🔐 Rotate Lock
A lock and a turned key. You can turn the key but not flip it: does it fit, or is it a mirror image?

What it practises
- Spatial & visual perception: Judging angles, rotations, paths and positions in 2D and 3D space.
- Problem-solving & planning: Planning ahead, switching strategies and working out cause and effect.
Spatial puzzles practise spatial reasoning inside the puzzle; transfer to other tasks is not promised.
Quick lesson: Turning shapes in your head
Turning a shape keeps it the same shape; flipping it makes a mirror image, like a left and a right glove. To compare, people imagine turning one shape until it lines up, which takes longer for bigger turns.
Check question
A left glove is turned upside down. What is it now?
- A right glove
- Still a left glove
- A mirror image
- It depends on the angle
Answer: Still a left glove. Turning never changes left into right; only flipping does.
