STATUS: UNSOLVED

Five files have landed on your desk.

Witness statements don't quite line up. A coded message was never properly interpreted. One suspect's timeline has a hole in it.

Read the narrative. Study the evidence. Solve the puzzles. Then make your final deduction before checking the solution.

Five cases. Different evidence in every file.

Substitution Cipher

Decode a message and determine what it changes about the case.

Logic Grid

Eliminate possibilities by comparing multiple facts and statements.

Timeline & Alibi

Reconstruct the sequence and find the part that doesn't fit.

Map & Location

Use spatial information to test what witnesses and suspects claim.

Code Breaking

Crack the pattern and use the result as evidence.

Final Deduction

Combine the clues and commit to your theory before reading the solution.

Build the case, not just the puzzle.

Every case includes a narrative, an evidence board with multiple clues, a final deduction question, and a complete solution explaining the reasoning.

A bonus Detective's Notebook page gives you space to track suspects, times, locations, contradictions, decoded messages, and your working theory.

True-crime atmosphere. Fictional investigations.

Every person, place, event, crime, suspect, victim, and piece of evidence in Cold Case Puzzle Files is fictional and created for entertainment. No real cold cases are used.

The files are open again.
