Thunderkick is usually renowned for their great looking, innovative games, which is why I was a little surprised to find that their December 2019 release, Sword of Khans, is basically another ‘Book of Ra’ clone to add to the lengthy list of book clones already in circulation.

Sword of Khans has a Mongolian Empire theme, featuring Genghis Khan himself as the highest paying symbol. There are plenty of Imperial Slots on the market but very few featuring Genghis Khan and the Mongolian Empire. Considering the infamous Mongolian leader built the largest contiguous land empire in history, in the 13th century then I think we can at least agree he deserves more recognition in slot land?

This is a 5x3 slot with 20 fixed paylines and comes with a slightly lower than average RTP of 95.36%. As you’d expect from a Book clone it is a highly volatile beast of a slot with wins up to 10,000x the bet size possible. 

Sword of Khans is all about the free spins round in which expanding symbols with win multipliers have the capability of delivering truly massive wins.

Released on 11th December 2019, Sword of Khans plays from €0.10 to €100 per spin.

Design & Symbols


Although this Mongolian Empire themed slot has sharper graphics and animations than your average Book clone, it’s still fairly mediocre stuff here from Thunderkick. The setting for the action is a typical Mongolian temple, with a static mountain range in the background. The soundtrack is a relatively sombre one, probably just about right for a horde of 100,000 soldiers marching through the icy mountain in their ceaseless quest to conquer the world. The reels make up the front wall of the temple. 

Low value symbols are the Royal card values 10-A. High value symbols are a shield, suits of armour, a Mongolian helmet, and Genghis Khan. Genghis is the highest paying symbol, with 5 along a payline awarding 250x the bet size.  As per any Book clone, the wild is also the scatter, and here it is represented by a golden sword. Five scatters on a payline award 200x the bet size, making it the second-highest paying symbol.

Special Features

  • Free Spins
  • Expanding Symbols
  • Win Multipliers

Free Spins

All the special features are only available during the free spins bonus round. 3 or more scatters trigger free spins. The number of free spins between 5-15 is chosen randomly, as is the Expanding Symbol. 2 scatter symbols landing during the bonus round fully retriggers the bonus round.


Expanding Symbols

Each time the bonus round is triggered one of the 8 regular symbols is randomly selected as an Expanding Symbol. When 3 or more Expanding Symbols (2 or more for the high paying symbols) land on different reels the Expanding Symbol expands to cover the entire reel. Expanding Symbols do not have to land on adjacent reels to count as winning combinations, nor do winning combinations have to start from the leftmost reel with Expanding Symbols.

Win Multipliers

A retrigger of free spins also retriggers the Expanding Symbol which joins the other Expanding Symbol already in play. If the chosen Expanding Symbol is already in play, then a win multiplier is added to that symbol which is then applied to all wins in which it appears. Multipliers up to 3x are possible on each symbol. 

Our Thoughts on Sword of Khans

Perhaps we’re expecting a bit too much from Thunderkick based on their previous stellar output. After all, almost every other provider has at least one (if not several) slots ‘borrowing’ the Book of Ra format. At least Thunderkick has changed the format up a little bit by randomising the number of free spins. They have also taken the novel approach of not automatically doubling all wins in the free spins round, but instead making it easier to retrigger the spins and making it possible to add win multipliers of up to 3x on each symbol. From my experience, this definitely made this game a little more player friendly than other versions. Whether or not that will go down well with the hardcore high variance players I don’t know – but it’s still a highly volatile slot with huge potential so I don’t see why not?

Overall, I was a little disappointed to find out Sword of Khans is a Book clone, but more because I typically enjoy Thunderkick’s original content more than most. However, as Book clones go this is certainly one of my favourites.
