The Method

How to Crack a Case

Every case has one truth buried in the evidence. Someone is lying — and they always leave a trail.

01
📋
Read the Brief
Get the facts. Three suspects, one incident, and a folder of evidence. Someone's story doesn't hold up.
02
🔍
Study the Evidence
Chat logs. Receipts. Police notes. Social posts. Swipe to mark anything suspicious with a Doubt point, or pinch to zoom in on the fine print. Take notes in your detective's notebook as you go.
03
🔗
Find the Contradiction
Two pieces of evidence can't both be true. Identify the pair. That's the crack in the case.
04
👤
Name the Liar
Submit your theory. Tag the key evidence. Pick your culprit. Then see if you were right.
