A tricky tetrahedral puzzle!
Developed several years prior to the Rubik's Cube craze of the 1980s, The Pyraminx is a tricky tetrahedral puzzle. After scrambling, twist the brainteaser along its multiple axis points to align pieces of the same color on the same side. Simply put, it's like a Rubik's Cube in the shape of a pyramid. A worldwide best seller, the Pyraminx has sold over 90 million units since its introduction.
