The goal of the geography puzzle Worldle by @teuteuf is to name a country in six or less guesses given only its outline. I really enjoy playing it, but it lacks a way to play ones I've missed.
Until @teuteuf includes a way to play previous days' puzzles, you can use the Wayback Machine to play older ones. However, it's missing a number of puzzles prior to Feb 6, and can be slow or unreliable.
