Mental Rotation

Can your mind rotate objects in 3D space?

• Two shapes appear side by side.
• Decide if the right shape is the same shape rotated or a mirror image.
• Shapes get rotated further as rounds progress.
• 12 rounds total. Take your time — accuracy counts.

Mental rotation is a core measure of spatial intelligence. The ability to mentally manipulate objects in 2D and 3D space predicts performance in engineering, surgery, and navigation, and correlates with overall spatial IQ.
