A sphere is bad, it rolls away. The shape from the article would be better, but it is too hard to manufacture. And weighting is cheating anyway. The best option for a D1 is probably the gömböc, which is mentioned in the article.


Technically, a gomboc is a D1.00…001.


Any normal die could also land on an edge.


It’s infinitely unlikely to do so, a set of measure zero.


Just as with the gömböc. Though the latter balances on only one unstable axis while a D6 die does so on 20 (12 edges and 8 vertices).


Vertices aren't axes! They have the wrong dimensionality.


Let's instead call the balance things in question "balance things".
