Best Online Slots Sites of 2022 | UK List

Author: Ioana Nutulescu
Reviewer: Tudor Turiceanu

We bring you a top-quality list of slot sites available in the United Kingdom. Hundreds of hours of our work bring you hundreds of vetted casinos!

How we test & rate?

Read more

Every UK slot site you see here has been tested with two main focuses. 

Full review

Our reviews have multiple parts and thousands of words each. This length and level of detail are because we want to check all the essential aspects.

  1. We look at the licencing to have a base layer of safety, security, and player fairness.
  2. We count the games and the game providers to see how much variety you have as a member. Then we see how they are grouped, detailed, and how easy it is to navigate the lobby.
  3. We use the bonuses and finish playing them. As such, we can assess if the terms conform to the player experience and how likely you are to cash out.
  4. Each review implies that we use at least 4 different payment services when permitted by the casino, 2 to deposit and 2 to withdraw. Thus, we can tell you what we recommend to protect your payroll.

Slot features

We know the games entirely, including what features mean and how they affect your play. We test them for every game like this:

  1. RTP – How much will the game deliver on a long time of continuous play
  2. Volatility – How likely the pot results may change dramatically
  3. Paylines – How many winning combinations the game embed
  4. Bet limits – Can your budget fit the average gameplay?
  5. User experience – Are there any glitches that can annoy you?

How do we test online slot sites?

How do we test online slot sites

Transparency is a key part of our review process. To stay true to ourselves, we present in detail how we work for UK players.

The UKGC mainly focuses on:

  • Providing responsible tools
  • Pre-empting minor gambling
  • Offering an overall reliable experience
  • General prerequisites for safe play at a casino.

Step 1: It all starts with a valid licence

Step 1 It all starts with a valid licence

The United Kingdom Gambling Commission guarantees the UK slot sites follow strict legislation. The terms are fair, the games are not pressuring you to play too fast, you have access to responsible tools, and your overall time spent there is positive.

Tips

The United Kingdom Gambling Commission always prevents minors from gambling. Thus, your children will be protected too.

Most top online casinos with a UKGC licence are also vetted by independent third-party auditors.

We will look for online slots sites in 2022 that have seals from:

  • eCOGRA
  • Gaming Labs
  • iTechLabs

Those add a layer of safety regarding the software and engineering of the games we have no way of testing ourselves.

Step 2. We check the RTP of slots sites

Step 2. We check the RTP of slots sites

RTPs are essential if you want to choose a site and stick to it long-term. It is a theoretical percentage that calculates your returns over 10000 rounds or even more.

That means that when it comes to short-term play, it may not change your experience that much.

Each slot game is released by the provider with an initial rate. However, online casinos can change it when they partner with the game provider.

Tips

Our mission is to check the average RTP for each casino and show it to you in our analysis, so you know the difference from theory to practice and from one casino to another.

Step 3. We dig deeper into the volatility of slots

Step 3 We dig deeper into the volatility of slots

Slot game volatility means the likelihood of the result of a spin to be widely different each time.

There are two volatility phases:

  • Low volatility – the game payout is the same range almost all the time, and the sums are never too high as compared to your bet
  • High volatility – the game payout may be significantly higher than the bet, even if the bet was quite insignificant

We can check that by going in the game’s settings. In the rare cases when that is not public in the open game, we test it for two weeks and make our own assessment.

Step 4. We never miss looking at the paylines

Step 4. We never miss looking at the paylines

Paylines are the embedded winning combinations that, when hit, will result in a winning bet.

The number of paylines must always be written in the game settings. Sometimes, the original number may be expanded in certain conditions, which fall in the special features category.

Recommendation

The number of paylines does not correlate with the game’s popularity. Some of the most popular slots in the UK have just 20 or 25 paylines.

Step 5. We analyse the unique features of the UK slot sites

Step 5. We analyse the unique features of the UK slot sites

Since there are thousands of games created yearly, the best ones need to have catchy features. We analyse them and tell you which feature is the best.

Here are the main ones:

  • Multipliers – the number of times your bet result will be multiplied randomly
  • Wilds – random symbols that appear and expand your bet
  • Scatters – random symbols that create a payline where it wasn’t

Step 6. We proceed with making bets

Step 6. We proceed with making bets

All of the settings and details are tested by us with real funds. That is the same method you would use when playing, and we need to make the same steps you do so we can be your trusted guide.

Step 7. Overall user experience on mobile & other devices

Step 7. Overall user experience on mobile & other devices

Between 80% and 90% of online gambling is nowadays done on mobile phones and sometimes mobile tablets.

Thus, we focus on those types of devices a lot when we test the best online slot sites. We can then see if there are glitches and how they might affect your sessions.

Why do we use all these testing methods?

We want to bring you the best gambling services that we confirm to be good first. We need hand-down testing, methods that are available to you and bring you the safest options.

Important

We use objective testing and a team system to remove bias on any opinions we might have.

Advice for safe jackpot play

Advice for safe jackpot play

  1. The probability that you win the jackpot is tiny. That is backed up by the lower RTP rate and how often the jackpot is won. So, don’t have any high hopes.
  2. As a new player or a player that plays on a tight budget, limit your sessions to under 15 minutes a day.
  3. There is a small percentage of casino bonuses based on them.
  4. Progressive jackpots have lower chances of winning as compared to a classic lottery ticket.

What are the best online slots to play?

  • Starburst
  • 9 Masks of Fire
  • Book of Dead
  • Book of Ra
  • Immortal Romance
  • Wolf Gold
  • Gonzo’s Quest
  • Fire Joker
  • And essentially any game that you like, as long as you exercise caution with your time and money.

Top game providers

Game provider Best slot features Most popular game Other perks
Microgaming Cluster plays Mega Moolah VR games developed
NetEnt Avalanche wins Starburst Lots of branded slot games
IGT +450 licences in different jurisdictions Cleopatra Landbased casinos
Big Time Gaming Megaways feature Bonanza Triple reaction feature that adds reels

Game providers shine the most when they are partnered with high-quality casinos. For example, some of the best casinos we have listed are top Microgaming online casinos or NetEnt casinos in the UK. They are SSL-locked, UKGC-licences, and independently reviewed sites with thousands of new users signing up daily.

While these are business-to-business collaborations of two separate entities, the best IGT casinos offer, besides their gaming palette, whitelabel solutions to online casino sites. Thus, all of the items in the category share certain similarities.

How to play slots online?

How to play slots online

Basic steps to slots play

Your first and most vital step is to know the game rules and what each symbol or feature does. That means you won’t have any surprises with the game’s functioning.

The second step is to make calculations to reach a fixed slot play budget. Once there, never exceed it.

Important

CasinoAlpha’s perfect budget formula is to first figure out your pocket money monthly, after bills, and your savings accounts. Out of that sum, 10% can be used for gambling. We highly recommend you don’t spend more than that.

The third is to choose a casino and a game. That’s where we help you with your decisions.

The fourth step is to read the game specifications and rules once you launch it. Then, you can just play.

How do online slots work?

They are software that is built on complex code. Their results are based on Random Numbered Generators, so there’s no room for rigged results.

What online slots pay real money?

All of the games on UK online casinos can pay out real money if you use real funds and hit a payline.

Tips

Real funds play in the UK is tied to confirming your account and finishing KYC to prove you are of legal age and your payment services are legitimately yours.

How to pick a UK slot site & sign up?

How to pick a UK slot site & sign up

  1. Use CasinoAlpha’s database which is updated monthly.
  2. Find a site with ratings above 3.5 stars out of 5 total.
  3. Read our review and bonus descriptions to get familiar with what they offer.
  4. Sign up using their instructions.
  5. Complete KYC as fast as possible so you waste less time while engaged in transactions.
  6. Play safely and respect the Terms and Conditions attached!

Bonuses compatible with slots

Bonus type Best feature Tips Find it here
Free rounds Budget-friendly Calculate the bonus value by multiplying the spin value by the number of spins received Free spins no deposit required
Payment-free bonuses Allows to explore without spending Use the necessary bonus code when required Free no deposit bonuses
Sign up offers Accesible with small deposits Choose bonuses that work on multiple deposits Welcome bonuses
No wagering needed Less time to cashout Use our listing to find them instead of looking for them yourself No wagering casinos

These are just a few subtypes of the best online casino bonuses that we work with daily. We know that each player can find a type that fits their needs.

Be aware

  1. Each bonus has unique terms and conditions attached. You need to stick to it and respect it, otherwise, you risk losing the bonus or the funds derived from it.
  2. Cashing out before finishing wagering, when the issue is present, is impossible and may result in you losing your bonus.

Recommendation

Take time between sessions and bonuses for your own mental health. Gambling excessively can turn you into a bonus hunter and have negative consequences.

Major types of slot games

Major types of slot games

Slot sites have a multi-faceted catalogue of options. We give you definitions for each major game type.

Real slot machines

These are the games found in top land-based casinos from the UK. They are activated manually through a button or an arm. Obviously, you can’t find them in online casinos, but they are the base source of the game we play today.

Classic slots

These are games that have a classic layout, usually with 3 rows and 5 reels. The paylines are between 10 and 25 at most, and the animations are minimalistic. They are meant to mimic the original games that were built almost a century ago.

Fruity slots

The symbols that fall and rearrange themselves are fruits, like cherries, watermelons, etc. Otherwise, the design is very much similar to classic slots. You will find symbols that represent the number 7, which is a stable symbol.

Videoslots

The animation, fades, music, and all the sensory elements are very modern and high-tech. There is no single theme associated, but the most encountered are adventure-based, historical, mythological, and fantasy designs.

Progressive

The pot that increases or decreases while you are playing can grow in size and value when you keep playing. In certain instances, the pot increases while players are betting on multiple platforms, like Mega Moolah, for instance. Jackpot slots are a synonym for the same concept.

Megaways slots

These are slots in which the winning paylines reach numbers that go way over 10000. This is a creation of Big Time Gaming and they have, naturally, gained a lot of traction in the UK online industry.

Jackpots

Jackpot slots are the ones where the pot increases continually and exponentially to the bets made by one or more players that are actively playing. The terms jackpot slots and progressive slots mean similar things and can be used interchangeably.

VR slots
