Turtle Soup (海龟汤)

Problem

Lateral-thinking "situation puzzles" (海龟汤) are a beloved social game, but they need a sharp, patient host who can answer free-form yes/no questions and know when a player has cracked it — something a static puzzle list can never do.

Approach

Built a mobile game where an LLM plays the host: it interprets open-ended player questions, answers consistently against a hidden solution, and adjudicates the reveal — in both English and Chinese from a single design.

My role

Sole builder — product design, prompt/agent design, app development, bilingual content, and App Store release.

Result

Shipped and live on the iOS App Store.
