About this game
Oracle 20 is an original browser guessing game staged inside a handcrafted clockwork fortune booth. Silently choose one of thirty illustrated relics, then answer Yes, No, or Unsure while the mechanical oracle narrows the cabinet with a deterministic information-gain decision tree. The first question is ready immediately, every answer updates the remaining possibilities, and the oracle must name the relic within twenty questions. If an answer path becomes contradictory, the game does not stall or fail silently. It reveals the first mismatch, explains what no longer fits, and offers a clean recovery. Players can hide the relic cabinet for pass-and-play sessions, reject a premature guess, consult again, or share the result without revealing the chosen object. The carnival gouache scene, brass owl mechanism, parchment typography, tactile answer controls, and visible candidate trail give a familiar party-game rule a distinctive authored world. Everything runs locally, with keyboard and touch controls and no signup, API key, download, or model latency.
Oracle 20 sits in the AI Chat Games section. The main appeal is flexible interaction: your wording, timing, and willingness to test the system shape the session. The tags #original, #twenty-questions, #guessing, #oracle describe the fastest way to understand what kind of session to expect.
Oracle 20 can run directly inside AI Game Lib, which makes it suitable for quick testing without leaving the directory.
