The dodecahedron extends familiar edge-and-corner reasoning, with solving stages and a comparison to Kilominx and larger minx variants.

Twelve pentagons instead of six squares
Megaminx has twelve pentagonal faces and 72° face turns. The standard puzzle has twenty corners and thirty edges; centres identify face colours. The linked solution describes a specific layer method.

1 · Star and first layer
Build a five-edge star around a centre, matching each side colour to its neighbouring centre. Insert the five corners between their three correct colours. This parallels the 3×3 cross and first layer, but with five neighbouring sides.
2 · Work around successive belts
Insert edges and corners around the completed face. Reorient the whole puzzle between insertion sequences to reach the next working side. Keep an unsolved buffer region and check completed neighbours after each insertion. Do not assume another model’s colour chart matches yours.
3 · Last face and relatives
On the final face, orient edges, permute edges, then position and twist corners. Algorithms must respect Megaminx geometry; its U turn has a different angle from a 3×3 U. Kilominx focuses on corners, while Gigaminx and Teraminx add centre and edge work. These are separate models, not settings in our edition.
