What are the Most Popular Slot Machine Themes?

Slots have reportedly been around since 1894 — which themes are the most popular?


Everyone who has visited an online casino USA site knows that online slots dominate these platforms’ game lobbies by a significant margin. Not only are reel-spinners the most played and widely available game genre in the online gambling sphere, but the variety they offer in terms of bonus features and themes is stunning. That is something that slots at land-based casinos cannot compete with, as they have limitations non-existent in the digital sphere.

Concerning the number of themes online slots implement, the figure is truly immense. Games with rotating symbols come in pretty much any presentation imaginable. And that this number is in the several hundred should come as no surprise to those aware that over twenty-five thousand reel-spinning titles live on the Web, offering mouth-watering prizes in their free spins rounds and various mini bonus games.

Really, it is a mammoth task to pin down all the themes featured in low, mid, and high variance progressive jackpot products housed on the internet. Instead, we have decided to bring you the most commonly found virtual slot machine themes online. These are sub-categories of slots that all renowned gambling platforms can’t help but feature.

Fruit-Themed Slots


These are the traditional fruit machine symbols, excluding the bar and seven tokens.

What are fruit themed slots? In the past, fruit machine was a term that referred to games that boasted traditional slot symbols. These are cherries, lemons, bananas, oranges, plums, and watermelons. That was a definition that remained valid for decades.

Nevertheless, in this modern age, it no longer gets limited to only such online casino games for real money. The definition of a fruit slot is now broader, engulfing any title where fruits play a vital role in the overall presentation. For example, Triple Juicy Drops from Betsoft is a modern twist of a retro Vegas-style fruit machine, while Miss Cherry Nuts from BGaming is something entirely different. Going by our research, over twenty-six hundred spinners are available for real money play that feature fruits in some essential fashion.

Branded Slots

Branded slots are those that utilize the likeness or mention established intellectual properties. For instance, the famous Swedish game developer NetEnt has a Guns N’ Roses slot. To create it, they had to pay for the use of imagery that portrays Axl Rose and the other band members of this Hall of Fame rock group. Slots that utilize characters from TV shows and movies also get classified as branded slot games. The same applies to products that piggyback on renowned board games, quizzes, video games, and so on. When someone pays for a license to use something in an interactive gaming product, that is instantly a branded slot. Hundreds of such games are on hand in online casino catalogs.

Historical Slots

Okay, so there is a bit of controversy regarding this pick, as some may say it is too all-embracing. That is on account of the fact that anyone with minimum browsing skills can quickly learn that around one thousand Egyptian-themed slot titles can get played for cash prizes on the Web. The slot features of these games range dramatically, but their visuals are often similar. Ancient civilization spinners are a big deal in the interactive gaming sector, and so are Roman and Wild West ones. So, grouping them all into one category is a bit unfair. In their totality, they likely outnumber fruit games and more frequently get tied in with casino bonus deals because they appeal to younger demographics.

Animal Slots

Few people outside the casino loop, online and offline, know that Buffalos are a big deal in this industry. Aristocrat’s Buffalo slot is one of the most-played games at physical venues thanks to its Xtra Reel Power mode and Buffalo Power – Hold and Win from Playson continuously wows players online. It is truly staggering that around one hundred and fifty internet reel spinners have a Buffalo as a title character. And fifteen hundred feature an animal as their mascot. Wolf Gold from Pragmatic Play is this category’s king, with Fluffy Favourites from Eye Con and Primal Spirits from QuickSpin giving it a run for its money. Lion Gems is another Hold and Win game providing up to eight free spins with 2x Lion wilds.


Book of Darkness from Betsoft is a super famous fantasy slot no one should miss.

Fantasy Slots

Who does not love the fantasy genre? Lord of the Rings, Game of Thrones, Harry Potter. These are franchises with millions of fans, proving that magic has mass appeal. Microgaming’s vampire romp, Immortal Romance, leads this pack, followed by entries like NetEnt’s Divine Fortune and Betsoft’s Book of Darkness.

Newbie slot players should have no trouble finding a game that tickles their fancy from the sea of over a thousand myth, legend, fable, fairy tale, and sword and sorcery-inspired games out there. Words of wisdom to live by is to stay away from the fairy-heavy titles, as these may be the worst slot theme in existence. Spinners from this group to definitely avoid are Fairy in Wonderland by Expanse Studios, and Enchanted Evening by High 5 Games. But, at least they are not 40 Shades of Santa or the licensed TMZ spinner.

Irish Folklore Slots

Leprechauns are the most associated thing with Irish Folklore, a section of Ireland’s culture packed with tales of spirits, weird creatures, and superstitions. Seeing as leprechauns own pots of gold, it makes sense that there are many leprechaun and Irish-themed slots. From what we can tell, around three hundred and sixty such games populate gambling sites, with notable ones being 3 Lucky Rainbows from Spinplay, RTG’s Paddy’s Lucky Forest, and Charms & Clovers from Betsoft.

The most terrific aspect of leprechaun slots, and Irish folklore ones in general, is that most of them have a jackpot or another form of a mega prize that can get won in their bonus features. Of course, that is so to keep with the pot of gold idea that is the cornerstone of almost all little green ginger tales.
