Solving cases in CaseCracker 3 can become incredibly confusing once the investigation board starts filling up with clues, passwords, timestamps, witness statements, and evidence chains. Unlike most detective games, CaseCracker 3 expects players to manually connect nearly everything themselves, which is why many investigations suddenly feel overwhelming halfway through.
Some clues only unlock after combining other evidence first. Others require specific passwords, timestamps, or hidden connections between multiple suspects. On top of that, several late-game investigations intentionally throw misleading evidence at you to make deductions harder.
This guide explains every major case step-by-step, including clue chains, passwords, important deductions, and final report answers so you can progress without getting completely stuck.
CaseCracker 3 Walkthrough Guide – All Case Endings
Case 1 introduces the game’s investigation system and clue-linking mechanics. At first it looks like a simple murder involving Liu Feng, but the deeper you investigate, the more complicated the setup becomes.
The biggest challenge in this case is understanding how evidence chains unlock newer investigations.
Important Early Clues
Start by investigating:
- Liu Feng
- Billboard
- Bloodstains
- Huangquanpo
- Funeral Home
These clues unlock most of the investigation paths needed later.
Key Investigation Chains
Billboard Investigation
The billboard clue eventually connects to:
- Hongdou Mobile Phone

This helps establish the victim’s movement and communication trail.
Autopsy Report Chain
The autopsy report becomes one of the most important clues in the entire case because it unlocks:
- U-shaped Magnet
- Headscarves

This is where the case starts shifting away from a normal murder investigation into staged body transportation.
Xinglong Gas Station
Investigating the gas station is extremely important because it connects:
- Liu Feng

This clue becomes critical later when identifying the perpetrator’s actual location.

CaseCracker 3 becomes increasingly complex with every chapter, especially once cases begin overlapping with older crimes, hidden organizations, and recurring suspects.
The game rewards patience more than speed. The more carefully you follow evidence chains and timelines, the easier the later cases become to understand.
