In this guide, we cover everything you need to know about playing free online slots. You'll find out about different game types, themes, bonus games, and the perks of playing for free.

If you're new to slot games, one of the best ways to play for free is by checking out free demo slots. These are basically trial versions of real money slots, and you can find many of them featured on this page.

This guide will also show you the ins and outs of playing free slots, including the UK gambling rules and where to find the best free mobile games. Keep reading to see why free slot games could be a top choice for any UK bettor.

If you're a UK slot player, you can play free games by signing up at a licensed UK casino. Or you can check out a bunch of exciting free slots right here. We've broken down three ways you can find a specific slot game in our games library, which you can see above:

• By game title. 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.
• Click on the “Sort” button. Use the button to pick 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.
• Use the “Filter” function. This tool helps you select games by provider, features, volatility levels, or themes. Use it if you already know which features you would like to see in a slot but don’t have an exact game in mind.

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. This means you can find these games at pretty much any of our recommended online casinos.

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. Here, the prize pool increases with every stake.

You can play demo versions of several jackpot slots at our recommended sites. Though free slots with progressive jackpots are a little harder to come across. Even so, trying out jackpot slots for free is a great way to weigh the risk before signing up at a casino. It's also a good way to see if depositing money via one of the casino payment solutions and playing with your cash is worth it.

Free Egyptian Slots

UK players can find free slots online in every shape, size, and theme imaginable. Yet, Egyptian slots are one of the earliest and most enduring slot themes to exist. These games remain popular with bettors in the UK and across the globe. 

Free Cluster Pays Slots

Standard free demo slots contain a set number of winning paylines. But, games that use a Cluster Pays mechanism pay out anywhere on the grid. If you form clusters of the same symbol, you'll win and also bring in some extra fun and surprises to the game. Since NetEnt released Aloha! Cluster Pays in 2016, hundreds of games now use the same mechanism. 

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 have "high," "low," or “medium” volatility. High volatility slots have a lower win frequency but bigger prizes. 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 good opportunity to test some volatile games. Trying out demo slots will give you thrills without spending or losing money. And if you want to play for real later on, finding an attractive slots deposit bonus at Casinos.com is easy.

Free Penny Slot Machines

Free penny slots do exactly what they 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 slots in demo mode!

These games are a great way to dip your toes in the water if you're a beginner. Start by playing the demo version of these low-stakes games. Then transition to the real deal for a taste of real money wagering with minimal financial risk.

You can play slots on your iOS or Android device at all our recommended online casinos. Thanks to HTML5 technology, these games are responsive and adaptable. So, playing at a casino on a mobile is as good as on a desktop.

To begin, load your chosen free mobile slot on your mobile browser and voilà! You can now play some of the best free slot games anywhere, anytime.

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. These apps keep you updated on the newest game releases and send you alerts if there are any new bonus offers.

In our experience, the following online casinos are some of the best:

A good way to explore our free slots library is by picking a slot theme. Here are some popular topics you'll find at our top established sites and new casinos.

Free slots come with numerous advantages that real money slot games can’t offer. Many UK punters play slots for the thrill. As such, free demo slots have always been 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. Studios like NetEnt and Microgaming often put an exclusive spin on their games to make them stand out.

When you play free slot games, you can check out cool features without having to bet real money. This means you can take your time getting to know a developer's style. With Wazdan slots, for example, you can adjust volatility and spin speed, or choose the 'big screen' mode.

You will also get to try different slots to understand better what works for you. With so many variations out there, it's always good to explore.

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.

Free Slots Regulations in the UK

At Casinos.com, we only recommend casinos licensed by the UK Gambling Commission (UKGC) and other trusted authorities. To get a license, a casino has to follow UK-specific rules about keeping players safe and making sure the games are fair when people gamble 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 use age verification software to ensure that only UK visitors of legal age can play demo games and sign up for online casino accounts.

Proof of Identity

All our recommended casinos ask every player to confirm their age and identity with documents like a passport or driver's licence. If these aren't presented, the casino can refuse to process your withdrawal request. 

Some UK casino sites may even block your first deposit until you verify your account. That applies to any possible methods of paying and withdrawing at slot sites with PayPal, Neteller, Skrill, and similar casinos.  

Once you prove your details, you can play slots or other games, such as online roulette for real money.

Responsible Gambling

All UK casino operators highlighted on this page are serious about problem gambling. They help you stay safe and in control. 

These are some of the most effective tools best gambling sites with UK slots offer: 

• Limits on the number of sessions you play
• Deposit amounts
• Your playing time
• Time-outs
• Self-exclusion
• Reality checks
• Advice and links to addiction support organisations.
