Roomdoku: Sudoku Whodunit

Place suspects. Read clues. Catch the culprit. A pocket-sized whodunit puzzle.

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.
