The Green Knight Oath of Thorns: Slot Overview
The Green Knight Oath of Thorns is a 5x3, 20-payline video slot from Play'n GO that returns to the studio's Arthurian Legends thread for a third Green Knight outing. What stands out here is the familiar line of wild multipliers, now paired with Thorn Spins, a free-spins-within-free-spins feature that locks the current multiplier and drops guaranteed wilds onto the grid.
Compared to the studio's previous work in this mini-series, the structure is close enough that returning players will settle in quickly. I found the positioning quite clear, this is a high-volatility slot with straightforward reel play, a 96.27% RTP at the top setting, stakes from 0.10 to 100, and a 14,000x maximum win.
The Green Knight Oath of Thorns: Slot Information
5 reels and 3 rows keep the format traditional, and wins land from left to right across 20 paylines with at least three matching symbols. The low-paying set is made up of 10 to A on coloured stone tablets, paying 2x to 4x the bet for five of a kind, while the four premium royals of the realm pay from 7.5x to 25x.
Characters on the premium side are Sir Gawain, Merlin, Morgan le Fay and Sir Lancelot. Wilds replace regular symbols and pay up to 100x for five on a line. Reviews also note that a five-wild hit paired with the x100 multiplier can reach 10,000x on its own, which tells you where much of the ceiling sits.

The Green Knight Oath of Thorns: Slot Features
Sword Meter is the core mechanic in the base game. On any spin it can assign x2, x5, x10, x25 or x100 to wilds, and if a multiplier wild helps complete a win, the line is boosted by that value. A key detail is that multiplier wild wins are not cumulative on the same payline.
Free Spins trigger from 3, 4 or 5 scatters and always award 5 spins, plus an instant payout of 2.5x, 5x or 100x respectively. During the feature, all wilds are multiplier wilds and the Sword Meter climbs one step per spin, starting at x2 and finishing at x100. The design choice to make the final spin guarantee the top multiplier gives the round a clean ramp.
Thorn Spins arrive if 2 or more scatters land during free spins. That awards 5 Thorn Spins with the current Sword Meter value locked in, and each spin guarantees 2 to 3 multiplier wilds in random positions. No extra scatters can land here, and the feature cannot retrigger, so the whole idea is about squeezing value from the multiplier you carried in.
Bonus Buy Options
The meter can apply x2, x5, x10, x25 or x100 to wilds. If a multiplier wild is part of a win, it boosts that win by the shown value.
Three or more scatters trigger 5 free spins. The multiplier wild value increases by one step each spin, from x2 to x100, and only multiplier wilds matching that spin's level can appear.
Two scatters during free spins trigger 5 Thorn Spins. These lock the current multiplier value and guarantee multiplier wilds, while no extra scatters can land and the feature cannot retrigger.
