How it works
A deduction game built from evidence, not guesses.
Reconstruct the room
Drag portraits onto open floor, record candidates, and rule out impossible positions without losing your reasoning.
Prove the murderer
Complete the only layout that satisfies every statement, then identify the victim’s sole companion.
Open field files
Each case stands on its own evidence.
Begin with a compact reconstruction or move directly to a larger, more demanding scene.
