Ranking Methodology: How Did We Select the Best UK Slots Sites?

Game Variety:

The best slot sites should provide different types of games. When we look for variety in online slots, we want themes, graphics, features, bonuses, and different ways to win.

There’s an opportunity for software providers to get creative, and we want to see if the casino in question has included innovative and exclusive titles.

Slots Bonuses:

A sure-fire way to enhance entertainment at online slot sites is to offer something extra. It could be through deposit bonuses, free spins, or a classic welcome bonus. What matters here is that you can use your bonus funds on slots and that the terms and conditions are reasonable.

Regular New Slot Games:

Another signifier of the best slot casinos is that they update their content. The industry is changing all the time, and to keep up, online casinos need to host the best and most popular slot games for you to enjoy.


Quite often, slot sites have large game catalogues. If there are thousands of online slots to play, you’ll need some help finding what you want or narrowing down the selection. That’s why navigation is essential.

We like it when we see search functions, labels, filters, and subcategories that will help you find exactly what you’re looking for.

Best Slot Sites in the UK – A Complete Roundup

1. Magic Red – Best Overall Slots Site UK

  • Search function, A-Z filter, and labels for new games
  • Welcome bonus with free spins
  • Slots bonus every Tuesday for regular players
  • Over 60 new slots added to the site recently
  • More than 750 slots from software providers like NetEnt and Pragmatic Play

Magic Red’s catalogue of over 750 slots has fruit, mythological, TV, sport, supernatural, and Vegas themes. Quite impressive – but that’s just the beginning.

With game studios like Pragmatic Play, NetEnt, and Microgaming that provide the slots, you know that quality and variety will be guaranteed. You’ll undoubtedly want to explore their slots lobby, and the search function and A-Z filter will help you do it hassle-free.

This casino made it to the top of our best online slots sites list as it’s good at more than one thing. It has variety, but it also provides new content regularly. New are games labelled with a green tag, and you’ll find fresh titles like Beriched and Book of Secrets 6.

Another area where Magic Red excels is slots promotions. The welcome bonus gets you free spins on the Starburst slot. There are offers for returning customers, too, with spins available every Tuesday. However, these are also for Starburst; we’d like to see other slot games included in their bonuses, too.

2. PlayOJO – Best Bonuses
  • Free spins on your 1st deposit
  • No wagering requirements to release bonus funds
  • Daily tournaments with free spin rewards
  • OJOplus feature, which gives you cashback every time you play slots
  • Around 2,000 slots in six categories, including new slots & jackpots

Out of the 3,000 casino games at PlayOjo, the majority – at approximately 2,000 – are slots.

We’re not just interested in slot sites that tick the quantity box, of course; fortunately, PlayOJO has quality, too. It’s evident in the range of games and themes, including fruit, gem, animal, magic, and music. Plus, you get features like bonus rounds, wilds, multipliers, and slots that pay both ways.

Unlike other casino sites, the operator doesn’t have wagering requirements. This means that – when you claim the welcome offer and receive your free spins – the winnings go straight to your cash balance and can be withdrawn.

One of our favourite things about PlayOJO is the OJOplus scheme. The more you play, the more you get rewarded. There’s a payout percentage for every slot, that is, the amount of your bet that you can expect to get back in theory. You can hover over a slot tile to see whether it is one, two, or three plus symbols, or check the info to see the exact percentage.

3. Grosvenor – Best Megaways Slots
  • About 69 Megaways slots to play, such as Rainbow Riches Megaways and 88 Fortunes
  • Slot games divided into eight subcategories, including new, originals, and top 20
  • Daily bonus spins giveaway on the Wheel of Wins

Grosvenor is an online and in-person UK casino with an excellent reputation. It’s been in the business for years, and it shows.

The online casino has several attractions, including the live dealer section. Slots fans will find the 69 Megaways games, like Dynamite Riches Megaways, particularly appealing.

Besides the Megaways category, you can find new, originals, classics, featured, and top 20 slots, so it’s easy to explore and discover some new gems. Another way to try something new is to explore their in-club slots that have arrived directly from their casino venues.

Moreover, Grosvenor the promotions are accessible and reasonable. The welcome bonus has a 5x wagering requirement for the main portion and 10x for the classic slot voucher. Slots contribute 100% to the requirement. Plus, every day, you get a chance to spin and win free spins.

4. LeoVegas – Best for Bonus Spins

  • 650+ slots, including top titles Cleopatra, Immortal Romance, Mega Moolah & Starburst
  • No deposit offer on Book of Dead
  • An additional welcome package with more spins and bonus funds
  • LeoVegas branded games

Like all good slot sites, LeoVegas has a dedicated slots section, as well as multiple categories. There are the top and newest games, as well as jackpots and must fall jackpots.

Games get updated frequently, although the pace seems to have slowed in recent months; so, we hope to see even more new games soon. The variety is there, though, with exclusive titles, such as Mustang Riches, LeoVegas Cluster Gems, and Star Supreme.

With over 650 slots to choose from, the LeoVegas spotlight feature comes in handy to find new favourites. Another brilliant way to explore the titles is the welcome offer. There are no-deposit bonus spins for Book of Dead, but you can also claim the welcome offer with the 35x wagering requirement.

5. – Best for Progressive Jackpot Games

  • About 20 progressive jackpots
  • Slots catalogue with sort, search function, filters, a-z listing, and subcategories
  • A slots-friendly welcome package with a deposit match and free spins

The bonus offers at are brilliant for slots players. The welcome package includes free spins that can be used on the Age of Gods games. You can qualify with a min deposit of £20, and the slot site also has a weekly offer with more spins on a variety of slots.

6. Bacana Play – Best for the Latest Slot Games

  • 2,800+ slots
  • Established in 2019
  • 62 new games, including Son of Midas and Skadi’s Hunt
  • Labels for new, popular, and jackpot slots, as well as theme and feature filters

Out of all the new slot sites, Bacana Play is the place to visit if you’re interested in getting access to the latest slots. You can view the newest additions by selecting the yellow tab or checking for the games labelled ‘new’. The catalogue is updated frequently, and we found 62 fresh titles, including Son of Midas and Skadi’s Hunt.

Besides the huge choice of games at this slot site, you can also get some extra value. With a min deposit of £10, you can get bonus funds and a small number of spins. Alternatively, with a minimum deposit of £50, which is a little larger than usual, you will get a smaller bonus and free spins for a year.

7. Mansion – Best Slots Tournaments

  • Drops and wins with daily and weekly prizes
  • More than 790 slots, including popular titles like Chilli Heat and Wolf Gold
  • Double your first deposit with the welcome offer
  • 17 new slots with jackpot titles such as Hot Gems Extreme

Mansion makes it onto our top slots sites list thanks to the excellent opportunities to win prizes.

There’s a weekly prize draw for players who deposit on Wednesdays. For an even bigger win, you can play your favourite qualifying slots and take part in weekly tournaments in their Drops & Wins promotion. Your highest value spin wins help you climb the leaderboard to secure that max bonus. All you need to do is opt-in and check the min and max bet amounts before you play.

You can use your bonus funds from the welcome deposit offer to explore the new games or the 790+ slots in the catalogue. It’s enough to keep all sorts of slot players entertained.

  • Large choice of mega jackpots like Big Irish Bucks
  • Free spins welcome bonus with no deposit
  • Refer-a-friend bonus
  • Wide variety of themes, including historical, Egyptian, space, animal, and Hollywood

The no deposit offer and welcome bonus at Mr Spin are built for slots fans. You can get free spins for the Reel Royalty slot just for signing up, and then you can access some bonus funds by triggering them with your first deposit. The welcome bonus is accessible and has wagering requirements of 20x playthrough, which is pretty reasonable.

Mr Spin made it to the number eight spot on our list mostly due to the excellent mega jackpots and flawless mobile optimisation. However, as the games are exclusively from In Touch, which runs the platform, some options are missing.

9. Red Kings Casino – Best VIP Programme

  • Select games by provider, category, the search function, or use the handy labels
  • Titles from popular game studios, including Pragmatic Play and Microgaming
  • Deposit bonus and Wolf Gold free spins for new players
  • VIP programme with free bonuses and a personal account manager

The VIP lounge at Red Kings is an attractive place to be. It gives you tailored free bonuses, so you can expect a little extra in your bankroll when playing here. We’re pleased that loyalty is valued, as the max bonus from the welcome offer is quite small.

When it comes to the choice of online slots, it’s one of the best casino sites, particularly regarding the list of their software providers. Red Kings Casino works with studios large and small, which means you’ll find the most popular slots, as well as some hidden gems that have awesome graphics and themes.

Finding your way around this slot site is a breeze because of the multiple ways you can narrow down your selection, so no time is wasted.

10. The Sun Vegas – Best Exclusive Slot Titles

  • Exclusive branded slots, Megaways, and Slingo games
  • Slots catalogue with four subcategories, search function, and labels for jackpots and hot picks
  • More than 100 new games, including Thai Flower Megaways and Brian Lara Sporting Legends

One of the newer UK slots sites, The Sun Vegas, keeps its content fresh, as can be seen from over 100 titles in the ‘new games’ category. Most of them are slots, so you’ll always have different options to explore.

We also like that you’ll find something here that you won’t find anywhere else. There are exclusive titles and branded slots, like The Sun Megaways and The Sun Cashpots.

This online casino didn’t secure a higher spot for UK slots sites because it works only with Playtech – nothing wrong with that, but it’s missing some of the top titles that you get from other software providers. Still, there’s variety in what they have, including Megaways, jackpots, and Slingo games.

What Are the Advantages of Playing Online Slot Games?

There are many advantages if you play slots online. First of all, it’s much more convenient than going to a casino. You can even access the sites on mobile, and play slots wherever you want.

You’re also more likely to find tournaments with slots, so you can have fun competing and might win a prize.

How Do I Pick the Best Slot Game?

When choosing a game at slot sites, there are several factors to consider.

Your playing style is an essential consideration – think about whether you like smaller, more frequent wins or whether you prefer to wait for something significant to come along. You can find out about a slot’s volatility and pick according to your preference.

RTP, or return to player, is another factor. Expressed as a percentage, it’s an average of how much the slot pays out. Higher numbers are better for you. Some online casinos tell you what games are on a hot or cold streak, which might impact your decision. Also, trying out some different types of slots with free spins (if they are available) will help you identify what you like.

What Types of Slots Can I Play?

Slots sites have many different types of games. You can find progressive jackpots, where a portion of each bet goes into a prize pot that can be won. Regular jackpots just have large amounts to win. You can also find Megaways, which have many pay lines and more reels than traditional slots. Additionally, there are Slingo games, a unique cross between slots and bingo.

Are Slots Sites Fair?

Yes, if you play at a legitimate online casino. All the casinos on our list are fair. They’re licensed by the UK Gambling Commission, which also regulates the site. It means the standards are set, including game fairness, and checked by an independent body. Moreover, random number generators or RNGs are used in slot games to prevent the game from being rigged.

How Do I Improve My Chances of Winning?

Slots are games of chance, which means there are no guaranteed ways to win. However, you can pick games with a high RTP, make sure you read the rules and paytable to understand how the slot works, bet what you can afford, and stop when you’ve had enough to get the most out of your experience.
