## What is Jack & Detectives?

Jack the Ripper is hiding among us. Can you find him?

In this turn-based detection game, two teams face off against each other: Jack the Ripper and the detectives.
Jack has to get away with murder without being found out by the detectives, who in turn need to find out who he is.
Unlike other detection games, you can't talk with the other players in Jack & Detectives, and you must figure out the truth based only on their actions.
Players cannot get eliminated, so everyone gets to enjoy the game to its end. Furthermore, since a game only last ten minutes, you don't need to commit a lot of time just to play.

■ Jack: Commit murders without being found out.
A serial killer lurking in the shadows. In order to win, he must make sure he isn't chosen during the voting phase.

■ Detectives: Find Jack, who is hidden among us.
Private detectives hired by the London police. In order to win, they must correctly vote Jack out during the voting phase.

■ Jack maniac: Muddy the waters so that Jack isn't found.
A maniac whose allegiance lies with Jack the Ripper. He wins if Jack wins, even if he gets voted out himself.


The detectives must plan their moves to corner the suspect among them!

At the start of each game, players are assigned a role at random.
Then, everyone places their token on a London tile of their choosing.


Jack must trick them and frame one of them!

Once they have done so, night will fall, and Jack the Ripper will commit his first murder. (In certain cases, there will be no murder during the first night)

Vote to choose whom to arrest!

The detectives located near the crime scene will become suspects. Who's on justice's side? Who's the murderer among us?
After the second murder, the voting phase starts. Everyone has to vote for the person that they think is secretly Jack the Ripper.
This is where the real battle of wits between the detectives and Jack starts.

### 2/5 — AIありえない…

*2025-12-26, version 0.2.3*

ジャックを囲い、何度か犯行不可能にし、どう考えてもそのキャラクターしか疑えない時、仮投票の時は全員そこに投票したのに本投票でAIが皆犯行不可能な人物に投票して敗北…。

### 1/5 — 対戦相手がずっとAI😭

*2025-10-02, version 0.2.3*

人狼好きだけど口下手な私向きと思って、広告削除に課金してまで楽しんでました。
でも毎回不自然な投票結果になるので、違和感を感じてレビューを見に来たら
過疎でAIとマッチングしてたんですね…😭
急につまらなくなってしまいました👍

### 2/5 — ゲーム性は面白い

*2025-06-25*

チャット無し／ジャックが2キルしたら終わりなのは面白いと思いますがその分ジャックが圧倒的に不利になったり逆に3択の運ゲーになったり人狼ゲームの醍醐味である考察要素は大分薄れてるように思います。

リリース当初はプレイヤーもそれなりにいてスタンプでコミュニケーションをとったり出来たのですが最近はAIとしかマッチしない上、AIのプレイがゴミで特に市民側のAIは犯罪可能位置を潰さず意味不明なところに移動したり、的外れの投票をしたり最悪です。

ゲーム性は惜しいところはありつつも面白いが故に人がおらず退屈なAI戦しか出来ないのは悲しいです。

### 4/5 — 対戦相手はAI？

*2025-06-24*

ゲーム性はとても面白いです！
暇な時にサクッと遊べて、長時間はやらないけど毎日やるくらいにはハマってます。

ただし明らかにAIと対戦させられているような。
仮投票で全票入ったと思ったら、本投票では別のところに全票入ったり…

AIだとしても駒の挙動は精度高いので気になりませんが、やはり「読み合い」みたいなことは出来ないのかなと。

### 1/5 — COMがあまりにもお粗末

*2025-06-18*

探偵・ジャック、どちらの陣営でもNPCのAIがあまりにも意味不明・とんちんかんな事をし始める為、ゲームとして成り立たない。

過疎りすぎてて、あまりに人とマッチングしない為
NPCとやるハメになり、詰めることもできず運ゲーをする事になります。

### 3/5 — トラブル無いから楽しい

*2025-05-19*

チャットやボイチャが無いのでイザコザが無いのが良い
ただ、中々マッチしない事がある
そして犯人が上手いと暴く側は最終的に勘になる事もしばしば。
基本的に犯行スキップは2回。
詰むと強制的にスキップになる。
1ゲーム5分〜10分程度で終わりその後必ず広告が流れるが
広告の長さは短めなので特に苦にならない
ルールも簡単で犯行が出来るマスは自分の周りのマスのみだから
初手から問題なく遊べる
犯行が行われたマスの近くにいた人を容疑者候補として
チェックして見定めて投票するだけ

### 4/5 — 人がいない

*2025-02-18, version 0.2.3*

タイトル通りインストール
から3日経っても一向にプレイ
できた事がないので、
ソロでずっとやっているが、
思っていたのという違う

### 3/5 — 面白いゲームだが

*2025-02-15, version 0.2.3*

ゲームとしては非常に面白いが、人が少なくAIと戦うことが多い。かつAIが弱すぎる。自称潜入捜査官が4人いる際に、ジャックじゃないと判断できるプレイヤーに投票が4集まった時は目を疑った。
他のレビュワーで、最終的に2〜3択の運ゲーと言ってる人の大部分は、このゲームのことをまだよくわかってない。麻雀と似たようなもので、運ゲーという結論を言うのは大部分が素人と、ほんの僅かの玄人のみ。
最終的に2択なりになった時に、そこまでのプレイングの違和感から少しでも正解択を考えようとしてる人は少なそう。

### 4/5 — アプデ後のバグ修正依頼

*2025-02-06*

非常に面白いのでオススメですが、2/6のアップデートをきっかけに、ジャックのアクションと場所の選択が操作していないのに勝手に動いてしまうバクがあります。本日3プレイしましたが2プレイで合計3回このようなことがありました。改善してください。

### 5/5 — とても良いバランスのゲームです！

*2025-02-05, version 0.2.1*

人狼ゲームが好きならとても楽しめると思います！
駆け引きや心理戦ガンガンできます。
人間がいなくてもコンピューターが相手してくれます。それなりに楽しめます。人間とやる方が面白いので参加人数増えてほしいな。

あと、欠員をコンピューターで埋める事は悪い事では無いけど、コンピューターとわかるようにしてくれるまた推理の内容が変わってくるのでより楽しめるのでは無いかと思います。製作者の方、検討よろしくお願いします。
