About
One crime. One map. Pure logic.
Cluedoku blends the spatial puzzle mechanics of Sudoku with classic murder mystery deduction. Study the crime scene, cross-reference alibis, and catch the killer before they get away.
HOW IT WORKS:
Study the blueprint: Each level is a unique map layout—from mansions and ships to train cars and studios—filled with obstacles and open spaces.
Use Sudoku logic: Exactly one suspect per row and column. Once you place someone, cross off their lines.
Follow the clues: Read witness statements and cross-reference positions to narrow down the grid.
Expose the killer: Use deduction and elimination to correctly position every suspect and reveal the culprit.
