### 1/5 — 유저도 별로없고

*2026-10-06*

게임성도 별로 고작 마작에 렉은 왜걸리는지ㅋㅋ패보보다가 매칭잡히면 그대로 겜 멈춤ㅋ

### 1/5 — Even playing with bot, still not willing to give the player a ron with just riichi

*2026-09-18*

The title tell the story, what a stupid game

We also welcome you to join our official Discord group: https://discord.gg/5z3Nw2rPNx. We will work hard to bring better content and experience to all captains, hope you can continuously follow us.

### 5/5 — 유미터진게임

*2026-09-18*

패산주작 100퍼임 병신겜

### 2/5 — Useless "SFW" filter, constant "gooner" bait

*2026-09-12*

Had written a long review but lost my progress on it :(
in short: people spending money seem to prefer sexualized content, large portion of players seem to dislike and wish for a better SFW filter at the very least but after lots of begging all we got was a corner badge and ability to retain our outfit. The filter does not actually block NSFW outfits on event screens and many basic character outfits are quite lewd, even those that appear quite childlike. The basic game features are great but they keep ignoring popular opinion. Also there was drama about an event using AI art and them denying it.

**Developer response:** Dear Captain, sorry for the bad experience. If Captain has any suggestions for improving Riichi City, please feel free to contact us anytime through the customer service email: riichicitysupport@mahjong-jp.com.We will work hard to bring better content and experience to all captains, hope you can continuously follow us.

### 3/5 — I accidentally became no.1...i have never played mahjong.

*2026-08-12*

I only played it cause the Danganronpa collab..... I thought it was like Zenless Zone Zero.... I THOUGHT IT HAD DRV3 (SAIMATSU the best) CHARACTERS BROOOOO.....

### 1/5 — AI / Generative Art

*2026-08-06*

I wanted to like this game as I like other Mahjong apps but the new "Floral Elegy" event is riddled with generative ai art. The backgrounds were the most obvious but when I started looking closer at the characters, I could see evidence of its use there too.

### 1/5 — 恶调恶心人

*2026-08-06, version 2.2.9*

完全同意评论区说的恶调，上了银河之后匹配到的几乎全是一发或者几巡内立直自摸的人。我在雀魂里稳坐雀豪的人，在这游戏上银河之前一位率还在45%，一上银河屡屡匹到这种0防守但是把把立直自摸的玩家。就光是防守水平能感觉到不是老牌友，但是能够把把自摸或者短短几巡内听大牌真的无法理解，而我的牌几乎一直不进张听不了牌，玩了20场没上过1位。领完月卡奖励就果断卸载了拜拜了您内。
哦顺便角色动画非常软sq您咋不直接卖p呢

### 2/5 — 돈쓴거개후회되는게임

*2026-07-29*

살면서 이딴 패보 처음 봄 저혈압 치료하고싶으신분들 추천합니다 몇십만원 쓴거 개후회됨 접고싶음

**Developer response:** 안녕하세요, 캡틴님. 먼저 게임 이용 중 불편을 겪으셔서 진심으로 사과드립니다. 저희 게임은 공정한 시스템을 위해 최선을 다하고 있으며, 특정 유저를 대상으로 한 조작 혹은 차별은 절대 허용하지 않습니다. 다만, 확률적 요소로 인해 주관적으로 느끼실 수 있는 부분이 있을 수 있는 점 양해 부탁드립니다. 불편을 드린점 다시 한번 사과드리며 투명한 운영을 위해 노력하겠습니다

### 1/5 — 마작하려면 다른겜가셈ㅇㅇ

*2026-07-11*

나도 떠난다

**Developer response:** 안녕하세요, 캡틴님!

소중한 건의사항을 보내 주셔서 진심으로 감사드립니다.
캡틴님의 의견은 담당 부서로 전달되어, 다른 캡틴님들께서 보내주신 다양한 목소리와 함께 깊이 있게 검토될 예정입니다.
더 나은 서비스를 제공하기 위해 귀중한 자료로 참고하겠습니다.

항상 마작 일번가를 애정 어린 관심으로 지켜봐 주시고 응원해 주셔서 감사합니다.

### 1/5 — キャラは可愛いが(2026/07/01編集)

*2026-07-01*

・エロを通り越した、ただの下品な課金衣装
・もはやセット卓レベルの過疎
・コンビ打ち,煽りなど、マナーの悪い打ち手多数
・通報が形骸化
・ブロックは一度フレンドにならない限り不可
・露骨な勝ち席負け席
・の癖に辟易して対戦放棄したプレイヤーにはペナルティ付与

この辺が特に終わってる感じです。
新星卓は一見するとそこまで過疎が進んでいない様に見受けられますが、その実botが蔓延り数を誤魔化しているだけなので、実際の同接数ではないものと思います。
炎陽,銀河卓は最早同じ人間しかいません。

ガチャはある程度継続してプレイをしているユーザーであれば、無課金でも週に2~3回程度は引けます。
キャラ排出率は5%だったかな。
ですので、体感ですが限定キャラなどが極端に手に入り難いという印象はあまり無いです。

育成要素に関してですが、このアプリはエロ,セクシー系で売ってるので、キャラの設定関係無しに育てると100%脱ぎます。ここが一番キツくて、男の自分からしても相当気持ち悪いです。
やれ裸エプロンだブラジャー摘んで手ブラだの…。
ただただ下品なエロなので中学生でもない限り喜ばないと思います。出先などではまずプレイ出来ない。

セーフモード(和了演出等を全てデフォルト表示)という機能もありますが、限定キャラの下らないカットイン等は防げません。
嫌いな方が多いであろう、2つの国のプレイヤーと当たると、【得点状況に関わらず面前大明槓+モロ乗り+頭の悪い混一色+無駄に長い限定キャラの和了演出】
この最強コンボで鬼のようにストレスが溜まります。
セーフモードを有効にした場合は、ショボい和了ムービーも消してくれないですかね。
満貫以上和了した時の普通のカットインにしてくれ。

褒められる点は
・デフォルトで役の読み上げがある
・初心者の方でもルールが覚えやすいように、Duolingoのような機能がある
・娯楽戦が豊富
程度でしょうか…。

正直この3点は優秀だと思いますが、前述したマイナスポイントを相殺できるものではありませんので、☆1とさせていただきます。
雀魂から移行してきたこともあり、初めの内は役の読み上げもあるしで楽しかったです。

ですが、やればやる程“過疎”と“エロ寄せの気持ち悪い和了演出”がジワジワと効いてきて、嫌いになっていきます。
オススメはしません。

**Developer response:** 親愛なるキャプテン様、

ご不快な思いをさせてしまい申し訳ございません。
ゲーム内はSHA-256牌山検証機能が実装され、公式サイトにも生成方法を公開しております。SHA256は公用の標準的なアルゴリズムで、暗号化や復号化に広く用いられています。一定のアルゴリズムを通してデータ（牌山の牌順）をハッシュ値に変換します。対局が始まった時に局毎にドラ表示牌のとこをタップするとSHA256コードが出ます。したがって、対局前に牌山が確定しており、牌を次々生成することは不可能です。鳴きの発生によるツモ牌のズレも考えると、特定のプレイヤーを勝たせる牌山の生成はできません。
ですので、弊社から配牌を操作することが一切ございませんと保証します。
何卒ご了承くださいますようお願い申し上げます。
