Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 1.43/day in the week to Aug 10 → 3.71/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
A voice is saying your name. A WWII-era machine, long hidden in a church basement, whirs to life. Through a crackling speaker, a man asks you to find a stolen book. He only knows the title. Time is running out.
The machine, created by Bletchley Park engineers Cecil Caulderly and Beatrice Dooler, contains a vast archive of obscure books, letters, and journals fed in over the span of fifty years in an attempt to crack the code of reality. As their lives fell apart, the machine kept working.
Navigate the computer’s archive. Link its obscure texts and uncover its creators’ secrets. Communicate with the man behind the speaker to figure out your role in this mystery. Destroy the book at the core of the machine — before it’s too late.
Deduce links through the archive to locate hidden sources.
Unravel the stories and unearth the secrets of the books’ authors and the machine's creators.
Map the archive and find the book that will rewrite the world.
Talk with your handler at any time, creating a dynamic audio drama that responds as you explore.
Featuring the voices of Rebekah McLoughlin (The SCP Archives, Eternal Threads), Paul Warren (A Highland Song, Viewfinder, The Séance of Blake Manor) and Phillipe Bosher (Baldur's Gate 3, Doctor Who, The Hitchhiker’s Guide to the Galaxy).
Original soundtrack by Laurence Chapman (A Highland Song, Heaven's Vault, The Mask of the Rose).
TR-49 takes inspiration from narrative deduction games like The Roottrees are Dead, The Return of the Obra Dinn, Type Help and Her Story, and from audio dramas like The Magnus Archives and ars PARADOXICA.
Written and created by the award-winning team behind Heaven's Vault, Overboard!, and A Highland Song.

An enjoyable experience, intruigue, logic, puzzling, well written, well acted, and a satisfying experience. Short but well worth the experience.
Another excellent Inkle game. I don't think I found all the secrets, but I still had a great time with the system.
A short, clever puzzle game that mixes worldbuilding, discovery, mystery, and adventure all in on.

Fun detective like puzzle game
One of my favorite games in a while. Really like the main puzzle mechanic, creepy vibes, and unfolding storyline. Incredibly impressed by how interesting a lot of the deductions involved were, and how completely the game let me loose with little guard rails. Highly recommend!
An incomprehensible, unplayable mess. Essentially a walking simulator where you click instead of walk? Maybe there's more to it, but there's not even an effort to make you want it, or any edges to grab onto. Click click click "something happened!" *random "story" exposition that is meaningless, click click click repeat repeat." Voice acting is OK but the writing is absolute trash and gameplay seems nonexistent. I really wish Steam would start banning publishers / developers who blatantly lie about their game content. Pass on this. To be very clear: this "puzzle game" has ABSOLUTELY NO PUZZLE ELEMENTS.
Really good deduction game with great writing as usual from inkle. I might be too stupid to figure it all out but what I did find was excellent!
Great writing, compelling plot and tickles that mystery solving itch. This game is so unique and underrated. I went in without any expectations and went through a journey from utter confusion, then vague comprehension, then super invested and feeling like I've known all the characters for years. I think the last time I had this type of comprehension rollercoaster was Return of the Obra Dinn. If you liked this and haven't played any other Inkle games, their whole backlog is delightful. My favorite is Heaven's Vault.
Fun puzzle game, with an interesting concept and novel interactions. Very retro feel throughout. The only real issue I can into was that with it being an "open" world, I accidentally found the final piece when I was half way through the game, which immediately shifted the tone of the narrations in a way that didn't make any sense yet. Got there eventually.
Absolutely stunning. One of the best games I've played recently; the story genuinely nearly made me shed a few tears. Still terribly upset there's no 'Abbi meets Liam IRL' ending, but okay.. Beautiful voice acting anyways, and I was really surprised that trying to exhaust the dialogue had consequences. Overall will 100% recommend.
