How wins work

  • The board has 6 reels × 4 rows, each reel set a little higher than the last like a hillside climbing to the right, with 4096 ways and no fixed paylines.
  • Matching symbols on 3 or more consecutive reels from the left pay; the 紅葉の大木 substitutes for regular symbols and appears on reels 2–6 only.
  • Now and then the autumn wind blows: 2–6 leaves land on different cells, each worth ×2/×3/×5/×10 for that spin (yellow, orange, red, crimson).
  • The leaves a way passes add up: passing ×3 and ×5 makes that way ×8, and a way that passes no leaf pays ×1. In the base game leaves last for that spin only.

Paytable

Values are total-bet multiples per way: a win = total bet × table value × the number of ways; a way that passes falling leaves is multiplied by the sum of the leaves it passes (×1 when it passes none). The 紅葉の大木 (wild) counts as a matching symbol. The paytable is the same source as in-game.

Special symbols

Great maple tree

Wild. Reels 2–6 only; substitutes for regular symbols, not for autumn letters. A leaf on its cell still adds to every way through it.

Autumn letter

Scatter. No connection required: 3 or more start Brocade autumn; 3 or more during the bonus add 3 spins.

Features

Autumn wind and falling leaves

The unseen hero is the wind: the maple branch in the foreground sways, and leaves spiral down onto the cells. A leaf sits on top of a cell while the symbol below still counts, and the leaves a way passes add up.

Brocade autumn — sticky leaves

3/4/5 autumn letters award 10/12/15 spins of Brocade autumn; 3 or more during the bonus add 3 spins. Leaves stick for the whole round; the wind may blow on any spin (1–3 leaves), and a leaf landing on a leaf adds to it (up to ×20 per cell).

The autumn front

On every spin of the bonus the red front climbs one reel from the foot of the hill (reel 1) toward the summit, turning those reels red: a leaf that lands on a red cell is worth ×2. The mountains behind turn red with it and the mist slowly clears.

The whole mountain turns red

The spin on which the front reaches the summit (reel 6) turns the whole mountain red: the stag on the peak lifts its head and calls, that spin's way wins are ×5, and from then on the wind blows on every spin.

Volatility and positioning

RTP 96.62%, volatility 5.75. The 37.67% hit rate counts any winning round; 12.49% of all rounds return at least the stake. The base game carries about 58% of the RTP; Brocade autumn comes about once every 68.20 spins. A single round is capped at 2,000× the bet and ends when it hits the cap. This describes the product's positioning and does not guarantee any single session.

Bonus buy

Pay 27.83× the bet to start 10 spins of Brocade autumn (bonus-buy RTP 96.63%), priced from the expected value of the purchase route and calibrated separately from regular play.

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.

Not a soul walks the autumn hillside—only the mountain wind, gust after gust.
Wherever a whirling maple leaf comes to rest, that cell glows with the season's multiplier.

I. A Sloping Path Through the Autumn Woods

In Japan, setting out into the hills to seek the turning foliage is called Momiji-gari—hunting the autumn leaves as though the shifting colours of the season were a prize hidden among the ridges. Accordingly, the reels step upward from left to right like a mountain trail climbing toward a misty peak.

Along the wooded slope gather the treasures of late autumn: a noble stag watching from the ridge, fragrant matsutake mushrooms beneath the pines, split chestnuts, and ripe persimmons, all framed by scarlet maple, golden ginkgo, crimson wax tree, and trailing ivy leaves.

II. The Unseen Wind and Falling Leaves

The quiet protagonist of the hillside is the autumn wind itself. Every so often a cool gust stirs the maple branch in the foreground and sends a flurry of yellow, orange, red, and deep crimson leaves spiralling down onto random cells across the sloping board.

Each fallen leaf rests lightly over its cell—including the wild great maple tree—without blocking the symbol beneath it from forming ways. Whenever a winning way passes through one or more leaf-strewn cells from left to right, all the leaf multipliers along that path add together.

III. Brocade Autumn and the Climbing Front

Receive enough autumn letters on the breeze and the hillside enters Brocade Autumn. Throughout these free spins, every leaf that lands stays on its cell for the entire round, and any new leaf that settles onto an already occupied cell adds its value directly to the stack.

Meanwhile, the autumn front advances one reel up the slope on every spin, starting from the foot of the hill on the leftmost reel. Every reel the front crosses turns deep red as the valley mist clears, and any fresh leaf landing on a red reel has its multiplier doubled on the spot.

IV. When the Whole Mountain Turns Red

The spin on which the advancing front reaches the rightmost summit reel heralds the Whole Mountain Red climax. Ridge upon ridge blazes scarlet at once, the stag on the peak lifts its antlers and calls across the valley, and every way win on that spin is multiplied.

From that summit moment onward, the autumn wind blows without fail on every remaining spin of the bonus, showering the slope with crimson and gold leaves. This seasonal walk through the hills is the game's theme rather than a promise: every spin's outcome is decided solely by the server's random number generator.
