Guide to Free Spins UK Offers for September 2021

Now that we have listed all the top-ranking free spins casinos, it’s time to make a more detailed comparison between them to make sure you get the best free spins bonuses. In this comprehensive guide, we cover everything you need to know about online casino free spins offers in 2021.

Free spins give you a chance to play on the best real-money slots without making a deposit or risking your own money. 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 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.

Read on to learn how free spins work in the UK, which games offer free spins features, and find the online slots sites that offer the best offers in the UK for free spins.

What are Free Spins in the UK?

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 fresh players and motivating them to come back, with the most sought-after promotion being free spins.

Free Spins Alternatives: Extra Spins and Bonus Spins

UK players seeking free spins in 2021 might notice that several casinos licensed in the UK are not offering free spins anymore. Instead of free spins offers, you will see “extra spins” or “bonus spins” offers bandied around instead. However, this is in most cases a change in terminology that certain operators are implementing to be extra sure that they fall in line with the UK’s new online gambling regulations.

The truth is, they are still free spins, and calling them a different name simply helps these casinos reassure regulators that they are not luring in at-risk players with tantalizing free spins. This helps them avoid fines or getting their gambling licences suspended or even revoked. So, if you can’t find free spins at your favourite UK casino, look for these alternative terms instead.

Whether you are looking to try a new casino, discover an exciting slot game or just try your luck – free spins are a fantastic way to have fun and enjoy the best slot machines with chances to win prizes. Register today at one of our recommended casinos and enjoy free spins!

No Deposit Free Spins – Real or Myth?

Now, there are some casinos that still offer bonuses with no deposit needed, but these are becoming rarer. It’s much more likely that free spins will be part of a promotional package with other rewards (e.g., a no deposit money bonus). Usually, free spins are limited to certain slot games and have a fixed bet amount, and winnings are subject to wagering requirements and other restrictions before they can be withdrawn.

The exception to this is VIP players. If a particular player is loyal to the casino and deposits enough to be considered a high roller, their account manager might throw in some free spins with no deposit needed from time to time if the player requests it in certain cases.

We created this list to help you focus your search, but keep in mind that many of these offers include additional rewards such as generous money bonuses that are given on top of the free spins. We couldn’t include all the great offers in one list as it would have been too long, so make sure you don’t miss out on all the other fantastic free spins featured on our site and our recommended new slot sites.

Free Spins Welcome Offers 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 your free spins, follow these quick and simple 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 supplied or by meeting a minimum deposit requirement.
  4. Choose 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 have 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, read our in-depth online UK casino reviews.

Free Spins for Existing Players

Can existing players claim free spins? It’s a legitimate question. Most free spins for returning players will require a deposit, but they are usually given in addition to generous money bonuses. Our recommended UK casinos often promote a new slot with free spins to new players, but they also have free spins offers for existing players from time to time.

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 spins offers that existing casino players can claim and enjoy. But note that there are very few no-deposit free spins 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 money bonus.

There are some exceptions still, such as players being given 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. In fact, players that quality for VIP status at most casinos will enjoy free spins offers on many more games for a longer time.

To learn more, read our detailed reviews that always cover loyalty programs and promotions for returning players.

Wagering Requirements for Free Spins

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 are commonly known as wagering requirements and these are stated clearly in the terms and conditions of the free spins.

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 deposit 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 the requirements.

Armed with all the important guidelines to help you understand the ins and outs of free spins, you should now 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 free spin bonuses available on the UK market.

Types of Free Spins Offers in the UK

Some of the best casinos in the UK will give you free spins just for signing up. These free spins are a terrific 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:

We created this list to help you focus your search, but keep in mind that many of these offers include added rewards such as generous money bonuses that are given on top of the free spins. We couldn’t include all the great offers in one list as it would have been too long, so make sure you don’t miss all the other fantastic free spins featured on our site and our recommended new slot sites.

Free Spins on Slot Games

Casinos give 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 slot games that feature 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 to 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 generate some exciting wins!

Still, keep in mind that some popular slots like Microgaming’s Mega Moolah and other jackpot games are seldom 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 paying for any usage.

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

Free Spins on Starburst

Probably due to being one of the most well-known slot games in the world, Starburst is consistently connected to free spins offers.

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 bonuses 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. Besides 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 downloaded and installed on iOS and Android phones and tablets.

As the leading slot games are based on advanced HTML5 technology, they are perfected 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 Feature in Slots

In addition to free spins given by the casino as part of a promotion, there is another type of free spin that 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.

FAQ


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

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 each casino. For more information, check the casino’s promotions terms and conditions.

There are still some UK casinos that offer bonuses without a deposit, but these are typically available for VIP players only.

Occasionally new casinos will offer better a substantial number of free spins to attract new 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.
