## What is Roomdoku?

Step into a noir whodunit and solve cases with pure logic. Roomdoku blends the satisfying deduction of sudoku with the tension of a murder mystery — place suspects onto a grid, read the clues, and rule out the impossible until only the culprit remains.

How to play
• Each case gives you a grid, a cast of suspects, and a handful of clues.
• Move suspects between rooms using what the clues tell you ("in the library", "next to the victim", "not on a wooden tile").
• When every suspect sits in the correct place, the culprit is revealed.

Features
• Four difficulty tiers: Easy, Medium, Hard, Expert.
• Themed cases with unique characters and rooms.
• Three hint types: reveal a cell, undo wrong placements, unmask the culprit.
• Daily and monthly leaderboards — race the world for the fastest solve.
• Team play: join a team and push your team's daily ranking.
• Friends: trade friend codes and compare solves.
• Daily and weekly missions with rewards.
• Streaks that grow as you play each day.

Play anywhere

• Offline-ready — progress lives on your device and syncs to the cloud.

### 5/5 — 추리라 재밌어요

### 5/5 — 시간가는줄 모르고 하는 즁..

*2026-05-12*

출퇴근 버스에서 할 만한 게임 찾고 있었는데 딱이네용 ㅎ 추리 좋아하는 사람이라면 꽤 재밌게 할 듯! 분위기가 독특하네요

### 5/5 — 시간가는줄 몰랐어요

*2026-05-05*

처음엔 그냥 스도쿠 변형 게임인가 싶었는데 완전 달라요. 단서를 읽고 용의자를 방에 배치해서 범인을 찾아내는 방식인데, 논리적으로 하나씩 좁혀가다가 딱 맞아떨어질 때의 쾌감이 진짜 장난 아닙니다. 스도쿠 특유의 논리 요소에 추리 까지 섞여서 두 배로 재미있어요. 사건마다 배경이랑 캐릭터가 달라져서 질리지 않고 난이도도 쉬움부터 엑스퍼트까지 있어서 처음엔 쉬운 것부터 감 잡고 올라가면 됩니다.
추리 소설 좋아하거나 논리 퍼즐 좋아하는 분들한테 강력 추천. 무료인데 이 퀄리티면 진짜 혜자 게임이에요!!!!!
