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.
