In this guide we have covered everything you need to know about playing free online slots, including game types, themes, bonus games and the benefits of playing for free (trust us, there are plenty!).

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.

Anyone over the age of 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 should not 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.

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. Many 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 usual debit card or want to use an e-wallet at slot sites with PayPal, Neteller, Skrill, and more. Once you do, you'll be able to play slots as well as other games like online roulette for real money.

Additionally, most UK casino operators, including those highlighted on this page, take problem gambling seriously. The top recommended sites on this page provide responsible gambling tools to help you maintain responsible gambling habits. These include limits on numbers of sessions, deposit amounts and time played alongside time-outs, self-exclusions and reality checks. You’ll also find pages full of advice and links to addiction support organisations.

How to Choose Which Free Slots to Play

Players in the UK can access free slots by registering at a licensed UK casino and verifying they are over the age of 18. After doing so, you can easily access a vast range of the most exciting free slots on our page. There are three ways you can find a free slot game to enjoy, 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 have an idea of the features you like to see in a slot but don’t have an exact game in mind.

Types of Free Online Slot Games

When it comes to playing free slots online, your options are limitless. UK casinos have almost as many free slots as real-money games in their collection, 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 UK punters. And of course, if you decide you want to try to win real money on slots, you'll know which games you like best.

Here are some of the most popular slot types:

Free Megaways Slots

Australian developer Big Time Gaming was the first brand to release Megaways online slots. 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 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 measure of risk involved. Each free demo slot you come across will be measured as “high”, “low”, or “medium” volatility. High volatility slots have a lower hit frequency but higher payout, and vice versa.

Though free demo slots won’t pay out real money, you can use them to play games you might usually avoid. With no financial commitment involved, you can play demo versions of high volatility slots and enjoy the high-risk, high-reward experience (without an actual risk, of course). And if you do want to later play for real, finding an attractive slots deposit bonus to increase your bankroll shouldn't be too hard.

Free Penny Slot Machines

Penny slots do exactly as they say 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. 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 Slots on Mobile Devices

All of our recommended casinos offer free mobile slot games, allowing you to play when on the go from any iOS or Android device. These demo games are built on and optimised with HTML5 technology, which ensures they are responsive and adapt to any screen size. Therefore playing at a casino on a mobile is just as good as on a 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 replicas of real money games. Playing them on your mobile device allows you to access free mobile slots from anywhere, anytime.

Many online casinos also offer compatible casino apps for iOS and Android devices, streamlining the process even further. The best online casino apps will have a wealth of slot games to play, so they are well worth checking out. Alongside alerts and notifications on the hottest game releases and the latest bonus offers, mobile casino apps also provide enhanced usability and connectivity. Mobile casinos are a great way to enjoy casino games on the go wherever you are in the world.

Free Slots with no Downloads

The first (and easiest) way to access free slots is by playing the games featured on this page. With our recommended free slots, no download is required. We spend time sourcing the best demo slot games for you to enjoy, making sure to include a massive variety of 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 always find something new and exciting to play.

Alongside playing free demo slots on this page, there are numerous ways to access games for free. We’ve listed some of the best ways to find free slots 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 extremely common for UK casinos to offer free spins 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: If you sign up to a UK online casino bonus, you'll be able to use your free credit to wager on your favourite slots. You’ll be playing on real money slots, which means you have the chance to cash out your winnings. These bonuses are based on a deposit, so they are not completely free (and wagering requirements will still apply). However, they offer a significant boost to your bankroll and a generous amount of free spins to use on real money games.
  • No deposit bonus: These promotions allow you to receive credit to spend on slots without requiring you to first deposit money. Unfortunately they are harder and harder to find these days, so if you come across a no deposit bonus 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 specified 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 on 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 Slots Online?

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 Slots 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 Free Slots Game 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 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.
