TURNED, OR FLIPPED?

Spin it in your head.

Two shapes appear. The right one is always the left one turned by some angle, and sometimes it is also flipped over like a reflection. Say which: Same if turning alone could make them match, Mirror if it takes a flip.

After every answer the right shape swings back onto the left one, so you can see exactly how they relate.

60-second Sprint
Shapes start with 5 squares and grow to 8 as you get more right. Each new pair appears the moment the last one is judged.
Scoring
A right answer is worth 10 points, or 15 if you answer within 1.5 seconds, times your multiplier. The multiplier grows every 5 right answers in a row, up to 4×. A miss costs 2 seconds and resets it.
