About Clue.doku
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. WHY YOU'LL LOVE IT: Handcrafted cases & diverse settings: Unique murder mysteries in distinct locations, from quick coffee-break puzzles to brain-melting cases. Detective aesthetic: Blueprint-style grids and hand-drawn crime scene assets. No sign-up required: Jump straight into the investigation anonymously. Clean elimination grid: Easily visualize blocked rows and columns to solve puzzles step-by-step. Grab your magnifying glass, study the floor plan, and put your logic to the test. Can you solve every case? Download Cluedoku and start investigating today!
