Detecsudoku
A detective puzzle table where every student appears once, objects stay fixed, and every clue narrows the case until one final answer remains.
Promise
Place the faces. Read the scene. Crack the case.
Place characters
Select a character, then tap a scene cell. Moving a character keeps them unique.
Read the scene
Objects, areas and character positions are the puzzle. Just place portraits and check clues.
Read clues
Clues are visual restrictions: row, column, area, adjacency and direction.
Check progress
The engine marks clues as unknown, satisfied or violated before the final answer.
Today's case

Festival posters point to the wrong door. A bell schedule, a hallway note and the scene layout identify who switched them.
Tutorial: The Locker Code
A folded note appears beside Locker 27. Four students were nearby, and the scene itself gives away who left it.
Playable school mysteries
The Locker Code
A note appears near the lockers before first period. The hallway layout points to the student who left it.
The Library Map
An old campus map is found open on the library table. Someone circled a route and vanished before the librarian returned.
The Lab Key
A copper key appears beside the experiment tray. The scene around it shows who placed it there.
Built beside Today's Sudoku, but not a reskin
Detecsudoku keeps the sudoku feeling of exact placement, but the board is a visual investigation scene. If you want classic sudoku practice, the daily boards are still one click away.
