins is adventure-themed Rich Wilde and the Book of Dead by Play’n Go.

You can try it with a 50-free spin deposit offer. One more favourite online slot machine that is commonly featured with free spins is Immortal Romance by Microgaming. This exciting, sleek video slot follows the story of dark desires and vampire love. It is one of the innovative slots that features 243 ways to win, so your Immortal Romance free spins can definitely generate some exciting wins!

Still, keep in mind that some popular slots like Microgaming’s Mega Moolah and other jackpot games are almost never featured in free spin offers. This is because these are progressive jackpot slots, and free spins do not count towards progressive prize pools.

So promoting a jackpot slot with free spins would be somewhat counter-productive. Other slots that won’t usually offer free spins are branded slots like Anchorman which don’t feature free spins because of royalty constraints that require to pay for any usage.

However these, and many other great slots are still included in other tempting bonuses and promotions, and are definitely worth playing!

Free Spins for Existing Players

Once you have signed up to the casino, made a deposit, played and probably won some bonus funds, you are considered a regular casino patron.

Although no longer eligible for a welcome bonus targeted at a new player, you will be glad to know that there are many attractive free spin offers that existing casino players can claim and enjoy. But note that there are very few no-deposit free spin offers available to regular casino players, so most of the free spins will be awarded as a casino bonus tied with a payment transaction.

In most of these promotions for a returning UK player such as reload deposits, free spins are given as an extra perk bundled up with a handsome money bonus.

There are some exceptions still, such as players being given no deposit free spins in a special casino tournament or casino event. When it comes to returning players, online casinos know how to reward loyalty so we are sure you won’t be disappointed. To learn more, read our detailed reviews that always cover loyalty programs and promotions for returning players.

Free Spins On Starburst

Probably due to being one of the most revered slot games in the world, Starburst is consistently connected to free spin no deposit, and free spin deposit offers alike.

One of the reasons this NetEnt slot is loved is a design boasting immersive neon graphics and captivating audio. Many players around the world also love playing Starburst because of its high RTP (Return to Player) which is the percentage of payback to players.

While online slots average an RTP of 95%, Starburst boasts a payback of 96.6%! In addition, Starburst has a high frequency rate (also known by players as ‘hit rate’) which is the frequency of winning spins. Many top ranking NetEnt casino sites in the UK feature free spins bonus on Starburst, with some even offering hundreds of free spins on this exciting and popular game.

Free Spins On Mobile


Every leading mobile casino offers the most popular slot games along with free bonus promotions on mobile devices. Beside their main desktop client, all our featured casinos offer their games for instant access through a browser on Android, iOS and even Windows mobile devices. Many casinos take the mobile experience further by offering native apps that can be download and installed iOS and Android phones and tablets.

As the leading slot games are based on advanced HTML5 technology, they are optimized for mobile devices and provide mobile users with superior design, graphics resolution and sound. This immersive experience also includes free spins that became an essential part of mobile gambling. Casinos quickly realised the importance of free spins on mobile and many now offer free spins that are exclusive to mobile players. So if you are a casino player that loves slots and has a mobile device, you can play your free spins anywhere, anytime!

Free Spins as a Slot Game Feature

In addition to free spins given by the casino as part of a promotion, there is another type of free spins which is embedded in the game itself. Many slot machines have a programmed feature that triggers free spins during the game. These free-spin games bonus rounds are randomly triggered by a combination of winning symbols shown on the reels (e.g. a combination of Scatter, Bonus or Free Spins symbols).

Free spins are triggered with a spectacular display of on-screen animations and sounds that add to the excitement. But beyond the great fun and entertainment, there’s always the possibility of bonus spins landing a winning combination in the reels. This anticipation grows even further as the free spins themselves can trigger more bonuses in addition to wins.

The requirements for getting no deposit bonus free spins in the UK include signing up to an online casino by going through a secure, quick and easy registration process that includes age verification.

Of course! The leading UK casinos offer no deposit free spins on their mobile-browser clients and mobile apps. Some also have mobile-exclusive free spins offers.

Most free spins for returning players will require a deposit, but they are usually given in addition to generous money bonuses.

A wagering requirement is the amount of times required to play through bonuses and free spins until they can be redeemed and withdrawn as cash.

Yes you can! Free spins have the same chance of winning as any other spin, but withdrawals are subject to casino terms and conditions.

You certainly can! Many VIP programs and casino loyalty schemes often give free spins as part of their reward program.

There is no particular type of a free spin that is the best because free spins have the same probability of winning as real money spins. So every free spin has great potential!

Some of the most popular slots featured on free spin offers include Starburst and Gonzo’s Quest. Still, keep in mind that free spins are offered on many other great games.

As free spins do not count towards the player’s contribution to the jackpot prize pool, they are almost never offered on progressive jackpot slots.

You will receive multiple no deposit free spins when you sign up. But as most casinos restrict their no-deposit free spin offer to new customers, you can probably get this offer only once in a given casino. For more information, check the casino’s promotions terms and conditions.

Yes you can! But keep in mind that cashing out these winnings will be subject to wagering requirements and more bonus rules and restrictions. Check the casino’s terms and conditions for more information.

Occasionally new casinos will offer better no deposit free spins in order to attract players. However more established casinos tend to have bigger advertising budgets which are sometimes invested in no deposit free spins that can be just as attractive!

Some casinos limit free spins to certain payment methods. But as no deposit free spins are usually given before any payment is made, it shouldn’t have an effect on your eligibility.

It is unlikely. No deposit free spins are generally given for slot games, whereas live casino games are usually live-dealer table games and not slots.
