About Whodunit Sudoku Demo
"Whodunit Sudoku" is a Murdoku-like game. The concept of Murdoku was created by Manuel Garand. Here, I would like to extend my sincerest gratitude and respect to the original author. This is an unofficial independent work. As a solo developer, I started from scratch and handled the art, programming, and level design all by myself. Based on the rules of the original game, I also innovated some of the detailed rules, hoping to bring you a different puzzle-solving experience.
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.
