Scramble the pyramid and reorganise it so that only one colour shows on each side
This cube is coming out in the 40th anniversary year of Uwe Meffert first designing the original Pyraminx (which has sold millions).
This is a well made rotational puzzle, the layers move very smoothly. It is not to be used for speedcubing but it is still a nice puzzle to work with. The stickers are very high quality as you would expect from a Meffert's puzzle.
The reason why it is called Professor Pyraminx is because the original Pyraminx has 3 layers, like a Rubik's Cube and this one has 5 layers, like a Rubik's Professor Cube.
