But where would GPT have sourced information about how the game works from? That page only has screenshots, I suppose maybe there's a subreddit or something for it as well. Even if there's a bunch of info on it it's still incredibly impressive for it to parse those game rules and turn it into workable code.

Would be nice if GPT could dump the source of how it came to such a solution, if it generated the game by random chance via combining various unrelated chunks of text and mixing up the rules, or if it used some text describing the game you linked.
