How wins work

  • A classic 3-reel machine: you can see the neighbouring symbols, but only the middle line pays. Three of the same symbol on the middle line wins.
  • The ×2/×3 enamel signs are wild and substitute for 7s, bells and BARs; every one on the line multiplies (three ×3 = ×27).
  • Lamune pays anywhere on the middle line; a winning stick gives a free re-spin; lottery tickets trigger the prize draw.
  • Landing lottery tickets on the middle line awards 1, 3 or 10 turns of the octagonal prize drum on the next spin, where each ball dropped pays a total-bet multiplier by colour up to the ×1,000 rainbow grand prize.

Paytable

Values are multiples of the total bet: three in a row on the middle line wins total bet × the value (the same numbers as the paytable on the machine). Wild multipliers on the line multiply; a line of three wilds pays as the red 7 times the multipliers.

Special symbols

×2 / ×3 sign

Wild, substitutes for 7s, bells and BARs (not lamune, sticks or tickets). Multipliers on the same line multiply.

Lamune

Pays anywhere on the middle line: 1, 2 or 3 bottles pay ×2.5, ×5.2 or ×15.1 (total bet), with no multiplier.

Winning stick

On the middle line it means "one more": a free re-spin. With tickets on the same spin, the draw comes first and the re-spin follows.

Lottery ticket

1, 2 or 3 on the middle line → 1, 3 or 10 draws on the next spin. Every draw drops a paying ball (at least ×1).

Features

Fukubiki — the ball's colour is the prize

1, 2 or 3 tickets on the middle line give 1, 3 or 10 draws on the next spin. The player taps the drum (or waits a moment for it to turn), and one ball drops each time: white ×1, yellow ×3, blue ×5, green ×10, red ×30, gold ×200, rainbow ×1,000 (multiples of the total bet). A draw happens about once every 8.95 rounds.

An honest window

While the drum turns, the ball colour in the outlet window only ever climbs, and the colour it stops on is the result — no flashing gold before falling back to white. A striped ball means "draw again": one more ball drops for that draw.

Multiplying wilds

The ×2/×3 signs substitute for regular symbols and their multipliers multiply on the line: ×2 and ×3 = ×6, three ×3 = ×27. A line of three wilds pays the red 7's 15× times the multipliers — up to 405×.

Lamune and the winning stick

Lamune pays anywhere on the middle line: 1, 2 or 3 bottles pay ×2.5, ×5.2 or ×15.1 (wilds do not substitute). Winning stick: "one more!" — the spin pays as usual, then re-spins at no cost.

Small, frequent lines

Volatility 2.71, capped at 2,000×. Hit rate 29.10%; 29.10% of all rounds return at least the stake (even the smallest prize is no lower than the bet). The base game carries about 60% of the RTP; the big moments come from the gold and rainbow balls. No bonus buy.

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.

Year-end banners flutter above the Showa shopping arcade on lottery day.
Give the octagonal wooden drum a turn, and the ball that drops reveals your fortune.

I. The Arcade at Year’s End

In the nostalgic decades of the Showa era, every December transformed neighborhood shopping streets into warm corridors of red-and-white triangular bunting. Beneath the covered arcade roof, the striped awnings of the greengrocer, the fishmonger, and the stationer stood side by side, their shop signs painted simply with an apple, a fish, and a pencil just like the old two-color handbills.

Every small household purchase all winter long came with a paper fukubiki lottery ticket tucked carefully into a coat pocket for the grand year-end sale. This classic three-reel machine captures that exact street corner at dusk, where every spin focuses purely on the single payline running straight across the center window. Every turn of the wooden crank fills the neighborhood shopping street with warm laughter and year-end anticipation.

II. Enamel Signs and Lamune Bottles

Framed inside the vintage reel window are timeless parlor icons—Red Sevens, brass bells, BARs, and winter mandarins—joined by weathered enamel multiplier signs bolted to the tin. Acting as wilds on the center line, these signs substitute for classic symbols and multiply against one another whenever more than one helps complete a win across the middle row. Cheerful brass bells ring out through the covered arcade as families gather around the red-draped prize table in winter coats.

Alongside them sit glass bottles of Lamune marble soda, which pay an instant prize whenever even a single bottle lands anywhere on the middle line without needing a full trio, and wooden winning popsicle sticks stamped with a free-encore mark that pays the current spin as usual and immediately grants a no-cost respin. Every turn of the wooden crank fills the neighborhood shopping street with warm laughter and year-end anticipation.

III. The Octagonal Wooden Drum

Whenever one, two, or three Lottery Tickets stop on the center line, the next spin steps up to the neighborhood prize table draped in red-and-white festival cloth. There stands the octagonal wooden garapon drum, with the merchant association chairman waiting brass bell in hand for you to grasp the wooden handle and turn the crank. Cheerful brass bells ring out through the covered arcade as families gather around the red-draped prize table in winter coats.

As the wooden drum rattles around on its stand, the honest preview window at the spout shows the ball color climbing step by step without ever teasing a high color and dropping back down to white. Where the window stops is the exact prize ball that rolls into the wooden tray—while a striped ball grants an immediate extra draw. Every turn of the wooden crank fills the neighborhood shopping street with warm laughter and year-end anticipation.

IV. Gold Balls and the Chairman’s Bell

Every ball that drops—from white, green, blue, and red up to the top prize tiers—pays a guaranteed multiple of the total bet. If you look closely at the cabinet and the street behind it, you will notice that not a single drop of gold paint is used anywhere on the machine: all the gold is saved for the Gold Ball.

When a Gold Ball tumbles out into the wooden tray, the chairman freezes in astonishment before throwing both arms skyward in a banzai cheer; and when the rare Rainbow Ball appears, the entire shopping street rushes out under a shower of paper confetti and ringing bells to celebrate the year’s grandest prize. Every turn of the wooden crank fills the neighborhood shopping street with warm laughter and year-end anticipation.
