About Scioly.rocks

Practice mineral identification with 24,908 real images.

What This Site Does

Scioly.rocks is a fast practice tool for Science Olympiad Rocks & Minerals competitors. You’ll see a mineral photo, type your guess, and get instant feedback.

The large image pool minimizes memorization and builds identification skills.

How to Practice

  1. Pick a mode: Full List, Regionals, Starter, or USESO.
  2. Look closely at the photo, type the mineral name, and press Enter.
  3. The result overlay shows the answer plus common facts about each mineral to help you internalize core properties.
  4. Press Enter again—or click Close—to hide the overlay and load the next photo.
  5. If you want to skip, submit a blank guess. It counts as incorrect.

Why use this instead of Minerobo?

Minerobo (the Discord bot) is great for quick drills, but it keeps a much smaller library per mineral. Scioly.rocks averages roughly 282 images per mineral, so you see different habits, lighting, and sample quality instead of cycling through the same few pictures.

  • Minerobo: convenient in Discord, lighter on images → easy to memorise.
  • Scioly.rocks: big, varied pool of 24,908 photos → better transfer to actual ID.

This site is mineral-only for now. If you want rocks, Minerobo still covers them.

Accounts & Stats

  • Guest practice: your totals stay in browser cookies. Refreshing, switching pages, or closing the tab won’t erase the current day.
  • Google sign-in: syncs your history so per-mineral accuracy, streak, and daily activity follow you across devices.
  • Signing in for the first time imports any guest progress on that browser so you don’t lose earlier work.
  • The Stats page shows overall numbers, per-mineral accuracy, daily bars in Pacific Time, and a streak indicator.

Daily Totals & Streaks

  • "Answered today" and "Correct today" track your progress for the Pacific Time calendar day.
  • Streaks increase when you log at least one answer on consecutive days.

Starter Mode

Starter mode is designed for people starting out with ID. Each mineral in Starter mode has only 10 hand-selected images that showcase key identification features without overwhelming variety.

  • Recurring images help get the hang of mineral ID when starting out.
  • Great for building confidence before moving to the full image library.
  • Only shows minerals on the Regionals list
  • Stats track separately—see your progress in Starter mode vs. other modes on the Stats page.

What accuracy should I expect?

Many images are intentionally challenging. Most users score between 15% and 60%; The net average on scioly.rocks is around 33%. Don't be discouraged—the goal is steady improvement and stronger ID skills.
