Mortal Oath
Mortal Oath transports players to Japan’s brutal Sengoku period, a war-torn era where demon hunters battle supernatural forces across a desolate, wind-swept realm. Unlike cheerful Asian-themed slots, this 10,000x max win game embraces darkness with fire-lit visuals, ominous symbols, and a horror-tinged atmosphere where “reality and fantasy collide.”
Each spin carries tension as warriors clash against demonic entities, with free spins and bonus features amplifying the intensity. Foxhound Games delivers a mythic experience where every moment could summon fortune or flame. For players seeking risk and dramatic payouts, Mortal Oath offers an unyielding journey through a land ruled by fear.
Mortal Oath Gameplay and Mechanics
Mortal Oath unfolds across a 5×3 grid with 9 fixed paylines in the base game, where winning combinations form on adjacent reels. The action intensifies through four core features. Special Symbols include expanding wilds that fill entire reels and multiplier wilds that boost wins. The Corrupted Hunter triggers respins with sticky wilds for increased payout potential. Night of the Hunt is the primary bonus round, awarding free spins with enhanced modifiers and higher-value symbols. For instant access, the Buy Bonus option allows players to purchase entry into the feature round directly. This mechanically rich design delivers the aggressive, high-volatility experience that defines Mortal Oath’s demonic battlefield.
Mortal Oath Theme and Visuals
Mortal Oath plunges players into Japan’s Sengoku period, a chaotic era of civil war where demon hunters wage war against supernatural forces. Unlike cheerful Asian-themed slots, this dark interpretation presents “a land ruled by fear and flame,” where reality and fantasy collide across desolate battlefields.
The visuals embrace a haunting aesthetic: fire-lit skies cast crimson glow upon wind-swept plains, while ominous symbols, demonic masks, cursed blades, and warrior crests materialise against shadow-drenched reels. Character art depicts grizzled hunters locked in eternal combat with grotesque oni demons, their struggles illuminated by flickering torchlight.
The atmospheric soundtrack amplifies tension with traditional Japanese instrumentation twisted through eerie modern composition. Every visual element reinforces the mythic struggle between mortal and demon, creating an immersive world where darkness reigns, and fortune favours the brave.

The ultimate goal is to land the maximum win potential of 10,000x the total bet.
Mortal Oath Slot Features
Step into the darkness where demon hunters clash with supernatural forces and fortunes are forged in fire. Mortal Oath delivers tension, terror, and tremendous win potential. Let’s look at the features that make the game potentially rewarding for all players.
Corrupted Hunter
The Corrupted Hunter symbols serve as wilds that appear exclusively in the base game, expanding to cover entire reels only when part of at least one winning line. Upon expansion, each displays a random multiplier (2x to 100x) and arrives with three empty stacks.
Every time a Corrupted Hunter contributes to a winning line, one stack fills; multiple wins in the same spin can fill several stacks simultaneously. Once all three stacks fill for an individual hunter, it triggers a respin. During this respin, the Corrupted Hunter remains sticky while other reels spin again, offering fresh win potential. New Corrupted Hunters cannot land during respins.
When multiple hunters fill their stacks, respins activate one at a time from leftmost to rightmost. If multiple Corrupted Hunters contribute to a win, their multipliers combine before application. Only one hunter appears per reel, with a maximum of three per spin, making this feature a volatile battleground for substantial rewards.
Demon Symbols
Demon symbols serve dual purposes across Mortal Oath’s gameplay modes. In the base game, they behave as regular high-paying symbols without multipliers, simply contributing to standard winning combinations. Their true power awakens during the bonus game. Here, Demon symbols land with active multipliers and remain sticky on the grid throughout the feature. Each demon type carries distinct multiplier ranges:
- Yellow Demon: 1x, 2x, or 3x
- Blue Demon: 4x, 5x, or 6x
- Green Demon: 7x, 8x, or 9x
These sticky demons accumulate on the reels during free spins, with their multipliers combining to create substantial win potential. The escalating value of higher-tier demons rewards players who fill the grid with these supernatural entities, transforming the bonus round into a truly explosive battleground where fortunes multiply with each new arrival.
Night Of The Hunt
Land 3 Bonus Scatter symbols at the same time in the base game to activate the Bonus Feature. The grid transforms entirely, and only non-paying symbols and bonus feature symbols appear. The journey begins with a Total Multiplier starting at 0, which grows progressively as Bonus Demon symbols and other special symbols land.
The feature grants three refilling lives, each representing one spin. Every time a bonus symbol lands, lives reset to three. When all lives are consumed without reset, the feature ends and the accumulated Total Multiplier applies to the final bet amount.
A thrilling grid fill mechanic rewards players who fill every position with Bonus Demon symbols: a massive 500x multiplier instantly adds to the Total Multiplier, then concludes the feature. This creates intense anticipation with every spin, as players chase the ultimate payout through demonic possession of the reels.
Collector Symbol
The Collector symbol collects all Bonus Demon multipliers on the grid and adds them to itself without removing them from the original symbols. The Collector symbol acts as a Bonus Demon symbol and stays sticky. If the Collector lands together with the Gun ability symbol on the same spin, the Gun ability symbol will not target the Collector. If the Collector lands first on the grid with no other Bonus Demon symbols, it will receive a 1x multiplier by default.
Gun Ability Symbol
The Gun Ability symbol targets 1 Bonus Demon symbol and fires up to 3 times. Each shot doubles the multiplier of the targeted Bonus Demon symbol. Only one Bonus Demon symbol can be targeted per Gun Ability symbol. If the Gun ability lands first on the grid with no other Bonus Demon symbols, it will not perform any action.
Gates of Hell Symbol
The Gates of Hel symbol lands with a 5x multiplier and stays on the grid. Each time a bonus feature symbol lands, the multiplier doubles. Once a life is consumed, the Gates of Hell multiplier is added to the Total Multiplier bar and the Gates of Hell symbol is removed on the next spin. Only one Gates of Hell symbol can be active at a time.
Guardian Statue Symbol
The Guardian Statue symbol lands with 4 empty stacks, one of which fills immediately. Fills one stack each time a bonus feature symbol lands. If a life is lost before all 4 stacks are filled, the Guardian Statue symbol is removed on the next spin. Once all 4 stacks are filled, the Guardian Statue stays sticky and can trigger Divine Retribution.
The Divine Retribution triggers when all 3 lives are consumed, and an activated Guardian Statue is on the grid. Doubles all Bonus Demon multipliers, adds them to the Total Multiplier bar, clears the grid of any sticky symbols, and refills lives back to 3. Can only trigger once per Bonus Feature game
Special Symbols
The Wild: It substitutes for all symbols in the paytable, and it appears only in the base game. The Wild awards 20x the bet for 5 matching combinations.
The Bonus Scatter does not appear during the bonus game.
Bonus Buy
Players can instantly access the game features by activating the BonusHunt FeatureSpins and Corrupted Hunter FeatureSpins for 3x the bet and 50x the bet, respectively. Players can also buy Night of the Hunt at 100x the bet. Each Bonus Buy feature comes with market-average RTP at 96.3%, 96.35%, and 96.38%, respectively.
| Feature | Description |
| High-paying symbol | Scroll, Sword, Helmet and 3 warrior Characters. They award between 1.5x the bet and 10x the bet for 5 matching combinations. |
| Low-paying symbol | Bronze, Silver, and Gold shields. They award 1x the bet for 5 matching combinations. |
