The free spins are valued at 10p each and can be used on the popular online slot game, Bigger Bass Splash, which has an RTP of 96.50%.
It’s a substantial bonus, all of which can be used on slots, and whether you are planning to play through the bonus on the desktop site or LeoVegas mobile app, you won’t be disappointed.
We found the desktop casino page to be well-organised and easy to navigate, while the app has scored highly among both Android and iOS users.

Bet365 are giving new customers up to 500 free spins when they join, easily the largest amount of free spins available at any slots site.
There are no wagering requirements from any winnings generated and the free spins can be used on any of the following games: Book of Horus, Curse of the Bayou, Magic Forge and Wrath of the Deep.
If it all sounds too good to be true, that’s cause there is one large caveat, and that is the number of free spins a player receives is randomised.

Once players have signed up and made a deposit of at least £10, they get access to the free spins giveaway machine, where they can win 5, 10, 20 or 50 free spins over 10 days.
That means if bettors are unlucky, you could end up with only 50 free spins, although the likelihood is that players will claim at least 100 free spins.
Bet365 bettors can also receive free spins from the free-to-play prize matcher, which hands out free spins, free bets or gold chips once per day.

New UK casino BetMGM launched in 2023 and the US casino giants have very quickly built on their reputation, earning a reputation as one of the best payout online casinos and offering one of the biggest libraries of slot games.
I like how BetMGM split the online slots into various categories, making it easier to find what you are looking for. There’s a great selection of progressive jackpot titles, and the chance to land a massive payout from the MGM Millions games is why many online slots players come to BetMGM.

I found the website layout to be far more modern and up-to-date than most rival slot sites, making the overall gameplay experience much slicker.
Some customers have reported slow withdrawal times when attempting to collect their winnings, so it’s important to keep that in mind as you play.

The return to player (RTP) of a slot game is a useful indicator of the kind of return bettors can expect from a game. A higher RTP means a potentially higher return, although the percentage is worked out based on thousands of plays by numerous users, not just a single player.
The best slot sites now display a game’s RTP, but Sky Vegas have taken that a step further by allowing players to filter through slot games by RTP. Users can also select what level of volatility they’d prefer, what kind of bonus rounds they like and the theme of a game, making it very easy to find games to suit every type of online slot player.

Unfortunately, bettors can’t use the huge haul of 250 free spins that come with the Sky Vegas welcome offer to play the higher RTP slots, but those free spins can be used on progressive jackpot titles, and there’s no wagering attached to any winnings generated, making it a strong sign-up bonus overall.
We also like Sky Vegas for their great range of exclusive slot games, their strong slots apps and the seamless integration with Sky Bet and other gambling services on the platform.

New customers using the Pub Casino bonus code can claim the welcome offer worth a 100 per cent deposit match on their first deposit, up to £100. But any winnings generated from the bonus funds will carry a 40x wagering requirement.

No one does a better job of self-promotion than Paddy Power, but they back up all their talk with one of the best places to play online slots, boasting a small but strong library of games, fast withdrawals, a good app (albeit only on iOS) and regular offers for existing customers.
Punters who use Paddy Power’s sportbook will regularly find bet and get offers for selected slot titles, while the free-to-play Paddy’s Wonder Wheel hands out no deposit free spins on occasions.
But the best source for free spins on Paddy Power is through the rewards club, which offers bettors the chance to claim 25 free spins each and every week.
open image in galleryPaddy’s Rewards Club hands out up to 25 free spins each week to online slot players (The Independent)To claim the maximum of 25 free spins, bettors will need to wager £50 or more on slots. Those players who prefer to wager less can still claim a weekly bonus with Paddy Power handing out five free spins to users who wager a minimum of £10 between Monday and 23.59 on a Sunday.
The free spins are valued at 10p each and can only be used on the first game launched. However, there are no restrictions on which games the free spins can be used for.
For those bettors who enjoy getting a little extra from their slot sites, Paddy Power is an excellent choice and new customers can start off by claiming 160 free spins with the latest Paddy Power Games welcome offer.

Ladbrokes set the standard currently as the best slots app in the UK with their mobile platform scoring very highly with both iOS and Android users.
Ladbrokes gets a 4.7 out of 5 rating on Apple’s App Store, while Google Play users score it a 4.5, edging ahead of their sister gambling outfit, Coral, who sit at 4.4 on Android.
Bettors will find over 3,000 of the best online slots housed on the Ladbrokes app, which receives praise from bettors for its range of daily free-to-play games and regular slot offers.

Bettors can join Ladbrokes via the slots app and unlock the 100 free spins that come with the welcome offer. While you can get more free spins elsewhere, these free spins carry no wagering requirements, while punters have a bigger choice of games to use the bonus on than some rival slot sites provide.

Ladbrokes Casino BonusBest Online Slot Site of the Week: Coral
Coral have steadily established themselves as one of the top slot sites in the country, with their online casino featuring a well-stocked library of the best online slots and several achievable offers, all available on a top-rated mobile app or functional desktop site.
Punters can grab an exclusive Coral casino bonus offer from The Independent, consisting of 100 free spins when they wager £10, which is far better for slot players than the £30 in bonus funds that comes with the standard welcome offer.
Once registration is complete, there are over 4,500 slot games to choose from, with Coral often getting new releases early, such as the latest edition of the Big Bass franchise, ‘Big Bass: Christmas Frozen Lake’.
Coral boasts one of the best slot apps on the market with an average rating of 4.6 on Apple’s App Store and 4.4 on Google Play, although some users have reported issues with certain games on the app.
The best bit about Coral, though, has to be how many ways you can grab some free spins for online slots. There’s the free-to-play Rewards Grabber, which hands out free spins and other prizes on a daily basis.
The Smart Rewards promotion offers daily and monthly prizes consisting of free spins, while bettors can accumulate Coral Coins by taking part in various promotions and redeeming the coins for free spins.
That’s not all, with bettors able to claim free spins when they bet on certain sports and enter slot tournaments for free with the chance to win more free spins or cash prizes.
How We Rank Online Slots UK
I have reviewed dozens of casinos in my bid to find the best slots sites. Through my research, I believe I have compiled an unbiased, thorough, and well-measured list to help online players find the right site for them, depending on their various personal criteria.
I was able to do this thanks to my own strict criteria. Each site met various requirements, including providing high-value promotions and offers alongside a wide variety of games and payment methods, with efficient customer service, overall enjoyment of gameplay and the correct licensing and regulations according to the UKGC.
To create a full-rounded review, I spent plenty of time on each of the slots sites, as well as reading online reviews from other customers. Here’s a full breakdown of the full review method:
1. Quality and Value of Welcome Offers
It’s easy to be hooked by the headline on a casino bonus. Some of these offers claim to be worth hundreds of pounds, but upon further investigation, they aren’t as lucrative as they first appear. A £100 bonus that comes with 10x wagering and no slot exclusions is far more valuable than a £500 offer with 50x wagering and capped wins.
The Independent’s in-house gambling experts and I consider everything from wagering requirements, time limits and eligible deposit methods.
All the offers from slot sites we’ve mentioned have been tested to determine how easy or hard they are to claim. Only those welcome offers that are fair, transparent, and truly beneficial to earn a place on our best slot sites list.
2. Quantity and Quality of Online Slots
Having a large library of slot games is one thing, but we also like to look at the quality, diversity, and freshness of each slot collection. We explore whether the site offers classic 3-reel slots, branded titles, jackpot slots, popular Megaways games, and new releases from top developers like NetEnt, Big Time Gaming, and Play’n GO.
Once you’ve found a slot site offering the best online slots, it's time to assess how easy it is to find these games and how they function on mobile devices. These are two key elements to pair with the size of the slot games collection.
If a site features the latest trending slots alongside old-school favourites and niche options, all of which are easily accessible and responsive on mobile, then it likely makes our list.
3. Promotions for Existing Players
The best online slot sites offer way more than just a good sign up offer. We monitor each casino's promotions hub to assess how often new offers appear.
Promotions such as daily free spins, seasonal slot tournaments, cashback deals, or bonus drops tied to specific slot games are always a welcome addition to any slot site.
Much like the welcome offers, we check to see how fair and transparent each offer is, assessing whether they are actually worth a punter’s time.

Slot Bonuses & Welcome Offers
4. Trusted and Convenient Payment Methods
Fast, secure payments are a huge part of what makes a slot site worth using. We only recommend sites that offer a selection of reliable payment options familiar to UK players.
With so much choice when it comes to complete financial transactions online, there’s no excuse for the best slot sites not to offers various payment methods, including debit cards, e-wallets, bank transfer services, Apple and Google Pay and Paysafecard.

Slots Bankroll Management Tips
5. Friendly, Fast-Acting Customer Support
Great customer support should mean bettors are getting fast and effective support when they need it. We put each slot site’s support team to the test, checking how quickly they respond, how knowledgeable their agents are, and whether help is available around the clock.
We also review the help centre content. Is there a useful FAQ section? Can players find help with deposits, withdrawals, account issues, or safer gambling without needing to contact support? Those slot sites that provide an effective customer service portal and clear self-help options are rewarded.
6. Full Licensing and Player Protection
All recommended slot sites are fully licensed by the UK Gambling Commission (UKGC), ensuring compliance with strict rules on data protection, responsible marketing, game fairness, and player safety.
If a slot site doesn’t have a license, it won’t feature on any of our gambling-related pages.
We double-check licence details and look for signs of additional regulatory oversight, such as membership with IBAS (Independent Betting Adjudication Service) or partnerships with testing agencies like eCOGRA. If a slot site isn’t transparent about its licence or regulatory commitments, we won’t feature it.
7. Commitment to Safer Gambling
We consider responsible gambling tools a core ranking factor when reviewing online slot sites.
Each operator is evaluated on its safer gambling measures, including deposit limits, time controls and self-exclusion options.
We also verify participation in GAMSTOP, ensuring players can take permanent breaks when necessary. Just as importantly, we assess how visible and accessible these tools are.
The best slot sites proactively promote safer play and make support easy to find.
The Most Trusted Casinos for Online Slots UK
The Independent's team of gambling experts have had their say on which slot sites they would use, but what do the general public think?
We consider feedback from bettors when putting together our rankings for any article on online casinos or sportsbooks with Trustpilot scores being a good indicator of a worthwhile slot sites.
Some reviews on Trustpilot can be disingenuous or fail to reflect the overall quality of a slot site, hence why we don’t base our rankings solely on their scores. But the Trustpilot ratings are still useful to gauge how popular and worthwhile an online casino is.
Here are five of the highest-rated slot sites in the UK, based solely on Trustpilot ratings:

Best Payment Options for Slot Sites
There tend to be plenty of options available when it comes to selecting your preferred payment method on an online slots site. Essentially, you want to make sure deposits and withdrawals are speedy and that all exchanges are secure.
I also recommend looking out for minimum deposit casinos to avoid putting down a large amount on your first deposit, while still qualifying for all the benefits of a new customer.
- Debit cards: The most widely accepted payment method on slot sites is debit card. Payments made by debit card tend to be reliable and are often processed quickly, although some online casinos can take a few business days to clear withdrawals. Some slot sites even give you free spins for registering your debit card.
- E-wallets: Third-party sites and e-wallets offer speedy transactions with enhanced security as the middleman, meaning you are not sharing bank details with the slots site directly. PayPal casino sites can sometimes charge a transaction fee, while welcome offers are rarely eligible from Skrill casino sites. However, always read the terms and conditions before using this method.
- Mobile banking: Google Pay and Apple Pay casinos are on the rise, although they are not yet widespread. These modern payment methods are linked to your debit card but it’s quicker and more convenient than using a bank card and there’s no need to share card details with the casino.
- Trustly: Trustly is an open bank payment provider that works in a similar way to bank transfers, only much faster. Trustly casinos are increasingly common, offering bettors direct -account-to-account instant payments without the need to log in to your online bank account.
- By phone bill: While pay by mobile casino sites may sound a little strange, this can often be the quickest and easiest payment method. All you need to do is enter the deposit amount and your mobile number and the casino will send you a text message with a verification code. The issue with this method is that you can’t make withdrawals, and the deposit limit tends to be low.
- Bank transfers: This method is particularly useful for high rollers who are transferring large sums of money, however, it is one of the slowest methods too, even at a fast withdrawal casino.
- Prepaid card: Prepaid cards are widely accepted among online casinos. Paysafecard casinos are one of the most popular ways for users to deposit due to the privacy and security offered, requiring only a 16-digit code to add funds into an online account. However, there’s no way to withdraw funds using this method.

Types of Slot Games at UK Slot Sites
The best slot sites have thousands of games for punters to choose from, split into several categories to help users find the type of online slot they prefer. Here’s a look at the different types of online slots available:
Classic Slots: Traditional Gaming at Online Slot Sites
Classic slots remain popular at slot sites thanks to the nostalgic experience of playing at a traditional land-based casino machines. These online slots typically feature three reels with simple payline structures and iconic symbols like fruits, sevens, and liberty bells.
Most slot sites carry classic titles such as Fire Joker and 7s on Fire, which appeal to players seeking straightforward gameplay without complex bonus features. These online slots offer lower volatility, making them ideal entry points for newcomers.
Video Slots: The Modern Standard Across Slot Sites
Video slots have become the dominant offering at nearly all slot sites and make up the majority of slot games available to play. These modern online slots typically feature five reels with multiple paylines, advanced graphics, and immersive bonus features.
Some of the most popular games on slot sites, like Starburst and Gonzo's Quest, are video slots and they’ve gained a strong following thanks to the variety available, their superior RTP rates and engaging gameplay mechanics.
Progressive Jackpot Slots: Life-Changing Slot Prizes
Progressive jackpot slots represent the pinnacle of high-stakes online slots gaming, with the best slot sites offering jackpots that can reach millions of pounds. These online slots pool contributions from players across multiple slot sites, creating prize funds that grow continuously until won.
The most reputable slot sites offer tiered progressive systems through games like Mega Moolah, providing multiple jackpot levels. These online slots typically allocate 1-4% of each wager to progressive prize pools, though some slot sites require maximum bets to qualify for top-tier jackpots.

Megaways Slots: Revolutionary Online Slot Gaming
Megaways slots offer a unique take on online slots thanks to the innovative random reel modifier system. The best slot sites now dedicate entire sections to these dynamic games, which feature up to six reels with variable symbol displays, creating anywhere from 64 to 117,649 potential paylines.
Megaways have proven extremely popular on slot sites due to the games typically offering above-average RTP rates exceeding 96%. However, bettors should be aware these games have a high variance, meaning wins are less frequent, which could put offer some bettors with a small bankroll.
Tips on How to Play Online Slots
I want to ensure our readers are ahead of the curve when it comes to playing online slots, so here’s my best bits of playing UK online slots:
- Claim welcome bonuses: These are a great way to get a head start on your game, often boosting your betting bankroll with deposit matches or handing you free spins. Always read the terms and conditions on any offer with wagering requirements as it can be tricky to turn a bonus into real cash if the wagering requirements are particularly high. One of the best times to play slots can be with your welcome bonus, but look out for the terms and conditions to maximise your winnings.
- Practice: It’s important when playing any online casino game to make sure you’re familiar with the process before any stakes are introduced. If you want to know how to play online slots using the best slot tips, I recommend practising, either by using free online slot games or by using any free spins that might be available to you first, before staking your own money.
- Budget: Slots should be fun and entertaining, so the best way to keep it that way is by having a strict and realistic budget in mind. Having slots bankroll management skills keep you disciplined so you are more likely to find that online slot games remain a positive and responsible experience.
- RTP: Refers to the casino phrase, ‘return to player’. If you’re wondering, ‘What is RTP?’ The key fact is the higher RTP a game has the better value for money the game is likely to be over a period of time. This is a great way to decide which slots you should invest in.
- Games: There are different types of slots available for customers. Have a look at the catalogue of games available and pick the slot game that suits your preference or budget. You may choose a game based on potential earnings or a particular theme, such as films or TV shows.
- Promotions: Always seek out sites and games that offer you the most value for your money. Usually, this comes in the form of regular bonuses and offers. While welcome bonuses will be provided by almost every online slot site, existing customer promotions are less widespread. No wagering free spins, profit boosts and deposit bonuses are promotions I suggest you check for at an online casino before signing up.

Online Slots: Game of the Week
Yogi Bear
Many of us enjoyed watching Yogi Bear back in the day and there’s now a chance to play a slot game based at Jellystone Park. It’s great to experience some proper cartoon nostalgia and see some old faces including Yogi, Boo Boo and Ranger Smith.
Blueprint Gaming are behind this medium volatility slot which has a 95 per cent RTP, with ten paylines and five reels and a maximum win potential of 5,000x.
We’re especially fond of the cash collect feature, where big prizes can be won, and there’s also a super bonus round where free spins can be landed. The presence of modifiers mean that payout potential can be boosted too.
Responsible Gambling
Slot sites are among the most visited gambling platforms in the UK, alongside online casinos, poker sites, betting sites UK and bingo sites. With eye-catching games, offers and more, it’s easy to be drawn in.
Responsible gambling must always be the priority. While licensed casinos are required to uphold strict UK Gambling Commission standards, players also have a responsibility to manage their behaviour and spending habits.
The safest way to enjoy online slots or casino games is to maintain clear boundaries. It’s not just down to operators to create a secure environment — players need to understand and respect their own limits, and recognise when those limits are being tested.
It’s particularly important not to get carried away by casino offers or free bet offers, both of which are available in abundance on gambling sites, but must be approached with caution.
In the UK, there are a number of gambling addiction charities ready and prepared to help you with counselling, support groups and practical advice on how to help you recover if you do lose control:
- NHS Help
- Gamblers Anonymous
- GamStop
- UKGC Safer Gambling

FAQs For Slot Sites UK

The best choice ultimately depends on what you value most. It may be worth trying a couple of operators from our list to see which one suits your style of play.

Slot sites will often have promotions referencing free spins. These are exactly as they sound: spins on a slot game that don’t cost bettors any money to use. Usually, the free spins are limited to a certain online slot game and each spin will be worth a set amount. Slot sites will state how many free spins you receive in the terms and conditions, and whether any winnings from the free spins carry any wagering requirements.

Rules relating to slot bonuses prohibit the purchase of bonus rounds or free spins on UK slot sites. You may read reviews of slot games and see talk of being able to buy bonus rounds on certain online slots, but this will not be an option for the UK version of that game.
