Starburst (NetEnt)

starburst-slot-banner

Probably the internet’s most popular online slot game, the Starburst slot by NetEnt was released in 2012 but is still played online just as much today. Set in outer space and with 5 reels and 9 paylines, the gameplay is fast-paced and simple. It comes with just 1 bonus feature.

When a Starburst Wild appears on any of the 3 middle reels, the Starburst Wilds feature is triggered. The wild expands to give you a wild reel and a free re-spin. Look out for Starburst Wilds landing on the other 2 central reels as it could lead to 3 fully wild reels and/or up to 3 re-spins. With 500 x bet top wins, this cult favourite remains the king of free online slots.

Book of Dead (Play ‘n GO)

book-of-dead-slot-play-n-go

Play ‘n GO’s flagship release, the Book of Dead slot (also known as Rich Wilde and the Book of Dead) sees the intrepid adventurer head to ancient Egypt on a quest for riches. With 5 reels and 10 paylines, this excellently-produced game focuses entirely on the Free Spins feature.

With 10 free spins awarded, 1 symbol is randomly chosen to act as the special expanding symbol. When this symbol lands, it expands to fill the entire reel. If you get Rich Wilde as the expanding symbol, 5 Rich Wilde symbols will result in 5,000 x bet payouts. Due to its popularity, it’s the subject of many of the best casino bonus offers. On top of this, it’s normally the first port of call when you play slots for free.

Jammin’ Jars (Push Gaming)

jammin-jars-slot-banner

Head to the dancefloor and get into the groove with Push Gaming’s Jammin’ Jars slot. Play on an 8×8 grid, this cascading wins game is colourful, upbeat and will get you on your feet. It comes with colossal fruit symbols and Jam Jar Multipliers where wilds shift to a new position and multiplier increase with each cascade.

There is a Free Games feature where the multiplier increases with each collapse/cascade. Multipliers can only increase which could lead to 20,000 x bet max wins. With a high 96.83% RTP rate, Jammin’ Jars paved the way for countless more grid slots. Push Gaming is a mobile-first provider meaning all their games are free slots with no download.

Bonanza Megaways (Big Time Gaming)

bonanza-megaways-slot-big-time-gaming

The game that put Megaways on the map, the Bonanza Megaways slot (also known simply as Bonanza) by Big Time Gaming comes with 6 reels and up to 117,649 ways to win. On each spin, each reel contains up to 7 symbols each: the more symbols per reel, the more ways to win (or Megaways).

This mining themed game comes with Reactions for successive wins and a Free Spins feature where reactions can increase the unlimited win multiplier infinitely. With 26,000 x bet payouts, Bonanza has become the most popular of all Megaways slots.

Money Train 4 (Relax Gaming)

money-train-4-slot-payout

Join the bandits in their last ride of the rails in the Money Train 4 slot from Relax Gaming. Played on a 6×6 grid, this fantastic game focuses on the Money Cart Bonus feature which has an extra bandit and more special symbols than its predecessors.

It comes with 150,000 x bet max wins, which is much bigger than previous titles in the series. It’s become Relax Gaming’s most popular title and has claimed plenty of top awards in 2023. Every single aspect of this game has been improved since the previous release, and although the provider has hinted this will be the last one in the series, we’re hoping for another at some point.

Dead or Alive 2 (NetEnt)

Dead or Alive 2 slot NetEnt

Released in 2019, the Dead or Alive 2 slot by NetEnt is a cult favourite that takes you on a Wild West adventure with 5 notorious outlaws. This highly volatile heist benefits from 3 free spins features. They are all triggered by landing 3+ scatters. Land 5 of them though for a 2,500 x bet payout.

The best of them is the High Noon Saloon Free Spins feature where there are 2x and 3x sticky wild multipliers. This can lead to 40,500 x bet max wins per spin and 111,111.11 x bet top payouts overall in the feature. Boasting a 96.8% RTP rate, Dead or Alive 2 remains 1 of the most popular and played online slots ever made.

Tombstone RIP (Nolimit City)

tombstone-rip-slot-nolimit-city

Created by Nolimit City, the Tombstone RIP slot was released in January 2022 and is a Wild West themed game with a difference. With amputations, hangings and murder the order of the day, this controversial title is brutally insane and offers a hit frequency rate of just 9.08%.

With lots going on, the highlight is the Boothill Free Spins feature where there’s an increasing multiplier and random multipliers up to 999x. Extremely volatile, it does comes with 300,000 x bet max wins per spin. At time of writing, it’s the highest paying video slot available online. Due to the insane volatility, many players won’t dare play for real money so it has become 1 of the top free play slots.

Immortal Romance (Microgaming)

immortal-romance-slot-microgaming

Originally released in 2011 but remastered in 2020, the Immortal Romance slot is Microgaming’s most popular game. With a vampire theme, it offers 1 of the best soundtracks ever produced for an online slot game. Offering 5 reels and 243 ways to win, there is a random Wild Desire feature which awards up to 5 wild reels.

Then you have The Chamber of Spins features where there are 4 different free spins features on offer. With 12,150 x bet top wins and a 96.86% RTP rate, Immortal Romance is 1 of the go-to free play slots here at Online-Slot.co.uk.

Age of the Gods (Playtech)

Age of the Gods slot Playtech

Head to ancient Greece with the Age of the Gods slot by Playtech. With 5 reels and 20 paylines, Playtech’s flagship game focuses on Zeus, Poseidon, Hercules and Athena which all offer their own free spins feature and special modifier. This can lead to 50,000 x bet max wins per free spin.

On top of this, there are 4 progressive jackpots to be won. The current Ultimate Power Jackpot stands at £118,143.71. It pays out an average of £488,000 every 45 days. Combining excellent gameplay, lots of bonus features and jackpots, the free slots demo doesn’t have the jackpots as it’s not being played for real money. 

Rainbow Riches (Barcrest)

rainbow-riches-slot-barcrest

Last but certainly not least is the Rainbow Riches slot from Barcrest. Found in pubs, arcades and land based casinos across the UK, this Irish luck game has become a cult favourite amongst UK players. If you’re looking for free slot machines, this Rainbow Riches will most likely be the number 1 choice.

With 5 reels and 20 paylines, it benefits from 3 bonus features. Fun, simple to play and with 500 x bet max wins, Rainbow Riches is 1 of the top free slots in the UK and for good reason. As a result, Barcrest has created various spin-offs including a Megaways version that boasts 12,500 x bet top payouts.

Playing free slots online couldn’t be simpler. Choose the game you want to play and click on the ‘Play Demo’ button. The online slot game will load up and you just spin away till your heart is content. It’s that easy.

You’ll notice there is a demo/fun balance which allows you to play 1,000s of free spins. If your balance runs out, just refresh the page and start playing again. Here is how to play free slot games:

1 Choose the slot game + click/press the ‘Play Demo’ button
2 Select a bet/stake you’re comfortable with
3 Spin away till your heart’s content
4 Refresh the page if your balance reaches zero to start again

When you load up free online slots, the bet/stake will normally be the default value (normally £1-2). It’s important to play at the same bet/stake that you will would chose when playing for real money. This allows to get a feel of how long your money will go.

Also look out for how long bonus features or modifiers take to trigger so you know how it play for real money. All demo slots are exactly like the real money versions so it’s an actual representation of the slot game you’re playing.

This is the case with free slot machines which are the same online. With no money to lose, the key is to experience the real money version with no risk whatsoever.

We recommend you check out the Paytable which shows the payouts for each simple and gives you details of the bonus features on offer. In most cases, it will highlight the RTP rate and max win. However, our free slots tend to have Autoplay and Turbo Mode functions which are not available to UK players in real money mode.

All our free slot games include detailed reviews + trusted UK casinos to play them at.

Finally, our free slot games are coupled with a detailed and honest review. This includes details on the slot’s details (stakes, RTP, volatility, max win potential), theme (look, feel, symbols + symbol payouts, soundtrack), bonus features and summary/verdict. For full details, check out our How We Rate page.

You will also find a list of trusted slot sites you can play the slot game at. We only list UK online casinos where the slot is available. There is no point in having a long list of sites where the game may not be available at. Here at Online-Slot.co.uk, we carefully select the best casino sites which offer the slots so you get the best experience.

In addition to this, we’ve teamed up with the top slot sites to offer you free spins. Some offers are no deposit meaning they are essentially free slots to play.

Free Online Slots Features to Consider

In addition to the above section, playing free slots for fun will let you understand how to play a slot game online. Even though online slots are games of chance and random outcomes, there are a few generic slot features to consider.

Mimicking real money slots, here are some slot features you should pay attention to in order to get the most out of your free play experience.

Autoplay Despite not being available in the UK, Autoplay allows you to spin the reels automatically. Most of our free demo slots have this functionality.
Turbo Mode Also known as Quick Play, this allows you to spin the reels quicker than usual. This isn’t available on real money slots in the UK.
Reels/Paylines Look in the Paytable/side of the game to see how many reels and paylines you’re playing with. Some are grid slots so this is explained in the Paytable.
Settings This section allows to enjoy free slot games with or without sounds/music.
Bonus Buy Not available to UK players, it allows you to buy your way into the bonus features (for free of course with play money) and sample what the slot has to offer.

Enjoy Free Mobile Slots

free-mobile-slots

According to StatCounter, 48.48% of internet usage comes from mobile devices with 46.52% coming on desktop devices (laptops/PCs) and 5% from tablets. With more of us now opting to use our smartphones for everyday life, no downloading of free slots has also grown significantly.

In 2021, according to USwitch, UK mobile phone users spent an average of 4 hours per day on their devices. Increasing year on year, it’s predicted that 95% or 65 million people will be using a smartphone by 2025. Slot providers focus more and more on mobile play with many of them being mobile-first slot providers. The likes of 4ThePlayer and ELK Studios are examples of this.

HTML5 technology detects what device you’re using + adapts to offer the correct version.

With HTML5 technology being used, slot providers can build a single slot version that adjusts to all devices, including smartphones, tablets, laptop and/or PCs. When you fire up free mobile slots, the technology detects what device you’re using and adapts to offer you the appropriate version.

Furthermore, all games are free slots with no downloads. Long gone are the days of downloading programmes (i.e. Microgaming’s VIPER software). You may need to download a dedicated casino mobile app but that is a different matter.

Free slots online are compatible with iOS, Android, MAC and/or Windows operating systems. This is true at Online-Slot.co.uk or at your chosen slots site. Real money versions work in exactly the same way too.

Finally, the good news is that all free to play slots are available to play on mobile and tablet devices. Megaways slots may look better on a laptop or PC device (due all the moving parts) but you won’t lose anything playing on a handheld device.

Play Free Jackpot Slots

Also on offer here at Online-Slot.co.uk are free progressive jackpot slots. Whilst you cannot win the life-changing jackpots on offer, free online slot games allow you to see how to win the jackpots. Demos are also a nice way to test these types of games out as you won’t find them at no wagering casinos for example as part of any welcome offer or anything like that.

It’s important to note that some jackpot slots won’t display the jackpot amounts when playing in demo mode. Some do. However, in our detailed reviews, there are jackpot tickers displaying the progressive jackpots on offer when playing for real money.

Explore New Slots Demos

With over 5,000 free demo slots available at Online-Slot.co.uk, new games are being added almost daily. This means plenty of new slots demos to try. Check out our new slots section for the latest releases which include free slot games demos.

All free new slots for fun are available to play at UK casinos. Here at Online-Slot.co.uk, we don’t offer demo slots or reviews of games that aren’t available to UK players. Our focus is entirely on UK slots players. Finally, it’s important to note that all free slot games are released once the title is available to play for real money.

Understanding Demo Slots Verification

agechecked-uk-age-verification

As of May 2019, all free online slots are subject to age verification measures. This is a legal requirement by the UK Gambling Commission and is to ensure that children and young people are not exposed to slots, which are for over 18s only.

We are proud to announce that Online-Slot.co.uk was the first portal in the UK to implement age verification. As a result, users here and other sites will need to perform a free age check in order to play demo slots in the UK.

We’ve teamed up with AgeChecked which offers you a simple and multi-pronged solution. There are 4 ways to verify your identity/age:

1 Electoral Roll: enter personal/address details
2 Driving License: enter personal details + driving license number
3 UK Mobile: enter your email address + mobile number
4 Credit Card: enter your card details

Importantly, AgeChecked will not store or share your details as they are used only for verification purposes. You can also create an AgeChecked account which makes it easier in future to verify your age/identity.
