GAMESLASHCaseZero opens a Jac-built detective game with four rule-based advisor roles
By GameSlash
CaseZero's October 18 project update details evidence-based interrogations and four advisor roles, while confirming that optional Gemini dialogue remains unimplemented.
CaseZero is a browser detective game made in Jac for a 2026 AI Hackathon associated with Jaseci Labs and the University of Moratuwa. Its public project was updated on October 18 and describes a playable mystery, The Missing Prototype, where investigators collect records, question suspects and make evidence-backed accusations.
Four advisor roles, but no live Gemini integration yet
The project provides Lead Detective, Suspect Interviewer, Evidence Analyst and Devil's Advocate roles that help track leads and challenge theories. Crucially, the developer states the advisors currently run deterministic built-in rules: the optional Gemini phrasing connection remains a stub. It would be inaccurate to call CaseZero a fully generative multi-agent detective game.
Gameplay is built around visiting locations before securing records, presenting evidence in interviews, checking contradictions in a timeline and linking a theory to the two required system logs. The rules-based case engine judges the accusation, and an incorrect choice leaves the investigation open. A correct choice closes the case with an explanation and score.
The developers say play is available end to end, but sessions are stored in memory and reset when the server restarts. The demo URL is a hosted preview rather than a verified commercial launch. GameSlash reviewed the open-source project and screenshots but has not independently play-tested the case or confirmed hosting uptime.
