About
A murder has happened. Everyone is a suspect — and the board is the crime scene.
Detective Sudoku turns sudoku-style deduction into a murder mystery. Place every character on the grid so all of their statements hold true. Each row and each column holds exactly one person. When only one suspect shares a room with the victim, you have found the murderer.
HOW TO PLAY
• Read each suspect's clue — "north of the plant", "beside the bed", "alone in the kitchen". Every clue is true.
• Rooms, walls and furniture all matter. "Beside" never crosses a wall.
• Rule out squares with crosses, pencil in possibilities with notes.
• Place the last suspect and close the case.
FEATURES
• The Daily Case — one new mystery every day, the same for everyone
• Dozens of handcrafted cases in themed case folders, from easy to hard
• Score and star ratings on every solved case
• Hints that nudge your reasoning, and reveals for when you are truly stuck — your supply refills every day you open the app
• Automatic save — leave anytime, resume exactly where you were
• Fully offline — solve cases anywhere, no internet needed
• Available in 23 languages
No numbers, no guessing — just pure deduction. Can you close every case?
