Description

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.
