The Green Knight Oath of Thorns

About The Green Knight Oath of Thorns

The Green Knight Oath of Thorns is a fantasy-themed slot from Play'n GO, released in July 2025 as the third instalment in the Green Knight series. It follows the original Green Knight (2021) and Return of the Green Knight (2023), continuing the Arthurian saga of the iron-clad woodland warrior who abandoned the comfort of castles for life in the forest. The reels are framed against an enchanted woodland with Camelot perched on a hill across the lake in the distance. It runs on a 5-reel, 3-row grid with 20 fixed paylines.

The game has an RTP of 94% in the version available at Midnite, high volatility, and a maximum win of 14,000x your bet. The bonus structure builds on the formula established across the trilogy: a Sword Meter that awards multipliers from 2x up to 100x applied to wilds landing on the spin, a Free Spins round where the multiplier escalates across spins towards a dramatic 100x finale, and a new Thorn Spins feature that replaces the Shield Spins from Return of the Green Knight, locking in the current multiplier and guaranteeing Multiplier Wilds on every spin.

How to Play The Green Knight Oath of Thorns

The grid is 5 reels by 3 rows, with 20 fixed paylines that are always active. Stakes at Midnite start from £0.10 per spin, set using the bet controls below the reels. Wins form when three or more matching symbols land on adjacent reels from left to right, starting from reel one.

Lower-paying symbols are 10 through Ace card ranks rendered as carved pieces of stone, paying 2x to 4x the bet for combinations. Higher-paying symbols are four Arthurian character symbols, paying 7.5x to 25x the bet for five in combination. The standard wild substitutes for all paying symbols and pays 100x the bet for five in combination on its own.

Above the reels sits the Sword Meter, which can activate randomly on any base game spin to award one of five multiplier values: 2x, 5x, 10x, 25x, or 100x. The selected multiplier applies to all wilds that land on that spin. Three or more scatter symbols trigger the Free Spins round, where the multiplier values escalate towards the maximum 100x.

The Green Knight Oath of Thorns Features

The bonus structure runs across three layered features, each building on the multiplier system that runs through the entire trilogy.

• Wild Symbol: The standard wild substitutes for all standard paying symbols on a payline. Five wilds on a payline pay 100x the bet on their own.
• Sword Meter: The Sword Meter above the reels can activate randomly on any base game spin. When triggered, a multiplier value of 2x, 5x, 10x, 25x, or 100x is selected. The multiplier applies to all wilds that land on that spin, with the wild win value multiplied by the chosen amount.
• Multiplier Wilds: Wilds carrying multiplier values appear during Free Spins, applying their multiplier directly to wins they contribute to.
• Scatter Symbol: The scatter pays from any position on the reels. Three, four, or five scatters trigger the Free Spins round and award a bet payout.
• Free Spins: Triggered by 3 or more scatters. During Free Spins, the Sword Meter multiplier escalates across spins, climbing through values up to 100x by the final spin of the round. The progression builds dramatic tension as the multiplier value climbs.
• Thorn Spins: Triggered when 2 scatters land during Free Spins. The Free Spins phase pauses and 5 Thorn Spins begin. The current multiplier value is locked in place for the entire round, and a Multiplier Wild is guaranteed to land on every spin.
• Bonus Buy: Available in some markets but not in the UK. UK players cannot use Bonus Buy due to UK Gambling Commission regulations and must trigger the Free Spins round through scatter symbols.

The Green Knight Oath of Thorns Theme and Symbols

The setting is a darker, more sorcerous version of the Arthurian forest established across the trilogy, with the reels framed against a moody woodland clearing where ancient trees, twisting thorned vines, and ruined stone archways crowd the playing field. Across a misty lake in the distance, Camelot's silhouette rises on a hill, lit by the slow-burning sky behind it. The new Thorn Creature lurks in the background art, a beguiling entity whose gifts both enrich and endanger the player. The soundtrack is full orchestral with horn flourishes during wins and a darker, more ominous arrangement during the Free Spins phase as the multiplier climbs.

Lower-paying symbols are 10, J, Q, K, and A card ranks rendered as carved pieces of stone. Higher-paying symbols are four Arthurian character symbols pulled from the saga, paying 7.5x to 25x the bet for five in combination. The standard wild and Multiplier Wilds make up the special set, alongside the scatter symbol that triggers the Free Spins round.
