Book of King Arthur Online Slot by Microgaming and Just For The Win offers a scaled-down Arthurian experience with punchy, impactful features. The slot’s styling matches the relative simplicity of the game with the reels encased in metal armour against the backdrop of a castle interior. The game’s symbols are represented by the king himself alongside his regal accessories. The bonus features include free spins and expanding wilds.

Game Symbols

  • J to A card royals are the low-paying symbols.
  • A shield, a grail, Excalibur, and King Arthur himself are the high-paying symbols.
  • The Book symbol acts as both a wild and a scatter, it stands in for any other symbol and activates free spins.

Bonus Features

Free Spins

If 3 or more book symbols appear on the reels, you will be awarded 10 free spins and a wheel will spin to choose a special expanding symbol for the round. Whenever the expanding symbol land, it will grow to cover the entire reel. The feature can be retriggered by landing 3 more scatters while it is active and if you would rather not spin to get to the bonus, you can use the Buy feature to trade 80x your stake for 10 free spins.


This is an opt-in feature that changes all wilds that land into expanding wilds that fill the entire reel in exchange for you doubling your bet.

Our Verdict

Book of King Arthur slot wields simplicity like a broadsword while offering attractive potential. The slot’s theme is minimal to match the relatively simple gameplay. The chunky armour frame around the slots and the out of focus background alone are executed well enough to immerse you in the legend of Arthur. The boost and buy features are very handy, both offering you the opportunity to greatly boost your winnings for a calculated gamble. The free spins mode is the most important feature as it gives you the chance to win the slot’s top potential of $250 000. This title shows exciting levels of innovation in its translation of the ‘book of’ slot genre and uses its features well to create engaging gameplay.
