An unsolved case needs your deduction — read the clues, name the culprit.
Chat of Deduction is a turn-based detective mystery where reasoning corners the culprit: a contradiction in a confident answer, an alibi that quietly moved by an hour, a clue that reads differently the second time. Interrogation is free-form, without dialogue options — a case opens on deduction, not on a question. ◆ AN UNSOLVED CASE NEEDS YOUR DEDUCTION The investigation can go no further, so the file lands on the consulting detective's desk — yours. The culprit is well hidden, the alibis interlock, the decisive evidence lies concealed. Peeling that lie apart is your work. Nobody has solved this case before you; no walkthrough exists. ◆ NO FIXED ROUTE Alibis first, or relationships? Your way of thinking becomes your play style. Loose reasoning wanders, sharp thinking unsettles a suspect, and a dodge is itself a clue. ◆ THREE WAYS TO PLAY 1. Case Files — the classic mystery Cold cases entrusted to you. Search, cross-check, then name the culprit and the proof. A guess closes nothing. 2. Phantom Thief — unmask the disguise A sealed calling card announces the theft and starts the clock. Read its hints and the paper's, predict his next move, pick him out of the crowd. 3. Crime Advisor — hunt the designer of crimes He plans other people's crimes, so one case is never enough. Link clues across several, then spring the capture — startle him and he vanishes. The lure to a meeting is the endgame. ◆ FIVE WAYS A CASE FINDS YOU • Live dispatch off the police radio • A note left in the reception room • An ICPO request over a secure line • The Cold Case File Room, your pick • The newspaper — yesterday's article, today's case ◆ EVERY TURN COUNTS Questions and searches spend turns, so the order you choose is strategy. Cases run in parallel, and every file, solved or failed, stays in your archive. ◆ EVIDENCE IS READ, NOT COLLECTED A word let slip gives you a safe code; a small habit opens a locked device. The overview, clues and transcripts stay open to re-read. ◆ ABILITIES & MIND SHARDS Instant Scan reads the clues in front of you and flags what you missed. Perfect Memory searches the case for one opening: a code, a place, a record. Mind Shards, the core resource, buy extra turns, a new case or an ability — and reveal the truth behind a failure, reopen a finished case, or change your detective name. ◆ A NEWSPAPER, EVERY DAY Crime, sightings, gossip — and your solved cases in print, under your name, with how the investigation went. Archived by date. ◆ ROOKIE TO LEGENDARY DETECTIVE Reputation climbs ten ranks: Rookie, Gumshoe, Private Eye, Seasoned, Renowned, First-Rate, Ace, Elite, Master and Legendary Detective. Daily play builds a streak; reviewing a loss makes you sharper. ◆ PLAY TIPS • Turns are limited — choose what matters • Cross-check alibis against motives • Stuck? A Mind Shard beats a wasted turn ◆ MADE FOR • Detective and mystery fans between puzzles • Anyone who wants to reach the verdict themselves • Escape room, brain game and text adventure fans • Sherlocks at heart who live for the reveal • Story sessions that fit a commute ◆ FAQ Q. Too hard without a walkthrough? A. The clues play fair — everything you need is placed where you can find it — and abilities open a way. Q. Can I play in English? A. Yes — the whole game is in English. Q. Is a failed case the end? A. No. Reveal the truth or reopen the investigation. Failure builds a detective too. ◆ GOOD TO KNOW • Internet connection required • Play as a guest; Google or Apple sign-in saves records • 15 languages • Updated regularly A perfect crime stopped one investigation cold, and only your deduction is left. A client's note waits in the reception room — open your first case file in Chat of Deduction.
