Mortal Oath is a dark Sengoku-era slot from Foxhound Games featuring high volatility gameplay and a maximum win potential of 10,000x your stake. Combining expanding wild multipliers with a complex bonus system, it delivers intense, feature-driven action.
Mortal Oath is played on a 5x3 reel layout with 9 fixed paylines. Winning combinations are formed by landing 3 to 5 matching symbols from left to right across active paylines. The game operates on a highly volatile math model designed for larger but less frequent payouts.
Wild symbols substitute for all regular paying symbols, and landing five wilds on a payline awards 20x the total bet. The base game also features the Corrupted Hunter symbol, which acts as an expanding wild when part of a win. When triggered, it expands to cover the entire reel, displays a random multiplier between x2 and x100, and includes three stack meters. Each time it participates in a winning line, stacks fill. When all stacks are filled, a respin is triggered where the Corrupted Hunter remains sticky.
Set during a supernatural interpretation of Japan’s Sengoku era, Mortal Oath presents a bleak, windswept battlefield where demons and divine forces collide. The atmosphere is dark and dramatic, replacing traditional bright Asian motifs with a more intense aesthetic. Symbols include coins, scrolls, blades, headgear, and various demon figures, all styled to reflect the war-torn setting. The overall presentation emphasizes tension, fire, and spiritual conflict.
During the bonus, Demon symbols become sticky and activate multiplier values. Yellow Demons carry x1–x3, Blue Demons x4–x6, and Green Demons x7–x9 multipliers. Filling the entire grid with Bonus Demon symbols awards an additional 500x payout added to the total multiplier.
Additional bonus symbols include:
Divine Retribution activates if all lives are lost while an activated Guardian Statue is present. It doubles all Bonus Demon multipliers, adds them to the total multiplier, clears sticky symbols, and resets lives to three. It can trigger once per bonus round.
