Uncracked City is presented on its website as a detective game built around exploring real-city settings, questioning suspects powered by language models and testing their statements against clues. Its site describes five training levels, a featured Salem case and a three-attempt limit for filing a report; release timing and technical details are not provided.

Uncracked City, a detective game presented in a Show HN post, asks players to search real-city settings, question suspects powered by large language models and use clues to test whether their statements are false. The game’s website describes a featured Halloween case set in Salem and says the title is coming to the App Store and available to get on Google Play, but it does not give release dates or technical details about how its suspects work.

The site describes a three-part investigation: players search locations for clues, ask suspects questions by typing or speaking, and then put evidence against a suspect’s statement. Suspects answer in individual voices, and the website says some of them lie. Players must then write a case report, with the game allowing three attempts.

The featured case, “The Thirteenth Step,” is set in Salem in 2025, the morning after Halloween. Its fictional premise is that Meg Ashcombe is found at the foot of her grand staircase, with one slipper on the thirteenth step and the front door bolted from inside. The website introduces four suspects and says one lies; it does not identify the culprit or provide a solution.

Before the main cases, the game says it offers five training levels in Paris, Rio de Janeiro, Marrakech, Tokyo and Sydney, with difficulty increasing across the sequence. The site lists further case locations including Venice, Lisbon, Edinburgh, Amsterdam, Cusco, Seoul, Cape Town and New York. It says case pages show how many investigators have solved each one, while describing most as unsolved. The game supports questions in six languages, according to its website.

How AI Shapes the Investigation

The game’s central design makes conversation part of the puzzle rather than simply a way to gather exposition. Players are expected to form their own questions, compare answers with physical clues and decide when they have enough evidence to accuse someone in a report. That approach could make each investigation feel less like following a fixed sequence of dialogue choices, though the site does not explain how much freedom players have or how responses change during play.

The premise also puts an important limit on the role of AI: a suspect’s confident answer is not necessarily reliable within the game. The intended challenge is to check statements against evidence gathered in the setting. Whether the language-model responses are generated dynamically, drawn from prepared dialogue, or produced through a combination of methods is not disclosed, so the degree of conversational variety cannot be independently assessed from the supplied materials.

Cases Across Real-World Cities

Uncracked City’s website frames its cases around real neighborhoods and cities, with players travelling between locations through an in-game map. It says a solved case stamps that city into the player’s passport. This location-based structure links the investigation format to a sequence of distinct settings rather than presenting a single continuous case.

The site describes a progression from the five training levels to more difficult “real cases.” It also presents community solve counts as part of the case listings, suggesting players can see whether others have cracked a mystery. The supplied page does not explain how those counts are collected or whether cases can receive updates after launch.

“Search the places, question the suspects, catch the lie, and write the report nobody has managed to write yet.”

Release and AI Details Remain Open

The supplied material does not give a launch date, pricing, supported devices, or a confirmed release status for either store. The website says the game is coming to the App Store and offers a Google Play link, but that alone does not establish when it will be available in each region.

It is also unclear which language models, if any, power the suspects; whether internet access is required; how responses are moderated; or how the game handles answers that do not fit a case. The site says players can flag a suspect reply that goes wrong and contact the developers, but gives no response-time commitment or explanation of how flagged replies are reviewed. No independent gameplay testing or performance information is included in the supplied source.

Watch for Store and Gameplay Updates

The next concrete milestones are store availability and further details from the developers about release timing and the game’s operation. Players interested in the title can check its App Store and Google Play listings, as well as the teaser linked from the website, for updates. The source does not announce a launch schedule, so no date can be confirmed.

After release, practical questions will include how consistently players can test suspect statements against clues, how the three-report-attempt rule works, and whether the six-language question support covers the full investigation experience. Those points remain unverified until the game is available for hands-on review.
