Show HN: Fermi – A Wordle-style game for order-of-magnitude thinking

I always thought it was cool when someone could make a plausible estimate from reasonable guesses. I recently learned that these are sometimes named after Enrico Fermi, the famous physicist, and its the same technique used to create his famous Fermi paradox.

You build a rough logic chain using a few sliders and fixed quantities (e.g. weeks per year), and the goal is to get within an order of magnitude of the true answer. The math is simple; the thinking is the game.

Would love feedback.

Show HN: val – An arbitrary precision calculator language

Wrote this to learn more about the `chumsky` parser combinator library, rustyline, and the `ariadne` error reporting crate.

Such a nice DX combo for writing new languages.

Still a work in prog
