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 March At Leo Vegas, UK players can get up to 50 free spins on Big Bass Splash 25 spins for your first and second deposits with no wagering requirements.

They also offer regular free spins promotions and competitions for online slots players. The earliest online slots in the UK were quite straightforward, typically featuring five reels with three rows.

Fast forward almost two decades, and today's players are presented with an entirely new generation of casino slots, offering various formats and enticing features.

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.

Must Drop Jackpot slots feature a jackpot prize that must be won before it hits £1,, while Daily Drop Jackpots are guaranteed to drop before GMT each day. Meanwhile, Mega Drop Jackpot Slots are progressive jackpots which will drop before they reach a maximum payout value, rather than grow indefinitely.

Slingo, a blend of 'Slots' and 'Bingo,' provides a distinctive gaming experience where players complete a bingo-style grid with numbers spun on a slot reel. The goal is to match numbers to complete winning lines 'slingos' and advance up the prize ladder toward a full-house and the top prize.

Nowadays, game 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 slots, with titles like Wanted Dead or A Wild , Cubes , Itero and Chaos Crew.

In these games, it truly is an all-or-nothing experience, emphasising a high-risk, high-reward style of gameplay. NetEnt were the first to break the k barrier with Dead or Alive 2, offering a maximum pay-out of ,x your stake, later surpassing it with the release of Starburst XXXtreme at ,x.

Such wins are among the reasons why Nolimit City slots have secured a place in the favourite slots lists of many players. The dream of landing a life-changing fortune is on offer with progressive jackpot slots, with each bet contributing a small portion to a continually growing jackpot.

These progressive online slot pools keep on increasing until one player strikes it rich. The biggest are the WowPot and Mega Moolah series of jackpot slots, but below our team of experts have listed all of the big online slots jackpots currently up for grabs, along with the best UK slot sites where you can try your luck for each.

Microgaming launched the original safari-themed Mega Moolah progressive jackpot slot back in to much acclaim. Since then, the Mega Moolah series has been expanded to include a variety of titles, such as Fortunium Gold , Mega Moolah Goddess and Absolootly Mad - the latter of which holds the record for the largest Mega Moolah jackpot ever won £ That monster win came just two weeks after a WowPot jackpot of £ But a world-record slots jackpot of £33 million was won in December on the appropriately named WowPot slot game Wheel of Wishes.

Whilst the aforementioned slots all contribute into shared jackpot pools, the following four slots are stand-alone games, each boasting its own progressive jackpot:.

Below we've categorised the most popular themes and shared our personal favourites from each. The world of animal-themed online slots can transport you to the North American plains, Amazonian jungles, the depths of the ocean, or simply feature your favourite pets. Part of the Big Bass series from Pragmatic Play, this slot offers engaging gameplay with clean artwork.

The free spin bonus round features a ladder trail with extra spins and an increasing multiplier for each unlocked level. Another great slot from Pragmatic Play and one of the earliest to feature the Megaways game mechanic. The free spin bonus round presents a choice between Sticky Wilds or Raining Wilds, both with the potential for mega payouts.

Blueprint Gaming and Microgaming lead the way for movie slots and this category could easily include another six or so exceptional games, but we've tasked Ana Dimitrijevic and the team with whittling it down to the Gambling.

com top three. Whether or not you're a fan of the Spielberg blockbusters, Microgaming's Jurassic Park slot is a real treat to play. Land three Amber scatters to choose between five exciting bonus rounds and look out for the T-Rex symbol, which triggers Alert Mode, adding 35 wilds to the reels for the next six spins.

Join the lovable yet wholly inappropriate Ted from the film in a journey of debauchery, full of references to sex, drugs and alcohol. Expect randomly-awarded bonuses and trigger one of six bonus features with three scatters. Our favourite is the Bar Crawl Bonus, while the Ted Big Money Bonus offers the chance for the biggest win in this Blueprint slot.

There are also numerous excellent slots based on popular TV shows, which offer fans an interactive way to immerse themselves in their favourite characters and themes. This Microgaming slot really captures the essence of the legendary HBO series, including its stirring soundtrack and actual clips from the Westeros saga.

Unusually, you can choose from four free spin features and even have the opportunity to gamble your winnings. No other game provider excels at creating adult cartoon-themed slots more than Blueprint; it's truly their forte.

The mechanic of this game may seem familiar, but it is more than just a reskinned slot. You get to choose from four fantastic bonus features: Pickle Rick Spins, Federation Wild Spins, Vindicator Spins and Mystery Spins, all with a potential maximum win of 50,x.

While Pragmatic Play aren't typically known for licensed slots, they've nailed it with the Peaky Blinders slot. With gritty character voice overs and random bonus features like The Shelby Betting Shop and By Order of the Peaky Blinders, this game perfectly recreates the atmosphere of the beloved West Midlands gangster series.

Such is its popularity, for some players there simply are no other types of online slots. Trigger the free spins bonus round to receive a 3x multiplier with the possibility of unlimited retriggers, while landing nine scatters wins you the jackpot. Triggering the Cash Collect feature on reel 5 can lead to winning all cash prizes or activating the free spins bonus round.

Plus, there are four Cash Collect fixed jackpots available, determined based on a multiplier of your stake. There are probably more online slots based around mythology than any other genre - players will never tire of these mythological slots and game providers regularly release new versions.

I always like it when reel symbols tumble rather than spin, while winning combinations are paid then replaced by new symbols for additional wins. Although four scatters are required to trigger the bonus round, you are rewarded with a generous 15 free spins to start.

The clean graphics, smooth animation and eerie sound effects result in a truly immersive slot. New releases of Ancient Egyptian themed slots often share common characteristics, including expanding reels, the potential to retrigger bonuses and opportunities to gamble each win.

Skillfully remastered by Novomatic, Book of Ra Deluxe continues to entertain players, more than 15 years after its debut in land-based casinos. It is still considered by many to be one of the best slot games on the market. But what sets 'Legacy of Dead' apart are its distinctive themes and advanced graphics, making it another favourite with slot players.

Unusually for an online slot, the maximum win of 5,x can be achieved through the base game and not just the bonus round. This is largely thanks to the multipliers that increase with each win, potentially reaching up to x. The simple, yet charming appeal of clean graphics and an easy to achieve free spins bonus round makes this NetEnt classic a joy to play.

Although not at the top of our favourite themes for the slots team at Gambling. com, there are a few excellently executed pirate themed slots bobbing around the lobby of many online slot sites in the UK. It gives you the chance to infinitely retrigger more free spins during the bonus round, complemented by a 4x multiplier.

Whilst those are the most common themes for online slots, UK players have endless options - from Dinosaurs to Dragons, Sci-Fi to Sweets or Vampires to Vikings. No matter your preference, there is almost certainly an online slot themed around it.

Launched back in , this exquisitely simple slot from NetEnt, is without doubt the most played online slot ever. These wilds remain sticky while triggering one or two more respins, a unique mechanic that has contributed to its enduring popularity.

Themed around the Yukon trail, Bonanza was responsible for a flurry of similar themed slots - all of which were literally trying to jump on the gold rush bandwagon. Expertly crafted by Blueprint Gaming, this Stone Age-themed slot also boasts a high RTP of Pragmatic Play built on the success of Sweet Bonanza with this candy and gummy bear-themed slot, featuring an innovative 'Cluster Pays' mechanic.

Each win not only clears the screen but also increases the multiplier up to x and the bonus round awards up to 30 free spins, with unlimited retriggers available. Blending Steampunk and Wild West themes, Relax Gaming's hit slot has been so successful that it has spawned two sequels, with all three instalments offering a huge maximum win potential of up to 50,x your stake.

This slot is packed with a huge array of bonus features including Sniper, Collector, Collector-Payer, Necromancer, Shapeshifter, Absorber and Tommy Gun.

Whilst the basic concept of most online slots is the same, many offer a unique mix of game mechanics and features that impact gameplay and potential winnings. The base game is usually straightforward and you just need to choose your bet size and start spinning. The bet size, also known as the spin value, allows you to customise your play and tailor wagers to suit your budget.

The way it is calculated can vary for different slot games, but typically includes the following elements:. Most online slots require a minimum of three matching symbols to create a win, although some slots pay for matching just two of the highest-value symbols. Traditionally, winning combinations are formed by matching symbols on adjacent reels, with the default being left to right although innovation has brought us a number of interesting payout structures, including:.

The bonus round is usually triggered when three or more Scatter symbols are landed, which then awards free spins along with enhanced features and multipliers, such as:.

Top-tier software providers have had to up their game in recent years, facing ever-increasing competition from smaller studios eager to push the boundaries of innovation. This has led to an evolution in the online slot experience for UK players, who have access to an unprecedented selection of online slot software, each aiming to deliver a distinct and memorable gaming experience.

Below we have listed the current top online slot game software providers, if you want to dig even deeper check out the Gambling. com guide for leading gaming software providers in the UK:.

With beautifully crafted games like The Dog House, Gates of Olympus and Buffalo King, Pragmatic Play treads a fine line between playability and volatility. Their online slots, while exciting and immersive, can be bankroll-hungry offering lower RTPs. Pioneering the Megaways game mechanic, Big Time Gaming has revolutionised slot development over the last decade, with innovative titles like Bonanza Megaways and Extra Chilli Megaways setting new standards in the industry.

This mechanic has now been licensed to other top software providers, rejuvenating many classic slots with a fresh twist.

Once the leading slots provider, Microgaming still boasts a vast library of top titles, including Immortal Romance, Game of Thrones, Lara Croft and Jurassic World, along with other familiar licensed slots.

Notably, the two biggest progressive jackpots series WowPot and Mega Moolah are both exclusive to Microgaming slots. As one of the early pioneers of online gaming, NetEnt has set numerous records and their iconic Starburst remains the most popular online slot to date.

Here are the top 15 best paying slot games in the UK ranked by their advertised RTP Return to Player percentage. The RTP percentage is a factor to consider when selecting which online slots to play.
