Each face of the Master Pyraminx consists of 16 triangles (compared to 9 in the Pyraminx) making it a harder puzzle to solve. While the original Pyraminx has only about 75 million possible combinations, the Master Pyraminx has about 217 quadrilion of them - a number that is much closer to the Rubik's Cube's 43 quintillion possible combinations. The solution to this puzzle relies heavily on the original Pyraminx solution and has some parity cases.
Since this puzzle is not an official WCA puzzle, there is no official record for fastest solve. However the unofficial record belongs to Fedor Abaev from Russia and is 18.01 seconds.
