The Green Knight: Oath of Thorns by Play’n GO plunges players into a cursed forest where Arthurian legends take a darker turn. This 5-reel, 20-payline slot features escalating Multiplier Wilds (up to x100) and a Sword Meter that intensifies during Free Spins. The new Thorn Spins mechanic locks in multipliers for five high-stakes spins, adding tension and reward. With high volatility, a 96.27% RTP, and richly illustrated medieval visuals, this slot blends lore and gameplay seamlessly.

There’s also a dedicated free spins bonus round, which is typically where the game’s biggest win potential comes into play.
The standard RTP (Return to Player) for The Green Knight Oath of Thorns slot is 96.27% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.27. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 14000x your total bet which is very high and gives you the chance to win really big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
The Green Knight Oath of Thorns is a volatile slot, and PlayN Go rates the volatility High (4/5). Volatility, in the context of slot games, refers to how often and how much a slot game pays out. The Green Knight Oath of Thorns is designed to appeal to players who enjoy the adrenaline rush of substantial winnings that low volatility slots can't deliver, making it a great fit for fans of high volatility slots who are willing to accept the inherent risks of less frequent payouts.
The Green Knight: Oath of Thorns is a masterclass in atmospheric slot design. It builds on Play’n GO’s Arthurian legacy with fresh mechanics and a darker tone. The Thorn Spins add strategic depth, while the x100 wilds deliver thrilling win potential. It’s not revolutionary, but it’s a polished, thematic experience that rewards loyal fans and feature hunters alike.
