A 3-D spatial puzzle: the corner dots of a solid are shown with some edges pre-drawn, and you complete the named solid by drawing its missing edges between the right dot pairs.

How do I draw an edge?

Tap one dot and then a second dot, or drag from one dot to another. If the pair really is an edge of the solid it locks in as a solid line; keyboard players can Tab or arrow between dots and press Enter.

What counts as a mistake?

Connecting two dots that are not joined by an edge of the target solid. The wrong line flashes and shakes, and after three mistakes the round is lost and the full wireframe is revealed.

How does it get harder?

Higher difficulty unlocks bigger solids · from the tetrahedron up to the octahedron and pentagonal prism · and leaves more edges missing, while always keeping enough scaffold to recognise the shape.
