Slot themes remain relevant – here’s why
Every time I walk into a casino floor, or look at an online casino lobby, I see the same things. The majority of the slot machine games are played regularly, and many of those are the old favorites. Cherries and bells, gold and hieroglyphics, or shamrocks. So many new slot machine games are released every year (hundreds), and yet some common slot machine themes are constantly reused. This isn’t laziness on the part of the Developers.
Why do evergreen slot machine themes continue?
So, why do cherry and Egyptian god slots continue to endure? The key is cognitive load. A player decides quickly if they’re going to keep browsing or place a bet. A theme that needs zero explanation, such as cherries equate to cherries, a scarab equates to good fortune, a pyramid represents treasure, decreases the cognitive load on that decision. In contrast to an entirely original fantasy world with its own lore, characters and visual identity you’ve never seen before. While an original fantasy world may be beautiful, it is asking something of the player before it provides them with anything in return. Nostalgia works psychologically here as well. A collection of spinning fruit reels, or a catchy little melody reminiscent of a seaside arcade, taps into autobiographical memory — the memories associated with specific locations and times in a person’s life. The type of Nostalgia-driven design will generally decrease stress levels and improve moods, which increases the likelihood a player will try the game and also continue playing once they have started.
Cross-generational appeal
Another aspect of this group is the cross generational appeal. A theme based upon ancient Egypt or Greek mythology will age differently than a theme centered around memes or songs.
Ancestor of everything
Fruit machines are the ancestor of nearly everything in this industry. The symbols used in fruit machines include: cherries, lemons, oranges, plums, watermelon, grapes, bar signs in single, double and triple configurations, lucky sevens, bells, stars and horseshoes. These symbols are so deeply ingrained in gambling culture that even people who have never physically pulled a lever recognize them immediately. One of the reasons for this widespread recognition is land-based heritage.
Pub slots in the u.k., arcade cabinets, mechanical three-reel machines found in casinos from Reno to Blackpool, all created a shared visual vocabulary long before anyone had even heard of “online casino.” today a developer creates a new fruit-themed slot machine game they are not creating something new they are building upon the existing visual vocabulary developed over more than 80 years of “muscle memory.”
Casual players and low-stakes players
One reason fruit slot machines continue to perform well in casual and low-stakes segments is that there is minimal learning required to play them. Since there is no storyline to follow and no character development during the bonus round, players can simply view the clean and honest reels. The simplicity of the gameplay is one major factor as to why fruit slot machines continue to thrive among casual and low-stakes players.
Modern studios have not abandoned this category
Modern studios have not abandoned the category of fruit slot machines. Many examples exist of classic fruit slot machines recreated with advanced mechanisms such as cascading reels or rebuilt with Megaways engines. Examples also exist of fruit symbols created in 3-d with animations that appear when the symbols land on the reels.
Egyptian and other mythological themes
If fruit slot machines represent the root of the industry then ancient Egypt is its most consistent source of inspiration. The question remains however as to why Developers continue to produce Egyptian-themed slot machines. The answer lies within the fact that ancient Egypt-themed slot machines provide a tremendous amount of narrative value without requiring a single line of written dialogue. The images used in Egyptian-themed slot machines tell a story. A pyramid represents treasure, a sarcophagus represents mystery, and a scarab beetle represents luck. Therefore none of those concepts require any additional context. Similarly to ancient Egypt, Greek and Norse mythology serve the same purpose, although using a different cast of characters. Zeus, Hades, poseidon and Athena represent one pantheon while Thor, Odin, Loki and asgard represent another. Both pantheons use easily identifiable heroes and villains as well as rich imagery to create a sense of grandeur and power suitable for large win moments and exciting bonus rounds.
Roman-themed slots using gladiators and emperors
Roman-themed slot machines fit into a similar area as Egyptian and mythological themes in terms of providing a sense of History and grandeur. Like Egyptian themed slot machines roman themed slot machines rely on players’ prior knowledge of ancient Rome acquired through school books, movies or documentaries long before they ever opened a casino application.
Cycles of ideas repeatedly used successfully
It is surprising how often identical structural concepts are repeated successfully. Examples include book-style games where a unique expanding symbol tied to the central icon or object in the theme triggers free spins. These types of games were successful with Egyptian gods, Greek gods and Norse gods.
Animal-themed slot machines
Animal-themed slot machines fit into a slightly different psychological area than mythological themes but are just as durable. Wildlife/safari slot machines utilize bold color and dramatic imagery of powerful animals to create instant excitement worldwide. Because Wildlife/safari slot machines use images universally recognized by players everywhere in the world they are able to reach international audiences effectively without needing translation beyond the pay table values.
Ocean/fishing-themed slot machines
Ocean/fishing themed slot machines deserve their own category due to their massive popularity in certain areas. Fish shooting/fishing-type slot games particularly popular across many areas of asia combine the treasure hunting instinct with an actual arcade-type feeling of pursuing something. There is something appealing about catching something whether it is an actual fish or a chest filled with coins. That appeal transcends cultural backgrounds.
Themes based upon luck/good fortune
Many of the most enduring slot machine themes are not about adventure but about luck itself represented through cultural symbolism. Lucky Irish slots utilizing leprechauns, shamrocks, four-leaf clovers and pots of gold have been staples of this industry for decades now and are basically shorthand for “good luck” even outside Ireland. Generally games within this category maintain a light-hearted tone and feel good natured which fits perfectly with players seeking entertainment rather than serious dramatic/ high-stake gaming experiences.
Asian-luck theme
Similarly, Asian-luck themes, including chinese-luck symbolism hold immense importance due to sheer size of the Asian gaming community. Symbols representing dragons, koi-fish, red lanterns, gold ingot boxes and red envelopes related to Chinese New Year represent specific aspects of good fortune/prosperity. These are not arbitrary decorative elements but carry true cultural significance for millions of players worldwide thus it’s no surprise that Developers continually revisit this category instead of treating it as a one-time fad.
Wealth/luxury theme
Finally, we have the wealth/luxury category comprised of gold BARs, diamonds/jewels/vaults/stacks-of-cash etc. This theme taps into perhaps an even more universal desire than any cultural-specific theme: the dream of immediate wealth/riches.
Pop-culture/branded-slots: Hits & limits
Pop-culture/branded-slots represent a truly distinct category from those previously mentioned and deserve honesty regarding trade-offs. A slot machine designed around a hit movie, TV show/music artist/etc., can immediately generate significant buzz almost instantly because the identification is built-in prior to viewing the reels. That’s an advantage which explains why licensing agreements continue to account for a considerable portion of the industry’s release schedule. That represents a genuine distinction between evergreen themes that belong to nobody and can be revisited ad infinitum without involving a legal team. While some branded properties achieve longevity beyond initial hype (usually because the underlying property has cross-generational relevance vs being limited to one cultural moment) others will fade rapidly.
Keeping old-fashioned themes modern
Graphics are updated with improved animations/lighting/detailed symbol designs so today’s pharaoh looks completely different than yesterday’s pharaoh despite using virtually the same concept. Sound design has made great strides as well – music/musical motifs/audio atmospheres add immersion without altering what the theme represents.
Mechanically – where real innovation occurs
This is where many innovations occur mechanically – bonus features are redesigned from scratch – cascading wins/expanding wilds/multiplier ladders/gamble rounds – can be added onto old-fashioned themes that never had them before. The combination hybrid models have become an interesting trend – an Egyptian theme combined with a Megaways-style reel mechanism offers players familiar imagery along with a mechanism that feels modern/current/unpredictable.
Mobile-first has quietly altered this entire category
Older land-based cabinet layout styles designed specifically for a particular physical screen shape rarely convert directly to mobile phones (held in one hand). Thus studios rebuilding classic themes for mobile have been forced to rethink symbol sizes/animations/payout-table-readability from ground-up. The theme survives; presentation evolves quietly beneath it.
On the flipside – there exists a very valid concern (and fear) – theme-fatigue. Eventually (as happened multiple times in this category), when an entire category becomes saturated with repetition of previous concepts (e.g., Egyptian/pyramid/reel-slot-machine) players begin ignoring all subsequent versions of that theme without giving it even brief consideration.
Who plays what types of slots
While many patterns emerge throughout this industry there are several obvious ones that clearly demonstrate what types of slots attract what types of players:
Newer players who want the easiest possible experience learning curve-wise fall-back on classic fruit/bar-style games since these games typically offer simple payouts/pay tables and symbols require no explanation whatsoever.
Players interested in light-narrative hooks without investing too much mental energy exploring complex stories tend towards middle grounds offered by Egyptian/mythological themed games offering a sense of atmosphere/exploration without excessive thought/cognitive processing.
Players attracted to bright colors/big action/fast paced thrills often prefer animal/adventure-themes whose imagery conveys that pace/excitement.
Those searching for emotional connections – luck/good fortune/prosperity – tend naturally toward Irish/Asian-luck/wealth/gemstones categories.
Lastly – players interested in experiencing something currently trendy/at-least-for-a-shortwhile tend toward pop-culture/branded-titles – knowing full-well that this trend will eventually expire as well.
Cross-over occurs frequently as players explore all five categories based on their mood/preferences etc…
