The Pyraminx is a triangular pyramid-shaped (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 Meffert in 1970, but was nothing was done with the design until he brought it to Hong Kong for production after seeing the success of the Rubik's Cube.
The Pyraminx has 4 axial pieces, 6 edge pieces, and 4 trivial tips, and a total of 3,732,480 different possible combinations. Every position can be solved in a maximum of 11 moves.
The world record for the fastest single solve is 0.91 seconds held by a Dominik Gorny. The World record average is 1.86 seconds held by Tymon Kolasiński.
- The maximum number of moves needed to solve a Pyraminx is 11.
- The Pyraminx is the only WCA event that have 4 faces.
