The investigative method
Reason from evidence, not guesses.
Every case is a closed logic system. The clues tell you how people, objects, places, and motives relate. Your job is to make every fact agree.
Build the relationships
Match each suspect with one tool, one location, and one motive in the deduction matrix.
One-to-one logicDeliver the verdict
Submit the complete accusation only after the evidence leaves no contradiction behind.
One solution
Connect every clue
Four categories. Twenty relationships. One coherent case.
Each suspect belongs with exactly one tool, location, and motive. Confirm what the evidence proves, reject what it rules out, and let every deduction narrow the field.
- Five suspects, five tools, five locations, and five motives
- Clear positive and negative relationship marks
- Focused solve time pauses when you leave the case
- Optional hints when you decide you want help
Eliminate the impossible
Turn contradictions into certainty.
A good deduction does more than fill one square. It changes what can be true everywhere else. Keep the whole matrix consistent until every row is resolved.
