--- title: 'Show HN: Uncracked City, detective game where you question LLM suspects that lie' link: https://uncracked.city/ source: hnrss-org published: 2026-11-03T21:20:03Z updated: 2026-11-03T21:20:03Z first_seen: 2026-11-04T15:43:16.719955117Z authors: - passkey1510 summary: 'To give you some context on the project. I''m a solo founder and I use AI heavily in my work. The idea came from wanting players to discover cities. Each city has its own history, so every case is set in a real city with real public places. The crime and the people are on other hand invented. The part that I care most is the playable aspect of the game, a model plays the detective and must solve the case before it goes live. As of today: it''s free on Android, the iOS version is still waiting to be reviewed by Apple. It''s available in six popular languages, but adding more languages is just a matter of time and demand.My long term vision if it takes off: weekly cases, private parties like a team-building escape game, an MCP so a game master can build their own scenario from ChatGPT or Claude, and maybe tourism offices since players travel the world.

A detective game set in real cities.

Meg Ashcombe, the last of her family, lies at the foot of her grand staircase, one slipper on the thirteenth step, the front door bolted from inside. Half the town says the Grey Captain finally took her. Four suspects. One of them lies. Nobody has solved it yet [Watch the teaser on YouTube](https://www.youtube.com/watch?v=4_y0d9R1Z0s) ## How you investigate 1. 01 ### Search the places Every case happens in a real neighbourhood. Find the clues, open what is locked. 2. 02 ### Question the suspects Ask your own questions, typed or spoken, in any of the game's six languages. Each suspect answers in their own voice. Some of them lie. 3. 03 ### Catch the lie, then report Hold a clue against a statement. When the lie cracks, write your report: three tries, not one more. ## A world tour to learn. Then the real cases. Paris, Rio de Janeiro, Marrakech, Tokyo, Sydney: five training levels, each harder than the last. Then come the real cases, harder still. Each one shows how many investigators have solved it. For most of them: nobody. Not yet. Nobody has solved it yet ## One city, one secret The first time you open a case, you fly there across the map. Solve it, and its city is stamped in your passport. - ![Venice](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-perfect-copy.webp&w=3840&q=75) Venice - ![Lisbon](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-sun-panel-of-alfama.webp&w=3840&q=75) Lisbon - ![Edinburgh](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-vanished-score.webp&w=3840&q=75) Edinburgh - ![Amsterdam](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-blue-lady-s-handle.webp&w=3840&q=75) Amsterdam - ![Cusco](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-silver-charango-2.webp&w=3840&q=75) Cusco - ![Seoul](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-jade-hairpin-2.webp&w=3840&q=75) Seoul - ![Cape Town](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-silver-fin-2.webp&w=3840&q=75) Cape Town - ![New York](https://uncracked.city/_next/image?url=%2Fcases%2Fthe-grand-central-watch.webp&w=3840&q=75) New York ## Help and contact A question, a bug, a suspect's line that goes wrong: write to us.
