Solstice Turing Simulation is a responsive web application that recreates elements of Alan Turing’s “imitation game” as an interactive 3D experience. Presented with a stylized June Solstice beach bonfire setting, the game asks players to examine linguistic patterns and behavioral cues to determine which of three voxel entities is actually a rogue artificial agent posing as a human. The challenge is limited to 10 interactive turn cycles.\n\nAccording to the project description, the system uses a decoupled architecture that separates a graphics layer from an AI layer. The graphics side is implemented with a Three.js engine, featuring an interactive 3D viewport, camera orientation tracking, orbit controls, and lighting tuned to a bonfire-style illumination effect. The AI side integrates Google AI Studio and the gemini-2.5-flash model for multi-turn, state-retaining dialogue.\n\nThe project also describes “system-level prompt engineering” to isolate each entity using separate contextual instruction blocks, including guidance for occasional “context slips” and self-correction. An AI Certainty Meter is then computed from real-time text logs to scale over the 10-turn countdown. The developers report the June Solstice Hackathon submission is operational, with a live deployment and a public GitHub repository.
