Getting through CaseCracker 3 is less about solving one mystery at a time and more about surviving an avalanche of interconnected evidence. Every case introduces new suspects, hidden timelines, digital records, passwords, witness contradictions, and old crimes that slowly connect into a much larger conspiracy.
The hardest part about the game is that it rarely tells you what clue actually matters. A random receipt, surveillance camera, or medical record that looks unimportant early on can completely expose the killer hours later.
CaseCracker 3 Guide Wiki – Walkthrough, Investigation
Most players struggle because they investigate clues in the wrong order.
CaseCracker 3 uses layered clue progression:
- Primary evidence
- Linked investigation
- Witness statement
- Motive discovery
- Timeline contradiction
- Final deduction
Sometimes a clue looks completely useless until another investigation unlocks additional context later.
If progress slows down:
- Recheck witness statements
- Compare dates carefully
- Revisit older locations
- Investigate newly unlocked objects immediately
- Look for repeated names across multiple cases
The game constantly reuses organizations, locations, and suspects.
Case 1 Walkthrough (CC250712)
What the First Case Is Really About
The first investigation initially looks simple:
- A body
- Blood evidence
- A billboard crime scene
But the case slowly reveals:
- Evidence staging
- Body transportation
- Signal interference
- Fake timelines
This chapter mainly teaches players how clue chains function.
Best Early Investigation Order
To avoid getting stuck early, investigate:
- Liu Feng
- Billboard
- Bloodstains
- Huangquanpo
- Funeral Home
These clues unlock most major branches quickly.
Why the Billboard Is Important
The billboard clue unlocks:
- Hongdou Mobile Phone
- Public Telephone Booth
- Huangquanpo connection
This establishes the victim’s movement timeline and communication history.
The Autopsy Report Is the Biggest Clue
The autopsy report becomes the turning point of the case because it unlocks:
- U-shaped Magnet
- Headscarves
- Yuan Feiyu
This evidence reveals that:
- The body was moved
- The crime scene was manipulated
- Magnetism played a role in transportation
The case stops being a normal murder investigation after this discovery.
Xinglong Gas Station Investigation
This location becomes extremely important because it connects:
- Wang Wei
- Liu Feng
- Timeline inconsistencies
- Financial activity
It eventually exposes the killer’s true location during the crime.
Important Passwords
| Clue | Password |
|---|---|
| U-Shaped Magnet | DT362880 |
What Actually Happened
The victim was killed with a crowbar before the body was relocated and staged near the billboard.
Signal jamming was used to disrupt communication records and confuse the investigation timeline.
Several pieces of evidence around the billboard were intentionally planted to mislead investigators.

Why Case 2 Becomes Much Harder

- Snake venom
- Medical evidence
- Biological toxins
- Multiple overlapping suspects
This chapter depends heavily on movement tracking and timeline analysis.
Best Clues to Investigate First
Start with:
- Zhang Weicheng

The Real Core of the Case
The game intentionally floods the player with misleading medical evidence.
At first it feels like:
- Drug overdose
- Medical malpractice
- Random poisoning
But the real investigation revolves around:
- Venom handling
- Deliberate poisoning
- Biological toxin distribution
- Evidence manipulation
Why Crimson Serpent Matters
Crimson Serpent becomes one of the most important clues because it identifies:
- The poison source
- Delivery method
- Which suspects had access
Without understanding this clue chain, the case feels almost impossible to follow.
Why the Office Is the Real Crime Scene
The office repeatedly appears throughout the investigation because it connects:
- Poison mixing
- Powder disposal
- Medication handling
- Witness overlap
Most major evidence eventually points back there.
Experimental Records and Sticky Notes
This clue combination exposes:
- The toxin preparation process
- Who disposed of the powder
- The biological research connection
It becomes one of the final pieces needed to identify the killer.

CaseCracker 3 becomes far more rewarding once you stop treating it like a simple clue-matching game and start approaching it like a timeline investigation simulator.
Most mysteries are not solved through one single clue. They are solved by slowly connecting movement patterns, hidden motives, surveillance evidence, old crimes, and contradictions across multiple investigations.
