We’ll also explain how we reviewed these offers, the types you can find in the UK, their pros and cons, the typical terms to expect, the best games to use them on, and more. Let’s begin.
With our years of experience, we’ve developed a surefire reviewing method for finding the best bonuses offering 20 free spins on registration with no deposit required.
To give you an insight into how we operate, we’ve decided to share our process with our readers, allowing you to conduct your own reserach when finding the best 20 free spins no deposit bonuses in GB:
The first step is to look for new 20 free spins no deposit bonuses online. We make a list of dozens of casinos offering this promotion to UK players.
The first step with each casino is researching its reputation and checking its safety and trustworthiness. We check that the site has a valid licence from a respected gambling authority, such as the UK Gambling Commission (UKGC), and offers reliable security features like SSL encryption. We also consult the opinions of long-term players so we can eliminate low-quality sites.
We check the fine print of each remaining online casino to eliminate all those with problematic terms and conditions. We review the overall T&Cs and the 20 free spins no deposit bonus terms. After that, we can further narrow down the list of sites we have to review in more detail.
It’s impossible to thoroughly check the quality of a promo without trying it out, which is why we create an account at each new online casino.
Upon registration, we proceed to claim the bonus. While we already know how the promo works, it’s important to ask for it and play a few games to see how it fares in practice.
We play the games that are eligible for use with the bonus and work towards completing the wagering requirements to see how difficult it is.
Once we’re done using the bonus, we analyse the entire experience and rate it.
With our ratings in hand, we can compare all the casinos and select the best sites offering 20 free spins no deposit bonuses.
This type of bonus is available in many different forms. To help you understand how to claim each one, we’re going to review every single type of 20 free spins bonus you can find among licensed casino brands in the United Kingdom. We’ve gathered all the essential information on how to claim these offers, along with specific details we recommend focusing on.
This is one of the easiest and most desired types of bonus. You register at a casino and receive the bonus spins immediately afterwards. You’re not required to make a deposit, but in most cases, the spins must be used on specific slots, and there is a time limit to use them all (typically a week). Licensed sites will also require you to verify your account in accordance with KYC procedures before you receive your spins.
Most of these no deposit bonuses have wagering requirements that require you to play through your bonus before you can withdraw it. They also have a winnings cap that limits the amount you can win from your bonus. Aztec Gems and 21 Сasino offer this promo to all new users entering the site.
These free spins on card registration is awarded when you provide your debit card information. The promo is still a no deposit bonus, and the valid card serves to confirm the identity of the account holder. However, you might still be required to make a deposit afterwards to claim your winnings. Whatever the case, the casino hopes the 20 free spins card registration bonus will entice players to use the site once they’ve used up the spins.
If you’re doing this at reputable sites, once you add card data, you don’t have to worry about your money’s safety, as the casino is not aiming to abuse it. They will protect this privacy data the same way they protect the rest of your personal information. You can try this offer on NetBet and Wild West Wins Casino.
Some casinos, like Netbet, require you to verify your phone number before claiming a bonus. These mobile casino free spins offers are not like 20 FS on card registration promos, as this is usually a standard part of the casino’s KYC process.
In most cases, you have to verify your phone number on registration. The casino sends an SMS with a unique code you need to input to verify your phone number and account. No additional requirements or investments are needed.
One of the main problems players have with free 20 spins no deposit bonuses is that they come with various T&Cs, most notably wagering requirements. That’s where the no wagering free spins offers, such as the one offered by Q88bets.com, distinguish themselves. They are among the best versions of the 20 free spin promo, as you get to use the spins and collect your winnings immediately; there’s no need to wager them before withdrawing.
You’re probably saying this sounds too good to be true, even in 2026. Unfortunately, you’re right. Even though there are no wagering requirements, there are still strings attached. In most cases, the winnings are capped to tiny amounts to ensure players won’t just take their winnings and leave. Despite all of this, the no wagering 20 free spin offers are still worth claiming, as they give you immediate access to your winnings.
This promotion is a variation of the standard 20 free spins casino bonus, which isn’t exactly free. Players are required to make a deposit to claim these bonuses, but they are often rewarded with additional perks, such as a matched deposit bonus.
The good news is that match deposit bonuses come with very low minimum deposit amounts. Brands like VIPs casino and Sparkle Slots are ready to provide this offer for players ready to invest £10 and grab the reward.
Some casinos offer existing customers free 20 spins instead of giving them to new ones for registration. These spins are usually tied to other promotions like VIP programmes, time-limited promos for special events like the holidays, and even ongoing bonuses.
The best part about these offers is that you can often claim them repeatedly. They come as part of daily, weekly, or monthly bonuses, sometimes in exchange for a deposit. Casinos such as Amigo Slots and SlotsKingdom offer these bonuses, but bear in mind that these deals are by invitation only.
Daily free spin bonuses are highly lucrative promos that some casinos in Great Britain offer to already registered players as part of other promotions or a welcome package. The latter is more common, and you usually get a match deposit bonus with many free spins, which you’re awarded automatically every day in equal instalments, 20 in this case.
If the bonus is awarded to existing players, it might be a reward for completing a deposit or a prize from a wheel mechanic, like in the case of Mad Slots. Daily free spins bonuses can be claimed weekly, though these offers can have additional requirements, such as maximum winning, wagering requirements and limited games available for the bonus.
Using the process described above, our experts have found and reviewed several dozen casino 20 FS offers. After evaluating the evidence, our team created a list of the best no deposit 20 free spins bonuses for UK players, which you can find below:
| Online Casino | 20 FS Welcome Offer | Recommended Slot | Min. Deposit | Wagering Req. |

| NetBet | 20 FS for adding valid mobile number | Book of Dead | No deposit | 40x |

Mad Slots offers up to 100 free spins with no deposit on sign up. It’s also a 20 Daily Free Spins no deposit bonus because the promo is awarded through the Wheel of Fortune (WOF), where you can win different amounts of free spins, but a prize is not guaranteed. The daily free spins no deposit promo is for ID-verified players only. Each spin is worth 10p. The offer lasts seven days, has a 30x wagering requirement, and the max win after wagering is capped at £10. Once you claim the offer, you get seven days to complete the requirements.
NetBet is offering 20 free spins on the Book of Dead slot to each new player. To get your 20 free spins, verify your phone number and register an account with the BOD22 bonus code. No deposit is required, but you must complete a 40x wagering requirement and can’t win more than £25. There’s also a £5 max bonus stake on the winnings, while the stake of each free spin is set to the minimum coin value of the game. Once you activate it, the spins will remain yours for seven days..
Wild West Wins Casino has a 20 free spins on registration “add card” no-deposit bonus reserved for new players on the Cowboy’s Gold slot. You don’t have to deposit but must fulfil the card verification requirement by providing a valid debit card. The max amount you can win from 10 spins is £8, meaning you can win only £16. Then you need to wager the winnings 65x (real money wagers don’t count), after which you can win up to £50. However, there’s a little catch that can increase the winnings cap; when you deposit, the maximum win cap will increase equal to the deposited amount, with £250 being the maximum.
21 Casino offers new players 20 free spins, no deposit required, plus one more spin in honour of its name. The spins are reserved for the Book of Dead slot. They come with the match deposit bonus, but you’re not required to deposit to get the free spins. You only need to register, verify your account (which might include providing documents), and opt-in for the bonus. You also need to be at least 18 years old and a resident of the UK. The spins are subject to a 35x wagering requirement, and winnings are capped at £100. You must use the spins within ten days.
SlotGames Casino offers a 20 spins on card registration bonus for the Aztec Gems slot to newly registered players. You only need to register and verify a valid debit card when prompted during the process, but the casino won’t take any money out. The bonus spins carry a 65x wagering requirement, and you can only convert £50 into real funds. Once you’re done, you can always deposit £10 or more to unlock a spin on the Mega Reel, where you can win up to 500 free spins for the Starburst slot. This feature is available on all Jumpman gaming sites.
Magic Red offers a 20 no wagering free spins bonus to newly registered players after they deposit a minimum of £10. After registration and deposit, the spins are awarded automatically, and you can use them only on the famous Big Bass Bonanza slot. The offer is valid for 24 hours, so claim it as soon as possible by registering and depositing all in one go. After claiming, you need to use the spins within one day, or they will expire. You can win up to £100.
Fabulous Vegas is offering a free spins no deposit bonus to each new player who joins its site. The 20 spins on registration, “add card” no deposit promo only requires you to register, verify, and add card details to receive your bonus; it does not require a deposit. If you decide to deposit later, make sure it’s £10 or more to get an extra 150 spins. The 20 spins carry a 30x wagering requirement you must complete in 7 days. The good news is that you can use the spins on all eligible games, usually 16 unique titles.
Casumo offers 20 free spins for real money as part of its 100% welcome bonus. To claim them, you need to register and make a deposit. The minimum deposit is the standard £10, and you must opt-in for the bonus. The spins are reserved for the Sahara Riches Cash Collect slot and carry a 30x wagering requirement. You must wager a maximum of £5 per spin or £0.50 per line. The spins expire after 30 days. The bonus also has payment method restrictions; you can’t use PayPal, ApplePay, Neteller, Skrill, Trustly, and Paysafecard to claim this offer.
Register, opt in, and play an eligible game to win up to 20 free spins on sign up at Betfred. This is a mystery promotion where you can win 3, 5, 10, 20, or 50 spins, but a prize is not guaranteed. The promo lasts until Betfred discontinues it. Each spin has a value of £0.10. As soon as you win free spins from the promo, you have to claim and use them by the end of the day (at 23:59 GMT), or they will expire.
Grosvenor’s Member Rewards programme offers 20 free spins for existing customers, or a £2 casino bonus, depending on your choice. You only need to be a registered member who has visited one of their venues in the last 90 days, deposited at least one, and played online in the last 30 days. You’ll get to claim 20 free spins daily, Monday to Friday, on specific dates (5 times in total), but you must use each bonus in 24 hours. The value of each spin is set at 10p, and you have to wager the winnings ten times.
20 free bonus spins are always an exciting promo to get on casino and bingo sites, but all of them come with specific terms. We recommend always reading through them, so you can claim bonuses properly and use them in the best way possible. These T&Cs are usually given in small print, so it’s not always apparent to players that the seemingly fantastic offer has limitations. To avoid any confusion about what you’re getting, here’s an overview of the most common terms and conditions to look out for:
Almost every new online casino 20 free spins no deposit bonus you find will be limited to specific games. However, many offers require you to use the spins on high-quality slot games, so we wanted to give you our take on some of the best ones, helping you find the right promo.
Starburst is a famous online slot designed by NetEnt. It features a simple 5-reel, 3-row setting with ten paylines and very few special features but a good 96.1% RTP and a max win of 500x. However, it offers frequent wins, and together with its expanding wilds that trigger respins, it’s no surprise that it has become one of the most popular slots ever. You can get 20 free spins on Starburst on several sites, including Slotgames.co.uk.
Rich Wilde and the Book of Dead slot game is one of Play’n GO’s most popular releases. It features a simple 5×3 grid and ten paylines. The RTP is relatively high, at 96.21%, but can vary depending on the casino, while the max win is 5,000x. The game boasts a unique free spin feature and expanding wilds. You can get 20 free spins on Book of Dead in many British casinos, including NetBet and 21Casino.
The Fluffy Favourites slot is a classic that remains popular more than 15 years after its initial release. It features a free spin bonus round, as well as 25 fixed paylines and a max payout of 5,000x. We don’t have a 20 free spins on Fluffy Favourites no deposit bonus available right now, but you can get an even better offer of 100 spins at Lucky Pants Bingo.
Age of the Gods is a popular Playtech slot with a free spin round and four progressive jackpots awarded randomly. The slot has 20 paylines and is centred around Greek mythology. It has a 95.02% RTP, high enough for a progressive jackpot slot. A 20 free spins on Age of Gods bonus is available at Betfred, as it’s one of the several eligible games on which you can use your spins.
Chilli Heat is a Pragmatic Play slot with 25 paylines, medium volatility, and a good RTP of 96.5%. The top prize is set at 2,512x the stake, but the game is mainly loved for its special features, including a wild, a jackpot, and a free spin round that offers up to 8 spins and can trigger the Money Respins feature. We don’t have a 20 free spins on Chilli Heat no deposit bonus at the moment, but we have a good selection of other free spin promos for the Chilli Heat slot.
Big Bass Bonanza is one of the most famous video slots from Pragmatic Play and can be found in a ton of British online casinos. It features a standard 5×3 grid with ten fixed paylines. There’s only one bonus round, but it’s collection-based, and you can also get various multipliers by landing wilds. The RTP is above average, 96.71%, while the top prize is 4,000x the stake. You can get 20 free spins on Big Bass Bonanza at Magic Red Casino.
NetEnt’s Gonzo’s Quest is the company’s “first platinum video slot game.” After 14 years on the scene, it’s still one of its most popular slots. The game is centred around Inca culture and follows the story of Gonzo the Conquistador. It has medium volatility and a 96% RTP. The Free Falls (free spins) are the game’s main feature. You can trigger more of them during the bonus round, and you can also get multipliers. We haven’t been able to find 20 free spins on Gonzo’s Quest with no deposit required, but we have other free spin offers for the Gonzo’s Quest slot.
108 Heroes is a classic Microgaming slot with medium volatility and a 96.56% RTP. It has 15 paylines and can reward up to 1,875x your bet. As the name might suggest, it’s centred around martial arts and Eastern lore. However, the central aspect is the free spins/bonus game combination, which can lead to many rewards. We don’t have a 20 free spins on 108 Heroes no deposit offer to give you at the moment, but there are plenty of other free spin promos for the 108 Heroes slot.
