Thunderkick reimagines Arthurian legend in this innovative “book” style slot that breaks convention with its unique Power Reset feature. While starting with fewer free spins than typical for the genre, Sword of Arthur compensates with an ingenious system that resets spin counts and increases multipliers after expanding symbol wins, creating potentially massive win sequences. With high volatility and a substantial 10,000x max win potential, this medieval adventure offers both visual splendor and exciting gameplay mechanics for fans of high-risk, high-reward slots.
Thunderkick's Sword of Arthur brings fresh innovation to the popular “book” style slot genre with its unique take on the legendary tale. This Swedish developer has crafted a visually striking medieval adventure that maintains their reputation for creating aesthetically pleasing games, reminiscent of their Midas Golden Touch 2 but with its own distinct character.
Legendary Symbols and Royal Payouts
The 5×3 grid showcases a rich array of Arthurian symbols that transport players to Camelot's glory days. The paytable features classic card ranks (10, J, Q, K, A) as lower-value symbols, while the medium-tier pays include meticulously designed shields, armor, and a majestic golden helmet. King Arthur himself represents the premium symbol, offering the highest regular payouts. Most crucial to gameplay is the sword symbol, which serves dual purposes as both a wild substitute and the scatter trigger for the bonus round.
From the screenshots, we can see the game's golden-framed reels set against a picturesque medieval landscape with castle columns and stone architecture. The sword in the stone is prominently featured in the background, staying true to the legendary tale that inspired this title.
Sword of Arthur's Revolutionary Bonus Mechanics
What truly distinguishes Sword of Arthur from other “book” style slots is its innovative bonus game mechanics. Landing three or more sword symbols triggers the feature, initially awarding only 3-5 free spins—fewer than typical for this genre. However, Thunderkick introduces a game-changing “Power Reset” mechanism that keeps the excitement building throughout the bonus round.
The bonus begins by selecting a random regular symbol to serve as the special expanding symbol. Starting with an x1 multiplier, this symbol expands across entire reels whenever it creates winning combinations, without requiring adjacent positions. After each expanding win, two important events occur: the spin counter resets to its initial value, and the multiplier increases by one level. This creates tremendous potential for extended bonus sessions with progressively larger wins.
For players seeking immediate action, Thunderkick offers three Bonus Buy options:
Standard bonus trigger for 125x bet (RTP 94.45%)
Guaranteed 5 free spins for 200x bet (RTP 94.47%)
Guaranteed Arthur symbol selection for 500x bet (RTP 94.5%)
Additionally, the base game features two “Bet+” options that increase bonus trigger probability by either 2x or 5x, with slight RTP improvements to 94.4% and 94.43% respectively.
The Arthurian World: Visual Splendor and Medieval Majesty
The visual presentation of Sword of Arthur showcases Thunderkick's artistic excellence through a richly detailed medieval setting. The game unfolds against a backdrop of majestic castle architecture with golden pillars framing the play area, while the legendary sword in the stone sits prominently to the left side of the screen.
During daylight spins, players enjoy clear blue skies and lush greenery surrounding the play area. As the bonus round activates, the atmosphere shifts dramatically to a sunset palette of rich golds, purples, and reds, creating a visual transformation that enhances the gameplay experience.
The symbols themselves reflect meticulous design work, particularly the premium icons. King Arthur appears noble and determined with his golden crown and royal attire. The knight's equipment – from the golden helmet with its ornate crown to the gleaming silver armor and decorated shield – all convey the high medieval craftsmanship of Camelot. The magical sword itself glows with blue mystical energy, instantly recognizable as an object of power and destiny.
This atmospheric presentation creates an immersive gaming environment that supports the legendary theme while maintaining visual clarity for gameplay. The color transitions between base game and bonus features serve both aesthetic and functional purposes, providing clear visual feedback about the game state.
