How wins work

  • The grid is 3 reels × 3 rows with 5 fixed lines (three across, two diagonals), counted from the leftmost reel.
  • Watermelon and Bell pay with all 3 reels on a line; a Cherry on the leftmost reel pays on every line it sits on.
  • When several lines win on the same spin, each is calculated separately and added. Three Replays on a line: a free re-spin within the same round.
  • When the shisa's eyes light up on the roof, a bonus is confirmed: BIG BONUS (8 spins) leads into high-continuation RUSH (10 spins), while a screen-freeze Heaven RUSH multiplies every bonus along the streak (up to ×10).

Paytable

Values are the symbol multiplier in: line win = (bet ÷ 10) × symbol multiplier. Watermelon and Bell need all 3 reels; Cherry only needs the leftmost reel (one, two or three in a row pay the same). Red 7, BAR and Replay are not in this table — lining them up starts a bonus or a free re-spin, see the features below.

Special symbols

Red 7

On a line = BIG BONUS (natural alignment). It is also what lines up in the middle after a BIG lot hits.

BAR

On a line = REG BONUS (natural alignment).

Shisa 7

Appears only in a Heaven alignment: after a freeze, this is what lines up in the middle.

Replay

On a line: a free re-spin within the same round. During RUSH it does not use up a RUSH spin.

Features

The notice lamp: the shisa's eyes

Every base-game and RUSH spin also draws a bonus lot, independent of the reels. When it hits, the eyes of the two shisa on the roof light up — lit means the bonus is confirmed. Sometimes they light at once, sometimes at the start of the next spin (late notice), and the reel backlight may go dark for a beat first. On the next spin the 7s (or BARs) line up in the middle row and the bonus begins; three Red 7s or BARs landing on their own count too. A bonus comes roughly once every 111.90 rounds.

BIG, REG and RUSH

BIG BONUS: 8 spins, then RUSH. REG BONUS: 4 spins; a REG from the base game ends there. RUSH: 10 spins with a far higher bonus chance on every spin — a hit extends the streak, and once that bonus is played RUSH refills to 10; a REG inside RUSH returns to RUSH too. The continuation rate (the chance of another hit within one RUSH) is about 47.13%.

Freeze — Heaven RUSH

You press spin and the whole screen freezes; in the dark only the shisa's eyes slowly light up — that is a Heaven BIG BONUS. Heaven RUSH follows: a continuation rate of about 82.94%, and every bonus pays a Heaven multiplier set by the streak (×1 for streaks 1–2, ×2 for 3–4, ×3 for 5–6, ×5 for 7–9, ×10 from the 10th in a row). Regular RUSH has no multiplier.

Five lamp colours — the Eisa dancers

The longer the streak, the higher the eye colour: blue, yellow, red, gold, rainbow. During a bonus the backdrop turns to a festival night and Eisa dancers (Okinawa's Obon dance) appear in the sky to the upper left and right — the higher the lamp, the more dancers. The data counter (spins, BIG, REG, best streak) sits left of the reels, like the one above a real machine.

Medium volatility — a cap you can reach

Volatility 5.37. Hit rate 26.16% counts rounds with any win; 21.70% of all rounds return at least the stake. The round cap of 3,000× is only reachable with Heaven RUSH's top multipliers — the RTP is an exact solution (every outcome's probability computed exactly), and the cap's probability is part of it. No free spins, 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.

Upon Ryukyu’s red-tiled roofs sit two guardian lions—one mouth open, one closed.
When their eyes blaze in the tropical night, the drums of the streak begin to pound.

I. Twin Guardians on the Roof

Across the sun-drenched islands of Okinawa, traditional red-tiled roofs are watched over by a pair of earthenware shisa guardian lions. The open-mouthed a welcomes good fortune in from the warm sea breeze, while the closed-mouthed un seals that blessing safely inside the home, standing motionless above the eaves through coastal wind and tide. Lantern light shimmers across the coralstone courtyard as tropical sea breezes carry the lively rhythm of island drums into the night.

This classic three-reel pachislot sets the twin guardians upon the two corners of its cabinet roof, looking down over spinning watermelons, golden bells, Cherries, and Replay emblems across five fixed lines. Beside the reels sits an authentic hall data counter tracking total spins, bonuses, and peak streaks just like a neighborhood island parlor machine. Between the vermilion roof tiles and the moonlit surf, the festive spirit of Okinawa dances through every corner of the board.

II. Eyes That Confirm the Bonus

In Japanese pachislot tradition, the entire drama of a spin rests on a single notice lamp: the instant it glows, a bonus is locked in without a shadow of doubt or guesswork. Here, the unlit grey eyes of the two rooftop shisa serve as that unmistakable island beacon watching every single turn of the reels. Lantern light shimmers across the coralstone courtyard as tropical sea breezes carry the lively rhythm of island drums into the night.

Sometimes their eyes flare the moment the spin begins; at other times the reel backlight dims in a sudden blackout before a late notice ignites at the start of the following turn. On the next spin, Red Sevens or BARs snap across the center line to launch the bonus and open the door to high-tempo RUSH streaks. Between the vermilion roof tiles and the moonlit surf, the festive spirit of Okinawa dances through every corner of the board.

III. Festival Nights and Eisa Drums

During the old-calendar Obon season in late summer, youth troupes across Okinawa march through lantern-lit village streets beating barrel drums and handheld paranku, dancing the spirited Eisa to the lively pluck of sanshin strings to honor and send off their ancestors beneath the warm southern stars. Lantern light shimmers across the coralstone courtyard as tropical sea breezes carry the lively rhythm of island drums into the night.

As soon as a bonus begins, the coastal dusk transforms into a blazing festival night and the cabinet’s bingata stencil cloth shifts from warm yellow to deep ocean teal. With every consecutive streak, the shisa’s eyes climb through blue, yellow, red, gold, and rainbow while more Eisa dancers fill the night sky on both sides of the roof. Between the vermilion roof tiles and the moonlit surf, the festive spirit of Okinawa dances through every corner of the board.

IV. The Screen Freeze into Heaven

Every island player waits for one rare, heart-stopping moment at the cabinet: the Freeze. You press spin and the entire machine suddenly halts in its tracks; the cabinet lamps plunge into total darkness until only the four eyes of the shisa slowly kindle in the gloom, heralding a Heaven BIG BONUS. Lantern light shimmers across the coralstone courtyard as tropical sea breezes carry the lively rhythm of island drums into the night.

Emblazoned with the special Shisa Seven alignment across the middle row, Heaven RUSH carries a surging continuation rate and a Heaven multiplier that climbs higher with every linked bonus in the streak. Under rainbow eyes and thunderous Okinawa drums, the guardian lions deliver their grandest island blessing. Between the vermilion roof tiles and the moonlit surf, the festive spirit of Okinawa dances through every corner of the board.
