Prime King: Riches of the Ancient - Review, Demo Play, Payout, Free Spins & Bonuses

Introduction 

We are off on an adventure looking for the riches of the mysteriously described ‘ancient’ in this online slot offering from Barbara Bang. With larger than usual 6x4 reels and 30 paylines, this game fills the screen and is striking for its high-quality graphics. Hunt for the treasure of free spins that can retrigger and look out for the wild that can transform lower-paying symbols into higher-paying versions.

If our introduction has encouraged your wanderlust, read our full Prime King: Riches of the Ancient slot review to find out more and give the free slot version a try here at Slots Temple.

Theme, graphics & soundtrack 

This choice of Barbara Bang slots takes us deep into the jungle and features beautiful illustrations that show great attention to detail in an online slot. 

The lower-paying card suit symbols are reimagined as pieces of ancient temple brickwork, while the higher-paying artefact symbols look suitably weathered and timeworn. The background has subtle animations that give the illusion of a living forest, while the soundtrack is an atmospheric mixture of percussion instruments that sets the scene without being intrusive. 

Of course, this jungle world-building will not be for everyone. If you are looking for something completely different, have a look at the Sweet Bonanza slot. This game features a similarly large reel setup and a sweet box theme. 

Prime King: Riches of the Ancient RTP and variance

The RTP of this online slot is 95.97 per cent, which is very slightly lower than the 96 per cent average for contemporary slots. The variance is high, so expect long waits between wins but larger prizes if/when they land.

Prime King: Riches of the Ancient bonus features 

While not overflowing with bonuses, there are still some good features on offer:

Wilds

These substitute for all symbols except the bonus symbols to help create winning combinations on the 6x4 reels and boost the chance of landing winning combinations. These can also appear as expanding symbols and with multipliers if the free spins game is unlocked.

Free spins

The bonus symbol, a mysterious box with ominous red eyes, is the key to the free spins. Bonus symbols award the following:

• 3 bonus symbols = 10 free spins
• 4 bonus symbols = 15 free spins
• 5 bonus symbols = 20 free spins
• 6 bonus symbols = 25 free spins

These free games can also be retriggered by landing the corresponding number of bonus symbols again. During this round, wilds have the potential to expand and can also have 2x or 3x multipliers attached at random. 

Prime King feature

The wild, known as Prime King, can trigger a feature when no win occurs on a spin. This turns all lower-paying symbols into higher-paying ones, potentially offering a second chance for a win. This feature occurs at random in the base game.
