GridNoir turns murder sudoku into a large, living logic puzzle collection.
Play 1500+ cases across themed casebooks, from classic crime scenes to cruise ships, hotels, campuses, trains, museums and more. Open a daily challenge, read the suspect cards, inspect the rooms and place each person on the grid.
Each suspect belongs in one row and one column. Every clue narrows the possibilities until the victim, the culprit and the crime scene finally make sense.
No guessing. No account. Just deduction.
