Top 10 Best Online Slots 2023

As in previous years, I wanted to write some articles to answer the questions our readers ask the most. And while trying to decide which frequently asked question to answer first, it hit me that the top two have pretty much the same answer. The top two questions from our readers are: “What are the best slot machines to play?” and “What is the best online casino for slots?”. And in a way, they have the same answer.

That’s because rather than go by my opinion, I decided to trust you, the players. And it just so happens that the top 10 most played slots by UK players in 2023 are also among the best online slots to play.

At LadyLucks, we work hard to build relationships with our best-rated casinos to access exclusive information. And this year, the top UK online casinos and game providers let us take a look at the statistics of their most played slots in 2023. We’ve also selected the best casino offers to play each of these slots, and you can claim a welcome bonus offer when you click the Go To Casino button.

All these casinos are licensed by the UK Gambling Commission.

One thing that stood out to us is that all of these games are tried and true, and even long-time classics. All of these slots are mobile-friendly.

And my favourite thing about this list? That’s easy: the variety —there’s something for everyone!

You can play these lots for free by going to our review and clicking the Play Demo Mode button.

What are the best UK online slots to play in 2023?

10. Money Train 3 – 96.1% – High Volatility

Money Train 3 logo
  • Supplier: Relax Gaming
  • RTP: 96.1%
  • Volatility: High
  • Paylines: 40
  • Feature: Hold and Spin

The Money Train series is a real gem, let me tell you! What sets it apart is the incredible sense of progression it brings to the table. The first Money Train slot had the classic Wild West vibe, cowboys and all. Then came Money Train 2, where the excitement was kicked up a notch with a hint of Steampunk flavour.

But brace yourselves, because Money Train 3 takes it to a whole new level of high-tech horror! The evolution of these games is mind-blowing, and seeing what Relax Gaming has in store is like riding a rollercoaster of anticipation!

They’ve introduced some new symbols, added some new features to keep you on your toes and prepare for some serious Money Train destruction if you play your cards right. It all comes down to finding the right symbols, and let me tell you, when it happens, it’s like fireworks on the 4th of July. It’s simply breathtaking!

So buckle up, my friend, because this slot is going to take you on a journey of a lifetime!

9. Disturbed – 96.10% – High Volatility

  • Supplier: Nolimit City
  • RTP: 96.10%
  • Volatility: High
  • Paylines: 256
  • Feature: Free spins

Nolimit City is definitely pushing the boundaries with their latest creation, Disturbed. They’ve never been ones to shy away from controversial themes like blood, cannibalism, or even sadistic doctors. It’s like they’re constantly trying to shock and surprise their audience.

Disturbed lives up to its name, no doubt. The game is wrapped up in a strange package that will make you question whether to laugh or be concerned. But hey, Nolimit City fans are used to this level of shock by now.

But Disturbed also brings some innovation to the table. Nolimit City has taken familiar elements and packaged them in a fresh way. It may not be groundbreaking by their standards, but it’s still a unique offering.

So buckle up, give it a whirl, and see if it tickles your fancy. Just be prepared for a wild ride that’s unlike anything you’ve experienced before.

8. Holy Hand Grenade – 96.45% – High Volatility

Holy Hand Grenade logo
  • Supplier: Print Studios
  • RTP: 96.45%
  • Volatility: High
  • Paylines: 26-52
  • Feature: Free spins

Released this year, I’m betting that Holy Hand Grenade is one of the best online slots of 2023!

Holy Hand Grenade from Print Studios? Talk about a game that came out of nowhere and blew everyone away! These guys sure know how to think outside the box and take players on an epic adventure that’s like a breath of fresh air for the imagination. They’re all about showing you things you’ve never seen before and hooking you with gameplay that’s downright irresistible.

Now, I won’t lie to you, this game is not for the faint of heart. It’s got a real bite to it, so if you’re up for a challenge, this could be your perfect match. But let me tell you Holy Hand Grenade brings a whole new level of entertainment to the table. Whether you’re into laid-back experiences or ones that keep you on the edge of your seat, this game’s got something for everyone.

Give it a whirl and see what it dishes out. It’s like taking a wild roller coaster ride through a carnival of surprises. You never know what’s around the corner, but that’s part of the thrill, right? Holy Hand Grenade will have you grinning from ear to ear or holding your breath in suspense.

7. Ted Megaways – 96.03% – High Volatility

Ted Megaways logo
  • Supplier: Blueprint Gaming
  • RTP: 96.03%
  • Volatility: High
  • Paylines: 117,649
  • Feature: Megaways

After a first slot machine adaptation of the movie Ted, Blueprint Gaming has returned in 2021 with a new version: Ted Megaways. If you’re not familiar, this hugely successful comedy tells the story of John Bennet, whose wish that his teddy bear could talk to him is granted as a child. So it’s Ted on the screen, sitting on the left side of the screen with a beer in his hand in a green room or coming in with a zap gun.

Throughout the game, you’ll hear him throwing antics and having bad manners, just like in the movie. He even talks about marijuana. The game has a simplified design and is set to a background of lounge jazz that resembles the theme song of the American series “It’s Always Sunny in Philadelphia”.

The two slots have many similarities, but they also have some striking differences. The original offers a richer experience, with more features and a slightly more Ted-like atmosphere. The bear is more influential, with more dialogue and animation.

The Megaways version, on the other hand, is simpler, more logical, and still has a huge earning potential. In the end, both options are as pleasant as the softness of the fur and have been designed to satisfy different playing moods.

6. Mega Moolah – 88.12% – High Volatility

Mega Moolah
  • Supplier: Microgaming
  • RTP: 88.12%
  • Volatility: High
  • Paylines: 25
  • Feature: Free spins

The jungle themed Mega Moolah has been making the list of most popular online and mobile slot games since its release in 2006. Right away, Mega Moolah charmed us with its loveable animal symbols, the free spins and, of course, the insane progressive jackpot.

For a game with a low RTP, Mega Moolah has never ceased to draw players to it. It may be partly because the minimum bet of £0.01 does a lot to make the high-volatility a less intimidating risk. Although, in my opinion, there’s something else going on… Let’s not forget that Mega Moolah has a history of such huge payouts, that in 2015 it broke a world record for highest payout in online slot game history.

In 2021, 6 jackpots were won for a total of over £45 million! And this past year brought a new record jackpot of £16,247,967, shortly after the 100th Mega Moolah jackpot winner! A year that will remain forever engraved in the history of this slot!

Now that you know this, don’t be afraid to click the link below and take it for a spin!

5. Chocolates – 96.6% – High Volatility

Chocolates slot
  • Supplier: Big Time Gaming
  • RTP: 96.6%
  • Volatility: High
  • Paylines: Up to 65,536
  • Feature: Free spins

Chocolates, the sibling of the popular Donuts game, offers an experience that will resonate with players familiar with its predecessor. These two highly volatile games share similar advantages and disadvantages.

While the basic game may seem mundane, the real excitement lies in the potential for massive wins outside of the bonus round, thanks to the presence of x6 wilds. These wilds are the key to unlocking big rewards, and the anticipation of winning big on any given spin adds to the excitement.

In many ways, Chocolates is precisely the slot that Big Time Gaming fans have been waiting for. It’s a delicious appetizer to be enjoyed between the studio’s more experimental games.

As many of you already know, Donuts has become a phenomenal success for the studio, and Chocolates is set to follow suit. With just the right amount of improvements and additions, it perfectly caters to fans of the original game, striking the balance between extravagance and disappointment.

For those looking for a slot with a more intense and challenging experience, Chocolates is the perfect choice. The game can reach new heights when perfect combinations fall into place, offering the possibility of winning up to 65,536 times the bet on a single spin.

Overall, this is a great alternative, although it doesn’t deviate much from what Donuts already offers.

4. Gonzo’s Quest – 95.97% – Medium-high Volatility

Gonzo's Quest slot
  • Supplier: Netent
  • RTP: 95.97%
  • Volatility: Medium-high
  • Paylines: 20
  • Feature: Avalanche & Free Falls Spins

Gonzo’s Quest has a lot more to do with the legend of Eldorado today than it did when it was first released in 2011. And that’s because, as all legends must, it stands the test of time. Netent has a lot to thank Gonzo for.

I’m sure I’m not the only one who keeps coming back to the deep jungles of South America to keep seeing that little guy whose funny antics are already familiar to all of us. Gonzo’s Quest has a lot going for it in terms of sheer entertainment.

In fact, there’s so much packed into just one game (and so much has happened since it first came out!) that it’s easy to forget that Gonzo’s Quest was the first video slot game to replace the traditional spinning reels with the now iconic avalanche feature.

For those of you who like this style of gameplay but have never played Gonzo’s Quest before, I suggest you give it a try not just to enjoy the game, but also for the fun of meeting Gonzo. Those of you who are already familiar with him know what I’m talking about!

3. Book of Dead – 96.21% – High Volatility

Book of Dead slot
  • Supplier: Play’n GO
  • RTP: 96.21%
  • Volatility: High
  • Paylines: 10
  • Feature: Gamble mini-game

You have probably heard of the Egypt themed slot, Book of Dead, which has a lot going for it. From the outstanding artwork and soundtrack that take you exploring deep into the Egyptian temple, to its simple yet exciting gameplay.

Both Rich Wilde and the entire Book of Dead series have become so popular that it’s easy to forget that the game started out as a Book of Ra clone. In fact, many players think that Book of Dead has outdone the original, and it’s hard to argue with them.

And let’s not forget that one of its main features is the gamble mini-game. If you’re into the high-risk of double-or-nothing stakes, you won’t regret giving this game a try.

2. Bonanza Megaways – 96% – High Volatility

Bonanza slot
  • Supplier: Big Time Gaming
  • RTP: 96%
  • Volatility: High
  • Paylines: up to 117,649
  • Feature: Megaways™, free spins, Win Reactions

Bonanza is by far the most successful Megaways™ slot. In fact, it’s arguably the title that pushed Megaways™ into a fully franchised mechanic, with Big Time Gaming licensing it to other developers. Everything about this game is intense: the high-stakes, the fast-paced music, and the fast-moving symbols in the background.

Of course, this was when we were all still trying to become familiar with Megaways™, and some players found it too confusing. And to be fair, a 117,649 payline slot was beyond groundbreaking back in 2016. But it’s a testament to Big Time Gaming’s innovation that Bonanza Megaways™ has topped the lists for best slots and most popular slots every year since.

It’s easy to see how Bonanza did a lot to help Megaways™ become recognised as the biggest innovation in slot mechanics in recent memory. To this day, I am still amazed at the way that every time you spin, a random reel modifier changes the number of symbols that appear on each reel.

1. Starburst – 96.09% – Low Volatility

Starburst slot
  • Supplier: Netent
  • RTP: 96.09%
  • Volatility: Low
  • Paylines: 10
  • Feature: Re-spins

Starburst fits the definition of a classic in the broadest sense of the word. Its jewel theme is iconic, and the low-volatility mechanics are straightforward. Aside from being fun and easy to play, it has great graphics and fun dynamics that highlight both the simplicity and the high quality of its design. It has aged so well since its launch in 2011 because it has every element you expect a slot game to have: classic paylines with an innovative Win Both Ways feature, Wilds and re-spins.

If there is a downside to Starburst, is that it lacks the now-popular features that hadn’t been developed when it first game out. Veteran players know what I’m talking about when I say that no matter how many complex games you’ve played, you’ll always have time to come back to Starburst.

And newcomers will find it an approachable game to start discovering the world of mobile slots. Perhaps that, more than anything, is the key to its long-lasting success.

Best slots 2020

Wrap-up: Best online slots UK 2023

There’s a reason why this list still doesn’t include only new online slot games. Starburst, Bonanza, Book of Dead, Gonzo’s Quest and Mega Moolah are all tried and tested slots that we love coming back to, no matter what novelties we try along the way.

This list also gives us a glimpse into what UK players prefer in their slot games.

For starters, there’s an appreciation of variety evidenced by the range of games. The variety means that it’s hard to draw conclusions about preferences with regards to chances of winning, game type (e.g., video slot vs. 3D slot) and bonus games.

One thing that seems obvious is that everyone likes jackpot slots!

We can also see that high return-to-player doesn’t seem to be a huge concern for players. Mega Moolah’s official RTP is just over 84%, and the top four of these games have an average RTP around 96%.

So regardless of whether you’re a long-time fan or you’re about to click one of the links to try them out, I’m sure you’re going to spend quite a bit of 2023 playing these games. They’re not the newest, but they remain the most popular online slot games for more than one reason. We’ll leave it up to you to decide which of them are the best online slots.

This list will be regularly updated, so make sure to come back soon for more top slot games!

Stay tuned for our upcoming articles on the best new games to play in 2023 and the best paying slots for 2023!
