A real-time multiplayer drawing game where up to 4 players race to draw the same prompt, and an AI judge scores whoever it recognizes first.
Each game consists of 10 rounds drawn from a pool of ~300 simple noun prompts (e.g. "panda", "tennis"). Players draw simultaneously on their own canvas, and their drawings are periodically sent as snapshots to a Gemini-powered AI evaluator. The AI isn't told the answer directly — it picks from the full prompt pool, making accurate drawing essential. The first player whose drawing the AI correctly identifies wins the round and earns a point. The round immediately ends for everyone, and the next begins. Highest score after all rounds wins.
