What are themed slots?

All online slots are themed to some extent, but some have a more prominent topic, character or behind-the-scenes story that makes them stand out in the crowd. It might not always be the theme itself that makes the game tick, but it’s the packaging that draws players in to try the slot.

The theme is what sets the slot apart from other games and although they don’t always exceed the expectations, a slot without some sort of concept behind the gameplay is hard to spot these days. Therefore you see slots enriched with various topics including film, adventure, animals, space, fairy tale, you name it.

A nice problem to have with so many themed slots is that you are spoilt for choice. The issue with the choice is that slot developers may take on the challenge of copying popular thematic slots. This is why it seems that there are endless clones of the Book of Ra slots called the ‘Book of’ series everywhere you turn.

Why do people play themed slots?

The simple reason why players love themed slots is that they are either fans of a certain TV show, film or a band represented in the slot. Favourite superheroes or childhood cartoons are a big part of our memories and this extended virtual reality lets us see them again in a different form and maybe even be them in the game.

As a result, to utilise players’ emotions, game developers produce numerous themed titles to cater to as wide a range of players as possible. Let’s look at some of the most popular slot machine themes in 2024.

Most popular themed slots 2024

Pick out any theme and you’ll find an online slot machine based around it. From ancient Egypt, space aliens, fairy tales and spooky Halloween themes to Viking slots, there’s something for every player.

Most likely there isn’t a slot theme that hasn’t yet been covered. But do we really need another ‘Book of’ game slot or one more sequel to a blood-sucking vampire slot? There is no right or wrong answer to this question. As long as players enjoy these themes and are willing to play the game, it will be coming around again and again.

Here are our top 10 slot themes you should check out in 2024.

1. Ancient Egypt slots

Most popular slot themes - Ancient Egypt
There’s something magical, mystical and sinister at the same time about the old Kingdom of Egypt that draws players to these types of slots. There are countless games in the Egyptian themed slots category but new or updated versions keep coming year after year.

Ever since one of the most popular land-based machines, Book of Ra has been replicated by Novomatic, the ‘Book of’ series has been making the headlines non-stop. Following the first online version, the sequels Book of Ra Deluxe, Book of Ra Deluxe 6 and Book of Ra Magic are probably the best versions of the ‘The Book of’ theme from the above developer.

Then there’s the adventurous Book of Dead slot with Rich Wilde on a risky quest to find the hidden Pharaoh’s treasures. It’s been trending among gamers for quite some time.

The classic IGT slot game Cleopatra has been ranking highly among players since its release in 2012 and isn’t going anywhere any time soon. Again, it’s an online game reminiscent of a land-based casino that players can’t seem to let go.

2. Viking/Norse Mythology slots

The dark and cold Norse mythology themed slots have been on the rise for a good while. These types of games brought a breath of fresh and icy air into the slots world.

The North Storm from Rabcat is a good example. The graphics and soundtrack are spot-on here making it the perfect Viking themed slot. NetEnt’s Hall of Gods with three progressive jackpots on display is another favourite.

Let’s not forget the brilliant ‘Vikings Go’ slot series from Yggdrasil, the perfect game developer studio to make it happen. Inspired by Norse mythology, we can’t think of a better contender to create a bone-chilling Vikings go Wild, Vikings Go Berzerk, and Vikings go to Hell trilogy of slots.

3. Horror slots

Top three vampire slots
Vampires, undead creatures and other freak-show inspired slots have always captured players hearts and imagination. A lot of horror-themed slots are based on classic thriller films and dark stories landing their supernatural powers to these slots. Familiarity with these mythical creatures is what makes this theme such a popular slot category.

Among many, the ripper Dracula slot from NetEnt and Microgaming’s charming yet highly volatile Immortal Romance slot are the two of most relished vampire-slaying slots.

For heart-stopping action, based on a blood-curdling 1978 horror movie by John Carpenter, Halloween slot will get your heart pumping. With wandering reels and atmospheric backdrop, this horror-themed slot will spook you out, even on a bright sunny day.

4. Oriental slots

Looking upon a lighter side of slots themes, the Oriental theme occupies a big chunk of gaming space. Chinese-themed slots, although not appealing to every player, do well among Asian-themed games fans due to the mysticism and luck attached to the slots.

One of the best-rated games among players and experts alike is Chi, a unique Chinese-themed slot from ELK Studios whizz kids with a backstory of two helpful spirits, Chi and Mow.

Another Oriental-themed slot that had heaps of interest among online slot players since Aristocrat brought it to everyone’s fingertips is the fire-spitting 50 Dragons slot. It’s similar to 50 Lions slot by the developer and yet another successful replica of a land-based casino slot machine.

Another fast-emerging subcategory that’s becoming more and more popular among Oriental-themed slots are Japanese anime slots like Koi Princess. It features beautiful animations and complementing soundtrack, two of the many elements that define themed slots and attract slots players.

5. Movie slots

Let’s talk about movie-themed slots now. Over the years developers have dabbled in many different themes to bring players varied slots. But when they sensed a massive enthusiasm for branded slots, they latched onto them and never looked back.

And so we have the amazing movie-themed slots like Jurassic Park, Game of Thrones and the blockbuster Dark Knight Rises among many. All of which triumphed among movie-based slots enthusiasts.

Many players love movie-themed slots because they feature their favourite characters and soundtracks, some even have clips from the movie incorporated into gameplay. Often the fantasy combined with realistic graphics adds significantly to the thrills and draws players to this particular slot theme.

6. Music slots

Find out the top 6 rock slots and where to play them
Music is such a big part of our everyday life and it’s unsurprising to have slots themed around legendary bands. The great thing about these slots is, you guessed it right, the soundtracks blasting in the background.

The legendary Guns n Roses slot, for example, will rock you all the way to the 1,125x max payout while Motörhead by NetEnt will delight you with 114,000x your stake along with Lemmy’s rock tunes.

Following in the 1960s music artists’ footsteps, Jimi Hendrix prizes hit as big as his songs and that’s why this music-themed slot is a legend among many players. Turn up the volume or pop on your headphones if in public, and listen to Jimi jammin’ as you spin away.

7. Adventure slots

Best Adventure Slots
Slots with an adventure theme are some of the most-loved games at online casinos. When you play an adventure slot, you could be transported anywhere from a gold mine to a jungle. These slots are aptly names because they take you on an adventure through their graphics, soundtrack and features.

Some slot developers, such as Play’n Go, who have adventure heroes that take you on their journeys in more than one slot. Join Rich and Cat in their worldly travels in slots like Rich Wilde and the Tome of Madness and Cat Wilde and the Doom of Dead.

Adventure slots might take you back in time, into the future or to a completely different world that doesn’t exist! Gonzo’s Quest transports you to ancient Colombia and Treasure Skyland carries you off to a fantasy land. If you’re a player who’s always looking for adventure and to try something new, then this is your type of slot.

8. Alien and Space slots

Thanks to creative game developers, we have a chance to fly into space whenever we desire with the alien and space-themed slots. Outer space is full of secrets and discovering the unknown is what draws players to this theme.

If you’re after some action-packed space adventure, Aliens is NetEnt’s graphic masterpiece. In the stunning cluster pay Astro Legends slot you’ll be helping the shape-shifting Lyra beat the space monster, Erion. For a more classic slot approach, check out Playtech’s Space Invaders and shoot down the aliens to win big.

9. Fruit slots

The fruit slots need no introduction. They were and will always be a classic slot theme. For casino newbies, fruit slots can be a great intro into slots world and for pros, a laid-back gambling session.

Hot Chilli is one of those great fruit-themed slots to spice up your gambling experience. Simple in gameplay and yet full of surprises, the oriental fruit slot comes with medium-high volatility, multipliers and a tangy RTP of 96.52%.

With 60,000x your bet, a progressive multiplier and an extra lush RTP of 96.52% you don’t want to miss the Extra Juicy slot by Pragmatic Play. For something more unusual and quirky, try out Fruitoids by Yggdrasil with an excellent RTP of 96.70%.

10. Irish slots

The most popular slot themes - Irish slots
Fancy some Irish luck? Then spin some Irish themed slot machines. Slots revolving around Irish slot themes have always been seen among the favourites when it comes to choosing the best slot themes.

Whatever luck you believe, be it a four-leaf clover or a pot of gold at the end of the rainbow, Irish-themed slots are fun, colourful and enchanting.

Among untold numbers of Irish slots, we couldn’t get away without mentioning the all-time favourite Irish classic Rainbow Riches slot by the old-school Barcrest developer.

But if you’re looking for more up to date Leprechaun themed slots, try Rainbow Riches Pick n Mix by WMS. Otherwise, Finn’s Golden Tavern, the sequel to everyone’s beloved Finn and the Swirly Spins, is an excellent choice too.

The craziest themes in slots

Never mind the fierce Vikings, red-bearded leprechauns and juicy fruit slots. How about we list some of the craziest slot machine themes depicting aliens, unicorns with gun machines, grannies terrorising the city, and even, errr… bible slots?

Machine Gun Unicorn – Genesis This is an awfully weird slot with pickled zombie heads in jars as symbols and a unicorn with a machine gun sticking from his head. Good fun if you like high levels of weirdness in a slot game.
Cyrus the Virus – Yggdrasil Did you ever think you could have fun playing a germ-induced slot machine? It’s actually cutesy, but maybe grab a hand sanitising gel before playing.
You Lucky Bastard – Microgaming If you don’t mind being sworn at during gameplay, check out the old-school You Lucky Bastard slot by Microgaming.
Eggomatic – NetEnt Mechanical chickens in a conveyor-belt-driven egg factory. Is this the future we are heading to? If you ever wondered what a mechanical chicken factory looks like, you can now sneak peek into one with Eggomatic slot by NetEnt. It’s a peculiar slot theme but quite fantastic gameplay.
Bible Slots collection Nothing escapes the online slots these days, even religion. Based on the Holy Bible, this series was voted the best free slot games in 2013 and is exactly what it says, a stack of Christian stories inspired games. It might even prompt you to read the Bible.
Cash ‘n Curry – Microgaming Indian curry is some of the best around the world but seeing it splashed across the screen is outright bonkers or is it? Most likely based on the third episode of the BBC sitcom Only Fools and Horses, the Microgaming slots is as fun as it’s weird.
Monty Python’s Spamalot – Playtech Monty Python’s Spamalot is another bizarre but seriously entertaining slot game. It’s based on an equally amusing musical comedy adaptation of the 1975 cult film Monty Python and the Holy Grail. Check it out!
Hell’s Grannies – Microgaming They aren’t just layabouts in lace. They are a gang of vicious grannies who come up to you and push you, shove you off the pavement. That’s Hell’s Grannies, another slot based on the hilarious Monty Python series.
