About this game

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.

Features:
- 1500+ murder sudoku cases and daily challenges
- Themed casebooks with different locations and suspects
- Crime-scene boards with rooms, objects and clue cards
- Suspects, victims, rooms, objects and alibis
- Helpful hints, score summaries and case-closing results
- Optional rewarded ads for extra hints or early case access
- Progress saved on your device

If you search for crimoku, murdoku, murder sudoku, criminal sudoku, detective puzzles, whodunit games or logic grid puzzles, GridNoir gives you a new case to reason through, one square at a time.
