You'll see a shape on the left and a turned copy on the right. Decide whether the right-hand shape is the SAME shape simply rotated, or a MIRROR image of it. Answer as many as you can in 60 seconds.

What it measures
Mental rotation — made famous by Shepard & Metzler in 1971 — measures spatial visualisation: your ability to picture how an object looks when turned in your mind. It's strongly linked to performance in STEM and navigation tasks.
Honest note: Practising mental rotation does tend to improve mental-rotation performance, a genuinely useful spatial skill. We make no broader claims.
What's a good score?
Most players land 14–24 correct in 60 seconds; over 30 is strong spatial sense. The percentile we show is an estimate based on typical distributions, not a clinical norm.
FAQ
How do I tell same from mirror?
A mirror image can never be made to match by rotation alone — it's flipped, like a letter R seen backwards.
Why letters?
Letters are asymmetric, so the mirror is unmistakable once you spot it — and they rotate cleanly.
