Surprising dice

In a recent issue of my newsletter, The Magnet, I wrote about a fascinating curiosity called nontransitive dice. It’s a set of three nonstandard dice with confounding rock-paper-scissors behavior. No matter which of the three dice your opponent chooses, you can always pick one of the other two dice to beat it. I made my own nontransitive dice on a 3D printer, but they are also available on Amazon if you want a set. — MF
