Whodunit Sudoku is a logic puzzle where each case is a grid-based crime scene. Your goal is to place every suspect and identify the killer through strict logical deduction.

Grid Placement The crime scene is divided into a grid. Place all suspects following Sudoku rules: each row and each column can contain only one suspect.

The Crime Scene Each grid contains rooms, furniture, walls, and open spaces. Rooms are bounded by walls or doorways. Only empty floor tiles are valid positions for suspects.

Clues Written clues describe spatial relationships between suspects and the environment. These include directional clues, proximity clues, relative position clues, and boundary clues. Every clue must be satisfied by the final arrangement.

Once all suspects are placed, the killer is the one left alone in the same room as the victim.
