Unlike the standard d4, which is a regular tetrahedron, this truncated tetrahedron design allows the numbers to face up.
This d8 rolls more readily than the standard regular-octahedron design.
The rhombic dodecahedron is closely related to both the cube and the octahedron.
Each face in this polyhedron is kite shaped. In our opinion, this shape rolls better and is more attractive than the standard d24.
The world's first mass-produced d60. Each face in this beautiful polyhedron is kite shaped. A computer search was used to distribute the numbers as uniformly as possible.
