Roomdoku: Sudoku Whodunit

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.
