Cold Case Bureau
90 cases. One detective.

The complete overhaul is here. A new case every day for everyone, interrogations, forensics, warrants and every verdict now tells you exactly what held and what didn't.
One case a day. The same case for everyone. Nothing to buy, no ads, no account.
Cold Case Bureau puts a case file on your desk: the victim, the suspects, the evidence, and somewhere inside it, one story that doesn't hold together. Read the file. Find the two statements that can't both be true. Pin them on the board and watch the string pull tight.
Then build your theory, not a guess from a menu, but an argument, element by element. Get part of it right and that part locks in. Get part of it wrong and the case tells you exactly which part, and lets you keep working.
THE DAILY CASE
Every day the Bureau opens one case, and it's the same case for every player in the world. Solve it, keep your streak alive, and share your result. A spoiler-free grid that shows how you did without giving anything away.
INVESTIGATE
Four Case Hours, and a case that offers more than four hours of leads. Press a suspect with a piece of evidence and what they say depends on what you chose to show them. Pull records nobody asked for. Send evidence to the lab. Earn a warrant with proof from your board. A wasted half hour is on you, but the case can always be closed from the file alone. Nothing is ever locked behind a guess.
THE INVESTIGATION BOARD
Real red string. Connect two pieces of evidence that contradict each other and the connection is established permanently. The board is where you prove people are lying.
THE ARCHIVE
More than ninety past Daily cases, free to work in any order, from quick Rookie files to five-suspect Senior investigations with paper trails that close like a net.
FAIR PLAY, GUARANTEED
Every case is verified solvable from its own evidence before it ships. Every question has exactly one answer the file supports. If you reason correctly, you win - that's the whole promise.
No ads. No purchases. No timers that want your money. Just cases.
This is a complete overhaul — the game the reviews asked for.
THE DAILY CASE — One new case a day, the same for everyone. Streaks, and a spoiler-free result you can share.
FAIR VERDICTS — The old INCORRECT is gone forever. Your theory is judged element by element: what you got right locks in, what didn't hold is named, and you keep working. You can no longer lose to a question the evidence never answered.
INVESTIGATE — Spend four Case Hours pressing suspects with evidence of your choosing, pulling records, sending items to the lab, and earning warrants with proof from your board. Every case still closes from the file alone — investigation earns you corroboration, never the answer.
THE BOARD IS REAL — Connect contradicting evidence and the red string pulls tight and locks. Proving every contradiction now earns a bonus.
CASE FILES YOU CAN SEE — Suspects have faces. Crime scenes have photographs. Phone extracts look like phone extracts, statements are signed, camera stills get the dark chrome.
FASTER PROGRESSION — Detective, Senior and Major tiers unlock at a third of the old requirements.
To the two reviewers who called the old version half-baked: you were right, this update is for you, and your cases are waiting.
