Read on to see our top choices of best slots for UK players or click the links below to quickly navigate to the relevant section for you.
Blood Suckers is my pick for the top slot for UK players. Its RTP is exceptionally high, but the gameplay, all-round experience and mobile version all contribute to making it my favourite online slot.
Blood Suckers is a dark Gothic slot that is inspired by the full range of vampire fiction. From Bella Lugosi's Dracula and the original Nosferatu to more modern depictions like Interview With A Vampire and Buffy.
This fun setting is backed up by solid gameplay. The game has two fun bonus games to vary the pace a bit and an excellent RTP of 98%. This means, on average, players will win back about £98 for every £100 they bet. The average for online slots is somewhere around 96%, so this is a marked improvement.

Why We Loved Blood Suckers
High RTP - RTP is crucial in terms of how long your bankroll will last. Blood Suckers slot has one of the highest RTPs for any UK slot, at 98%.
Fun setting - The slot has a fun setting, executed well with great art and fun animation.
Good on mobile - The mobile version of this slot is great, working well on screens of all sizes.
No list of slots is complete without at least one appearance from the Ancient Greek pantheon. Zeus II brings the god of thunder to the slot world with an Olympian setting and an unusual reel layout that goes 2-3-4-5-6-7. This creates 192 win ways.
The unique base gameplay of this Zeus-themed slot is supported by awesome bonus game design and easy-to-read artwork and animations.
Zeus III also has a solid RTP of 96.1% and rates very highly in PokerNews' review across the board. This slot is a great all-rounder that got five stars in every category except sound design, where it got four stars.

Why We Loved Zeus III
Awesome bonus games - Hitting the bonus game is a real treat as the various features and free spins help keep the game exciting.
Solid RTP - The RTP is solid, a very important feature that greatly affects how long your bankroll will last.
Great all-rounder - Zeus III scores well across all categories.
The Big Bass franchise is one of Pragmatic Play's absolute stalwarts. There are dozens of variants on the theme, with Big Bass Mission Fishin' being one of the most recent and one of the best.
The slot benefits from modern art, design, and development tools, plus one of the stranger takes on the fishing-themed slot. The art style, stealth boat, and Thomas Newman-esque soundtrack echo the tone of modern spy movies while still maintaining the franchise's freshwater-fishing setting. The result is a fun parodic tone that adds a light-hearted feel to the slot's atmosphere.
If you want to see why the Big Bass series of slots is so popular, this is a good place to start.

Why We Loved Big Bass Mission Fishin'
High RTP - RTP is one of the most important aspects of any slot. Big Bass Mission Fishin' has an excellent RTP of 97%.
Popular franchise - This is an easy slot to start out with in the very popular Big Bass franchise.
Cool theme - The setting combines the classic setting of a fishing trip with the iconography and tone of a spy film.
Dead or Alive 2 takes its cues from the revisionist Westerns of the late-20th Century. Peckinpah and Unforgiven were clearly in the designer's mind when they drew the rundown saloon town that appears behind the slot reels. This half-gritty, half-mythic setting is perfect for a slot that is geared around making the player feel like a quick-draw revolver artist.
The tone isn't the only selling point. Dead or Alive 2 comes with several bonus games (the choice of which can allow you to influence your overall volatility), and its high RTP of 96.82% is an important plus for the game as well.
This is definitely one of the best out of the many Western-themed slots out there.

Why We Loved Dead or Alive 2
High RTP of 96.82% - Solidly above average, this slot's RTP is a real draw.
Western shootout action - Speaking of draws, this slot's setting and gameplay will make you feel like a gunslinger.
Excellent bonus games - The variety of bonus games is great, and each one fits the theme perfectly.
The Wish Mastertakes its visual style from the animation of the 1980s. The images look hand-drawn, as do the many detailed animations. The sound design complements this, creating a consistent and immersive atmosphere.
As well as building a magical, nostalgic world, The Wish Master slot has a really solid RTP of 96.64% which is above the average RTP of 96%.
Like some of our other favourite slots, this one scores really well in its review, earning five stars in every category that we assessed it in. What lets it down (and why it isn't ranked higher in this list) is Wish Master's volatility, which is high and means payouts aren't frequent.

Why We Loved Wish Master
80s cartoon art style - Perfectly capturing the nostalgic tone of old cartoons.
All-round high score - Rated well on gameplay, graphics, and style.
Above average RTP - RTP is very important, affecting how far your bankroll can go. This slot's RTP of 96.6% is above average.
RTP or return to player is a way of expressing the vigorish of a slot. An RTP of 95% means that on average, for every pound you bet, you will get back 95p. On average here means your mathematical expectation in the very long term. Naturally, your mileage on the timescale of a single sitting will vary more widely.
White Rabbit Megaways is my favourite high-RTP slot. A handful of other games have a slightly higher RTP, but 97.72% is objectively very high for a slot. But it's the other features that make it my top pick. With a Megaways dynamic, 'Caterpillar' multipliers and the 'Feature Drop' system that allows you to purchase the free spins bonus, White Rabbit Megaways kept me fully engaged during my session.
The Alice in Wonderland setting is tailor-made (or should I say hatter-made) for slot games, furnishing the designers with wacky, distinct, and instantly recognisable characters.
Big Time Gaming has licensed the Megaways system for this game, which gives every spin a unique layout with a randomised number of symbols on each reel. All this, coupled with one of the highest RTPs in the business at 97.72% and high volatility (meaning the game tends to pay out bigger prizes less often on average), there's a lot about this slot that should lure a player down this rabbit hole.

Why We Loved White Rabbit Megaways
High RTP - RTP makes all the difference to the longevity of your bankroll. White Rabbit Megaways has one of the highest RTPs for any UK slot, at 97.72%.
Megaways system - The Megaways system is slick and keeps things interesting by varying the base gameplay.
Recognisable theme - The world of Alice in Wonderland is realised here in a unique and enjoyable way.
Jackpot slots are slots that have an additional prize pool from which players can win especially large prizes. Progressive jackpot games take this a step further, with a lottery-style pool or pools that grow with every spin made by every player and jackpot prizes based on the size of the relevant pool.
Divine Fortune isn't just a slot you load up hoping to hit the jackpot. With a strong 96.59% RTP, smooth gameplay and engaging bonus features, it's enjoyable in its own right. The progressive jackpot round is the real highlight, though.
I felt the re-spin mechanic created genuine tension and excitement, making every spin feel like you could be close to a colossal win. If you fail at hitting the Mega Jackpot, the Minor and Major Jackpots are worthwhile consolation prizes.
This game takes you back to the times of the Ancient Greeks, where mythical God's, gold fortunes and legendary creatures set the scene for a hugely popular jackpot slot. Divine Fortune lives up to its name, with a huge Mega Jackpot on offer.
In total, there are three jackpots; Mega, Major and Minor. In the jackpot bonus feature (triggered by landing three or more bonus symbols), you must fill entire rows with gold coins bingo-style to secure one of the hefty prizes on offer.
Away from the life-changing jackpots, the base game itself still provides enough excitement for the game to be enjoyable. If you're based in the UK and want a fun all-round slot with a range of jackpots, Divine Fortune is an excellent choice for you.

Why We Loved Divine Fortune
Progressive jackpot - Every eligible spin by any player adds to three growing jackpots.
Engaging bonus jackpot feature - Re-spin to fill rows with gold coins until you strike out, or secure one of three jackpots.
Smooth Gameplay - Smooth gameplay that's engaging and reliable.
Bonus features are the spice and seasoning of the slot world. They help to control the overall pace of the game and introduce intermittent variations to the gameplay. They're also usually where the biggest prizes are awarded.
While testing Vikings Go Bezerk, I didn't feel like I was playing a slot game (not a conventional one anyway). Instead, it felt like a computer game, with exceptional graphics and detailed gameplay. The 'Rage' feature was my favourite in-game bonus, with each Viking character's rage meter increasing every time it wins a battle. A full rage meter equals free spins! If you are growing tired of conventional slots, this one's for you.
When it comes to beautiful visuals and complex, varied, and intricately animated bonus games, there are few publishers out there that can keep up with Yggdrasil Gaming. The company's slots are always masterpieces of worldbuilding and design, and Vikings Go Berzerk is no exception. Its visuals are startling, everything gets its own detailed animation, and the game has multiple bonus games, each of which has gameplay that is cleverly themed around the Viking world.
With an RTP of 96.10%, Vikings Go Berzerk is only a little above average. However, it more than makes up for that fact with its atmosphere and style.

Gonzo's Quest is the most popular slot for UK players.
With his oversized head and adventurous spirit, Gonzo the conquistador entered players' hearts in 2013 with the release of Gonzo's Quest. Over a decade later, his slot remains one of the most popular in the world.
The RTP is very average at 95.97% but the artwork and spirit of Gonzo's Quest still resonates with audiences.

Why We Loved Gonzo's Quest
Staying power - Gonzo's Quest has been one of the most popular slots in the world for over a decade.
Tropical locales - The South American jungle setting and Aztec temple backdrop entice players in.
Gonzo himself - Gonzo is a fun little companion who stands by the reels and reacts to the player's spins.
There are so many different factors when it comes to what makes a slot great. Many are decent, but the very best slots stand out for a variety of reasons. In this section, we'll quickly run through how we came to our decisions and why we included these slots in our lists.
Return to Player (RTP) is arguably the most important metric for any real money online slot. This is because the figure directly relates to how much a player can expect to get back in returns over a long period of time.
Therefore, the highest RTP slots are going to lose you less over several sessions. Of course, it's just an average figure. So over a day, month or year it's still theoretically possible to be in profit, but for the overwhelming majority of players, they'll lose money over the course of their slot-playing careers.
Picking higher-RTP slots helps you to mitigate some of the house edge, and you'll see your balance stretch a little further.
Theme
The theme of a slot is not quite as significant as RTP, given that it doesn't directly impact winnings. Nonetheless, it's still a factor that we consider to be important.
There's no point in playing slots if it's not enjoyable, and a large part of the fun is down to the theme and overall slot experience. One minute, you could be hunting scarabs in Egyptian-themed temples on Eye of Horus, while the next you're slaying Viking warriors on Thunderstruck II.
All slots we've mentioned have defined themes that help players fully engage with the game and immerse themselves into whatever the slot is based around.

The base game of a slot is the bread and butter, but nobody gets out of bed to just play for that. Most of us strive to hit the specific symbol combination that triggers the bonus feature.
These come in many different formats, but ultimately provide extra value from the base game and also different dynamics as well.
The slots we've picked mostly include some exciting bonus features that aren't just the standard 'X' free spins.
Gameplay
Slots are games at the end of the day, so gameplay has to be considered as a factor. Online slots in particular have evolved massively over the years, and we now have a range of different dynamics such as Megaways, expanding wilds and multipliers.
Gone are the days where you're simply clicking 'Spin' and mindlessly watching the standard 5x3 reels spin. The different dynamics now add unique gameplay styles that differentiate one slot from another and keeps things engaging.
Volatility
Slot volatility relates to how frequently a slot will pay out, rather than how much you might win. For instance, low-volatility slots tend to pay out more frequently, but the wins are usually smaller. It's the opposite with high-volatility slots, as they pay out less often but typically offer larger wins.
We consider each game's volatility before recommending it. Neither high, nor low-volatility slots are inherently better, but we often favour slots with lower volatility as they help make your money last longer. Ultimately, volatility is an important factor to consider alongside RTP, features and other aspects.
Most players nowadays have transitioned away from traditional desktop gaming, and instead now choose to play online casino games via mobile. If you're in the majority, you'll want to make sure your slot of choice is compatible with mobile. The experience is undoubtedly going to be different on a phone, but the very best slots are still just as enjoyable on mobile.
