Reddit user builds mobile game with GPT-6 in three days

On October 23, 2026, Juejin published an article titled "Building a Mobile Game with GPT-6 in Three Days: A Four-Step Practical Guide for Beginners", introducing a Reddit post that drew widespread attention. According to the article, the Reddit poster is an overseas office worker with no coding experience and no prior exposure to 3D modeling, who claimed to have built a mobile game within three days using GPT-6. The post reportedly received over ten thousand upvotes and more than two hundred comments. On the basis of that post, Juejin put together a four-step practical walkthrough that beginners can follow. As of now, this is the only publicly available report on the matter, and the claim rests solely on the poster's own account. No further developments or independent verification have surfaced in publicly available sources. Notably, the Reddit post itself and any direct engagement with it remain inaccessible to this summary, as only the Juejin article was available for review. No other details about the game, the development process, or the poster's identity appear in the available material.
