TOTAL SCORE

Leo Vegas may be the number one online casino in the UK, so it’s hardly surprising that their slots offering is of the highest quality.

If you’re hungry for slots, Leo Vegas will feed your appetite. With lots of three-reel and five-reel slots, there are over 600 titles to be played, including many big-name features, such as Book of Dead, Starburst, and Mega Fortune Dreams.

Slots users may be pleased to learn that the welcome bonus at Leo Vegas includes 50 free spins on the popular title Big Bass Splash. When you register for an account, you can also get up to £100 in bonus funds.

There’s zero question of safety or reliability, and Leo Vegas has been one of the most tried and trusted slots sites in the UK for over a decade now. It is licensed and regulated by the UK Gambling Commission.

Overall, in terms of what it offers players, Leo Vegas, which is available both on desktop and mobile, rates very highly indeed. However, there are a few minor drawbacks, one of which is the fact that there aren’t too many payment options, though both PayPal and Apple Pay feature, which is positive.

#2 – Casimba Slots UK Site

BONUS

100% Up To £200 on your first deposit + 50 Bonus Spins

70%
TOTAL SCORE

Established in 2017, Casimba is one of the newer online casinos in the UK, but it certainly doesn’t rank poorly as far as we’re concerned.

If slots are what you’re looking for, then you’ll be pleased with what you find at Casimba. With over 750 slots to enjoy, Casimba offers more variety than many of its competitors. The slots are easy to play, and the graphics are good, too, thanks to lots of high-quality software.

There are, of course, lots of minor and niche slots, but those looking for the big features won’t be disappointed, as you’ll find Big Wheel Bonus, Book of Dead, Gonzo’s Quest, Diamond Royale and Wild Portal, to name just a few.

Where Casimba beats the competition is the welcome bonus. New slots players who register for an account at Casimba will be rewarded with a 100% deposit bonus on their first deposit, up to a maximum of £200. In other words, deposit £200 when you first join and get £200 in bonus funds. Better yet, you’ll also receive 50 free spins.

There are a few other really nice touches from Casimba. Firstly, the live chat is available 24/7, so you don’t have to wait to get an answer to your query, even if it’s late at night.

Withdrawals are really fast too, with the vast majority of players reporting a withdrawal time of 24 hours or less. It is worth noting that there is a weekly withdrawal limit of £5,000 for UK players.

#3 – Plaza Royal UK Slots Site

BONUS

Up To £200 + 100 Extra Spins

80%
TOTAL SCORE

Plaza Royal, one of the newest UK casino sites, has only established itself in 2020, but don’t think for a second that it has little to offer.

On our overall list of UK Online Casinos, Plaza Royal ranks third, and there’s good reason for that.

The welcome bonus is great for starters, with new players getting up to £200 in bonus funds, while slots players will be encouraged to see that you also get 100 free spins when you sign up. This is double the industry norm of 50 free spins.

There’s plenty of table action to get stuck into, while the live casino options are good too, but if slots are your thing, then there’s certainly enough to keep you entertained. Plaza Royal has tons of slots, featuring three- and five-reel games. Popular titles include Golden Jokers, Buffalo Hold, Dynamite Strike, Book of Dead and Eye of Horus.

You know you’re playing with a safe site too, as Plaza Royal is fully licensed by the UK Gambling Commission.

If we have one criticism of Plaza Royal, then it is the fact that the live chat support doesn’t work 24 hours, though if you have a query during the chat isn’t available, you can direct it to support@Plazaroyal.com.

#4 – Videoslots UK Slots Site

BONUS

100% up to £200 Bonus

FREE SPINS BONUS

11 Welcome Spins

80%
TOTAL SCORE

Founded in 2011, Videoslots doesn’t necessarily have the big reputation of Leo Vegas or Betway Casino, but it is no longer a back number. In fact, this UK casino is one the best as far as we’re concerned, especially when it comes to slots.

If you seek variety from your online casino and slots provider, you’d be hard-pushed to find something with more options. There are over 7,000 titles to be found at Video Slots. All the big-name progressive slots, such as Classic Fruit, Lucky Diamonds, Cash Crazy and Double Whammy, can be played, as can many lesser-known slots. There are also casino and table games, such as blackjack and roulette.

The action doesn’t stop there, oh no. There are jackpots and scratch games, too, including titles such as Gold Rush, Diamond Rush and Happy Scratch.

The welcome bonus is quite appealing. When you register as a new player and join Video Slots, you’ll get a 100% deposit match up to £200, which is more than the industry norm and certainly one of the better welcome offers.

Licensed by both the Malta Gaming Authority and UK Gambling Commission, Video Slots are reliable and safe to use.

The plus points of Videoslots are many. There’s a massive selection of games, and a huge number of software providers, which helps with the variety, while they may be the king of slots, with many options.

The downside, however, is that the website is a little dated, and in that respect, they are behind some of their main competitors, though if you can get past that, you won’t find too much to complain about.

#5 – Betway Slots UK Site

BONUS

100% Match Bonus up to £50

80%
TOTAL SCORE

In the UK, Betway stands as one of the biggest betting brands of all. From sports betting to casino games and slots, Betway has it all.

With many slots and casino games, Betway Casino rates as one of the best UK slot sites. You may not find as many options as you would at Leo Vegas or Video Slots, but that doesn’t mean the options are lacking, and you’ll still find all the biggest and most popular titles.

The new-player bonus at Betway Casino is far from disappointing. In fact, if you’re signing up to try your luck on the slots, the welcome offer is a great way to boost your starting funds.

To take advantage of the welcome offer, all you need to do is register for an account, and Betway will give you a 100% deposit match up to a maximum of £50. If you deposit £50, you’ll get £50 in bonus funds. Likewise, if you deposit £25, you’ll get £25 in bonus funds.

One of the main reasons Betway Casino is so famous for slots is that it is easy to use, while both the desktop site and the mobile betting app feature slick designs. In truth, there aren’t any negatives for UK players.

What are online slots?

If you’ve ever been to a brick-and-mortar casino, you’ll know what a slot machine is. It is that little machine that you see flashing bright lights, sit in front of, and pull a lever hoping that the symbols will match up and you’ll become a winner. Online slots are the same, except you can use them from home on your PC or mobile.

While real-life slot machines often come with three reels, an online slot machine takes this further. The concept is the same, where you will spin the reels so the symbols match up, but you can add a ton more reals and other special additions, which can lead to bigger winnings.

How do online slots work?

To play on an online slot, you first need to sign up for an account on the online casino of your choice. Once done, you will need to make a deposit. This can be any amount under the casino’s maximum and should only be what you feel comfortable spending. After you have money in your account, you can play a fun and exciting online slot.

As mentioned, you’ll often find most physical slot machines with three reels. Online slot machines have the same but can also come with many more, depending on the game. To start a game, you must stake the pay lines from your deposit amount and then spin the reels. You will know you’ve won money when the symbols on the reel match up. It will often need a minimum of three matching symbols, but this can depend on the game.

Online slots have no logic or strategy, and you can’t do anything to ensure you win. If you’re playing at a trusted online casino, it will have a random number generator built into its system. Each outcome is entirely due to luck; there is no way to rig the game and ensure the symbols match up. It makes the game much more thrilling and is fair for every player on the site.

Online slots terminology

You may come across some specific words and terminology when playing online slots, and it is useful to know what they mean to get the most out of your gameplay. Below are some of the most common terms associated with online slots:

Blank

You’ll find a blank between your symbols when unsuccessful at winning.

Bonus

A bonus provides you with a special chance to increase your winnings. You may receive free spins or credit to your account to use on a game.

Coin size

The value of the bet you have placed on the online slot.

Credit meter

How much money or game credits you have left in your account to use on the online slot.

Jackpot

The most amount of money you can win from the online slot.

Paytable

The table shows all the potential winnings you can earn in a specific online slot game.

Payline

Your matching symbols need to land on a pay line so you can win.

Reels

The horizontal columns in the game display the symbols.

Scatter symbol

A scatter symbol can unlock a special bonus anywhere on the reels.

Myths about online slots

Just like with any online casino game, there are myths that you may have heard about playing online slots. However, we are here to debunk them, so you can play each game without any doubt or worry:

#1 – Online slots will pay more when there hasn’t been a big win in a while

It is untrue that you will more likely win more money from a slot when it hasn’t paid out in a while. Online slots have been designed to be entirely random, including every spin you make. You can either have a jackpot win back-to-back or no win at all. It is all down to the random number generator, and you can’t guarantee you will receive a win if there hasn’t been one for any player in a while.

#2 – You can never increase your chances of winning

While we have said there is no strategy for winning a slot machine, that is true. However, there is a way you can increase your chances of winning. You must select a slot from a provider that offers a higher return to player (RTP) value. You may not be able to win as large a jackpot as in other games, but you will more easily experience the thrill of seeing the symbols match up on the slot’s reels.

#3 – There are special times of day when you can win more

Just like with the jackpot myth, you can’t log on to online casinos at a certain time of the day and expect you’ll be able to win. Online casinos do not have the programming potential to select the payout percentages depending on what time it is, and even if they did, this would make the casino much less fair and trustworthy, which means they have a higher chance of being shut down.

Finding a reliable online slots site

Once you’re ready to start playing slots, you must find the perfect online casino. You want one that is reliable and fair, so you can follow these steps to ensure you’ll be getting the most out of your experience:

Look at reviews

The best way to tell whether an online casino is reliable is by looking at what other players have said about it. By searching for site reviews, you will see all you need to know about the casino and the online slots. Other players will say how good the payout time is and whether the games are fair.

Check it has a license

A reliable online casino will be licensed and registered with an authority. If the casino doesn’t have a license, you should avoid it at all costs. The licensing should be mentioned somewhere on the website, but it can be difficult to find, so your best option is to use Google or see what the reviews have said.

Choose quality over quantity

You may be drawn to the online casino that offers over 1,000 slots to play. However, don’t let this tempt you. Often, it is too good to be true, and they may not have great payouts or RTP rates. It is best to go for a trusted online casino with fewer quality slots than those offering everything.

Review banking options

Some banking options are more reliable than others, and you should only use an online casino that offers the deposit and withdrawal methods you are comfortable with. They are likely reliable if they have the typical debit and credit card options. However, you can also double-check these by looking back at the reviews.

Top 10 UK online slots

Once you’ve found the casino you want to use, it’s time to choose your first online slot to play! It can be daunting to find one, as tons are available, but we have made this process easier by listing the top 10 online slots you can find in the UK.

Starburst

Starburst slot

Wolf Gold

Wolves and gold – who doesn’t love both these things? And when you put them together, you get a thrilling slot from Pragmatic Play. Equipped with some exciting features, this five-reel game is making its way up the rankings and becoming one of the most played online slots in the UK. Each game has up to 25 betways, with a whopping maximum win of 5000x.

While playing the game and enjoying the unique theme and bright graphics, you will be able to receive your initial stakes multiplied by 5000 if you land on the matching symbols.

Age of the Gods: God of Storm

If you’re a fan of mythology and fantasy, then you will love playing this slot. It has everything you need to experience some magic from the comfort of your home in the UK. Players get to experience five reels and 25 pay lines, and after each spin, you’re in for the chance of winning up to £125,000. Could you imagine taking that home?

Like any other slot, there is a minimum and maximum bet. You must place at least £0.01 and can’t exceed £250. And like with the other top games mentioned in this list, there is a high RTP of 96.14%. Get ready to go into battle and experience some great themes, including Gods, castles, and weapons.

Big Bass Bonanza

Big Bass Bonanza may have only been released in 2021, but it has made a great name in the UK, placing it fifth on this list. It has unique features you won’t experience on any other slots, and there are some great bonuses to earn once you play this game for the first time. You can also pick up some scatter symbols for additional free spins and multipliers.

This online slot comes with four reels and 12 betways. You can also win up to 4000x your initial bet, which is a fantastic prize, even if you only place £1 down. You’ll undoubtedly be mesmerised by the bright colours and themes and never want to stop playing.

Crazy Time

It’s time to get crazy in Crazy Time! This online slot designed by the Evolution provider is a high-end game with some great features to get stuck into. The user-friendly interface makes navigating easy, even if you’ve never used an online slot. You’ll feel ready to win once you see the bright colours and hear the exciting music.

Crazy Time has many bonus rounds, making gameplay even more exciting, such as the coin flip and cash hunt. Whenever you get a bonus round, there is a higher chance of winning 25000x your initial stakes and a fantastic RTP of 95.5%. This game may not make you go crazy, but you’ll be crazy not to try it.

9 Pots of Gold

What’s better than one pot of gold? Nine of them! Designed by Gameburger Studios, this UK online slot is perfect when you have tried everything on this list and need something new to challenge you. It has only been around since 2020, but the Irish theme has made it stand out among the crowd and become a fan favourite.

You go on an adventure when you start spinning, and the adventure gets even more exciting with the prospect of winning 2000 times your bet. There is a minimum bet amount of £0.20, which is a little higher than most, but you can only place a maximum bet of £60. You can also increase your chances of winning with free spins, scatter symbols, and multipliers.

Gonzo’s Quest

Gonzo’s Quest by Megaways is loved by players in the UK and is a global slot that players cannot stop using. It has almost a record-breaking 117,649 pay lines and a pretty great RTP of 94.66%. Not only do you have fun with the opportunity to win money, but you can also experience a whole story as you go through the game.

The visuals and sounds enhance the excitement of this online slot, and there are unique little objects you wouldn’t find anywhere else. You cannot place a very high bet as the maximum stake has been placed at £4, but that isn’t to say you can’t go home with a lot if you win.

Fishin’ Frenzy

Released in 2014, Fishin’ Frenzy has been an online slot that the UK hasn’t gotten enough of. With low to medium volatility, it does come with a high RTP of 96.12%, which means you have a good chance of coming home with at least some winnings. You can win up to 50x your initial stake once you have placed a minimum bet of £0.01 or a maximum of £10.

This video slot has five reels and 10 pay lines to explore. You can easily win free spins rounds if you trigger one of the three scatter symbols of the wild. Reel Time Gaming has gone above and beyond in designing this game, and you certainly won’t be let down if you play it.

Rainbow Riches

Last but not least, you have Rainbow Riches. It comes with all the magic of searching at the end of the rainbow for your pot of gold, but you don’t have to leave your sofa to do it. It is one of the older online slots on this list since it was released in 2004, but that doesn’t mean it doesn’t come with its charms.

Once you open this slot, you’ll see five reels and 20 betways. However, the only downside to this slot is that it comes with a maximum win of £500. This may make things less thrilling, but it is the perfect game for people looking to start.
