The Pyraminx is a triangular pyramidshaped (or tetrahedron) puzzle. The parts are arranged in a pyramidal pattern on each side of the puzzle. The layers can be rotated with respect to each vertex, and the individual tips can be rotated as well. It was designed by Uwe Mèffert in the early 1970s.
In the early 1970s Uwe Mèffert experimented with slicing polyhedra into symmetric slices and attaching them with rubber bands to a center ball. His wooden puzzles eventually end up in a drawer halfforgotten. It was only when the Rubik's Cube craze hit in the early 1980s that Mèffert brought it to the attention of a toy company. Over 10 million pyraminxes were sold by Christmas 1981, and 90 million within 3 years.
The pyraminx is a tetrahedron trisected by planes parallel to each face. This means there are 4 axial pieces, 6 edge pieces, and 4 tips. The pyraminx can be arranged into 75,582,720 possible positions. This sounds a lot compared with the 2x2x2 Cube which has 3,674,160 possible positions. However, solving the tips is trivial, and ignoring these reduces the possibilities to 933,120 positions. In addition, the axial pieces can be easily rotated so that their colors line up with each other, reducing the problem to just the six edge pieces with 11,520 possible positions. This makes the pyraminx one of the simplest of the twisty puzzles.
Variants
 Tetraminx. The simplest variant is the Tetraminx which is equivalent to the Pyraminx but without the tips.
 Master Pyraminx. The Master Pyraminx is a 4layer pyraminx with 16 triangles per face. It has about 2.17225 × 10^{17} possible combinations.
