Pyramorphix

The Pyramorphix (sometimes misspelled "Pyramorphinx") is a tetrahedral puzzle similar to the 2x2x2 Pocket Cube. The core turning mechanism of it is almost identical to that of the 2x2x2 Pocket Cube. It has a total of 8 movable pieces to rearrange. There are 4 faces (the colours of which are yellow, blue, green, and red), 4 corners, and 4 centers. Each corner has 3 colours on it, while each center only has one colour. There are 136,080 possible permutations. The Pyramorphix is commonly mistaken for a Two-Layer Pyraminx, a trivial puzzle that can be solved by merely twisting the corners. However, that is not the case because, unlike the Pyraminx which turns 120 degrees, the Pyramorphix turns 90 degrees like a Rubik's Cube.

The Pyramorphix's original name was "Junior Pyraminx", but it was later altered to reflect the shape-shifting qualities of it. The word "junior" also made it seem undesirable for adult costumers.
