How We Rate UK Slot Sites
The leading online slot sites in the UK offer enticing sign-up bonuses, including free spins, along with regular slots promotions and rewards to enhance your chances of winning.
They also boast an extensive selection of slots, with diverse and engaging themes from innovative software providers, plus the latest releases and biggest jackpots.
When reviewing online slot sites, we always ensure they are licensed & regulated by the UK Gambling Commission to guarantee fair play and security.
While the responsiveness of customer support and variety of payment options are other key considerations in our evaluation of the best UK slot sites.
Our Picks for the Best Online Slot Sites December 2024
While there are hundreds of online slot sites to choose from in the UK, our experts led by Ana Dimitrijevic have handpicked what they consider the best based upon certain criteria:
"My background in software development for online slots has provided me with unique insights into what makes these games both engaging and entertaining. As an avid slots’ player myself, I can also evaluate and appreciate slot games from the player’s perspective, enabling me to understand what captivates fellow slots enthusiasts."
Best Slot Sites for Progressive Jackpots
When it comes to massive jackpots, three online slot sites stand out with their extensive offerings of progressive jackpot pool games.
Mr Vegas Online Slots
Mr Vegas offers a huge selection of jackpot slots, with WowPot games like the atmospheric Wheel of Wishes, plus various Mega Moolah jackpot slots. Additionally they feature a large number of Dream Drop progressive slots, with Temple Tumble 2 being our favourite.
Key Features: Three exclusive ‘Wheel of Vegas’ jackpots for slot players and ‘Rainbow Fridays’ weekly cash rewards based on your previous week’s online slots play.
Unibet Online Slots
Unibet has an impressive array of over 100 progressive jackpot slot titles. This includes various popular WowPot slots like Sisters of Oz and Mega Moolah games such as Atlantean Treasures. They also offer an impressive variety of Dream Drop progressive jackpot slots, such as the wild-west themed Money Train Origins.
Key Features: An incredibly user-friendly games lobby, plus weekly £10k ‘Lucky Spin Riders’ tournaments on selected slot games.
BetMGM Online Slots
At BetMGM, you’ll not only find WowPot, Mega Moolah and Dream Drop jackpot slots, but also a selection of Jackpot King progressive jackpot games, such as Funky Pharaoh. They also offer exclusive MGM Millions games including slots favourites such as Starburst and Book of Dead, with a ‘mega’ progressive jackpot currently standing at £22 million.
Key Features: Their exclusive MGM Millions games allow you to play for jackpots on some classic slots which don’t offer progressive jackpots elsewhere.
Best Slot Sites for Megaways
Megaways is now such a popular online slots format that we have researched slot sites that offer the biggest variety of Megaways games.
Here are the Gambling.com top three picks for the best Megaways slot sites in the UK.
PartyCasino Online Slots
With almost 150 Megaways slots, you are spoilt for choice at PartyCasino, including favourites such as The Dog House Megaways and Madame Destiny Megaways, which are also part of Pragmatic Play’s ‘Drops & Wins’ promotion, with random prize drops every day.
Key Features: Slots players can spin the ‘Party Prizes MEGA Wheel’ for guaranteed daily rewards, plus regular opt-in slots tournaments and prizes.
Regal Wins Online Slots
Regal Wins is another online slot site to offer UK players around 150 Megaways slots, with classics such as Bonanza Megaways and jackpot Megaways slots, such as Diamond Mine Megaways Jackpot King and Wolf Blaze WowPot Megaways.
Key Features: Daily, weekly and monthly slots promotions, plus earn loyalty points every time you play slot games, which you can redeem for cash bonuses.
Mr Vegas Online Slots
Once again, Mr Vegas excels when it comes to their sheer number of slots, with over 200 Megaways titles such as Piggy Riches Megaways, plus jackpot Megaways games like Cash ‘N Riches Wowpot Megaways.
Key Features: The widest range of Megaways slots available in one place in the UK, plus regular slots promotions and a fair sign up bonus that gets paid out in 10% increments as you spin the reels.
Best Slot Sites for Promotions & Free Spins
Many UK slot sites offer customers regular online slots promotions and bonus spins to extend your gameplay or reward loyalty.
Here we detail what the slot experts at Gambling.com consider to be the best online slot UK promotions for December 2024:
Leo Vegas Online Slots
At Leo Vegas, UK players can get up to 50 free spins on Big Bass Splash (25 spins for your 1st & 2nd deposits) with no wagering requirements. They also offer regular free spins promotions and competitions for online slots players.
Key Features: There is a ‘Weekly Free Spins’ promo at Leo Vegas, with 30 x 10p free spins on Big Bass Bonanza every Thursday, plus another every Monday-Wednesday, with 10 x 20p free spins offered on Book of Dead.
MrQ Online Slots
Awarded ‘Slot Operator of the Year' in 2021, Mr Q offer slot players 75 free spins on Big Bass Splash, with no wagering requirements, when using our exclusive promo code: SPLASH75. Meanwhile, players of their Pragmatic Play slots such as Sweet Bonanza qualify for the popular ‘Drops & Wins’ promo, with its random daily prize drops.
Key Features: As official sponsors of Watford FC, Mr Q also offers all players 5 free spins on the Wild Swarm slot every time The Hornets win. There is also a ‘Daily Roulette Drop’ promotion which offers free spin prizes to players who have deposited £10 the previous week.
All British Casino Online Slots
Although All British Casino don't offer free spins for signing up, there is a 100% first deposit bonus of up to £100 free and UK slots players also benefit from 10% cashback on lost deposits, paid in real cash with no restrictions.
Key Features: Weekly ‘Marvellous Midweek’ offers, such as bonus spins when reloading, plus they regularly email customers with invites to online slots tournaments and challenges with cash prizes.
Types of Online Slots
The earliest online slots in the UK were quite simple, typically featuring five reels with three rows. The very first online video slot to include a bonus round, known as 'Reel ‘em In’, was introduced in 1996.
Fast forward nearly two decades, and today’s players are greeted with a new generation of casino slots, boasting diverse formats and features.
Fruit Machine Slots
Unsurprisingly, these slots draw inspiration from traditional pub fruit machines. They typically feature a retro style and are composed of either three or five reels, with basic graphics and sounds.
Reel King is a prime example of a traditional fruit machine slot game that has made the successful transition from pub kiosks to online slot sites.
Classic Slots
While NetEnt’s Gonzo’s Quest and Starburst are considered modern-day classics, purists often classify true classic slots as games like IGT’s Da Vinci Diamonds or Barcrest’s Action Bank.
Megaways Online Slots
Megaways slots utilise a dynamic reel system where the number of symbols on each reel changes every spin, resulting in a varying number of win lines.
With up to 117,649 ways to win on a single spin and a cost per spin starting as low as 10p, it's easy to see the appeal of this exciting Megaways mechanic.
Games like Fishin’ Frenzy Megaways and Wild Celebrity Bus Megaways demonstrate how this innovative feature can be integrated into popular online slots.
Slingo
A blend of slots and bingo, Slingo offers a unique gaming experience where players complete bingo-style grids with numbers spun on a slot reel.
The goal is to match numbers to complete winning lines ('slingos') and advance up the prize ladder towards a full-house and the top prize.
If that’s your thing, we recommend checking out the wide selection of Slingo games at All British Casino.
"Slingo has gained significant popularity, leading to the creation of franchised versions like Tetris Slingo, Britain's Got Talent Slingo and my favourite, Starburst Slingo."
High Volatility Online Slots
Nowadays, software developers are eager to create highly volatile slots, providing players with the opportunity for larger but less frequent wins.
Hacksaw Gaming, in particular, are renowned for their extremely volatile online slot games, with titles like Wanted Dead or A Wild and Cubes. These online slots offer a truly all-or-nothing experience, emphasising a high-risk, high-reward style of gameplay.
Maximum Win Online Slots
Many seasoned slot players have yet to hit ‘max win’ on one of the highest paying slots.
NetEnt were the first to break the 100k barrier with their Dead or Alive 2 offering a maximum pay-out of 111,111x your stake, later surpassing it with the release of Starburst XXXtreme at 200,000x.
However, Nolimit City's Tombstone RIP now tops the charts with an unprecedented 300,000x max payout, first hit soon after its release in 2022.
Such potential wins are among the reasons why Nolimit City slots have secured a place in the favourite online slots lists of many UK players.
Progressive Jackpot Slots
Progressive jackpot slots offer the chance for someone to win a substantial fortune, with each bet contributing a small portion to a continually growing jackpot.
There are various progressive jackpot pools that link games from the same software provider and keep increasing until one player lands the jackpot.
Once won, the jackpot returns to a seed value and begins increasing again.
Below, we detail the largest online slot network jackpots currently available, along with the best UK slot sites where you can play them.
Network Progressive Jackpot Tracker (December 2024)
The biggest online progressive jackpot payouts have mostly been won on the WowPot and Mega Moolah series of slot games.
Microgaming launched the safari-themed Mega Moolah progressive jackpot slot back in 2006 to much acclaim. In 2015, it paid out a £13.2 million jackpot to British soldier Jonathan Heywood at Betway from the minimum 25p stake.
Since its release, the game has expanded into a series of titles that all feed into the same jackpot, such as Absolootly Mad, which paid the largest Mega Moolah jackpot of £16.9 million in April 2021.
That huge win came just two weeks after a WowPot jackpot of £15.2 million won by a UK slots player on the Book of Atem online slot at 32Red. Watch:
However, WowPot regained its crown with a world-record online slots jackpot of £33 million, won in late 2023 on the aptly named Wheel of Wishes.
While the slots above contribute to shared network jackpot pools, the following are stand-alone games with their own progressive jackpots:
These individual slots can still pay out staggering jackpots, including the €17.9 million won on Mega Fortune by a Finnish player.
UK players have won jackpots of £6.3 million on Hall of Gods at Casumo, £6.2 million on Jackpot Giant at Gala Bingo and £5.1 million on Beach Life at Betfred.
