Mystery Shape is a fun puzzle for children, which also develops the ability to rotate and flip objects inside their head.

The objective is to fit together pieces as if they belonged to a Jigsaw Puzzle. But more than a Jigsaw Puzzle, pieces are shaped differently each time, and can be one of 24 orientations between rotating and flipping. 

When all pieces fit together, they form a silhouette of an every-day object. There are ten levels altogether, with progressing level of difficulty.
