// HOW IT WORKS

Five Stages. One Killer.

Each case unfolds across five stages. New evidence, new contradictions, and one explosive twist — before you submit your final theory.

Crime Discovered

The case file opens. You receive the crime description, initial suspects, and the first pieces of evidence left at the scene.

New Evidence

Phone records, CCTV footage, financial logs, and witness statements surface. Study each piece — contradictions are hiding in plain sight.

Interrogations

All suspects are brought in for questioning. Read their answers carefully — someone is lying, and the right question will expose them.

Major Twist

An unexpected revelation changes everything. The direction of the investigation shifts — and everything you thought you knew is now in question.

Final Theory

Submit your complete theory — culprit, method, motive, and the evidence that clinches it. Your score is calculated instantly.

Picking the most decisive evidence earns you more points. Selecting phone records when CCTV was clearer? That costs you precision marks.

INTERROGATION INSIGHT
