RTP verificationExact solution: uncapped expectations give RTP 96.7300%; cap loss is checked with conservative analytical bounds and numerical tolerance is included. Each hardness is calibrated separately; base play and bonus buy disclose 96.73% to 2 decimal places. This rounded disclosure does not assert identical exact capped expectations; cap and numerical bounds still apply.

Game math specifications and the paytable are read at build time from the definitions shared with the server code. See Math version for the configuration shown; confirm any other version or operator-specific settings separately.

How wins work

  • The bowl has 3 independently rotating rings, each with 8 segments. Only its 24 defined paylines count: 8 radial, 8 clockwise spiral, and 8 counterclockwise spiral lines.
  • A line matching the same ingredient across 3 rings, read from the bowl's centre outwards, pays. Golden ajitama Wilds substitute for regular ingredients, not kaedama scatters. Wins on different lines are added.
  • During free service and the kaedama tail, naruto reveals a fresh multiplier for the current spin's line wins. It does not accumulate across spins; revealing a multiplier alone is not a win.
  • Kaedama scatters pay anywhere: 3/4/5+ award ×2/×10/×50 total bet. More scatters pay more but do not lengthen the chosen free service.

Paytable

Values are total-bet multiples for one line: line win = total bet × displayed multiple. Free service and the kaedama tail also apply the current naruto multiplier. Scatter awards are separate and are not multiplied by naruto. Combined awards remain subject to the round cap.

Special symbols

Golden ajitama — Wild

Substitutes for regular ingredients, not kaedama scatters, and has no symbol award of its own. When the chef torches the board in the base game, seared chashu also turns into Wilds.

Kaedama — scatter

Pays anywhere according to the paytable. 3+ in the base game opens free-service selection. Ordinary free-service scatters pay only; 3+ in the tail restart the same hardness. Naruto does not multiply scatter awards.

Features

Torched chashu Wilds

When the chef torches in the base game, the board's chashu becomes golden ajitama Wilds. Line awards use the resulting board. The flame meets the bowl and the affected ingredients glow before becoming Wilds.

Pick hardness, choose the swing

3+ kaedama scatters in the base game let the player choose noodle hardness before free service. The 5 hardnesses are calibrated separately and each discloses 96.73% RTP, rounded to 2 decimal places. Harder noodles mean fewer spins, higher naruto multipliers and bigger swings; the relative volatility below compares only the 5 hardnesses in this game.

Yawa — soft

20 free spins; naruto values ×1, ×2, ×3. Relative volatility 1/5 within this game.

Normal

14 free spins; naruto values ×1, ×2, ×3, ×4, ×5. Relative volatility 2/5 within this game.

Kata — firm

10 free spins; naruto values ×2, ×3, ×4, ×5, ×6, ×7, ×8, ×9, ×10. Relative volatility 3/5 within this game.

Barikata — extra firm

7 free spins; naruto values ×3, ×5, ×8, ×10, ×15, ×25. Relative volatility 4/5 within this game.

Kona — very firm

5 free spins; naruto values ×5, ×10, ×15, ×25, ×50. Relative volatility 5/5 within this game.

Kaedama tail — another bowl

After the selected free service, 5 kaedama-tail spins use the same hardness and naruto distribution, with more chances of a kaedama combination. Scatters during ordinary free service pay only, without adding or restarting spins. Only 3+ scatters in the tail stop the unused tail spins and restart the full chosen service. Hardness stays unchanged without another selection, and the restarted service is followed by its own tail.

Buy free service

Bonus buy costs total bet ×56.517, priced from feature expected value. Select hardness before payment; cancelling the choice buys nothing. Purchased play discloses 96.73% RTP and is verified separately from natural triggers.

Resume and round cap

Reconnecting restores the chosen hardness, board and actual remaining spins. An unchosen round still awaits selection; if the server completes it through recovery, it uses Normal. The entire round, including free service and kaedama, is capped at 5,000× total bet. Reaching the cap settles immediately without unused spins or another restart.

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 single lantern warms the street corner as rich broth simmers through the night.
The chef wipes his hands beneath the noren, waiting for your call on the noodles.

I. The Midnight Street Stall

Down a quiet city lane long after midnight, clouds of savory white steam rise from a wooden yatai ramen cart parked beside the curb. Beneath the indigo noren curtain, the master chef tends a simmering cauldron of creamy tonkotsu broth, setting down a crimson lacquer bowl whose rich aroma of roasted garlic and tare soy draws hungry night owls from afar.

Instead of ordinary vertical reels, the ramen bowl spins across three concentric rings of toppings turning independently from the center outward to the rim. Seared chashu, braised pork belly, crisp bamboo shoots, wood-ear mushrooms, and sheets of nori whirl around the steaming broth, paying along radial lines and clockwise or counterclockwise spirals across the dish. Late-night regulars lean in beneath the warm streetlamp glow, watching the master chef orchestrate every boiling pot with effortless precision.

II. Seared Chashu and Golden Eggs

Half the joy of taking a wooden counter stool at the stall is watching the chef work his fire up close. During base-game spins, the master may suddenly reach for his kitchen blowtorch and sweep a roaring jet of flame across every piece of seared chashu resting in the bowl, filling the night air with the sizzle of caramelized pork.

As the orange embers fade from the rim, each torched slice transforms into a glowing Golden Ajitama Wild—a soft-boiled marinated egg that substitutes for regular toppings across all three rings. Every burst of flame follows the true symbols that landed in the bowl, linking radial and spiral paylines in a single fiery stroke across the broth. Late-night regulars lean in beneath the warm streetlamp glow, watching the master chef orchestrate every boiling pot with effortless precision.

III. Noodle Firmness and the Naruto

When enough Kaedama scatters land anywhere in the bowl, the chef pauses before free service to ask how firm you take your noodles tonight. You choose the pace of the meal yourself: gentle soft Yawa with the longest service, balanced Normal, toothsome Kata, brisk Barikata, or ultra-firm Kona-otoshi lifted almost immediately from the boiling pot into the bowl. Savory clouds of pork-bone steam rise beneath the red cloth curtains as chopsticks clatter and bowls slide down the polished counter.

Firmer noodles serve fewer bowls in the round but unlock far higher multiplier peaks on the swirling pink-and-white naruto fish cake at the center of the dish. On every free spin, the naruto wheel spins and stops in the broth to reveal a fresh spin multiplier that seasons all line wins scored on that steaming bowl. Late-night regulars lean in beneath the warm streetlamp glow, watching the master chef orchestrate every boiling pot with effortless precision.

IV. The Kaedama Encore Bowl

At a traditional Hakata street stall, no seasoned regular finishes the broth on the first serving—you always save half a bowl of hot soup to call for kaedama, a fresh ball of wheat noodles dropped straight into the broth. Here, once your chosen free service ends, the round flows straight into the Kaedama Tail for a closing encore. Savory clouds of pork-bone steam rise beneath the red cloth curtains as chopsticks clatter and bowls slide down the polished counter.

During these closing tail spins, the bowl keeps your chosen noodle firmness and naruto multiplier wheel while boosting the chance of landing Kaedama scatters across the rings. Gather enough scatters before the tail runs out, and the chef tosses a fresh batch into the pot, restarting the entire free service at the very same hardness. Late-night regulars lean in beneath the warm streetlamp glow, watching the master chef orchestrate every boiling pot with effortless precision.
