Shape Fusion

Figure out which shape can be assembled from the 2-4 rotated pieces shown.

How to play

You're shown a handful of puzzle pieces. Mentally fit them together — including rotating them — and pick the completed shape they form from the options.

• Pieces may need to be rotated in your head before they fit together.
• Every piece shown is used exactly once in the correct answer.
• Choose your difficulty before starting — higher difficulty means more and larger pieces.

Why this matters

Mentally assembling rotated pieces into a whole is a close analogue of the Block Design subtest that has appeared on Wechsler scales since their original construction — one of the most durable visuospatial-construction measures in clinical assessment.
