Christmas Slots

We all love Christmas right? There’s been a rise in Christmas slot games as we celebrate the festive season with loved ones. Many of us will consume an enormous amount of food and plunk ourselves in front of the telly. We will also play slot games on our smartphones. Slot providers offer festive versions of their most popular games with some even creating unique games to enjoy if you want to escape the in-laws or watching Home Alone for the umpteenth time.

Egyptian Slots

Ancient Egyptian slots are synonymous with the online and land-based casino world. The lure of finding lost treasures in ancient burial sites that were left by the Pharaohs has made this particular theme arguably the most popular among slot providers. Slots like Book of Ra Deluxe (Novomatic), Book of Dead (Play ‘n GO) and Cleopatra (IGT) are amongst the most played slot games ever with many clones and imitations.

Fishing Slots

With fishing being such a popular hobby, there’s been a huge rise in fishing slots. Maybe it’s the thrill of reeling in a big catch or the enjoyment of isolation. The rise in popularity is due to some arcade/land-based favourites like Fishin’ Frenzy and then the Big Bass series from Pragmatic Play. All other slot providers have created slots with a fishing theme too which has resulted in some of the most played online slots in recent years.

Fishing-Themed Slots

Wild West Slots

Depicted in countless movies, Wild West-themed slots are extremely popular with all slot providers. There’s something about rocking up (on a horse of course) to a dusty town and joining the bandits or acting as the sheriff. Players can saddle up and shoot their way to wins. The likes of NetEnt and Nolimit City have created some superb slot games with most of them offering great visuals and compelling soundtracks.

Western Slots

Irish Slots

Do you want the luck of the Irish? With Barcrest’s Rainbow Riches kicking off the trend, Irish themed slots are associated with luck, pots of gold at the end of the rainbow, green meadows and, of course, riches. Many of them feature leprechauns, harps and 4-leaf clovers with many slot providers now creating modern twists on the traditional theme.

Irish Luck Slots

Norse Mythology Slots

Norse mythology-themed slots are also very popular amongst players. Featuring ancient Greek gods such as Zeus, Odin and Thor, there are many movies or TV series including Vikings and the Thor films by Marvel. Slots benefit from epic battle scenes, iconic folklore storylines and grand-looking characters fighting for supremacy. Norse mythology slots are action-packed, graphically superb and offer the potential for big wins.

Space Slots

Many of us are intrigued by outer space and searching for extra-terrestrial life. As a result, there are many spaced themed slot games which see players shooting for the stars in search of cosmic-sized wins. NetEnt’s Starburst paved the way with slot providers able to create games based on new worlds and aliens with no limit to the possibilities, graphically at least.

Animal Slots

As a nation of animal lovers, there is an abundance of animal-themed slots available. Ranging from cute kittens to sharks, there are many animal slots to choose from. Slot providers can create games based on various animals which have human characteristics or take you to the grasslands of the African savannah. As a result, you have buffalos stampeding their way through the African plains or rabbits eating carrots to give you 5×5 wilds. The possibilities are endless.

Branded Slots

Branded slot games are becoming increasingly popular with slot providers creating slots based on television shows/series, blockbuster films, music bands and artists. The rise in streaming platforms like Netflix and Amazon Prime have made us binge our favourite programmes obsessively and officially-licensed slots are being created as a result. This has resulted in the ability to watch the likes of Vikings, Narcos and Game of Thrones whilst also playing the official slot game at the same time.

Halloween Slots

Love a good horror movie? You’re in luck as there are plenty of Halloween slots to enjoy. These include games with horror, witch, zombie, mummy, ghost, vampire, serial killer, werewolf and Day of the Dead themes. Like with Wild West or Egyptian slots, there are plenty to choose from with all slot providers jumping in on the action. Halloween-themed slots have some of the best graphics and soundtracks we’ve come across

What are themed slots?

All online slot games have a theme as such but some play into the characters, setting or topic more than others. Whilst many factors make a slot game stand out compared to others, the way slots are presented has an obvious effect.

A cool design or superb graphics and animations might be enough to make an online slot stand out against the crowd. You may have a brilliant game with good win potential and engaging bonus features but if the theme is outdated or simple, it may be overlooked by many players.

On the other hand, slots that are aesthetically appealing may be quite simple in terms of gameplay or mechanics but are popular due to being easy on the eye. The good thing is that there are so many themed slots to choose from so you are spoilt for choice. Some are more popular than others obviously and this is for good reason.

With thousands of online slots to play, slot providers need to stand out from the crowd. With certain themes, they are able to show off their creative and artistic flair. With high-definition graphics and animations, themed slots are so good visually that they could feature in blockbuster movies or television series.

The storylines are compelling and the concepts can be ground-breaking. Whereas slot providers created games using lucky 7s, golden bells and cherries, the possibilities are endless allowing for video game-quality slots that players engage with time and time again.

If you take Immortal Romance by Microgaming/Games Global which was released in 2011, the game has a vampire theme and tells a “tale of love and intrigue”. It was the first game to develop a custom soundtrack which has a song for each of the game’s characters. The graphics and storytelling make it stand out and is still one of the most popular slot games around (more than 12 years on).

Why do we play slots with a certain theme?

Players love themed slots because it resonates with their personal preferences. For example, there’s been an influx of branded slots because people are fans of a certain television series, film or music band/artist. Some like to revel in the mystery of ancient Egyptian times or explore the unknown in outer space.

Fans of horror movies will love Halloween-themed slots or those of us who love everything festive, there’s an abundance of Christmas slots with many new games released every single year. Fishing is a very popular hobby and hasn’t resulted in an explosion of fishing-themed slots. Pragmatic Play and Blueprint Gaming in particular have many of them with their respective Big Bass and Fishin’ Frenzy slot series.

In short, players are more like to play online slots that resonate on a personal level. Certain slot themes create a sense of nostalgia, romance, escapism and excitement. Slot providers have capitalised on this and created engaging and immersive games that play to those personal preferences.

Unusual slot themes

More and more slot providers are moving away from traditional slot themes like fishing or the Wild West to create unusual games. As mentioned above, they want to show off their creative talents and produce unique-looking slots that catch the eye. Here are 3 slot providers who are pushing the boundaries in terms of themes:

Nolimit City: Known for controversial slots, they have games based on prison (San Quentin), serial killers (Kiss My Chainsaw), mental asylums (Mental), the US/Mexico border (The Border) and the Soviet Army (Remember Gulag). Graphically, there are second to none with custom soundtracks for each slot. Featuring innovative mechanics, they are known as the South Park of slot providers.

Print Studios: A relative newcomer on the block, they claimed the Best Slot Provider title at our 2023 awards. You have slots based on The Occult (Darkness), potatoes (Royal Potato and Royal Potato 2), religion (Holy Hand Grenade) and winter (Pine of Plinko 2) which are simply exceptional. Print Studios does things differently with mechanics and bonus features to match the excellent concepts, graphics, animations and soundtracks.

Relax Gaming: Whilst Relax offers many slots with popular themes, they’ve been particularly successful with steampunk (Money Train 4), biker (Dead Rider’s Trail), animal/weight-lifting (Beast Mode) and adventure (Cluster Tumble) themes. They also offer Dream Drop/jackpot versions of their most popular titles.
