Onis Wrath

Onis Wrath is a Japanese mythology and horror slot from Spark Studios with an RTP of 96.5%, high volatility and a maximum win of 10,000x. The game uses a 5x5 grid with 3,125 ways to win.

The Ofuda Seal wild symbol substitutes for any winning symbol and grows more powerful when it lands on a highlighted reel. It can expand and then summon an Oni effect, allowing a single symbol to transform the board in different ways based on which effect triggers.

Torii Gate scatters launch the bonus modes when landing in groups. Three Torii Gate scatters trigger Night Parade, four trigger Hell's Gate and five unlock Onigami. During active bonuses, the same scatter counts can retrigger additional free spins.

Night Parade awards 10 free spins and can be triggered by 3 Torii Gate scatters or purchased for 100x play. The bonus features an elevated wild-on-highlight rate so highlighted reels land more often, creating better chances for Oni effects to stack.

Hell's Gate gives 10 free spins and triggers with 4 Torii Gate scatters or via a 250x play purchase. It provides the highest natural wild rate on highlighted reels plus 1 guaranteed wild every spin.

Onigami is the top bonus mode, unlocked by 5 Torii Gate scatters or bought for 500x play. It awards 10 free spins with 2 guaranteed wilds on highlighted reels each spin and grants access to the strongest Omen Oni multiplier table.

Wrath Oni spreads wilds to neighbouring reels when activated, replacing the symbols that landed there. This board-changing effect builds Ways wins by connecting more positions across adjacent reels after the spin has stopped.

Omen Oni adds spin-level multipliers after a wild lands on a highlighted reel, ranging from modest values to very large ones in Onigami mode. It does not change symbols directly but can heavily raise the value of a strong Ways hit.

Storm Oni fires lightning across the board and turns random cells wild, sometimes stamping multipliers onto those converted cells. The unpredictable placement of lightning strikes brings greater volatility than standard wild behaviour.

Trickster Oni upgrades neighbouring symbols by one tier, strengthening potential Ways matches before the win is counted. On a strong spin, it can also become a full wild stack.

Phantom Oni appears during free-spin rounds as a haunted wild stack. It supports bonus rounds by adding more wild presence without focusing on board upgrades or spread mechanics.

Whispers is a per-spin feature activated from the bonus menu for 3x play. It raises the chance of triggering a bonus on each spin and stays active until switched off.

Spark Spins is a per-spin feature costing 300x play. One spin can send wild reels erupting across the board, usually two, creating a dramatic single-spin burst with multiple wilds and Oni effects rather than entering a free spins round.
