There are thousands of online video slots available at multiple UK online casinos. Our guide will help you understand what video slots are, how they work and how to find the best ones.
In the simplest terms, video slots are slot machines that feature a video screen instead of mechanical reels. You can play them on desktop casino sites and online casino apps.
This differentiation was born in land-based casinos, where video slot machines first rose to prominence in the 1980s. In this setting, video slots provide the clear advantage of faster gameplay over games with reels.
When you play an online slot game, you are technically always playing a video slot because all games are digital without mechanical parts. Even so, people often use the term “video slots” to classify regular online slots, while other categories get their own names, such as jackpot slots or classic slots. Mobile slots are the next step in the evolution of video slots.
If you’re looking for the best video slots online, this is the page for you. Our recommended online casinos provide access to the best slot games of all time at the best online casinos. There are thousands of slots available, so choosing a list of the absolute best is entirely subjective. Even so, the following popular games will give you an amazing time playing video slots online.
NetEnt’s vampire-themed Bloodsuckers has been impressing players since 2009 and remains an outstanding slot game. With five reels and 25 paylines, this game has features, such as bonus spins, with a 3x multiplier and a Vampire Slaying Bonus-picking feature. However, this game is all about that 98% RTP, which puts Bloodsuckers in the top bracket of best payout slots.
Known for its bouncy cartoon design, Reactoonz from Play’n GO is a fun-looking video slot that uses an animated alien theme to good effect. It has a dynamic base game where each win charges a meter to potentially land one of the five Quantum features (transforming wilds, low-value symbol upgrades, low-value symbol removals, and Gargantoon wilds). Using a 7x7 grid with cascading symbols mechanics, Reactoonz is constantly exciting.
Microgaming’s Thunderstruck II is an all-time classic with a fantastic math model. Its above-average RTP and high variance mean the wins flow regularly. Since 2010, Thunderstruck II has been the ultimate Norse mythology-themed slot that has spawned many imitators. The Great Hall of Spins bonus is legendary, providing different numbers of free spins depending on the trigger combination. Other features on the 5-reel slot include the 243 ways-to-win engine.
Proof that the best UK slots online do not need to be complicated to be successful, Starburst is a simple game that wows users with its visuals and slick gameplay.
NetEnt’s game is a bona fide classic and the most popular online slot ever made. Much of that success comes from the flexibility of Starburst, which offers something for all players. Spin over five reels and 10 paylines and soak in the space-style arcade theme. Starburst Wilds are your ticket to the big prizes, providing three re-spins and wild reels.
As the name suggests, this is the deluxe version of Novomatic’s Book of Ra, perhaps the best adventure-themed slot of all time. You get the standard “Book of” set up of five reels and 10 paylines as you attempt to plunder the treasures of ancient Egypt. Don’t be too put off by that below-average RTP, although the extreme volatility means this is the kind of slot where you bet all or nothing. If you’re willing to take the risk, Book of Ra Deluxe delivers with the excellent Free Games feature that offers expanding symbols for big wins.
Cast off and see if you can reel in a big prize with Fishin’ Frenzy, a popular Blueprint Gaming video slots game with a unique theme. Since arriving in 2014, the game has remained popular thanks to its simple gameplay. Yet, the high volatility means there is always excitement around the corner. Spin on five reels and bet on up to 10 paylines, with the bonus spins feature being your gateway to the fish-catching bonus round.
Wizard of Oz from SG Interactive is a popular video slot available at many UK online casinos. It takes a hugely popular theme and applies slick visuals and dynamic gameplay for an all-around solid video slots experience. With five reels and 30 paylines, Wizard of Oz has several bonus features, such as the Winged Monkey and Emerald City.
Some of the best online video slots of all time are based on well-known TV shows or movies, and The Goonies is among the greatest. Blueprint has taken a cult classic 80s film and turned it into a thrill ride of a slot with a massive 12 bonus features. On the five reels and 20 paylines, you get stacked wilds alongside the ability to trigger a bonus feature, such as free spins, multipliers, win spins, and more.
Book of Dead is one of Play’n GO's most important real money slots online, and one of the most popular video slots ever. You take control of Rich Wilde as he seeks ancient Egyptian treasures in an adventure setting. The five reels and 10 paylines point to a basic game, but Book of Dead is surprisingly flexible thanks to its free spins, which can potentially be triggered an unlimited number of times.

Video slots boast many of the same gameplay elements as other slot games. Players place a bet and spin reels featuring symbols of varying values. Wins come from landing winning combinations of those symbols or by triggering an online slots bonus round. Understanding the following core elements of the best video slot online games will enhance your experience further:
While all games are decided by random chance, having a fundamental knowledge of video slots may help you keep your bankroll longer. Below you can read our straightforward overview detailing the basics of online slots:
There are some of our preferred slots:
In the land-based casino slot industry, differentiating between video slots and a classic slot machine is easy. Video slots use a digital screen, while a classic slot machine is a mechanical device. However, in the online industry, all games are digital/virtual, so the differentiation is less obvious. The best mobile casino has the same game types.
Technically, all online slots are video slots. However, players and casinos still categorize video slots and classic slots differently.
Classic slots, which tend to be remakes of older, classic slot machines you'd find at a land-based casino, typically have basic gameplay and a much simpler structure. For example, fewer reels, fewer paylines, and mostly no bonus features like scatters and wilds you might find at a UK free spins casino. That makes them an ideal choice for beginners to online slots or players who like fast-paced, simple gameplay.
However, classic slots do lack some of the dynamic elements that make video slots so popular. One area where there is a clear difference between the two is in terms of design, audio, and theme. Online video slots have rich themes with impressive graphics and immersive soundtracks. On the other hand, classic slots can be less show but mainly substance.

Video slots are the most popular category at online casinos, so providers are constantly rolling out new games. Since we're still at the beginning of 2023, the most popular games this year have been released during the previous year. Below are some of the best online video slots that made their debut in 2022:
One of NetEnt’s new slots, Bee Hive Bonanza, is already grabbing the attention of players. It boasts the usual visual splendour and gameplay quality we expect from NetEnt. Bee Hive Bonanza plays on five reels and five paylines, making this an ideal video slot for beginners. However, other types of players will also be interested thanks to the game’s Avalanche symbols and free spins.
1x2 Gaming has a new video slot, released last year, called Mystery Woods. This game provides a solid jackpot that can net you up to 12,500x your stake. Five reels and 20 paylines are your starting point towards the prize pot, with additional features, such as wilds, mystery symbols, and free spins. It is also worth noting this game looks fantastic, adding fresh appeal to the well-worn enchanted forest genre.
Another visually stunning new video slot is Habanero’s Space Goonz, which has an alien theme with cute graphics and cartoon vibes. Luckily, the game backs up its cool looks with solid gameplay featuring exciting bonuses, such as free spins. On the slot's 5x4 reels, you’ll find modern graphics, immaculate theming, and much more.
Circular Arrow is taking a stab at an ancient Egypt slot with Ark of Ra, a new video slot with five reels, three rows, and 20 paylines. It takes a lot to stand out in this busy genre, but the Egyptian vibes of Ark of Ra admittedly look fantastic. We also like the Coin Collect feature that allows you to gather coins over winning spins and trigger a wild if you get enough.
Big Time Gaming is launching its next blockbuster slot, Castle of Terror, just in time for Halloween 2022. The horror visuals look good, and the 61,720x your stake jackpot is one of the higher fixed jackpots around. With its generous 96.73% RTP, expect the game also to be volatile.
UK bettors love video slots because of their variety, quality, and fun gameplay. Yet, numerous other advantages and benefits come with playing video slots over different types of slot games, including:

Absolutely. Video slots from top providers will always be decided by random chance through random number generator (RNG) software. Games are routinely checked to ensure they use a valid RNG, and no casino or provider can legally influence the outcome of a game.
No, unless there is a multi-RTP option. The game developer sets the return to player (RTP) percentage through the use of a random number generator (RNG). However, some slots come with variable RTPs which usually fit in a narrow range. The casino can choose to use any RTP but cannot change the payout rate otherwise.
Not at all. Reputable game providers use RNG technology to ensure all games are decided by random chance. Moreover, these developers allow their slots to be assessed by independent regulators to ensure there is no unfair influence on a game.
Yes, and many people do. You can even win a huge sum of money. But does that mean you will definitely win something? No, because all online slots are decided by random chance. You will be relying purely on luck when you play video slots.
