9 Most Popular Online Slots Themes

Dozens of online slots themes exist throughout the gaming world. Developers make games about everything from history to sports. Of course, some themes are more prevalent than others at mobile casinos.

Developers have found that these subjects resonate more with online gamblers than any other. That said, I’m going to discuss nine slots themes that are extremely popular at internet casinos.

1 – Ancient Egypt

No theme is more popular at mobile gaming sites than Ancient Egypt. Countless games revolve around Cleopatra, Anubis, Horus, and the Great Pyramids.

Cleopatra is an especially popular subject. She has starred in many classic online slots, including Cleopatra‘s Gold, Cleopatra: Queen of the Nile, and Cleopatra.

When slots makers aren’t focusing on the Queen of the Nile, they like to make games about Egyptian gods. Anubis is definitely one of the most popular gods in this genre.

The god of death and afterlife often appears as a wild or scatter symbol in ancient Egypt slots. Other common symbols in these games include scarabs, sphinxes, pyramids, and royals (A-9) styled as hieroglyphics.

Thanks to the popularity of Egyptian slots, you needn’t look far for big win potential. Mega Moolah Isis takes the cake with its progressive jackpot, which is currently worth $9.6 million at the time of this writing.

2 – Asian Culture

Asian-themed slots run a close second to ancient Egypt regarding popularity. In fact, they seem to be growing at an even faster pace than Egyptian-inspired games.

Many of these slots revolve around Asian good luck symbols, including gold coins, dragons, firecrackers, and red envelopes.

RealTime Gaming (RTG) makes many of these types of slots. Plenty of other developers dive into the Asian genre quite frequently too.

Of course, not all Asian-themed online slots center on good luck symbols. Some of them also have more original themes that deal with history, myths, and war.

Zanshi is a popular slot that falls into the latter category. It revolves around a skilled general who’s defending his fort on the steppes.

Wu Zetian is another popular game from this category. It focuses on China’s first female emperor and boasts high-quality graphics.

3 – African Safari

African safaris have been popular sources of entertainment for centuries. Apparently, safaris are just as popular in the gaming world, too.

Developers love taking players to the African jungles and savanna. They feature exotic animals in these games, including lions, giraffes, gorillas, zebras, and elephants.

You can play for huge jackpots through some these slots. Microgaming’s Mega Moolah, for instance, is connected to the same network as Mega Moolah Isis ($9.6m jackpot right now).

You’ll also find African safari slots with innovative features, too. For example, Safari Gold Megaways offers cascading reels, mystery symbols, and free spins.

4 – Treasure Hunting

As a slots player, you might feel like a treasure hunter who’s in search of big payouts. If so, you can live out your treasure-hunting fantasies through a wide range of games.

Software providers have collectively produced numerous games for this genre. They send players everywhere from long-lost Mayan temples to Egyptian pyramids in search of lost artifacts.

Novomatic’s Book of Ra is one of the most legendary treasure hunting games. It shows an Indiana Jones-style adventurer who raids burial tombs in search of the infamous Book of Dead.

WGS’ Amanda Panda and the Jackpot Journey is another example. This five-reel, 25-payline slot offers free spins, scatter payouts, and a second-screen bonus.

Assuming you appreciate movies like The Mummy and National Treasure, then you’re bound to enjoy these types of slots.

5 – Wealth

Slot machines and wealth have gone hand in hand for decades. Developers commonly produce games that feature yachts, diamond rings, Lamborghinis, and champagne.

If you have a taste for the finer things in life, then you may like these kinds of games. You’ll especially appreciate them if you can get rich yourself.

NetEnt’s Mega Fortune is notable for its huge progressive jackpot. It currently offers a jackpot worth almost $2 million.

Even if you don’t have delusions de grandeur about striking it rich through slots, you can still find plenty of fine games within this genre.

Shanghai Nights offers a cool combination theme that focuses on both wealth and Shanghai’s luxurious side. Produced by RealTime Gaming, this slot follows the adventures of a Chinese playboy and his opulent lifestyle.

6 – Greek Gods

Greek mythology is a favorite subject of school students. It also translates over to the mobile gaming world in a big way.

Developers produce slots on a variety of Greek gods and goddesses, including Zeus, Hera, Aries, and Hades.

Of course, Zeus is no doubt the biggest star in this genre. He has headlined many online slots, including Zeus Lightning: Power Reels, Mighty Zeus, and the Zeus trilogy (WMS).

You’ll also find plenty of games based on the god of thunder’s son, Hercules. Some of these slots include Hercules: High and Mighty, Hercules: Son of Zeus, and Hercules and Pegasus.

7 – Gems

Gems are among the most classic slots symbols. Slot machines have been featuring diamonds, emeralds, rubies, and sapphires since the early days of casinos.

Of course, gem-themed games aren’t the most exciting today. But they still find their way into many mobile slots.

Software developers normally put a twist on these games to make sure that they’re not too classic. Play’n GO’s Gems Bonanza, for example, features an Aztec slant.

If you do want a classic gem-themed slot, though, you can find plenty of them throughout gaming. Barcrest lays claim to a series of these slots, including Crown Gems and Crown Gems High Roller.

IGT’s Da Vinci Diamonds blends precious stones and Leonardo da Vinci paintings into one game. This combination is nice if you want more beyond just gems.

8 – Leprechauns

Most online casinos include multiple leprechaun-themed slots. These mythical Irish creatures show up in numerous slot machines throughout gaming.

Most leprechaun slots feature symbols like pots of gold, rainbows, four-leaf clovers, and beer mugs. They mostly cover the stereotypical Irish good luck symbols.

But like with any other genre, you can find some unique slots in this category. Rainbow Wilds Megaways is one example of a unique leprechaun slot.

It differs from the pack by offering up to 117,649 ways along with unique features, like sticky wilds and win multipliers. You can also win big payouts worth up to 12,000x your stake.

If you’re looking for a tried-and-true basic game, then Lucky Leprechaun is a good choice. This five-reel, 30-payline slot offers high-quality graphics and multiple features.

9 – Outer Space

Space exploration is a fascinating subject to many. It’s equally as fascinating in gaming because many slots games on mobile apps are based on outer space adventures.

The cool thing about space-themed slots is that they differ plenty from each other. Relax Gaming’s Multiplier Odyssey, for example, focuses on the adventures of futuristic humans. Meanwhile, SG’s Invaders from the Planet Moolah revolves around a simple space invasion.

Of course, clichés also exist in the outer space genre. This is especially true when it comes to gems floating in outer space.

Starburst started this trend in 2012, when it introduced the concept of diamonds, rubies, and sapphires floating in the cosmos. Since then, many copycats have come out.

By and large, though, space games boast lots of variation in the themes. If you’re tired of playing slots based on Zeus or Indiana Jones-like adventurers, then you should take a trip to outer space.

Conclusion

Mobile casinos offer dozens and dozens of different themes. This variety is nice for when you want to go off the beaten path and try something totally new.

For the most part, though, you’ll find that many popular slots fall into one of the nine genres covered above.

Ancient Egypt, Asian culture, and African safaris lay claim to the largest percentage of online slots. Treasure hunting, Greek gods, and wealth also comprise a dominate percentage of slots themes. Gems, leprechauns, and space round out the most-popular game subjects.

Assuming you like slots that fall into any of these categories, then you’ll never be at a loss for options. Gaming sites love rolling out slots that are based on these nine themes.
