Pyraminx

A Pyraminx is a tetrahedron-shaped (not a pyramid!) twisty puzzle with four triangular faces, each divided into nine smaller triangles. It has 14 movable pieces: 4 tips, 6 edges, and 4 centres. The goal is to twist and turn the pieces to align all colours on each face.

The Pyraminx was invented by Uwe Mèffert in 1970. It was later mass-produced and released commercially in 1981.
