About Scioly.rocks

Practice mineral identification with 24,268 real images.

What is this?

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. It’s built to improve real identification skills—not just image recall.

How do I use it?

  1. Go to the home page.
  2. Look at the image and type the mineral name in the box.
  3. Press Enter (or click Answer) to submit.
  4. An alert shows whether you’re correct and reveals the answer if not.
  5. Press Enter again to load the next image.

Why use this instead of Minerobo?

Minerobo (a Discord bot) is great for quick drills, but it has far fewer images per mineral. Scioly.rocks averages ~282 images per mineral, so you’re less likely to memorize a small set of photos and more likely to learn actual ID skills across different samples, lighting, and forms.

  • Minerobo: convenient in Discord, limited images → easier to memorize.
  • Scioly.rocks: large, varied image pool → better transfer to real IDs.

Note: this site currently focuses on minerals. If you want to practice rocks, Minerobo may suit that need—though adding rocks here is on the roadmap. Interested in helping? Reach out!

What accuracy should I expect?

Many images are intentionally challenging. Most users score ~20–60% while learning; ~35% is typical overall. Don’t be discouraged— the goal is steady improvement and stronger field ID skills.
