2026/01/14 Updated v1.5
Bug fixesImplemented the R18 VN scenario in gallery mode. You can view it in
gallery mode.
Fixed bug
1. Red Dora is also double counted as back Dora
Symptom: When you have a red Dora, the number of Dora is displayed
higher than it actually
Cause: The countDora function in yakuChecker.ts was counting
the red Dora when calculating the Dora
Fix file: src/logic/yakuChecker.ts
2. Hidden bar options are broken at the bottom of the screen and cannot be seen
Symptom: In a situation where dark bars can be hidden, the selection UI is displayed at the bottom of the screen and is cut
off
Cause: The CSS of .ankan-options was
placed under the hand in relative position
Fix file: src/components/MahjongBoard_v2.css
3. Saving / Loading Boss Rush resets progress
Symptom: After defeating an enemy in Boss Rush, if you save and return to the title and resume, you will have
a rematch with the same enemy
Cause: handleContinue did not
transition to the correct screen according to the stat
Fix file: src/components/BossRushSelect.tsx
4. Boss Rush state leaks into normal mode
Symptom: After saving Boss Rush and returning, when you start a normal game, it ends immediately without playing mahjong and goes into
boss rush mode
Cause: bossRushStore.isActive was not
reset at the start of normal game
Fix file:
– src/stores/bossRushStore.ts – added pauseBossRush()
– src/App.tsx – Call
pauseBossRush() at the start of normal game
5. The maximum level notation in the strategy information is incorrect
Symptom: The maximum level is displayed as 99 in the strategy information, but it is actually 100
Fix file: src/i18n/locales/en/strategyGuide.ts
Fix contents: The maximum level is 99 → The maximum level is 100
6. Freeze at the end of the East Wind Battle (high frequency) Symptoms
: Freezes
when the East Wind Battle ends normally (4 stations fulld), not Tobi Frequency of
occurrence: Reported
3 times a day
Cause: Transition is skipped by button click during level up modal display and does not
retrigger after the modal is closed
Fix file: src/components/MahjongBoardV2.tsx
7. Voice settings preview does not stop
Symptom: When I start watching in Settings → voice settings, the audio does not
stop even when I close the settings and return to the title
Cause: When the component is unmounted, the playing audio element did not
stop
Fix file: src/components/VoiceSettings.tsx
8. All tiles are not displayed on the reconciliation screen
Symptom: All tiles at the time of reconciliation are not displayed and cannot be seen
even if you scroll
Cause: .winning-hand-tiles are set to flex-wrap: nowrap and protrude
when there are many tiles
Correction file: src/components/ResultScreen.css
2026/01/11 Updated v1.3
Bug fixesOthers# v1.3 Fixes
Bug Fixes
### 1. Dora notation does not match the actual Dora
– **Problem**: There were cases where the Dora display tiles and the actual Dora tiles did not match
– **Fix**: Modified the Dora display logic and improved
it to display the correct Dora tiles
### 2. The position of the tiles is misaligned when the tiles are drawn
– **Problem**: The position of the tiles in the hand is displayed misaligned when the tiles are drawn
– **Fix**: Eliminate
the misalignment by adjusting the CSS of the hand layout
### 3. Tiles are not visible in the character image when dark slot
– **Issue**: When declaring a dark slot, the heroine image (z-index: 5) is displayed in front of the hand display area (z-index: 1), and the tile is not visible
– **Fix**: Changed the z-index of ‘.game-play-zone’ to 1 → 10 so that it is displayed in front of the heroine image
– **Target file**: ‘src/components/MahjongBoard_v2.css’
### 4. I can’t see my role when I win
– **Problem**: If I meet the victory conditions (e.g. opponent’s jump), I will automatically switch to the VN gacha screen after 3 seconds, and I didn’t have time to check my role and score on the results screen
– **Fix**:
– Removed automatic transition (3 second timer)
– Click the “Next Station” button Maintains the results screen
until the user has fully reviewed the results before proceeding
– **Target file**: ‘src/components/MahjongBoardV2.tsx’
## What’s New

A clenched controller.
Cute friends I met on my adventure.
Monk. Wizard. Martial artist. Dancer. Princess. It was cute, wasn’t it?
On the other side of the pixel art, there was indeed a “girl”.
The gentle smile of the monk who recovers.
The magical eyes of a wizard casting spells.
The sweaty skin of a martial artist wielding his fists.
**”I want to see more of these children”**
Have you ever thought
so?
This game is a full-fledged undressing mahjong game set in an adventure RPG-style worldview.
If you win, the exclusive scene will be released. You can enjoy different situation play for each character. Equipped with the main character’s level-up elements.
The more you play, the more advantageous mahjong will be, and the more characters you will be able to attack.

## Stage setting: “A room where you can’t leave without sex”
The core situation of
this work is **”A room where you can’t leave without sex”**.
The protagonist has the ability to deploy a special barrier.
Within this barrier, the rule that the winner of mahjong can like the loser** is absolute.
The only way to escape from the barrier is to comply with the requirements of the winner.
**
“A promise is a promise……”
they say in a
trembling voice, and they take off their clothes.
There is no veto. Since you lost in mahjong, you have no choice but to obey.
This “inescapable” situation increases the excitement of this game many times over.
