The following are listed in order from easiest to hardest (to the best of my knowledge): Pyraminx Star: Easiest of all pyraminx?? A simplification of the popular pyraminx because of the little uni-coloured (usually grey or silver) tetrahedrons on the 3 middle pieces of each face. Effectively all middle pieces on this pyraminx are the same colour! Snub Pyraminx: Same as standard pyraminx with tips removed Popular Pyraminx: The standard pyraminx of which appeared in vast quanities after the cube caught on. Senior Pyraminx: This is a mystery puzzle. No one seems to know anything about it, yet Turner-Smith's book refers to it and gives the maximum number of moves for it! It is between the Popular Pyraminx and Master Pyraminx in difficulty. Master Pyraminx: All the moves of the standard pyraminx plus 180 degree turns of the edges (just the strip, not the whole face) 446,965,972,992,000 combinations.
