The Green Knight Oath of Thorns

The Green Knight Oath of Thorns by Play’n GO is a video slot with a classic 5×3 reel setup and 20 fixed paylines. It’s based on the Arthurian legend, portraying a darker, more atmospheric take on Camelot, where a cursed forest and a new enemy, the Thorn Creature, loom large. One of the central features is the Sword Meter: when it activates, Wild symbols appearing that spin can carry multipliers of x2, x5, x10, x25 or x100, boosting any win they help create. Free Spins are triggered by landing three or more Scatter symbols in the base game, awarding five spins at first. During Free Spins the Sword Meter escalates in power with each spin, culminating in x100 multipliers on the final spin. There’s a nested bonus called Thorn Spins: if two or more Scatters land during Free Spins, Thorn Spins begin—five spins where the current multiplier is locked, and every spin includes 2–3 guaranteed Multiplier Wilds. Scatters can’t fall during Thorn Spins and the feature can’t be retriggered in that phase. The game’s visuals lean heavily into mythic medieval iconography—swords, knights, misty woods—combined with rich illustration and a brooding tone. The maximum win tops 14,000× bet, and the volatility is high, meaning big outcomes are possible though less frequent.
