Non-transitive Grime dice

£13.99


In this set of dice, green tends to beat red, red tends to beat yellow, yellow tends to beat blue, and blue tends to beat purple. So you might think green is the best dice and purple is the worst. But here's the twist: purple beats green! There's no best dice. Use them to win money or drinks or respect or whatever. 

They’re called Grime Dice because they were discovered by our very own Dr James Grime. There’s a lot more to these dice. Read all about them in James Grime’s article.

When you double up the dice, things get even weirder. That's why we sell them as a set of 10, two of each colour.

We also sell larger quantities of dice as schools sets, which come with lesson plans and activity worksheets to run probability and statistics sessions around the dice.

Set of 10 = 1399 pence (the 222nd prime number) = £13.99
