The Green Knight Oath of Thorns is a video slot developed by Play’n GO, released on the 24th June, 2025. It marks the return of the Arthurian saga, following its predecessors, The Green Knight and Return of the Green Knight slot. With its richly illustrated medieval setting, it builds on the tale with richly illustrated graphics, a new chapter where valour and fate collide across the reels.

This slot delivers a familiar structure featuring wild multipliers, shield symbols, and a bonus game that echoes the format of its predecessors. While it doesn’t stray far from the tried and tested formula, fans of the series will find a solid addition here.

Technicals

The Green Knight: Oath of Thorns has a 5×3 layout with 20 fixed paylines. It’s highly volatile with a return to player (RTP) of 96.27% and a maximum win capped at 14,000x the bet. Stakes range from 10p to £100 per spin. Core mechanics include Wild Multipliers, Thorn Spins, and a progressive Free Spins feature with locked multipliers. The new Sword Meter randomly triggers multipliers during the base game.

Design and Symbols

The reels are set in the centre of a dense, dark forest, where tangled trees and vines frame the grid, shrouded in a green fog. Once an adversary, the Green Knight has chosen a new path by standing alongside warriors – a shift echoed in the darker, more intense visual tone.

The soundtrack ties everything together. Eerie orchestral layers mix with clashing swords, shifting vines, and distant bells, with additional effects when a win hits or a feature triggers. It is an excellent example of Play’n GO’s talent in storytelling.

The low-paying symbols are carved stone card suits, awarding 2x to 4x for five of a kind. Premium symbols feature Sir Gawain, Merlin, Morgan le Fay, and Sir Lancelot, awarding between 7.5x and 25x the bet for five matching symbols. The Wild is the Green Knight’s totem and awards up to 100x for five, or 10,000x when combined with the 100x multiplier. The Scatter is the Green Knight and unlocks the free spins bonus.

Features Overview

Thorn Spins takes centre stage during the free spins, ramping up the volatility and setting the tone for the highest potential. Alongside that, there is the Sword Meter that randomly triggers multipliers during the base game. And a series of Wild Multipliers, each with the potential to increase base game wins. Each feature builds upon mechanics from the original, with a few extras added.

Sword Meter

Above the reels is the Sword Meter – a rotating display with five multiplier values: x2, x5, x10, x25, and x100. During the base game and free spins, the sword ignites randomly and selects a multiplier. Any wild landing during the following spin receives the chosen multiplier if it is involved in a win.

Free Spins

Landing 3, 4 or 5 Scatters triggers five free spins, and a payout of 2.5x, 5x or 100x, respectively. During the free spins, the sword Meter increases by 2x on the first spin to 100x on the 5th spin.

Thorn Spins

If two more scatters land during the free spins, five extra free spins are awarded. The Sword Meter values lock on their value from the spin immediately before it triggered. Additionally, on each of the Thorn Spins, Wilds are placed in random positions on the grid.

Conclusion

The Green Knight: Oath of Thorns doesn’t break with the familiar format, but it doesn’t need to. It delivers stunning graphics, familiar mechanics, and a layered bonus structure for those seeking a highly volatile challenge. The Wild multipliers and Sword meter add additional extras, but it does feel like it’s lacking spark. If you enjoyed the first two in the series, you’ll probably love this one, more for the stunning artwork and animations rather than the gameplay mechanics and win potential.
