# Turing’s Light: Escape the Enigma – June Solstice Game Jam Submission > Source: > Published: 2026-06-21 18:54:54+00:00 ## 🎮 The Game **Turing’s Light: Escape the Enigma** is an AI‑powered puzzle game where you wake in a dark room and rely on ECHO, a ghostly AI echo of Alan Turing, to fire beams of light into the void. - **Live Demo:** [https://turing-light-game.netlify.app](https://turing-light-game.netlify.app) - **How to Play:** Type answers to Turing‑themed riddles generated live by Google Gemini. Each correct answer fires a beam of light that reveals a hidden digit. Collect all four digits, pass the Imitation Gate (a Turing Test), and enter the sequence to win. - **Theme Connection:** Light vs. dark is the core mechanic – you literally push back the night with each correct answer, culminating in the solstice sunrise. - **Built with:** HTML/CSS/JS, Canvas, Web Audio API, Gemini API (gemini-2.5-flash) ## 🤖 Best Google AI Usage The game uses the **Gemini API** as its central mechanic: - Gemini generates a unique, contextual riddle each round, tailored to the player’s difficulty. - It evaluates free‑text answers with semantic understanding, not exact matching – accepting synonyms, partial phrasing, and clever interpretations. - At the Imitation Gate, Gemini improvises a sincere answer to "What does it mean for a mind to be truly free?" and the player must distinguish it from a scripted impostor – a literal Turing Test within the game. - Without the AI, the game falls back to a small archive, but the full experience – dynamic riddles, adaptive hints, and the climactic gate – only works with Gemini. ## 🎥 Demo Video [https://youtu.be/CtjprKqM59E](https://youtu.be/CtjprKqM59E) ## 💡 Development I built the entire game solo, from a single HTML file, using vanilla JavaScript and the Canvas API. The Gemini integration was done via a simple `fetch` call with prompt engineering to control tone, difficulty, and output format. The solstice theme is embedded in every layer: the gauge, the lives (sparks), the colour palette, and the final sunrise. This is my entry for the **June Solstice Game Jam**.
