We’ve broken down the best slot games by category. Firstly, you’ll find the ten overall best games. Later, you’ll find the best Megaways games, the best progressive jackpot slots, and the best high RTP games.
Where To Play the Best Online Slots Games
Best Slot Games UK Players Can Enjoy (2024)
Money Train 4
Money Train 4, the latest instalment in Relax Gaming’s popular series, is a six-reel, six-row slot. The game offers even more win potential than its predecessors; a whopping 150,000x! Subsequently, it’s a highly volatile slot. If you can brave the swings, it’s one of the best slot games available right now, and it’s packed with action and excitement.
Available to play from as little as £0.10 – and as much as £6 – Money Train 4 is accessible to players on all budgets. The base game can produce some semi-decent wins. However, it’s the Money Cart Bonus you’ll want to look out for. This slots free spins offers a host of special modifiers.
The bonus round is a re-spin feature. Initially, you begin with three re-spins, and here, only cash symbols and modifiers can land. When they do, your re-spin counter resets back to three.
The most common modifier is the collector; when this symbol lands, it collects all cash values on the screen. Another is the payer, which adds a cash value to every square during the bonus. If you’re lucky, you can even land persistent modifiers, which perform their action every re-spin.
Things start to go crazy when you land the Collector Payer – as this collects all cash values on screen, then pays them – and this is the most common way of landing the game’s insane maximum win.
Dead or Alive II
Dead or Alive II is a video slot from NetEnt – and it’s quickly become one of the best online slot games available. A sequel to the original Dead or Alive, this action-packed sequel offers higher variance – and much larger win potential.
It’s a popular choice at mobile slots sites, and this five-reel, three-row game offers nine fixed paylines. Like its predecessor, Dead or Alive II is set in the Wild West, and the base game is identical to the original. Where things start to differ is in the bonus.
In the original Dead or Alive, there was just one free spins round. In Dead or Alive II, you’re given a choice of three; Train Heist, Old Saloon, and High Noon Saloon. It’s the High Noon Saloon most players choose, as this is where you can win up to a whopping 111,111x your stake – and here, sticky wilds have multipliers attached.
Book of Dead
Virtually all slot sites UK players can join offer Book of Dead from Play’n Go – one of the world’s leading slots providers. This blockbuster slot is arguably one of the most popular in the world. Players across the globe proclaim it to be one of their favourite slots. It’s also a massive hit with UK players who list it as one of their favourite UK slot games.
It follows the life of Rich Wilde – an explorer. The game is built around a five-reel, three-row layout, and there are ten fixed paylines.
Book of Dead is all about the bonus round – triggered by landing 3, 4, or 5 of the scatter symbols anywhere in view. Doing so awards ten free spins, and during the free games, one symbol is chosen to become the expanding symbol.
Landing three or more instances of this symbol anywhere in view causes it to expand and pay. If you manage to hit a full screen of the explorer, you’ll scoop the game’s maximum win; 5,000x! It’s no surprise this is widely considered one of the best UK slots.
Immortal Romance
Immortal Romance from Microgaming is a five-reel, three-row slot that carries a strong Twilight-esque vibe. Unlike most of the best UK slots games of all-time, Immortal Romance doesn’t use paylines, instead, relying on a 243-ways-to-win mechanic.
This vampire-themed game, often referred to as one of the best video slots ever made, offers a min/max bet range of £0.30 to £6.00 – so players on all budgets can enjoy the action.
The slot features the Wild Desire bonus, which can turn up to five reels wild, and the Chamber of Spins, where you can choose from four different free spins bonuses. Immortal Romance boasts a max win of 12,150x your stake, and it’s superbly made; the soundtrack is fantastic!
Jammin’ Jars
Jammin’ Jars was Push Gaming’s first title to really go mainstream when it was released as one of the developer’s new slot games – and it’s set on a unique 8×8 grid layout. The slot uses a cluster pays mechanic, with wins disappearing, and new symbols dropping down to take their place.
Bets range from £0.20 to £100, making it suitable for various budgets. The slot is packed with exciting features including a rainbow feature that triggers colossal symbols, a free spins round with sticky multiplier wilds, and the new online slots in the UK feature, Giga Jar.
During the Giga Jar bonus, increasing multiplier wilds jump around the screen. If they participate in a win, the multipliers can go crazy! Jammin’ Jars offers a maximum win of 20,000x, so it’s easy to see why it’s become so popular with punters!
Beast Mode
Beast Mode, a collaborative effort between Relax Gaming and the Casinogrounds community, is one of the best casino slot games available right now, in our opinion. The game is played on a giant 6×4 grid, and there are three exciting bonuses and features to choose from.
The first, is a free spins round with a multiplier that can reach up to 500x. Second, is a mystery symbols bonus, where sticky symbols can land and transform – and there’s also a lower variance coin collection bonus for those wanting less risk.
Beast Mode is certified by UK Gambling Commission-approved testing houses, so it’s available at the best online slot sites. Plus with a maximum win potential of 25,000x, it’s easy to see why it’s become such a hit!
Fat Banker
Fat Banker, the latest addition to Push Gaming’s popular “Fat” series, brings the glamour of the banking world to UK slots enthusiasts. OK, while that may not sound like the most enjoyable theme, Fat Banker is actually a solid slot. The action plays out on a giant 6×6 grid. There are 50 fixed paylines, and betting options cater to players on all budgets.
The free spins is where you’ll have the best shot of hitting the game’s 25,000x max win – and this is thanks to the expanding (fat) wild. Each time you collect four or five wilds, the sticky wild grows – and if you’re really lucky you can get a multiplier, too, which applies to all wins throughout the bonus!
Fire in the Hole
Fire in the Hole, a mining-themed slot from Nolimit City, is a high-variance game that’s played on a 6×6 grid. This action-packed slot features xBomb wild multipliers, a wild mining feature, and the explosive Lucky Wagon Free Spins round.
If you collect enough cash values during the bonus round – and unlock the grid using bombs – you could walk away with a huge maximum win of 60,000x your stake!
Big Bamboo
Big Bamboo, a tropical adventure from Push Gaming, takes you into a jungle filled with exotic animals. This five-reel, four-row slot uses a 1024-ways-to-win mechanic, and, like most of the developer’s slots, it’s very volatile; the maximum win potential is an impressive 50,000x.
There’s plenty of action in Big Bamboo, and landing three bonus symbols on the middle three reels triggers the main bonus round. You can then gamble, for a better bonus, or start with what you’ve got. During the bonus, the Towering Bamboo feature is present, which sees giant bamboo symbols added to the reels. If these land, they all reveal a matching symbol.
If you manage to land the gold coins, you can win up to 5,000x your bet – and that’s before the 10x multiplier comes into play! It’s a very volatile slot, but if you want to play the best slots games in the UK – Big Bamboo is one you won’t want to miss.
Tombstone RIP
One of the best slot games to come from Nolimit City’s development labs recently is Tombstone RIP. This fast-paced wild west-themed features a unique 2-3-3-3-1 reel layout and 108 paylines, which can expand through various game features. What really makes the game stand out, however, is the insane 300,000x maximum win – one of the highest in any non-progressive jackpot online slot.
Tombstone RIP is packed with bonuses including xNudge and xSplit wilds, scatters, and multipliers. The xNudge Wilds, for instance, can nudge symbols to create entire wild reels with increasing multipliers, adding to the potential for big wins.
The game also offers a range of free spins rounds like Hang ’em High and Boothill – each offering additional multipliers, wild transformations, and global multipliers. With an RTP of up to 96.08%, Tombstone RIP is a game any UK player should try at one of the top slot sites.
UK Slot Games with Highest RTP
When it comes to maximising your potential returns playing online slots, you should always look for games with a high RTP (return to player) percentage. The best RTP slots will ensure you can enjoy longer sessions. Below, we’ll show you five UK slots online available with the highest payout percentages.
Ugga Bugga – 99.07%
One of the highest RTP slots available in the UK right now is Playtech’s Ugga Bugga – featuring an insanely high 99.07% payout percentage. This exotic jungle-themed slot features an unconventional layout. The game boasts ten separate 3×1 reels, offering you multiple chances to win on each spin.
The game’s Hold feature allows you to lock in symbols. While it lacks a conventional bonus round, it’s possible to win up to 1,000x your bet thanks to wild and scatter symbols. Ugga Bugga is, without a doubt, one of the best paying slot games in the UK right now.
Book of 99 – 99.00%
Relax Gaming’s Book of 99 is another ultra-high RTP game. As the name suggests, it’s a “book” style game – similar to Book of Dead, and Book of Ra Deluxe. Also fitting with its name, Book of 99’s RTP is a flat 99% – well above the average in the online slots world today.
The game is designed around a five-reel, three-row layout, and there are ten fixed paylines. Like classic “book” games, the bonus round sees a symbol randomly chosen to expand and pay anywhere. Where it differs, however, is with its wild collection mechanic. During the base game, each time a wild lands on the reels, it’s collected and added to a metre.
Once you collect 99 wilds, the bonus round is triggered automatically. So there’s a sort of “guarantee” in the game; you know that if you play for long enough, you will trigger the bonus. With a maximum win of 5,000x and a really high RTP, Book of 99 is another slot well worth checking out.
1429 Uncharted Seas – 98.60%
Thunderkick’s 1429 Uncharted Seas is a slot that frequently finds itself listed in high RTP game posts – just as it is today. Boasting an impressive RTP of 98.6%, 1429 Uncharted Seas is designed around a five-reel, three-row layout with 25 fixed paylines.
The game is themed around a group of sailors, attempting to safely set sail on a wooden boat. It’s a simple-looking game, but it offers a surprisingly good level of action, despite the high RTP. During the base game, wilds that land expand, filling the reel.
If you manage to land 3, 4, or 5 of the scatter symbols anywhere in view, you’ll receive between 10 and 50 free spins. During these free spins, the expanding wild mechanic continues, with an increased number of wilds present on the reels.
Marching Legions – 98.12%
Marching Legions, a slot from Relax Gaming, is another really high RTP slot you can play. Its theoretical payout percentage is a healthy 98.12%, and it’s available at most UK slots sites.
Marching Legions uses a five-reel, three-row layout, and there are 243 ways to win. Matching three or more symbols from left to right will result in a win. The main highlight of the slot is the Marching Respins feature. This is triggered when a full stack of legionnaire wild symbols lands on any reel.
Once triggered, the reel turns wild, and that stack of wilds then jumps one reel to the left. A re-spin is then awarded, and on this re-spin, it’s possible for additional stacked wilds to land. The re-spins continue until there are no more stacked wilds on the screen!
Monopoly: The Big Event – 99.00%
Monopoly: The Big Event is a Barcrest-developed slot machine you may recognise if you used to play FOBTs in the UK. It’s based around the iconic board game and offers a fantastic RTP of up to 99%. It will be remembered as one of the best UK online slot games ever created.
Using a five-reel, three-row layout, Monopoly: The Big Event has 25 fixed paylines. There are two “Big Bet” options – a mechanic found in many of Barcrest’s slots. Landing three or more bonus symbols triggers the free spins round. This is where you can enjoy sticky wilds, symbol removals, multipliers, and guaranteed cash prizes!
Best Progressive Jackpot Slots
Mega Moolah
Mega Moolah is the best-known progressive jackpot slot ever made. It is a five-reel, three-row African safari-inspired slot that was developed by Microgaming. The game boasts various features, including wilds, free spins, and multipliers.
However, it’s the jackpot round that triggers randomly most players will be on the lookout for. The minimum jackpot in Mega Moolah is worth a cool £1,000,000. In the past, it’s risen to over £17 million! It’s no surprise this is widely considered one of the top online slot games ever.
Divine Fortune
Divine Fortune, a Greek-themed jackpot slot from NetEnt, may not offer jackpots worth as much as Mega Moolah or even some new slots games in the UK – but for many, it’s a more exciting game, as there are a couple of solid bonuses. Firstly, there’s a free spins feature, during which stacked wild reels can appear.
Secondly, there’s the main jackpot round itself; fill three rows with gold coins to walk away with the jackpot! So successful was Divine Fortune, NetEnt recently released a sequel; Divine Fortune Megaways!
Gladiator
This five-reel, 25-payline slot based on the 2008 film is one of the top progressive jackpot slot games online in the UK that players can enjoy. Developed by Playtech, the jackpot is seeded at a minimum of £1 million – and you can play from as little as 25p!
If you land three or more Coliseum scatter symbols you’ll trigger the free spins round, where extra wilds and scatters appear. If you land three gladiator symbols, you’ll trigger the jackpot round, where you’ll have a chance of winning the seven-figure prize!
Mega Fortune
Mega Fortune is another NetEnt jackpot slot that is built around a five-reel, three-row format. It offers one of the best online casino games UK players can enjoy, and the jackpot frequently surpasses the million-pound mark.
There’s a free spins bonus, where wins are multiplied by 5x, and a bonus game, where you get to spin a giant wheel and have a shot at the progressive! The life-changing progressive jackpot prize makes this one of the best online slot games to win.
Snake Arena DreamDrop
One of the new slot games in the UK, Snake Arena DreamDrop, from Relax Gaming, is a fast-paced, action-packed sequel to the original. This five-reel, five-row, 30-payline slot packs a venomous bite with its Dream Drop jackpots. Like all DreamDrop slots, the jackpot round is triggered randomly during the base game.
If and when it does, you’ll have a shot at winning the Major Jackpot. This is guaranteed to be worth at least £500,000. Even the Maxi is worth at least £25,000. There’s also the unique free spins round. Here, you get to play a variation of the old mobile phone game, Snake! If you haven’t played this slot yet then it’s worth checking out the best slots bonuses UK players can use and giving it a few spins.
Best Megaways Slots
Bonanza Megaways
Bonanza is, for many, the game that changed the slots world forever. It was the first Megaways game, from Big Time Gaming (BTG), to go mainstream. This six-reel video slot offers up to 117,649 ways to win on each spin. The base game has the capability of producing massive hits. Although, it’s the free spins bonus where most of the win potential is found.
Triggered by landing 4+ scatter symbols in view, the bonus is an unlimited free spins round with an unlimited win multiplier that increases with each cascading win! The frantic action makes this one of the best online slot games to win in the UK.
Diamond Mine
Diamond Mine, from Blueprint Gaming, was another early Megaways success – and it’s actually pretty similar to Bonanza. The core difference, however, is the less volatile maths model it’s designed around.
The structure remains the same. You’re far more likely to trigger the bonus round naturally. This came as welcome news to punters who were frustrated with Bonanza! Diamond Mine offers a maximum win potential of more than 10,000x, and you’ll find it at most UK slots sites!
White Rabbit
Following the success of Bonanza, BTG didn’t wait long to release another blockbuster slot – White Rabbit Megaways. Unlike Bonanza, however, this five-reel game offers up to 248,832 ways to win – and it’s also playable from just 10p per spin, making it suitable for low rollers.
Random reel modifiers in the base game can add up wild multipliers to the reels. The free spins bonus features expanding reels that, when reaching 12 high, award more free spins! It’s an exciting slot and with an RTP of 97.77%, you can often enjoy lengthy playing sessions, too!
Rasputin Megaways
Rasputin Megaways is one of Big Time Gaming’s latest releases. This mystical six-reel slot offers up to 117,649 ways to win in the base game. Wild Rasputin symbols reveal a number corresponding to how many symbols are added to that reel.
If you can land three or more scatter symbols in view, you’ll trigger the bonus. In this bonus you get to choose from two free spin modes: Extending Reels which expands reels up to 12 rows high, or Ecstasy and Fire with an unlimited progressive multiplier. Rasputing Megaways offers a max win of over 60,000x, making it a must-play for fans of volatile slots!
Extra Chilli Megaways
Available at most of the best slots sites UK players can join, Extra Chilli is yet another hit BTG slot. It’s an unofficial sequel to Bonanza, and the game developer’s signature Megaways mechanic makes an appearance once more.
If you can land three or four scatter symbols during the base game, you’ll win eight or 12 free spins – but now, you can try to gamble your way up to 24 spins! Big Time Gaming’s FeatureDrop mechanic is also in play here, so if you play for long enough, you could trigger the free spins regardless of how your session has gone. It’s widely considered one of the best slots games UK players can play.
How To Maximise Your Chances Of Winning On Slots
While slots are completely random, there are some slot tips you can follow to improve your chances of winning and get more enjoyment out of your gambling sessions:
- Choose slot games online in the UK with high RTPs. This slightly improves your chances of a winning playing session. Generally, you should look for games with RTPs of 96% or higher.
- Manage your bankroll. When gambling online, never bet more than you can afford to lose. See every deposit as a ‘loss’, and don’t try to win back money you’ve already lost.
- Claim bonuses. Don’t be afraid to take bonuses and free spins promotions. Doing so can give you more chances to win without risking your own money. Just be sure to read the terms and conditions before playing so you know what’s allowed and what’s not.
- Try new games and providers. While it’s easy to get hung up on a few games – or a specific provider – try to give new releases a try from time to time. This will introduce you to new titles, and, potentially, new providers.
Remember, even with these tips, the best online slot games in the UK are still gambling games based on chance. You will lose in the long run – but with a bit of luck, it is possible to hit a winning session every now and then!
