Thunderkick’s Sword of Khans Slot Review

The Sword of Khans slot is from Thunderkick and comes with 5 reels and 50 paylines – based on Genghis Khan, you can spin away from 10p to £100 per spin on all devices. With an RTP of 95.36%, it comes with free spins when a random symbol is chosen to become the expanding symbol for hopefully a screen full of that symbol. If that expanding symbol is active, a multiplier up to 3x is applied for wins of up to 10,000 times your stake.

Sword of Khans Theme/Symbols

To look at, the Sword of Khans slot looks superb – it’s based on the legendary Genghis Khan so focuses on the Mongol Empire (who were the largest empire in history). Visually, you’ll see a mountain range in the backdrop with the reels encased in a traditional Mongol temple. Symbols include A, K, Q, J and 10 royals. You’ll also see armour, helmets, shields and Genghis Khan – here’s what each of the symbols will give you:

  • Q, J & 10 symbols – 3, 4 or 5 will give you 0.5, 2 or 10 x stake
  • K symbols – 3, 4 or 5 will give you 0.5, 2.5 or 12.5 x stake
  • A symbol - 3, 4 or 5 will give you 0.5, 3 or 15 x stake
  • Shield symbol – 2, 3, 4 or 5 will give you 0.5, 2, 10 or 30 x stake
  • Armour symbol - 2, 3, 4 or 5 will give you 0.5, 2, 12.5 or 40 x stake
  • Helmet symbol - 2, 3, 4 or 5 will give you 0.5, 4, 15 or 50 x stake
  • Genghis Khan symbol - 2, 3, 4 or 5 will give you 0.5, 10, 50 or 250 x stake

Sword wild/scatter symbol

The sword symbol is both the wild symbol and the scatter – as well as substituting for all other symbols, 3, 4 or 5 swords will reward you with 2, 20 or 200 times your stake.

3 or more sword symbols will trigger the Bonus Game feature. You will then be rewarding with a random number of free spins – either 5, 7, 8, 9, 10, 12 or 15 free spins. During the feature, just 2 or more sword symbol will retrigger additional free spins.

Expanding Win feature

Any symbol, bar the sword, is chosen randomly to become the expanding symbol for the duration of the free spins. When it appears, it will expand to take over the whole reel it appears on. This is known as the Expanding Win feature and works like in Play ‘N Go’s Book of Dead slot.

However, the difference is that you can benefit from the Increasing Multipliers feature – if the selected symbol is an active expanding symbol, a multiplier is then applied. An expanding symbol can have a multiplier up to 3x.

Sword of Khans thoughts

Visually, Sword of Khans looks great – as do all Thunderkick slots really. It’s all about the Bonus Game feature really as getting a high value expanding symbol can lead to big wins on each free spin – the key is to get the Genghis Khan symbol as a screen full of symbols will result in a 2,500 times stake payout. Add in the multipliers and the potential rises to 10,000 times your stake.

In terms of the mechanic, it’s similar to Novomatic’s Book of Ra Deluxe or Play ‘N Go’s Book of Dead (expanding symbols) but Sword of Khans takes it further by adding in the multipliers. Overall, another superb game from Thunderkick. The only downside is that the RTP is 95.36%.
