How To Play Free Online Slots

Our casino experts make it their business to play at the best slot sites in the UK, so they're experts on free slots.

In this guide, we've covered everything you need to know about playing free online slots, including game types, themes, bonus games, and the benefits of playing for free. It should be stressed that one of the best ways to play these games for free is via free demo slots. These are simply the demo versions of real money slots, of which many are featured on this page.

This guide will also cover the technicalities of playing free slots, such as UK gambling regulations and where you can access the best free mobile games. Continue reading to discover why free slot games could be a great option for any UK bettor.

Free Slots Regulations in the UK

Here at, we only recommend casinos with valid operating licences from the UK Gambling Commission (UKGC) and other reputable gambling authorities. To hold such a licence, a casino must adhere to UK-specific laws and other player safety and fair gaming regulations around gambling online.

You might think if you're playing for free then why not opt for no account casinos. We'd never recommend this. These sites will be unlicensed, and potentially dangerous. Even if you want to try some demo slots, you'lll usually need to make an account when playing in the UK.

Anyone over 18 can gamble at an online casino for real money in the UK. However, these laws also apply to playing free slots, as underage players shouldn't be able to access online casino games of any kind. We implement age-check software to verify that only UK visitors above the legal age can play demo games and register at online casino accounts.

Proof of Identity

Beyond this, the licensed casinos we recommend require every player to confirm their age and identity with government-issued documents before processing a withdrawal request. Some UK casino sites won’t let you make your first deposit until you verify your account. That applies to any and all possible methods of paying and withdrawing, whether you're using your debit card or want to use an e-wallet at slot sites with PayPal, Neteller, Skrill, and more. 

Once you prove you are who you say you are, you'll be able to play slots as well as other games like online roulette for real money.

Responsible Gambling

Additionally, UK casino operators, including those highlighted on this page, take problem gambling seriously. The best gambling sites with UK slots on this page provide responsible gambling tools to help you stay safe and in control. These tools include limits on the number of sessions you play, deposit amounts, and your playing time, alongside time-outs, self-exclusion, and reality checks. You’ll also find pages full of advice and links to addiction support organisations.

How to Play Free Demo Slots in the UK

UK slot players can access free slots by registering at a licensed UK casino and you can access a wide range of the most exciting free slots via this page. There are three ways you can find a certain free slot game here, which we have detailed below.

  1. Type in your favourite game title in the search box above. This is the most efficient way to find a specific slot game you’re looking for.
  2. Click on the “Sort” button to choose progressive slots or to sort the list by release date or RTP. This way, you can see the newest releases first or find games with the biggest potential jackpots.
  3. Use the “Filter” function to select your favourite software providers, features, volatility level or themes. This is a great tool to utilise if you know which features you like to see in a slot but don’t have an exact game in mind.

Types of Free Online Slots

When it comes to playing free online slots, your options are many. UK casinos have almost as many free slots as real money games, including the latest and greatest releases from top software providers. 

These games have all the excitement and none of the risk of real money games, which is why they’re such a hit with certain UK players. And of course, if you decide you want to try to win real money on slots, you'll already know which games you like best.

Here are some of the most popular free slot types:

Free Megaways Slots

Australian developer Big Time Gaming (BGT) was the first brand to release Megaways slots online. These games use a unique shape-shifting feature known as the Random Reel Modifier. The modifier produces a random number of symbols on every spin, resulting in thousands of paylines and huge maximum wins.

The mechanism first appeared in BGT’s 2016 slot Dragon Born, though it was Bonanza that really put Megaways on the map. Dozens of developers have since used the mechanic to up the ante on their own slots, meaning you can find these games at pretty much any of our recommended online casinos. Popular slots include White Rabbit Megaways, 88 Fortunes Megaways, and Divine Fortune Megaways.

Free Jackpot Slots

Real money jackpot slots allow players to score a massive prize with a single spin. Even more lucrative than regular jackpots are progressive jackpot slots, where the prize pool increases with every stake.

You can play demo versions of several jackpot slots at our recommended sites, though free progressive jackpots are a little harder to come across. Still, playing jackpot slots for free is a great way to weigh up the risk involved before signing up at a casino, depositing money via one of the casino payment solutions offered, and playing with your real money bankroll.

Here are some online casinos known for their fantastic selection of real money and free jackpot slots:

Free Egyptian Slots

UK players can find free online slots in every shape, size and theme imaginable. However, Egyptian slots are one of the earliest and most enduring slot themes to exist. These games remain extremely popular with bettors in the UK and across the globe. From casino staples like Eye of Horus to modern classics like Book of Dead, developers are constantly finding ways to reinvent the (chariot) wheel.

Free Cluster Pays Slots

Standard free demo slots typically contain a set number of winning paylines. However, games that use a Cluster Pays mechanism pay out anywhere on the grid. Forming clusters of the same symbol will constitute a winning payline, adding a layer of unpredictability and excitement to the gameplay.

Since NetEnt released Aloha! Cluster Pays in 2016, hundreds of games now use the same mechanism. Some exciting new releases include Clash of the Seraphim, Rainbow Riches: Racking Up Trinkets and Sky Piggies.

Free High Volatility Slot Machines

The volatility of a slot refers to the predictability of how each round will end. Each free demo slot you come across will be measured as “high”, “low”, or “medium” volatility. High volatility slots have a lower win frequency but bigger prizes, and low volatility slots have a higher win frequency but wins tend to be smaller.

Though free demo slots won’t pay out real money, it's a chance to play games you might usually avoid like highly volatile games. With no financial commitment involved, you can play demo slots in the UK, and a high-risk, high-reward experience, without the concern of losing money. And if you want to play for real later on, finding an attractive slots deposit bonus reviewed at is easy.

Free Penny Slot Machines

Penny slots do exactly what it says on the tin. These games offer stakes as little as £0.01, making them perfect for budget betting. Though it seems impossible, you can play these games for even less than a penny by wagering on free demo slots!

Free penny slots are a great way for beginner bettors to dip their toes in the water. Why not start by playing the demo version of these low-stake games, then transition to the real deal for a taste of real money wagering with minimal financial risk?


Free Online Slots for Mobile

All of our recommended casinos offer free slots for mobile, allowing you to play on any iOS or Android device. These demo games are built on and optimised with HTML5 technology, which ensures they're responsive and can adapt to any screen size. Therefore, playing at a casino on a mobile is just as good as on desktop.

Simply load your chosen game on your mobile browser and voila! Alternatively, you can access free demo versions of your favourite slots by registering at a casino on mobile. The sites we recommend offer free mobile versions of real money games. Playing on your mobile device allows you to access slots anywhere, any time.

Many online casinos also offer compatible casino apps for iOS and Android devices. The best online casino apps have a wealth of slot games to play, so they're well worth checking out. Alongside alerts and notifications on the hottest game releases and the latest bonus offers, mobile casino apps provide enhanced usability and connectivity.

The following online casinos offer an unparalleled mobile experience:

Free Slots, No Download Needed

The easiest way to find free slots to play online is by via the games featured on this page. With our recommended free slots, no download is required. We source the best demo slot games for you, including different themes and bonus features from the world’s best providers. 

We also provide a free slots calendar that details the latest game releases, so you can find something new and exciting to play all year round.

Alongside playing free demo slots on this page, there are numerous ways to access games for free. We’ve listed some of the ways to find the best free slot games and play for fun below.

  • Play free games at top casinos: sign up at one of our top slots sites and browse its slot collection. Most of the slots sites listed will allow you to play free demo versions of their games, provided you have a casino account and have verified your age.
  • Free spins bonus: it’s common to see casino free spins in the UK dished out to new players. Browse our list of top recommended sites to claim some no deposit offers, and enjoy free spins to play for real money without using your own cash.
  • Deposit bonuses: you can find a UK online casino bonus at many sites which gives you bonus money you can use on slots. With the bonus, you’ll be playing on real money slots, with the chance to win cold, hard cash. These bonuses are usually based on a deposit, so they're not completely free (and wagering requirements usually apply).
  • No deposit bonus: these promotions give you bonus cash or free spins for slots and you don't have to deposit real money. Unfortunately, they're harder to find these days, so if you find no deposit bonus at a casino, grab it with both hands!
  • Free Chips: although not a standard online casino term in the UK, some sites give away free chips to use on certain slot games. Depending on the terms and conditions of the bonus, free chips could be marketed as slots bonuses or free spins.
  • Free Play: many casinos offer a “free play” option where you can try the games for free with free-play funds credited by the casino. While many established operators do this, the best new casinos are even more likely to offer this as they seek to establish themselves in the market. However, this method is not quite the same as playing demo games, as when your virtual balance reaches zero, your free play session is over.

Why Choose Free Slot Games?

Free slots come with numerous advantages that real money slot games can’t offer. Many UK punters play slots for the thrill of the game rather than the potential cash reward, so free demo slots are quickly becoming a preferred way of playing for some players.

Explore Slot Features

Every slot has its own unique features, whether that’s free spins, progressive jackpots, expanding reels or all of the above. Many online video slots also come with an additional bonus round you can trigger by landing a specific combination of symbols. In contrast, others offer you the chance to gamble your winnings for double the payout. While these features all add a layer of intrigue to the normal gameplay, they may be a little confusing for beginners. 

Playing free slots with free spins and bonus games is the quickest way to get to grips with these additional features. Once you feel confident with the mechanisms of a game, you can up the ante and start wagering with real money. That said, there’s no reason to risk your real money if you’re enjoying the games for free!

Compare The Best Free Slot Games Providers

We source our free slots from the best providers in the business. Industry-leading developers like NetEnt and Microgaming put an exclusive spin on their games to make them stand out from the crowd.

Playing free slot games lets you explore these exclusive features without the pressure of real money wagering, meaning you can take your time getting to a developer’s personal style. Wazdan slots, for example, come with a suite of customisable tools, including adjustable volatility, extreme spin speeds and a ‘big screen’ mode.

Exploring different software providers is a surefire way to ensure you find the best free slot games. You will also get to try out different types of slots, giving you a better feel for what works for you, which is important given there are plenty of variations.

Play New Free Slots 

Software providers regularly release new online slots in the UK to update their portfolios. By making the most of free slots, UK players can enjoy these new releases without investing real money. And of course, you don't have to only play these on your computer, since these mobile slots in the UK are generally released at the same time as on desktop.

If you like the game, you might want to place a real wager for a chance to win. Alternatively, you can continue to play these hot new slots for fun.

Pros and Cons of Playing Free Demo Slots

Figure out which slots you like and dislike without eating into your bankroll.
Take more risks and figure out if they’re worth repeating with real-money spins.
You don’t get to withdraw your winnings as real money.
Some players find the risk of real money wagers the most exciting part of a game.
