Rocksday
Daily rock & mineral guessing game — free, no signup
Guess the rock, mineral or gem of the day from a zoomed-in photo in six tries. Wrong guesses zoom out and unlock scientific clues. Free browser game with a 300+ specimen library, compare pages, and archive. No account needed.
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 — upvote if it looks fun, and tell me what you'd want next (fossils? more hard mode?).
