How it works

A deduction game built from evidence, not guesses.

01

Read every statement

Every sentence maps to an executable rule about a room, object, row, column, or another person.

02

Reconstruct the room

Drag portraits onto open floor, record candidates, and rule out impossible positions without losing your reasoning.

03

Reveal the murderer

Complete the only layout that satisfies every statement, and the victim’s sole companion is revealed as the murderer.

Open field files

Each case stands on its own evidence.

Begin with a compact reconstruction or move directly to a larger, more demanding scene.
