![\"Best](\"https:\/\/www.bonusfinder.co.uk\/images\/Best-Slots-Sites.png\")
<\/p>\nThe top UK slots sites have a big number of casino games and welcome bonus offers you can use on slots!<\/p>\n<\/div>\n
Best for Game Variety<\/h3>\n
BetVictor has over 1,500 slot games, easy navigation and a great welcome bonus, making it arguably the best slot site. However, the BetVictor welcome offer<\/a> is geared more towards table games but they still offer some bonus spins! BetVictor’s strength is definitely their wide variety of UK online slots and we personally love the site a lot.<\/p>\n Casushi Casino<\/a> might look a little old-fashioned, but the selection of top slot games is unbeatable. The slot site has over 2,000 games and offers bonus spins to new customers. We are deducting some points due to the lack of subcategories which makes navigating the slots a little difficult.<\/p>\n NetBet might appear to be more focused on sports betting, but it stands head and shoulders above many sites with over 1,500 UK online slots. What we particularly love about NetBet is their navigation menu; you can find the most popular slot themes on their own tabs. Only NetBet free spins no deposit<\/a> could sweeten this online slots site! <\/p>\n Mr Vegas has a massive selection of jackpot slots with numerous different themes and features. It is hands down the best slot site for progressive jackpot slots as several jackpots can rise to millions at the same time! The site also has lots of daily jackpots, so all types of players should be satisfied with Mr Vegas slots<\/a>.<\/p>\n Unibet is our second pick for progressive jackpots due to their 200+ catalogue. Where they stand out is the Daily Jackpots category: the slot site has 180 progressive jackpots that are won every day! Unibet casino bonus<\/a> is also applicable to many jackpot slots, making the online casino a great option for you.<\/p>\n BetMGM is one of the new UK slots sites but already in the top-3 for jackpot slot games. In addition to many of our favorites, the MGM Casino UK<\/a> has several exclusive casino slots you won’t find anywhere else. BetMGM’s bonus might not be the best, but several online slot sites have much worse libraries so take a look at this one when you want to play online slots.<\/p>\n PartyCasino offers over 100 Megaways slots, including favourites like the Dog House Megaways and newer games such as Neptune’s Fortune Megaways. Party Casino is often overlooked among UK slot sites but there’s plenty to like about it, including the Party Casino free spins<\/a> bonus.<\/p>\n Regal Wins promo code<\/a> REGAL nets you some free spins and a deposit bonus, the latter of which you can spend on some of their Megaways slots! Regal Wins is one of the better looking UK slots sites and has loads of other games you can play in addition to Megaways video slots.<\/p>\n Betway has a really fantastic selection of Megaways, although slightly fewer games than the other two. What made us add it to the less are the Betway 125 free spins<\/a> and the variety of Megaways titles; few sites can match the number of different themes you can find on Betway.<\/p>\n bet365 has a terrific free spins bonus for online slots UK, as you can spend 100 free spins on several different video slots. The bet365 casino bonus<\/a> requires just a \u00a310 deposit and there are no wagering requirements! bet365 is also one of the top slot sites in the UK with plenty of fun and new slots to test.<\/p>\n Yeti Casino<\/a> awards you 23 spins on registration, and another 77 after your first \u00a310 deposit. You also get a refund bonus if you end up losing your deposit during your gaming session! Although the wagering requirements are on the higher side for the free spins, you can play one of the most popular slots ever, Book of Dead.<\/p>\n Quatro Casino<\/a> welcome bonus includes up to 700 free spins, which is a massive deal! You do have to make a big deposit, but the overall value of the bonus money is excellent. The Casino Rewards brand has a great online slot selection and plenty of other online casino games, too.<\/p>\n In addition to having a ton of the best slot games, we expect the UK online slots sites we recommend to excel in many areas. We rate online casino sites based on transparency, fairness and legality in addition to online casino game quality and volume, payout speed, customer support, and slots bonuses. <\/p>\n The BonusFinder team has decades of collective experience in online gambling and each slot site review is based on our expertise and players’ comments. Our reviews are fair and transparent, although we will collect a small fee for each player who signs up through our website to play online slots. <\/p>\n Below are more details on our review processes:<\/p>\n First and foremost, we only recommend and list slot sites which are licensed and regulated by the UK Gambling Commission. This is crucial as these sites are bound to follow all regulations to take care of their customers’ funds and personal details, in addition to running fair games.<\/p>\n We also accept online slot sites to our websites if they have a clear and transparent casino bonus policy. Each casino bonus on BonusFinder has been tested to make sure there’s no “catch” that makes it impossible to wager through, for example. You can always trust that we have your interests at heart.<\/p>\n As mentioned above, each online casino listed here is licensed by the UKGC. This means the online slot site follows strict standards for player protection, fairness, and financial security. You can find the UKGC stamps on each website to indicate they have passed the inspection and received a license. If you only play on slots sites recommended by BonusFinder, you can be sure that they are legal.<\/p>\n When recommending online casinos for specific games, we naturally take a look at their casino games and the variety they offer. When it comes to the best slot sites in the UK, we are very fortunate since most operators have hundreds if not thousands of games to choose from.<\/p>\n The best UK slot sites have a great selection of different slots, in addition to some other games to satisfy all kinds of players. The best sites also run slot tournaments and other promotions slot players can participate in to enhance their gaming experience.<\/p>\n Naturally welcome bonuses are an important factor when choosing among online slots sites. There are a ton of bonus spins and deposit offers to choose from, so it might be difficult to pick the best offer for you.<\/p>\n The best online slot sites listed here have great bonuses you can use on slot games. We consider factors like initial deposit and wagering requirements when we add new offers to our list, so you can be certain that different aspects of the offers are reasonable for all UK slots players.<\/p>\n We seek out the best slot sites with convenient payment options like eWallets and pay by phone. Depositing funds is simple on all sites and you can always withdraw your deposits whenever you feel like it. Minimum and maximum deposit and withdrawal limits are also important to us since they are important to you.<\/p>\n Registering a new account on any slot site is really simple and each has roughly the same steps listed below. You can only sign up on an online slots site once to get bonus money, but you can sign up for several different sites within the same group, for example.<\/p>\n Once you have made your choice of the best slot sites, it’s time to start playing! If you are new to casino games, here’s a short guide on slot games’ main features.<\/p>\n On each online slot site, you can find hundreds of slot games which might get overwhelming if you don’t know yet what you like to play the most. Below we’ve listed the best online slots you can find on any online slots site! You can also check out our list of the top 10 best slot games<\/a> or test demo slots UK<\/a> if you want to play free online slots.<\/p>\n Did you know that the first slot machine was the Liberty Bell designed by car mechanic Charles Fey all the way back in 1894? The original ‘One-Armed Bandit’ had three reels which were spun by pulling a mechanical lever on the side, and paid out a jackpot of 50 cents. The classic slots you will find in today’s online slots sites have come on a bit since then, but they still hark back to the simplicity of the first designs.\u00a0<\/p>\n These online slots games have retro styles, basic graphics, and Vegas-like sounds. Playing classic online slots can be a calmer and more relaxing experience than games bursting with bonus features to keep track of. Classic games also have some of the highest RTPs, making them the perfect choice when you need to play through a wagering requirement.\u00a0<\/p>\n Due to its simplicity, player favourite Starburst<\/strong> can be considered a classic slot. Many online casinos give free spins bonuses for Starburst because this is a great game for first-timers and has an enduring appeal with more experienced slots players.<\/p>\n Megaways casino games shook up the online gambling world when Big Time Gaming first released Bonanza in 2016. Nowadays, you can find Megaways versions of all the most popular slots and almost any theme imaginable from Ancient Egypt to the furthest reaches of the future.\u00a0<\/p>\n Megaways slots are so appealing because they have many more ways to win than your standard slot. They have 6 reels with 2-8 symbols showing on every spin creating up to a maximum of 117,649 paylines.<\/p>\n Our favourite Megaways casino<\/a> is definitely Party Casino who have a dazzling selection of over 100 Megaways slots, including all the classics and some rarities like Shamrock Holmes which combines our favourite consulting detective with the magic of the Emerald Isle.\u00a0<\/p>\n You could argue that slingo isn’t really an online slot game, since it blends both slots and bingo. The game type is still quite new online and most slots sites don’t have as many slingo games as they do slots, but the number of slingo sites<\/a> is increasing steadily.<\/p>\n The game is played on a 5×5 bingo-style grid and a slot reel below it, and the goal is to get numbers on the reels which also appear on the grid. If you get five numbers next to each other on the grid, you get a slingo! <\/p>\n The game might seem confusing but the game play is surprisingly simple once you start. In addition, many slots sites have plenty of tournaments where you can end up winning some extra prizes if you do well.<\/p>\n Many online slots will boast of big jackpots, but it is the progressive jackpot slots that have the capacity for truly life-changing wins. Standard jackpots are set by the casino or developer and do not change. Progressive jackpots, on the other hand, keep increasing the more times the game is played, until one lucky winner scoops up the prize.\u00a0<\/p>\n The biggest progressive jackpot slots are hosted by the online casino game developer, and the jackpot will be shared by several different games and different casinos. This huge player base allows the jackpots to grow into six-figure sums, as the jackpot takes a small cut from each spin made on any of the games included.\u00a0<\/p>\n The biggest wins from progressive jackpots have come from WowPot and Mega Moolah series, but there are a lot of excellent jackpot slots<\/a> to choose from on any slot site.<\/p>\n Daily jackpots are guaranteed to pay out every day, so there is one lucky winner every day! These are sometimes called ‘Daily Drop’, ‘Must Drop’, ‘Must Go’, or ‘Must Win’ jackpots, and while the winnings aren’t as big as on the ones that aren’t won daily, these can still offer some decent sums.<\/p>\n Red Tiger first introduced the Must Drop concept back in 2016 when Paddy Power approached them to ask for a feature that would add excitement to slot players during the UEFA Euro Cup. Thus the Must Drop was born, as a slots jackpot that had to be to be won by the end of the game. The closer the time got to the full 90 minutes, the greater the chance of winning, and the higher the level of excitement!\u00a0<\/p>\n Hopefully you’re not too overwhelmed, since now we will discuss themes you can see on the best online slots! Themes are usually important to players since you can to play something you enjoy. For example, if you really dislike vampire themes, you’ll know to avoid Blood Suckers slots. Each online slots site has a ton of different themes, here are just a few of our favorites:<\/p>\n Slot tournaments are one of the main promotions online slot sites provide to existing customers. Usually the site has marked certain slot games as a part of the tournament and players participate by playing these games with a certain amount of money.<\/p>\n If you want to take part in slot tournaments, make sure to check the casino websites for information on them: when they start, what you need to do to participate, and how often can you play in order to win something.<\/p>\n There are a couple of different types of slots tournaments: One Hit awards the highest single win over a specified number of spins, while Fair Change divides the wins by stake, giving everyone the same chance to win. <\/p>\n Since online slots come in many forms, there are naturally plenty of developers who make them. The best slot sites have a mix of casino games from many online casino game providers; below we’ve gathered the top providers who make out favourite slot games.<\/p>\n NetEnt is a Swedish company established in 1996. It has given us some of British players’ best liked slots, including Starburst, Gonzo’s Quest and Finn and the Swirly Spin. NetEnt casinos<\/a> also have many slots tied in to popular TV & movie franchises, including Narcos, Knight Rider, and Gordon Ramsey’s Hell’s Kitchen.\u00a0\u00a0<\/p>\n Microgaming is one of the biggest slot developers in the world, both in terms of the number of casinos that have their games and the sheer quantity of titles that they have created. They have so many games to choose from that there are a number of Microgaming casinos<\/a> who don’t see the need to sign-up with any other game providers, as Microgaming have all bases covered.\u00a0\u00a0<\/p>\n Microgaming leads the pack when it comes to signing lucrative deals with popular franchises, and has made slots versions of fan favourites such as Game of Thrones, Battlestar Galactica and Jurassic Park.\u00a0<\/p>\n Although you won’t find Yggdrasil Gaming’s slots in as many casinos as the bigger studios, it is well worth hunting them down. Yggdrasil are committed to creating a higher quality gaming experience for slot players, and their graphics are second to none. Check out Vikings Go Berserk, and Blood Moon Wilds as two of their top titles.\u00a0<\/p>\n Playtech are probably best known for their Age of The Gods games, which draw on Greek mythology and multiple bonus features to create a lasting legacy.<\/p>\n There are many variants of the basic game to choose from, but our favourites are Age of the Gods – Goddess of Wisdom and their recent foray into the Nordic legend, Age of the Gods Norse – Gods and Giants. You will normally find all of these and more at the best Playtech casinos<\/a>.\u00a0\u00a0<\/p>\n The most famous Play’n GO game is the monumental success Book of Dead. Players just can’t get enough of the slot’s protagonist Rich Wilde, and he has taken on a life of his own and spawned many sequels.<\/p>\n What really makes Play’n Go casino<\/a> games stand out is the exciting stories that unfold as you play, and a range of bonus rounds and features that are lacking in many competitors’ lacklustre copies of these games.\u00a0<\/p>\n IGT makes both online slots and real world live casino slots that you can find all over the world in brick-and-mortar casinos. They have created a range of branded video slots, including Transformers, Harley Davidson and Ghostbusters, and also have the most cat-themed online slots of any game provider we have reviewed, including Kitty Glitter and Prowling Panther.\u00a0<\/p>\n Red Tiger slots are some of the most sought after games in 2024. One of the reasons is their epic progressive jackpots, and their Daily Drops. The main reason though is the quality of their games which are chockablock with surprises and bonus features. Their most popular games include Piggy Riches Megaways, Narcos Mexico and Primate King, but one of our favourites is the highly volatile Reptizillion Power Reels!\u00a0<\/p>\n Bristol based studio Red7 Mobile were renowned for making slots that worked perfectly on hand-held devices since the dawn of smartphones in the 2010s. They were acquired by gambling industry giants Scientific Games in 2017. You can still find a number of Red7 Slots<\/a> at some of the biggest UK slot sites.\u00a0\u00a0<\/p>\n No Limit City is an independent games studio based in Sweden, that tries to push the boundaries of what slot games can be. You will not find any cute leprechauns or relaxing fishing games in the No Limit catalogue, but rather angry roadkill or graffitied public toilets.<\/p>\nBest for Progressive Jackpots<\/h3>\n

Online Slot Features<\/h2>\n
\n
The base game refers to the normal gameplay of the slot with the standard reels, meaning without any extra features. Normally you just spin the reels in the base game and you can adjust your bet after each spin.<\/li>\n
Bonus rounds and features are triggered when certain events happen in the base game, such as landing three scatters or a bonus symbol on the reels. Bonus features include expanding symbols, free spins, extra games where you choose among different options, and bigger multipliers per spin.<\/li>\n
Return-to-player percentage indicates the average payout of the slot over long-term play. Slots with RTP of 97% or over are considered high RTP and therefore better options, but it doesn’t matter that much as in the long term, you will lose more than you win no matter what slot you play.<\/li>\n
Volatility indicates how often a slot game pays out and whether the payouts are big or small. Low volatility slots pay out frequently but a little at a time, while high volatility slots are the opposite of that.<\/li>\n
Symbols are the icons that appear on the reels and indicate your winnings. Usually some symbols in a game are classic slot symbols like cherries, diamonds and card symbols and the rest fit the theme better. You can find all symbols, their value, and which ones include bonus features from the game info.<\/li>\n
Paylines determine how much you win per spin, addition to the number of symbols you land. They run usually from left to right and the total number can vary per game, but usually there are between 5 and 20. If you land enough of the same symbols on a payline, you win. Some slots let you adjust the number of paylines you bet on while others make you bet on all of them on every spin.<\/li>\n<\/ul>\nTypes of Online Slots<\/h2>\n
