How do We Rate Best Online Slots?

One of the best UK slots

In order to be able to rate online slots and ultimately decide which slot games we love the most, we use a set of criteria. Just as when we review the top UK online casinos.

We use these criteria upon writing our infamous slot reviews and of course, use our knowledge and expertise when we play online slots on stream. Does it give us an edge over the online casino?

A little bit as we make sure to play slots with a good RTP. But most of all, we get more fun out of playing the best UK online slots!

  • Return to Player Rate (RTP) – Describes the percentage of wagered money a slot machine pays back to players in the long haul. The best online slots UK have RTP rates of 95% to 99%. 
  • Betting Features – Pay lines, limits, adjustable coin sizes, automated betting, and the number of reels all contribute toward defining a great slot. Ideally, the best online slots combine these features seamlessly to suit the needs of different players.
  • Bonuses and Multipliers – Generous slots tend to have multiple bonus symbols that appear frequently. Multipliers, extra spins, bonus spins, you name it!
  • Splendid Visuals and Sounds – Top online slots have a mix of appealing visuals and attractive soundtracks. This can vary by game and the actual game developer a lot.
  • Unique Theme/Storyline – Today’s online slots come with fully-developed stories based on sports, movies, video games, and TV shows.
    Against that backdrop, a good slot machine could immerse you into the world of football and let you simulate a game as you chase goals, clean sheets and real-money wins. Casinos know this and so does the really skilled online slot developers.

Online Slots Review

At Fruity Slots we’re passionate about all things with reels, which is why we’ve got a dedicated editorial team to keep an eye on the upcoming releases. 

We get access to a lot of slots before they’re even released, so you can read our slot reviews to get an idea on the next best slots website and the next best slots UK. 

Our reviews have 3 stages, Teaser, Preview and Review, but what is each stage? 

  • Teaser – Early word from the provider about an upcoming slot. At this point we’ll have no info except for the name of the slot and perhaps an image. Although there’s not much to go on, you can definitely get excited if you see a new upcoming slot from your favourite provider
  • Preview – At this stage we might have a fair bit of information, but we haven’t actually played the slot ourselves yet. We don’t think it’s fair to rate a game before we’ve tried it, so at this stage we’ll fill you in with as much information as possible before we try the slot ourselves
  • Review – A full review! At this stage we’ve tried the game and we’ve collated our thoughts into a full verdict and score. We’re not perfect, and unfortunately we can’t put the slot through millions of spins so our opinion is still subject to change at a later date via our own experience or because of community experiences.  

Top Slots of 2023

You might be wondering what the top slots of 2023 is, but hold your horses because the releases are coming thick and fast. 

The release schedule for some providers is absolutely non stop with new titles every week or so, while others prefer to take their time with a release every month or so. 

There have been some dynamite releases this year, but we suspect that the best is yet to come. 

Did you know that we host annual slot awards? Every year we open up the polls to players who can vote on Slot of the Year, and other things too like Provider of the Year, Soundtrack of the Year or Most Innovative Slot.

Our Fruity Slot Awards in 2021 saw Nolimit City absolutely clean house with a winner in each of our categories, and we’ve a feeling that they could do the same again this year. 

So far, Nolimit City have released some bangers like Tombstone RIP, True Grit, Misery Mining and more. 

Keep an eye on our page and youtube channel for more awards in 2023. We always make it fun with community interaction, live streams and slot battles that are directly influenced by your votes! 

Our Expertise in Online Slots

It’s true. Anybody can play online slots in the UK and offer advice about them. However, not everyone plays these games weekly to analyze them from an expert point of view. That’s where our slots streaming experience comes into play.

Not only do we spend multiple hours of streaming slots on YouTube weekly, but we also identify the very best online slot games and online casinos to play.

We do it in front of thousands of viewers on stream and with real money. Obviously we get good amounts of bonus funds as we’re considered high rollers at the casinos.

Why not tune in and watch us play some of the top slot games next time? Below is a teaser of what can happen when we play slots online!

Different Types of Online UK Slots

UK online slots come in many types, from classic three-reel machines to today’s 5-7 video slots. Below are some of them:

classic online slotsClassic online slots

Armed with three reels, classic slot machines were based on the original slot invented in 1895. They feature a few symbols that you match on the top, middle or bottom row to win.

Volatility Mostly High
Features None
Reels 3
Best Casino 21 Prive

Video slotsVideo Slots

In addition to five reels, video slots have more advanced graphics, more pay lines and higher rewards. They also feature high RTP rates and unique themes. Plenty of unique features!

Volatility Low To High
Features Yes
Reels 5
Best Casino Video Slots

jackpot slotsJackpot Slots

These games feature a jackpot that increases daily until someone wins it. They work by taking a small cut from every bet made and then adding it to the grand prize. Expect pretty long odds

Volatility Mostly High
Features Yes
Reels 3-5
Best Casino Mr Vegas

 online slots with MegawaysMegaways slots

Invented in 2016, Megaways are new types of games from Australia-based Big Time Gaming. They feature 5-7 reels and have as many as 117,649 ways to win. You heard that right.

These slot games give you thousands of ways to win. Find the best Megaways slots!

3D slots3D Slots

3D slots feature the realistic imagery of today’s video games with the exciting betting features of slot machines.

As such, they have features through which symbols like fruits and bars appear to leap out of the devices for a more exciting experience.

Difference Between Low vs High Volatile Slots

The beauty of playing online slots UK is that you can choose games based on how frequently they payout. In casino terms, a game’s payout frequency is called volatility or variance. 

Low Volatile Slots

Low volatile slot machines payout frequently but in small amounts. These online slots are the best to play to get as much playtime as possible, but also to beat the wagering requirements on bonus funds.

If you deposit 10 pounds and receive free spins bonus that you’ll eventually need to wager, make sure to do that on a low volatile slot machine. Common with these online slots is also low betting limits and high RTP rates.

Best Low Volatile Slots RTP
Thunderstruck 2 96.65%
Starburst 96.10%
Blood Suckers 2 96.51%

High Volatile Slots

High variance slots pay up in decent or significantly high amounts but sparingly. That means you might have to spin their reels dozens of times before you win. But when you do, it’s an amount to be proud of.

These online slot games are known for massive bonus wins and best slots sites offer a great variety of these big bets slots. Pretty much “go big or go home” games.

Best High Volatile Slots RTP
Book of Dead 96.21%
Raging Rhino 96.18%
Dead Or Alive 96.82%
Bonanza 96.00%

As you can see, it’s all about preferences. Both types do have pros and disadvantages and of course, there are mid volatile slots as well.

At the end of the day, it’s all about entertainment and excitement rather than payline.

However, we wouldn’t recommend new players to start of with high volatile slots games as even the top slots in that category might eat up your bankroll in a few minutes.

Best UK Online Slots

The Best UK Slots are the same as slots elsewhere within the igaming world…or are they? 

It’s true that we see a lot of the same slots as countries that are governed by the Malta Gaming Authority, but did you know that sometimes you’re playing a different version? 

The Best UK Slots aren’t so different from the ones you’ll see European streamers play, except that their version may have a bonus buy option, or even a different RTP. 

Slot providers have to tweak their game depending on the market they’re working with. Sometimes these providers are releasing a game across multiple markets, but different laws can result in different version of the same game. 

This is best evidenced by the games that German players get. In Germany, there is no bonus buy, a maximum stake of €1, and you have to wait 5 seconds between spins. 

As a result of the maximum stake cap, providers have had to dramatically lower the RTP for german releases in order to remain profitable. 

But that doesn’t exactly answer the question of what the best UK slots are. Simply put, the best UK slots are, in our opinion, those with high RTP values, big win potential and plenty of features. 

An ideal online slot machine looks different to different people. Some people prefer a best slots website with low volatility games and low win potential to be safer, but some prefer the top slots with the biggest win potential. 

The choice is ultimately up to you, but we can certainly guide you along the way if you’re just not sure.

Mobile Slots Experience  

If you are like an average Briton, you spend 24 hours on your smartphone every week. And if your work involves using a computer, you spend up to 40 hours online. In light of these statistics, game developers have designed the slot games to run seamlessly on all mobile devices.

Whether you use an iPad or an iPhone, the Samsung Galaxy S10, or a cheaper Android smartphone, you can play online slots the UK conveniently. But what’s the experience like?

Same or Better Experience on Desktop?

Contrary to popular belief, mobile slots have all the features their desktop counterparts have. They feature stunning graphics, adjustable betting features, gripping storylines, and sensational soundtracks.

That means a good mobile slot creates the same hair-raising experience as the best slot machines on the desktop. Similarly, a boring game will have the same impact whether you play it on your smartphone or Mac computer.

Every UK gambling site is going in the same direction, to become mobile-first for its players.

High Payout Slot = More Fun?

In many cases, high payout slots provide more fun than low paying games. However, some players often skip high RTP games to play low-paying classic games to reinvigorate old memories. Again, others opt for average-paying games just because they have a mega jackpot.

Best Slots UK do offer great payout rates and thrilling bonus games. Every slots player wants to hit a big win now and then, so slot payouts do matter!

And you have a way higher chance of winning from a high payout slot machine. The big slots casinos such as Video slots will all include the best RTP slots by the best software providers.

Back to the fun factor, best payout online casinos tend to and the slots they offer do incorporate a myriad of features that make them exciting. For example, Gonzo’s Quest has a cascading reels’ feature that triggers winning symbols continuously. It also features multipliers that magnify your profits during bonus rounds.

Casino bonuses aside, high payout slots have storylines that spice up their gameplay and every British casino should have them available.

So which online slots payout the most?

High Payout Slot RTP
Ugga Bugga 99.07%
Mega Joker 99%
Rainbow Riches 98%
Ooh Aah Dracula 99%
1429 Uncharted Seas 98.60%
Jackpot 6000 98.86%

Are Online Slots the Most Played Casino Games in the UK?

Yes, online slots rule the UK’s remote gambling world. To put that into context, they makeup 65% of all casino games played in Britain and generate over £1.7 billion in revenue annually.

To expound on their dominance, below is an outlook of how popular different casino games are in the UK:

Most played casino games UK chart

Unsurprisingly, online slots are the most popular games on most online and land-based casinos worldwide. The only place where slots aren’t the most popular games in casinos is in Macau, where baccarat is the primary money maker.

New customers might also experience the massive hype around slots after making their first deposit.

Online casinos will always highlight their most popular and best slots online.

That is also the real reason why new players nearly almost get free spins together with the first deposit of a minimum of 10 pounds. It’s all about getting you hooked on a slot game.

7 Things you Need to Know About Online Slots

online slot games UK

As mentioned earlier, the beauty of slots is that they come in all sizes and shapes. However, you might want to keep these facts about them in mind:

1. Volatility determines how frequently you win

We touched on this fact earlier. When choosing an online slot, decide whether or not you want to win money regularly but in small amounts or sparingly but in decent amounts.

Both types of games have their pros and cons, so choose judiciously and based on your preferences. Keep in mind that the RTP is always theoretical!

2. They Payout rate varies

This is the reason why checking a online slot RTP is essential. You want to know if it pays well before you risk your money on it.

In the online casino space, the best slots have an RTP of 95% and all the way up to and 99%. These are the slot games you should target.

Scroll a bit further up for the slot machines with the best return that we’ve found.

3. Slots Bonuses Have Terms and Conditions

When you get an invite to claim free spins or money to bet on slots, read the terms and conditions first.

Crucially, look at the wagering requirements, minimum deposit, the maximum cash out limit, validity period, and contribution games. Of course, pick bonuses with the most favourable terms.

4. Slot Outcomes are 100% Random

No matter what anyone says, you can’t manipulate the outcome of modern slot machines.

They have robustly programmed software that produces winners randomly. As a result, no amount of experience can help you skew the results of slot machines.

5. Slots Hide their Best Rewards in Bonus Rounds

Pretty much every online slot have two rounds: the base game and the bonus round.

Logically, you begin by playing the base game. However, triggering a bonus feature takes you to the bonus round where you stand to win the best money rewards.

6. Some Slot Developers are Better than Others

When it comes to payouts and fun features, the software provider matters immensely.

That’s why many experts advise that you pick games from top-rated software creators like Netent, Microgaming, Play’n GO, Nolimit City and Quickspin

7. They Can Payout Incredibly High Amounts

When we say slots are the most popular casino games, it’s not just because they have beautiful graphics and are easy to play. These slot machines payout incredibly.

Progressive jackpots, in particular, payout up to £20 million. So, on your lucky day, you could win a life-changing amount of money from a slot.

8. Some slots are easy to bonus

Easy to bonus slots is almost a topic by itself as we noticed in our streams that UK players are asking about this slot type more frequently.

Anyway, yes there are some slot games that are more easy to bonus than others. They are usually low volatile and come with high return to player rate.

Join and Play a Slot Tournament

You might have seen us play slot tournaments on stream. These tournaments are one of the best features an online casino can offer its players. Usually, a casino brings multiple players together to compete on winning the most amount of points/money within a specific amount of time.

Players are asked to deposit a certain amount of money in order to be able to compete, usually £20 min.

Some slot casinos have tournaments whereby players compete with the money that they’ve already accumulated in their player’s accounts. The competitions can take hours, days or weeks.

However, the winner is whoever accrues the biggest winnings of points/money over that period. New customers might find these slot tournaments thrilling and the winnings are completely wagering free. Ready to join a tournament?
