Slot themes are essentially the genre of a slot. If you think about music, it can be produced in various styles such as rock, pop, classical or reggae. Slots have just as much variety and can be developed with themes such as animals, fruits, wild west, magic, adventure, underwater, and so on.

Developers then build on these themes to create unique characters, befitting symbols and innovative bonus features. Just like how pop records are produced by various artists and sound totally different but still fit into the category of ‘Pop’, so too can many slots have the same genre or theme, e.g. magic, but have very different features and gameplay.

Developers ensure that their game portfolios contain a good mix of themes to cater to different slot players. Our slot guide will take a look at some of the more popular choices, which include adventure, music, space, fruits, animals and horror, amongst others.

Top 20 Slot Themes

Slots are undoubtedly the most popular online casino games to play, and as is to be expected, many developers want to share in the love! Try thinking of a theme and we can pretty much guarantee that it’s been done. With that said, let’s take a look at the top 20 themes and some of the most popular slots which fit into that genre.

Asian-Themed Slots

Asian-themed slots attract many players from far and wide. This may be due to the elaborate visuals, which are typically very bold, often using the colours red and gold, or the myths that surround particular far eastern cultures. You can be certain developers will tap into every avenue.

For example, old Chinese coins which are round with a square hole in the middle, said to represent heaven and earth, or the use of Fu, a Chinese character representing good fortune and good luck, or the number 8, which is broadly associated with wealth, success and status.

Popular Asian-themed titles include Light & Wonder’s 88 Fortunes, Red Tiger’s Dragon’s Fire Megaways, NetEnt’s Imperial Riches.
