Object: Mix up the cube and put it back to the start. The Meffert's Pyraminx Diamond is an extension of the original Pyraminx Duo puzzle. The tips can be rotated and the adjacent centers follow along as well, but nothing is truly simple when there are not just four sides to match, but eight—it’s double trouble! This puzzle’s limited difficulty, combined with its attractive look and high fiddle factor, makes it a perfect puzzle gift for beginners.
