# 75 mm Puzzle Ball **Composed of 60 identical quadrilateral tiles.** The ball is rooted in the [regular icosahedron](https://en.wikipedia.org/wiki/Regular_icosahedron) and its mirrored form, the [regular dodecahedron](https://en.wikipedia.org/wiki/Regular_dodecahedron). Each of the 20 triangles of the icosahedron are crafted from 3 puzzle tiles, and each of the 12 pentagons of the dodecahedron are constructed from 5 puzzle tiles. **Guidelines for Assembly** Always push the "noses" outward into the corresponding holes, even if multiple "noses" and holes are already in place (twist tile accordingly). For the final tile, you may need to broaden the shape at the inner surface of its hole along the long edge using a knife. This will allow you to push the hole onto the corresponding nose.
