Mighty Arthur is a 5×3 video slot from Quickspin, released in November 2017 and inspired by Arthurian legend. The game features King Arthur, Merlin, Guinevere, and a medieval fantasy setting with Camelot-inspired visuals. Its defining mechanics are the Arthur Expanding Wild and Merlin Random Wilds, which can create strong winning combinations. With a maximum win of 621× the stake and medium-to-high volatility, the game is suited to players who enjoy feature-driven gameplay and atmospheric themes.
Mighty Arthur uses 5 reels, 3 rows, and 20 fixed paylines. Wins are formed through matching symbols on active paylines, with wilds substituting for all regular symbols except the Bonus/scatter symbol.
Arthur can appear as a 3×1 stacked wild on reel 3. When the full Arthur stack lands, it expands onto reels 2 and 4, making the three central reels wild and guaranteeing wins. Merlin can also appear as a 3×1 stacked wild on any reel. When a full Merlin stack lands, Merlin generates 2–6 additional wilds in random valid positions.
Partial Arthur and Merlin stacks can trigger the Mystery Nudge in the base game, giving them a chance to become full stacks. During Free Spins, these partial stacks always nudge into full stacks, making the wild mechanics considerably more powerful.
The game uses a classic medieval fantasy presentation inspired by Arthurian legend and Camelot. Character symbols include King Arthur, Merlin, and Guinevere, while other symbols feature medieval and legendary objects such as helmets, spell books, goblets, and grails. Golden-framed reels sit against a forest and Camelot-style backdrop, supported by atmospheric music, polished sound effects, and smooth animations.
The Free Spins feature is triggered when three Bonus/scatter symbols land on reels 1, 3, and 5, awarding 10 free spins.
No Bonus Buy options are provided.
