Murdoku

Murdoku turns Sudoku-style deduction into a series of crime-case investigations. Each puzzle presents clues alongside a visual map containing rooms, objects, and suspects, asking you to determine where every suspect belongs. Solving a case means analyzing spatial relationships, connecting chained clues, and eliminating possibilities until only the exact arrangement remains.

A step-by-step tutorial introduces the rules before you take on additional cases, including a New York-themed investigation. Progress and scoring track your results as you work through the available puzzles. The presentation uses a police case-file style, giving the logic challenges an investigative setting without changing their focus on careful reasoning. Cases are available for free, while additional content can be unlocked as you continue.
