How to play
Study the floor plan
Each case is a map with rooms and furniture. Exactly one person per row, at most one per column.
Read the clues
“Irene was in the greenhouse”, “Ramón was sitting next to a plant”, “Nora was just north of the fridge”…
Place the suspects
Place each suspect, cross out tiles and take notes. Every case has a single solution: no guessing, just deduction.
Accuse the murderer
The killer is the only suspect who was in the same room as the victim. When you’re sure, accuse!
02 · Suspects
The usual suspects
Every case has its cast. Tap a card to read their file… and remember: only one is the killer.
