Hey Product Hunt š
Rocksday is a free daily geology puzzle: same mystery rock/mineral/gem for everyone, six guesses from a zoomed-in photo. Wrong guesses zoom out and unlock scientific clues (type, luster, Mohs, structure, locality).
No signup, no paywall. There's a 300+ specimen library, compare pages, and an archive when you're done.
I'd love feedback from rockhounds and puzzle fans ā upvote if it looks fun, and tell me what you'd want next (fossils? more hard mode?).
