Sword of Khans (Thunderkick) Slot Review

Sword of Khans – Slot Overview 

Thunderkick’s Sword of Khans is a high-volatility online slot that brings a bold twist to the popular “Book of” genre, made famous by titles like Book of Ra Deluxe and its many imitators. Instead of a mystical tome, Thunderkick hands you a sword — a fierce Mongol weapon that doubles as both wild and scatter. Set against a backdrop inspired by the sprawling Mongol Empire under Genghis Khan, the game invites players on a conquest for riches as mighty as those of the Khans themselves. 

The action unfolds on a classic 5-reel, 3-row grid with 10 fixed paylines. While that may sound simple, the excitement lies in the powerful special expanding symbol mechanic, randomly awarded free spins, and — uniquely — stackable retriggered symbols and multipliers. It’s this blend of tradition and innovation that sets Sword of Khans apart, promising thrilling win potential of up to 10,000x your stake.

Design and Graphics 

From a visual standpoint, Sword of Khans delivers a clean, majestic atmosphere with a focus on Mongolian history and mythology. The reels are framed within a golden temple or pagoda, set against a backdrop of sun-drenched mountain ranges and rich, warm skies. It evokes a feeling of distant power and ancient glory.Symbol design is sharp and thematic. The low-paying symbols consist of stylized royal values from 10 to A, rendered with enough polish to avoid appearing generic. The high-paying symbols are much more distinctive, featuring Mongol-inspired elements such as shields, armor, swords, and a commanding image of Genghis Khan himself. The animations are restrained but effective, with the sword shimmer and glow when it acts as a special expanding symbol or triggers a feature.It’s not a slot filled with wild animation, but its elegance and clarity are part of its strength, lending a grounded feel that aligns with the warrior spirit of its theme.

Gameplay Mechanics 

At its core, Sword of Khans is a relatively simple game to understand — and that’s part of its charm. Players spin the reels on a standard 5×3 layout, with wins occurring when three or more matching symbols land on any of the 10 paylines, from left to right. 

The primary draw is its free spins mechanic and special expanding symbols, which echo the Book-style format but with a few Thunderkick twists. For starters, the game does not stick to a fixed number of free spins. Instead, when you trigger the bonus round by landing 3, 4, or 5 swords, you are awarded a random number of spins — anywhere between 5 and 15. This randomness adds a fresh sense of suspense to every bonus round. 

Another key twist is that when the feature is retriggered, a new symbol is selected to become a special expanding symbol — and it stacks with the previous ones. This allows for multiple expanding symbols in play at once, increasing the potential for full-screen wins. Moreover, Sword of Khans introduces a unique element: expanding symbols can receive multipliers of up to x3, giving even more firepower to an already potent mechanic.

Sound and Music 

The sound design in Sword of Khans matches the game’s theme perfectly. The background audio is atmospheric, composed of deep drums and ambient wind sounds that reflect the Mongol steppe. It’s immersive without being overbearing, giving the game a sense of gravitas. 

During spins and wins, subtle audio cues — such as sword slashes and metallic clashes — punctuate the action. Triggering the free spins or landing expanding symbols unleashes more triumphant tones, building the tension and excitement at just the right moments. 

It’s not a musical extravaganza like Esqueleto Explosivo 2, but the soundscape here is purposeful and effective — it immerses you in a warrior’s world without distracting from the gameplay.

Bonus Features 

The bonus mechanics are where Sword of Khans truly sharpens its blade:Sword Wild/Scatter Symbol 

The sword symbol plays a dual role. 

Acts as a wild, substituting for all symbols except already-expanded ones. 

Also acts as a scatter, triggering the bonus round when 3 or more appear. 

Free Spins with Special Expanding Symbols 

Landing 3, 4, or 5 sword symbols awards 2x, 20x, or 200x your bet respectively, and activates the bonus game. 

You receive a random number of free spins (5–15). 

A random symbol is chosen to become the special expanding symbol. 

If the required number of special symbols land on a spin (e.g., 3 low-pay or 2 high-pay), they expand to fill their entire reels. 

These expansions pay regardless of their position on the reels. 

Retriggers and Multipliers 

Retriggering the free spins awards additional spins and selects a new expanding symbol. 

Thunderkick’s twist: expanding symbols can also receive a multiplier of up to x3. 

This multiplier applies only to the special expanding symbols and not to standard line wins. 

Up to five different expanding symbols can be active during extended bonus rounds. 

With the right combination of symbols and multipliers, players can reach the 10,000x maximum win. 

This system builds suspense as each retrigger increases both the number of special symbols and the chances of hitting huge wins — making the bonus rounds feel both strategic and explosive.

Betting Options and Payouts 

Sword of Khans caters to a wide betting range. Wagers start at €0.10 and go up to €100 per spin, making it appealing to both casual players and high-rollers. 

Volatility is rated a whopping 9.4/10, which means you’ll likely see long dry spells followed by the potential for massive payouts. The maximum win sits at 10,000x the stake, which is very high for a 10-payline slot and adds considerable appeal for risk-takers. 

The only drawback in this section is the RTP of 95.36%, which is a bit lower than Thunderkick’s usual standards. While this is not a dealbreaker, it does mean the slot theoretically returns slightly less to players over the long run compared to the typical 96% benchmark. 

Still, the high win ceiling and bonus potential go a long way in making up for that.

Conclusion 

Sword of Khans is Thunderkick’s confident foray into the saturated world of “Book-style” slots — and it makes a bold impression. While it draws obvious inspiration from classics like Book of Ra, it carves out its own identity through smart additions like stackable special symbols, randomized free spins, and multipliers that enhance payout potential. 

The game offers a rich, immersive setting, smooth and rewarding gameplay, and a bonus feature that can deliver epic wins for players willing to brave the volatility. It may not reinvent the genre, but it polishes it to a fine edge, and the 10,000x max win ensures that the stakes remain enticing. 

For fans of high-risk, high-reward slots, Sword of Khans is a worthy addition to any playlist. Whether you’re drawn to its theme, its lucrative free spins, or the chance to relive Genghis Khan’s conquests with reels instead of swords, this slot delivers excitement with every spin.
