THE COLLECTION · INTERACTIVE CASE FILES
You’ve followed the clues. Now it’s your case to solve.
If you’ve ever wanted to examine evidence instead of being told the ending, an interactive detective mystery puts the decisions in your hands.
Cold Case Inc offers fictional browser-based investigations. Compare witness accounts, work through digital evidence and submit the conclusion you think the record supports. These are entertainment experiences—not real criminal cases.

The case is fictional. The thinking is yours.
A good mystery isn’t just a surprise ending. It’s the moment when you notice two accounts don’t fit, and the way you decide what that means.
01 / EXAMINE
Read what survives
Work through a fictional police computer holding case files, witness statements and other clues. You decide what deserves a second look.
02 / CONNECT
Test a theory
Compare details, revisit interviews and ask whether the story still holds together. You can investigate alone or discuss it with someone else.
03 / CONCLUDE
Make the call
Submit a conclusion, then discover whether the available evidence supports the theory you built.
START WITH NO PURCHASE
Try the format before buying a longer case.
Cold Case Inc offers a free short case called Flat 33, listed as an approximately 10–12-minute browser investigation. A private email sign-in link is needed to save your progress; the vendor says its newsletter signup is optional. There’s no payment required for the free case.
Best for: fans of detective fiction, puzzle games and collecting clues. Not for: anyone seeking genuine police files, a real cold-case investigation, or a guarantee that they will solve every case.
Paid cases vary in difficulty, duration and price. Check the particular case page and its current terms before purchasing.
SPONSORED GAME / HARD DIFFICULTY
When you’re ready for a larger investigation.
The publisher’s supplied banner features The Waters Edge, a hard-difficulty fictional case. Compare its current playing time, format, price and content note with other cases before choosing. A free starter case is a separate product and is not what this banner sells.
