The Best Slot Sites

Slot sites are hugely popular with UK players, providing a top-rated online casino experience where you can access thousands of slot titles from a wide range of game studios and developers.

Slots sites are the same as online casino sites in that they have generous welcome offers, loyalty and VIP schemes, a wide range of payment options and knowledgeable customer support agents. But instead of packing their game portfolios with other online casino games such as blackjack, roulette, poker, instant win and lottery betting, they stock more slot games that anything else.

Below, we tell you everything you need to know about slots available to UK players. But if you want to play right now, try our recommended slot sites below:

The Best UK Slot Sites 2022

Slot Sites Explained

Slots sites are exactly what they say they are – online casino sites that offer a massive choice of slot games from hundreds of slot providers, developers and studios.

You still receive the same experience as you would at other types of online casino like new online casinos, best online casino sites and live dealer casinos, but the focus is very much on slots.

It is not unusual for slot sites to stock their games lobbies with more than 1,000 of the best slots, but brands such as Videoslots offer 3,300+ slot games.

This means you can access different types of slots – classic, video, three-reel, five-reel, Megaways, jackpot and so on from the best selection of slot providers and developers.

This includes the likes of NetEnt, Microgaming, Big Time Gaming, Red Tiger, Push Gaming, Thunderkick, Play’n GO, Yggdrasil Gaming, IGT, Scientific Games and many, many more.

While slots sites focus on slots, most also offer other online casino games such as roulette, blackjack, baccarat, poker, instant win, live dealer and even lottery betting.

But because slot sites focus on slots, the number of online slot games offered far outweighs the number of table and live dealer games offered.

What’s more, you can still enjoy other aspects of playing at online casino sites such as welcome offers, on-going bonuses and rewards, loyalty schemes and a good choice of payment options.

Why You Should Play at Online Slot Sites

If you love playing online slots, then you really should play at slot websites. The good news is that for UK players, there are plenty of sites to choose from.

While each slot site offers something a little bit different, when playing at any of our recommended brands you can expect the following:

The widest selection of slot games

The UK slot sites that make our list offer at least 500 of the best slots, while most offer more than 1,000 and some even offer upwards of 3,000 slot titles.

Games are offered from a huge range of providers, from some of the biggest names in the market such as Big Time Gaming and Red Tiger to up and coming developers like Northern Lights Gaming.

This means players can access every slot format available, including three-reel, five-reel, Megaways, classic, video, jackpot and more.

Generous welcome offers

Slots sites like to welcome players with a generous offer, which usually consists of a deposit bonus combined with free spins on popular slots such as Starburst or Gonzo’s Quest.

Some of the top-rated slot sites just offer free spins as the welcome bonus, and in some cases free spins come with no wagering requirements whatsoever.

PlayOJO and Videoslots are two of our most popular sites that offer wager free welcome spins.

On-going bonuses and promotions at slots sites

Once you have signed up to a slot site, you can expect to be treated to on-going bonuses and promotions to add even more value to your play.

Some of the bonuses you can expect at slots website include:

Read our guide to online casino bonuses and promotions

Some of the best online slot websites also run promotions with incredible prizes up for grabs.

Play Ojo, for example, runs competitions throughout the year where players have the chance to win once in a life-time trips to places like Australia and Las Vegas.

To enter these promotions, you usually have to make a deposit and wager a certain amount on qualifying games to earn a ticket to the prize draw.

Slot tournaments and reel races

One of the best aspects of playing at UK slot sites is that many run thrilling slot tournaments and reel races with awesome prizes up for grabs including cars, tech, cash and free spins.

Slots tournaments see players make a deposit and then wager on specific games where they earn points for landing certain wins or triggering features.

Points are logged on a leader board with the winner announced once the tournament closes.

The good news is that prizes often pay down to the top 100 places, so you are in with a good chance of winning something. Outside of the top ten places, this is usually free spins.

Innovative loyalty schemes

As well as offering top slots games, the best slots sites also like to offer players innovative loyalty and VIP schemes to reward them for playing at their site.

Loyalty schemes are usually points based and see players accrue points on every bet or wager placed. The more points you earn, the more levels you clear and the more perks you unlock.

Loyalty schemes are often hooked up to VIP clubs, which are reserved for high rollers and players that reach the highest tiers of the loyalty scheme.

Banking at slot sites

The sites that make our list of recommended brands provide players with a wide range of payment options to deposit into and withdraw from their real money wagering accounts.

This includes Visa, Mastercard, Skrill, Neteller, PayPal, Paysafecard, Apple Pay and bank transfer.

Transactions times are super-fast, too. Deposits are instant and withdrawals can take place in a matter of hours and no longer than five working days.

All transactions are safe and secure, with UK slots sites required by the Gambling Commission to use state-of-the-art encryptions and firewall technologies to protect your money and your data.

Different Types of Online Slot Game

Slot sites are all about slot games, so we thought it would be a good idea to break down the different types of slot game you will find in slot site game lobbies.


Also known as classic slots, these are simple online slot games based on traditional land-based slot machines. They have three rows and three reels and, in most cases, a single payline.

They do not come with as many bonus features as modern video slots, but still provide plenty of excitement and big-win potential.

A member of the Find My Casino team won more than £800 for a £0.50 spin when playing a classic three-reel slot.


Also known as video slots, these modern online slot games have three rows and five reels with multiple paylines that go across, diagonally and up and down, providing more ways to win.

Five-reel video slots also come packed with a huge range of bonus features, such as Wilds, Multipliers, Free Spins, Mini-games and more.

Some forward-thinking slot providers have pushed the boundaries even further, developing slots that have upwards of seven reels, while others expand and contract.


Big Time Gaming came up with the Megaways concept back in 2016 and most consider it to be the next evolutionary step in online slot games.

Megaways is a random reel modifier that changes the number of symbols that appear on each reel during a single spin.

In short, this means that with every spin a different number of symbols lands on each reel, providing tens of thousands or even hundreds of thousands of ways to win.

Explainer: What are Megaways slots

Big Time Gaming actually licences Megaways to other game developers, which means you can play Megaways slots from providers such as Blueprint Gaming, Red Tiger, Scientific Games and more.

Daily Drop

Daily Drop Jackpot slots were developed by Red Tiger and combine the provider’s chart-topping slots with jackpots that must pay out before a certain time each day.

Daily Drop Jackpots are hugely popular, with some online slot sites creating dedicated lobbies where you can easily access Daily Drop slots.

Explainer: Daily Drop Jackpot slots


Jackpot slots offer players the chance to win life-changing prizes that run into the tens of millions of pounds in some cases.

Microgaming’s Mega Moolah and NetEnt’s Mega Fortune are the two biggest jackpot slots, with UK players having won jackpot prizes in excess of £16million in the past.

The best slot sites will have a dedicated lobby for jackpot slots, so you can quickly access slots with the biggest prizes available to UK players. 

Best Slots Games Providers

Such is the popularity of slots sites, there are now hundreds of slot studios and providers that design, develop and launch the slots that you find in game lobbies. The best slots casinos in the UK normally have at least one of the most famous game providers and often include many to offer an exciting array of quality slot game options. Providing quality and differentiation are key decision points as they are fundamental to creating an online casino experience that is identifiable with the casino brand and that customers trust.

To help with this, we've curated a list of the top slot developers of 2022 to help you choose a casino that suits your slot game preferences.


A pioneer in games, NetEnt combines stellar graphics, exciting storylines with unique characters, and winning chances. Some games that you might have heard of include “Gonzo’s Quest”, “Starburst”, “Dead or Alive”, and many more.


Microgaming is widely known for its games with good graphics and slick gameplay. But more importantly, this provider often links bonus rounds to their slots to make the most of your time on the machine. 

If you’ve played in casinos that have this developer, then you must know “Mega Moolah”, “Jurassic Park”, and “Atlantis Rising”.

Pragmatic Play

Aside from regular slots, Pragmatic Play has a long list of video slots, jackpots, progressives, and even 3D slots. This developer always works on providing games that have average to high RTP between 96-97%.

Games that you can find with this provider include “Queenie”, “Might of Ra”, “Gates of Valhalla”, and more.


After 2 decades on the market, Playtech has managed to stand hand in hand with some big names that have been present since the early 90s. Its entertaining games, coupled with great graphics and sound, make it one of the leading game developers. 

The serial “Age of Gods” is the most famous game, while others include “The Dark Knight”, Fire Blaze”, etc.


Yggdrasil offers stellar games with great graphics and fantastic storylines. Aside from the classic slots, there are jackpots and video slots, each with different volatility levels and payout times. 

“Vikings Go Berzerk”, “Frost Queen”, and “Vikings Go To Valhalla” are just some of the names linked to this provider.


Being one of the oldest game providers on the market, Novomatic constantly creates new entertainment mechanics for players. They mainly focus on slots with good graphics and various bonus features.

Games such as “Book of Ra” or “Book of Atlantis” are part of the gaming library of this provider.

Play ’N Go

If you're playing slots from your mobile, then Play ’N Go games are the right choice. The games have stellar graphics and easily adjust to your small screen. “Merlin And The Ice Queen Morgana” and “Secret Of The Dead” are some of the most renowned games from Play ’N Go.

The Best Online Slots and How To Find Them

Finding the best online slots for UK players can be tough. There are so many games to choose from and different slots appeal to different players.

This is why operators offer players such a wide range of slots to choose from. But how do you find the top UK slots that meet your needs?

It is important to consider what you are looking for in a game. When we decide which games to play, we consider these factors:

  • Slot theme – the look and feel of the game must be appealing
  • Slot features – does the game include Wilds, Multipliers, etc
  • Slot return to player – is average amount returned to players favourable
  • Slot volatility – does the game pay out a little and often or a lot and infrequently

Of course, you may have preferred slot providers and only play their games.

Either way, the good news is that all of our recommended slot sites offer powerful search tools to help you find the best slots for you.

You can usually filter games by provider and in some cases by other factors such as reels, features, volatility, return to player and more.

Once you have found a slot game you like, remember to “Like” it so that it is added to your favourite games list, making it easier to come back it next time you visit the site.

Online Slots RTP

Before you start spinning the reels, we advise you to look at the RTP and volatility of the slot. An RTP tells you how much that slot can give you over a period of time. Usually, players prefer slots that have higher RTP because they could bring more frequent wins in the long run. 

Simply put, this is a mathematical equation that shows you how much you can win and what goes to the casino. For example, if the RTP is 95%, the house gets 5% of your wager. So after hundreds of spins, £0.95 of each £1 spun will be returned to the player, whereas the casino gets £0.05.

On the other hand, volatility is a risk measure. Simply put, this tells you how risky a slot can be. Those with high volatility have a more extended series of no paying or low paying spins but may culminate with one big win. Low volatility turns the other way - more frequent wins, but the amount is smaller.

The volatility doesn’t influence the RTP of a slot, but they both impact the player's winnings. You should always go according to your bankroll. If you have a smaller amount, a game with high RTP and low volatility can be a suitable choice to keep you playing for a longer time.

Bonuses at UK Slot Sites

For some players, bonuses are a deciding factor when it comes to choosing which slot sites to play at, but there are some things to keep in mind when it comes to welcome offers and bonuses.

Even at the best UK online slots sites, bonuses and promotions come with terms and conditions and in particular wagering requirements (WR).

A wagering requirement is the amount of times a cash bonus or free spins winnings must be wagered before you can withdraw the bonus or winnings as real money cash.

Here is an example of a slot site welcome offer and the wagering requirements that come with it.

Welcome offer: 100% deposit match up to £10 plus 10 free spins on Starburst

Wagering requirement: x35 on the deposit bonus and x40 on free spins winnings

You accept the full deposit match up to £10 and win £50. You also win £20 from the free spins.

This means that you must wager the £10 bonus x35 – or gamble £350 – before any bonus winnings can be withdrawn as cash.

You must also wager your free spins winnings x40 (£20 x40 = £800) before your free spin winnings can be withdrawn as cash.

Some players enjoy the thrill of completing the wagering requirement, while others would rather not take the bonus and simply play with their own money.

It really is up to you and whether you believe the welcome offer or bonus provides genuine value to your play – here at, we usually prefer to play with our own cash.

Other bonus terms and conditions to be mindful of include:

  • Max bet limits
  • Max win limits
  • Time restrictions on WR

Our online slot site and online casino reviews list all of the key terms and conditions that come attached to welcome offers and bonuses – we also list significant and full T&Cs on our casino cards.

Mobile Play

 Mobile slot sites allow you to access UK slots from your smartphone or tablet, no matter where you are or what you are doing.

Mobile slots sites fall into two categories – those that are accessed via dedicated iOS and Android apps and web browser, and those that are accessed via web browser only.

In most cases, the best mobile online slot sites are accessed via an app, which is downloaded from the Apple App Store or Google Play store.

The difference between web browser and app is minimal – some of the best mobile slot sites are web-browser only – but those accessed via a dedicated app tend to be slightly superior.

The good news is that regardless of how you access mobile slots sites, you can still enjoy a huge range of titles from all of the major game developers.

In most cases, all of the slot games offered on desktop are also available on mobile. This is because they are now built in HTML5 which allows for a seamless experience across all channels and devices.

New UK Slot Sites

Just like new online casinos, new sites launch in the UK all of the time.

Each new best UK slots offers something a little bit different, from the theme and design to bonuses and promotions via the way players are rewarded for their loyalty.

Not all new slot sites are created equal and some are much better than others. Of course, all of the slot sites we recommend – whether new or established – offer a top-rated experience.

We add new slots sites to our list of recommended brands all the time, but only once they have been subject to our stringent review process.

Here's our latest list of new slot sites for you to check out.

Online Slots Sites Are Safe and Secure

Here at Find My Casino, we are passionate about helping you find the best slot sites for you, and we only recommend brands that meet our incredibly high standards.

Each slot site must hold a licence from the UK Gambling Commission, and many of our recommended sites hold additional permits from regulators in Malta, Gibraltar, the Isle of Man, etc.

When playing at one of our recommended brands, you can be certain that the operator is reputable and trustworthy, that your money is properly protected, and that games and outcomes are fair.

Online slots sites and slot games use random number generators to determine the outcome of every spin. The Gambling Commission requires RNGs be regularly tested by independent third parties.

This means that online slots sites and slot games cannot be rigged.

In addition to this, slot sites use SSL encryptions and powerful firewalls to ensure that your personal information and all financial transactions are safe and secure.
