Page updated July 2026
This version of Mortal Oath is the release distributed through Hacksaw Gaming, built on the same dark Sengoku-era foundation as the original Foxhound Games title but configured with its own settings — most notably a medium-volatility profile rather than the higher-volatility build found elsewhere, plus a distinct 5x3 reel layout with 9 fixed paylines.
Mortal Oath is set during a supernatural take on Japan's Sengoku era, a period of civil war and social upheaval reimagined here as a battlefield haunted by demons and divine forces. The presentation favours a bleak, windswept aesthetic — coins, scrolls, blades, headgear and demon figures fill out the paytable, all styled to reflect a tense, war-torn world rather than a bright, celebratory one. Fire, tension and spiritual conflict run through the visual design throughout.
Winning combinations form by landing three to five matching symbols left to right across the 9 active paylines. This configuration runs on a comparatively steadier, medium-volatility math model, meaning the bigger swings are somewhat smoother here than in higher-volatility builds of the same title, while still offering genuine feature-driven upside through the Corrupted Hunter mechanic.
The Corrupted Hunter wild remains the centrepiece feature: it substitutes for all regular symbols, and whenever it forms part of a win it expands to cover the whole reel, revealing a random multiplier of up to 100x along with three stack meters. Each win it contributes to fills a stack, and once all three are full, a sticky respin sequence kicks in with the Corrupted Hunter locked in place, offering a genuine chance at a substantially bigger result. A separate Night of the Hunt bonus round can also be triggered from the base game, starting with three lives and populated only by bonus feature symbols or blanks — landing Bonus Demon symbols increases the round's overall multiplier before the accumulated total pays out once lives run out.
This build returns 96.3% to players at its top setting, matching the strong RTP of the wider Mortal Oath release, alongside a maximum win of 10,000x the stake. Stakes here run from 0.10 up to 100 per spin.
This Hacksaw Gaming configuration of Mortal Oath offers the same striking demon-hunter theme and Corrupted Hunter mechanic as the original build, but with a comparatively gentler medium-volatility setup that may suit players who want the feature depth without quite as extreme a variance.
