UK top slots

BonusFinder have listed the best places to play slots online in the UK.

✨ New Online Slots UK

Since the first internet casinos started in the 1990s, online slot games have become more and more popular, and there is no end to this trend in sight. In 2022 you can find thousands of slot games at online casinos, dedicated slots sites, betting sites, bookmakers, and Bingo sites. The UK market is highly competitive, and dozens of new sites launch every single month.

With so much choice it can be difficult to work out where is the best to play, but that’s where BonusFinder steps in. We have tried and tested all the UK sites on your behalf, and will only ever recommend the most safe and trusted slots sites for you to play at.

Every slot site on our list has a UK Gambling Commission (UKGC) licence, and so has met the necessary security standards and proven that their games are fair. We make sure that their online slot bonuses, and free spins deals, are above board and have player-friendly T&Cs. We also check that the sites work well on both desktop and mobile, so that you will get the best gaming experience no matter what device you prefer to play on.

Latest Slots Sites

In August 2022 our top pick from all the newest places to play online slots is Jammy Monkey, which burst onto the scene in late 2021. They have a free bonus on registration for all new players where you can get up to £10 to use on any slots on their site. If you are interested in other new slots sites we have reviewed all the newest online casinos and found the best welcome bonuses from new slots sites.

Good Slot Sites for New Players

If you are new to playing slots online for real money it can be difficult to know what to look for in a slots site. You might want to start out with a no deposit bonus to dip your toes in the water, but these often come with high wagering requirements that you need to complete before you can withdraw any of your free spins winnings.

We recommend that new slots players start with 888 Casino, as their bonus on sign-up gives you 88 free spins with only 1x wagering on winnings. This low playthrough requirement means that you have a much better chance of getting to keep what you win, and 888 Casino has such a large selection of slots that you are almost guaranteed to find a game to suit your fancy.

Jammy Monkey is a new slots site that is driving British players bananas with their unique games and generous no deposit bonus.

🎁 Online Slots Bonuses and Free Spins

British players can get a broad range of bonuses and welcome offers when they sign-up at a new online slots site. Although different sites may vary slightly in their selection of games, the biggest difference between them really just comes down to aesthetics as most use the same software, offer the same payment options, and nowadays all work well on mobile. Player bonuses, and other perks, are the main way that a casino or slot site can stand out from the crowd.

When you claim a slots welcome bonus you can get free cash to spend on the site, or free spins for the most popular games. This lets you play slots for real money without risking a penny of your own.

Slots bonuses do come with Terms & Conditions attached, and you will need to jump through a few hoops before you can withdraw your winnings as cold hard cash! When you claim bonus money it comes with a wagering requirement, which is the number of times you must play through the value of the bonus before your winnings will be transferred into a cash balance that you can withdraw. The most common wagering requirement is 35x for a first deposit bonus, but no deposit slots bonuses can come with anywhere up to 200x wagering.

If you claim free spins bonuses the wagering requirement may be on the value of the spins, or on any winnings from the free spins. Some slots sites will give you no wagering free spins, or real money free spins, where any winnings will be credited to your cash balance without the need to make a wager. Some casinos will only let you continue using your bonus balance or free spins once you have played through your cash.

Other things to check in the T&Cs include the length of time your bonus is valid for, any games that are restricted from playing with bonus funds or that do not contribute towards the wagering, and whether any payment methods are excluded from first deposit slots bonuses. You may also be limited to a maximum stake per spin, or a cap on winnings, and free spins are normally locked to one or two specific games on the slots site.

Slots sites UK

888 Casino, Mr Green and Party Casino all have great bonuses for British slots players.

💰 Best No Deposit Slot Sites

Many online slots sites will give players a sign-up bonus with no deposit needed just for entering their details and creating an account. These offers are great as you receive the bonus money or free spins on registration without needing to spend a penny.

In August 2022 these are the best UK no-deposit bonuses for free spins:

  1. 100 free spins no wagering: Pokerstars Casino
  2. 88 low wagering free spins: 888 Casino
  3. 50 free spins no deposit: Mr Green Casino
  4. up to 250 free spins on registration: mFortune
  5. 20 free Book of Dead spins: NetBet
  6. 55 Starburst free spins: Casino Cruise

Free spins are normally locked to specific games, so if you want to try your hand at a variety of different slots you should claim no-deposit casino funds instead. Some slots sites prefer to give you introductory cash funds to let you explore their site more thoroughly and choose which games you want to play.

The best free money no deposit slots bonuses are:

  1. up to £5 free: Bonus Boss
  2. Free £15 registration bonus: William Hill
  3. up to £10 free: Jammy Monkey
  4. £5 free on sign-up: Jazzy Spins
  5. up to £10 free: Pocket Win
no deposit slots bonus

British slots sites like mFortune, Pokerstars Casino and Bonus Boss will give you an introductory bonus to start playing real money slots for free when you sign-up for an account.

Best Low Wagering Slots Bonuses

The best bonuses for players are those that come with no-wagering or low-wagering, as these will let you keep what you win. These slot sites let you withdraw your winnings as real money without having to go through lengthy playthrough requirements. It is rare to find a no deposit no wagering bonus, but you can unlock great deals by making a small £5 or £10 deposit.

These are the best free spin slot bonuses with no wagering:

🏆 Rank 🎰 Slots site 🍒 No wager free spins 💰 Minimum deposit
1 Betfred 100 free spins £10
2 Mr Q Casino 75 Wager-Free Spins £20
3 Play OJO Casino 90 Free spins EXCLUSIVE OFFER £10
5 Voodoo Dreams 50 bonus spins £20
6 Video Slots 100 bonus Starburst spins £10
7 NYspins 50 bonus spins £20
8 888 Casino 88 spins with 1x wagering no deposit

The BonusFinder experts consider any requirement under 30x playthrough to be low wagering. Remember to check that the multiplier only applies to your free spins winnings or bonus funds – if it applies to the deposit + bonus then you will need to clear twice as much before you can cash out.

The top low-wagering slots sites are:

🏆 Rank 🎰 Slots site 🎁 Slots bonus 💫 Wagering
1 888 Casino 88 free spins no deposit 1x free spins winnings
2 Grosvenor Casino up to £30 5x - 10x bonus funds
3 Casino.com 200 bonus spins after 1st deposit 20x free spins winnings
4 Party Casino 50 Starburst bonus spins 10x winnings
5 Slot Crazy 100 bonus spins 30x winnings

Before you start to play check if any games are excluded from the wagering requirement. Sometimes money spent on certain games will not contribute towards clearing the bonus, or will only count 10% – 50%. Most slots count as a 100% contribution, but some jackpot games may be less, and live casino or table games are normally not included as the RTP is much higher.

This is our rundown of the top online slots to play in the UK for real money in August 2022:

🎰 Playing Free Slots Online

There are many different types of online slots to choose from, and this can be confusing for both new and experienced players. The online gambling world is very fast moving, and game developers are constantly coming up with exciting new features, or innovative gameplay styles to try to attract the most players. Here is a quick rundown of the most common slot game types you will find at most online casinos:

Classic Slots

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.

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.
Due to its simplicity, player favourite Starburst 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.

Video Slots

All of the games you will find at an online casino are technically video slots, as the reels are electronic rather than mechanical. However, when we talk about video slots we are normally talking about games that have more excitement than the classic slot. These games tend to include lots of extra features such as multiple pay lines, slots bonus rounds, and even mini-games.

Video slots have great graphics, thumping soundtracks and are more immersive to play. Many also feature a longer storyline or narrative, and familiar or iconic characters. Some of the most popular video slots for UK players include Gonzo’s Quest, Book of Dead and Dead or Alive.

Megaways Casino Slots

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.

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 117649 paylines. Our favourite Megaways Casino 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.

Progressive Jackpot Slots

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.

The biggest progressive jackpot slots are hosted by the 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.

The most popular progressive jackpot slot in the UK is, without a doubt, Mega Moolah. If you want to see what all the fuss is about then head over to Zodiac Casino and get 80 Mega Moolah spins for just £1.

Daily Drops and Hourly Jackpots

One of the latest developments in online slots is the introduction of limited time jackpots such as the Red Tiger Hourly Jackpot you can find at 888 Casino.

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 slots 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 time got to the full 90 minutes, the greater the chance of winning, and the higher the level of excitement!

Online Slots Tournaments

Slots tournaments are a pretty new way to play, and are currently only available on some slots sites. These competitions pitch players against each other to top the leaderboard whilst playing a certain slot. The bigger tournaments can have prizes including 5* holidays or must-have gadgets, but most will give smaller rewards like free spins or a few quid.

Taking part in a tournament is fun, and the competition brings a sense of community amongst online players, as you can see how everyone else is doing and compare your progress.

In 2022 more and more casinos are starting to host slot game tournaments. Mr Green Casino is one of the biggest and best with their Reel Thrill Slots Tournament. This is played on the Reel Thrill games, and the leaderboard resets every 15 minutes. Your score is calculated as a proportion of the profit from the 20 spins you make in this round, and the top 5 leaders are granted a real cash prize. Unibet, 32Red, and William Hill are other slots sites that run their own form of tournament.

Free Play

Some slot sites and casinos will let you “try before you buy” and play games in demo mode. This is a great way to understand how a slot works before you play, but due to UK Gambling Commission regulations, you need to be registered at the site and prove your age to be able to play for free.

Party casino megaways slots

Party Casino is the top site for playing Megaways slots in August 2022.

🎮 Online Slot Game Developers

With a few notable exceptions, most UK casinos will feature a range of slots by several different game providers. There are hundreds of large and small studios creating new and exciting slots and casino games, and different game-makers will specialise in certain features or gameplay styles. Many larger studios have bought the rights to make slots for a TV or film franchise, or their own game characters will be so popular that they have become a brand of their own.

Here are a few of our favourite game developers in 2022:

  • Microgaming
  • NetEnt
  • Yggdrasil Gaming
  • Playtech
  • Play’n GO
  • IGT
  • Red Tiger

Microgaming

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 who don’t see the need to sign-up with any other game providers, as Microgaming have all bases covered.

Mega Moolah is far and away the most popular Microgaming Slot, as players go wild for its exciting features and huge progressive jackpot. The Guinness World Record for largest online slot win is held by a British man who walked away with a whopping £13,209,300 after hitting the Mega Moolah jackpot on 6 October 2015.

Microgaming also lead the pack when it comes to signing lucrative deals with popular franchises, and have made slots versions of fan favourites such as Game of Thrones, Battlestar Galactica, and Jurassic Park.

NetEnt

NetEnt is a Swedish company that has given us some of British player’s most wanted slots, including Starburst, Gonzo’s Quest, and Finn and the Swirly Spin. NetEnt also have the rights to some popular franchises, including Narcos, Knight Rider, and Gordon Ramsey’s Hell’s Kitchen.

Yggdrasil Gaming

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 slots players, and their graphics are second to none. Check out Vikings Go Berserk, and Blood Moon Wilds as two of their top titles.

Playtech

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. 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.

Play’n GO

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. What really makes Play’n Go’s 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.

IGT

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.

Red Tiger

Red Tiger slots are some of the most sought after games in 2022. 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!

Red7 Slots

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.

Best slot games

The slot games most played by the BonusFinder UK team in August 2022 include classics like Starburst and Book of Dead.

🍀 Best Slot Sites for Winning Real Money

The BonusFinder experts are often asked which is the best UK slots site to win real money, but the answer isn’t that simple. One of the conditions of the licence granted by the UK Gambling Commission is that games must be fair, and the random number generators are tested to make sure that they are truly random. Although we may think that we are more likely to win at our favourite casino, the chance of winning a game is the same no matter where we play it.

When deciding what slot to play, look at the game’s payout percentage, or RTP (Return to Player). This tells you how much money you should expect to win for every pound you play. If the RTP of a game is 96% then over time you would expect to win 96p for every £1 you play.

Generally, the higher the RTP the more likely you are to win real money. However, some of the most popular games, like progressive jackpots, have a lower RTP and a high variance. These slots may only have a 92% RTP, but they give you the possibility to win big with massive jackpots. Many players find this more exciting than winning little and often on the high RTP, low variance slots, but with a higher reward comes more risk.

These are the key stats for some of the most played slots in the UK:

🎰 Online Slot 📈 RTP ⚖ Variance 🏛 Slots Site
Starburst 96.09% Low Party Casino
Book of Dead 94.25% High NetBet
Aloha - Cluster Plays! 96.42% Low Slotnite
Mega Moolah 88.12% Medium Zodiac Casino
Gonzo's Quest 95.97% Medium Hello Casino
Fire Joker 96% Medium Hopa
Jurassic Park Online Slot 96.67% Medium Mr Green
Narcos 96.23% Medium Video Slots
Rainbow Riches 94-96% Medium Grosvenor Casino
Immortal Romance 96.86% Medium Play OJO
Bonanza 95.98% High Mr Q Casino
15 Tridents 96.12% High 888 Casino

UK Slot Sites that Accept PayPal

There are a number of different payment options available to UK players wanting to play slots for real money. All casinos that are licensed in the UK are required to put strict measures in place to protect player funds, so you can rest assured that it is safe to transfer real money to all the sites we list.

Many UK players like to use PayPal, or other eWallets, to provide an extra level of security when playing online slots. We have collected a list of the best online casinos that accept PayPal, and their generous welcome bonuses. Do check the T&Cs carefully though, as often you need to use a debit card to claim a first deposit bonus at any UK slots site.

Mobile Slots

Every slot site we recommend works beautifully on smartphones for players who want to spin on the go! Some sites have dedicated mobile apps for an easy playing experience, but almost all can be played straight through the internet browser on your Apple or Android device. Check out our top slots bonuses for players on mobile and tips on how to get the most out of playing slots on your phone.

Some mobile casinos make it even easier to play slots on mobile by letting you pay by phone bill. If you are playing slots on your phone you may be able to pay-by-mobile and simply charge your deposits to your monthly bill. This is super quick and convenient, but be aware that there is normally a cap of £30 per day for deposits by mobile, and you may need to prove your phone bill has been paid before you can withdraw any real money.

Our favourite casino to visit and play mobile slots at is Mr Green. This established casino was one of the first to fully embrace the mobile market, and their sign-up bonus on mobile is 50 free spins with no deposit for their sensational signature slot game: Lucky Mr Green.

pay by mobile slots

In 2022 most online slots sites are designed to be played on mobile, and many will now let you pay by phone bill as well!
