How wins work

  • The board has 4 reels × 4 rows and 256 ways, with no fixed paylines. Matching symbols that appear on 3 or more consecutive reels from the left pay.
  • The four masks on the reels are clouded (bowed, weeping) and do not pay. After the reels stop, the stage light sweeps from left to right; each mask it touches looks up and turns lit (smiling), and lit masks are the high-paying symbols. The light's strength is each mask's chance to flip (every base spin is one of 25% / 50% / 75% / 100%).
  • The hannya is not on the reels: on a hannya spin, every ko-omote on reels 2–4 turns into the hannya (wild), substituting for regular symbols (not for curtains or clouded masks), and the whole spin's win is multiplied.
  • Curtains do not pay on ways: 3 or more anywhere start Jo-ha-kyū (free spins).

Paytable

Values are total-bet multiples: each way pays total bet × table value (the same numbers as the in-game paytable). The four masks pay only once turned to their lit (smiling) face; a clouded (bowed) mask does not pay and is not replaced by the hannya. On a hannya spin the whole spin's win is multiplied.

Special symbols

Hannya

Wild. Not on the reels: on a hannya spin every ko-omote on reels 2–4 becomes the hannya, substituting for regular symbols (not for curtains or clouded masks); the whole spin's win is multiplied (×2 in the base game, ×2 / ×3 / ×5 in Jo-ha-kyū).

Agemaku curtain

Scatter. No connection required: 3 or more start Jo-ha-kyū; 3 or more during the bonus add 2 spins.

Features

Light and shadow

After every spin the stage light sweeps from left to right, and each clouded mask it touches looks up one by one, turning from a weeping face into a smiling one. A brighter light flips more: every base spin is lit at 25% / 50% / 75% / 100%, and the light bar on the left shows that spin's strength.

A moment of grudge

Now and then the stage darkens in the base game: every ko-omote on reels 2–4 (lit or clouded) grows horns and becomes the hannya wild, and that spin's win is ×2. The great mask above the stage turns hannya and laughs at the same moment.

Jo-ha-kyū

3 or more curtains award 12 spins of Jo-ha-kyū; 3 or more during the bonus add 2 spins. Each act is brighter than the last: Jo (spins 1–4) at 50% light with the hannya ×2; Ha (spins 5–8) at 75%, ×3; Kyū (spin 9 onward) fully lit, ×5 — and the first spin of Kyū always turns hannya.

Grudge meter

During Jo-ha-kyū, each mask still weeping at the end of a spin adds one mark of grudge. At 10 marks the next spin turns every ko-omote hannya at that act's multiplier, and the meter resets. The dimmer the light, the faster the grudge builds — even a dark spin has its use.

Hashigakari preview

During Jo-ha-kyū, the bridgeway on the left shows the top three symbols of reel 1 for the next spin before it begins — what you see is real. When the next spin starts, they walk down the bridgeway onto the stage.

Bonus buy

Pay 86.27× the bet to start Jo-ha-kyū (12 spins). The price follows the expected value of that purchase route (bonus-buy RTP 96.32%) and is calibrated separately from regular play.

Volatility and positioning

Volatility 8.94. The 28.41% hit rate counts any winning round; 14.51% of all rounds return at least the stake. The base game carries about 50% of the RTP, with the light sweep giving every spin a swing; Jo-ha-kyū comes about once every 171.96 spins. A single round is capped at 1,300× the bet and ends when it hits the cap. This describes the product's positioning and does not guarantee any single session.

The story

Fiction and adapted settings written by Akitsora Gaming for this title, including invented dialogue and events. This is not a historical or folklore reference. The rules and specification tables define the gameplay and math.

A polished cypress stage beneath the painted pine of the back wall.
Tilted down, a mask weeps; tilted up, it smiles—the stage light alone decides which face it wears.

I. Clouded and Lit Masks on the Cypress Stage

Inside the hushed Noh theatre, an ancient green pine stretches across the back wall while the hashigakari bridgeway leads from the mirror room onto the main stage. To the sharp calls of the kotsuzumi drum, the ōtsuzumi drum, and the piercing nōkan flute, a masked performer wearing an embroidered kazura-obi headband glides across the polished cypress boards.

A carved Noh mask has only one wooden face, yet its emotion shifts with the angle of light: bowed into shadow it is clouded and weeping; raised into the beam it is lit and smiling. On every spin, Okina, Ko-omote, Shōjō, and Ōtobide land bowed in sorrow until the stage light sweeps from left to right and lifts their faces into high-paying smiles.

II. A Sudden Moment of Grudge

The stage beam changes strength from spin to spin, ranging from a dim glimmer to a full blaze across the boards; the brighter the beam, the more clouded masks look up and smile. Yet every so often in the base game, just as the reels settle, the entire theatre plunges into sudden darkness and the drums fall silent.

In that breathless moment of grudge, the great mask suspended before the painted pine bursts into laughter, and every Ko-omote across the central reels—whether smiling in the light or weeping in shadow—grows golden horns and transforms into the wild Hannya, multiplying the entire spin's harvest.

III. The Three Acts of Jo-ha-kyū

When the five-coloured agemaku curtain is swept upward at the entrance, the performance enters the classic three-act rhythm of Jo-ha-kyū. Throughout the bonus, the bridgeway on the left previews the top three symbols that will walk onto the first reel on the very next spin, letting the audience see who approaches the stage before the reels even turn.

True to theatrical tradition, both the stage light and the Hannya's multiplier build from act to act: Jo opens in measured half-light, Ha brightens the tempo, and Kyū floods the entire stage in full brilliance, flipping every mask to its smiling face and opening with a guaranteed Hannya transformation.

IV. Tears Gathered into Golden Horns

Even a dimly lit spin serves the drama during Jo-ha-kyū. Every mask that remains unlit and weeping at the end of a spin adds a mark to the grudge meter; once the meter is full, the very next spin plunges the stage into shadow and turns every Ko-omote on the middle reels into a horned Hannya at the current act's multiplier.

With her porcelain-white visage, crimson lips, and gleaming golden horns, this auspicious Hannya brings the dance to its climax before the flute fades into silence. This interplay of mask and light is the game's theme rather than a promise: every spin's outcome is decided solely by the server's random number generator.
