Michael de Podesta has been doing the math on "Grime Dice" -- six sided cubes whose sides average out to 3.5, but whose face values are all radically different:
The interesting thing about these is that the odds of one die beating another are simple to calculate, but shift radically once you start rolling dice in pairs. It's a beautiful piece of counterintuitive probability math:
The amazing property of these dice is discernible when you use them competitively – i.e. you roll one dice against another. If you roll each of them against a normal dice then as you might expect, each dice will win as often as it will lose. But if you roll them against each other something amazing happens.
- Dice A will systematically beat Dice B
- Dice B will systematically beat Dice C
- Dice C will systematically beat Dice A
So the fact that Dice A beats Dice B, and Dice B beats Dice C does not ensure that Dice A will beat Dice C. Wow!
And how about this: If you ‘double up’ and roll 2 Dice A‘s against 2 Dice B‘s – the odds change around and now the B‘s will beat the A‘s ! Is that really possible? Well yes, and just to convince myself I wrote a Spreadsheet (.xlsx file) and generated the tables at the bottom of the article. If you download it you can change the numbers to try out other combinations.

“Information Doesn’t Want to Be Free” is my 2014 nonfiction book about copyright, the internet, and earning a living, and it features two smashing introductions — one by Neil Gaiman and the other by Amanda Palmer.
5 years ago, Boing Boing described James Gleick’s The Information: A History, A Theory, A Flood as “a jaw-dropping tour de force history of information theory… The Information isn’t just a natural history of a powerful idea; it embodies and transmits that idea, it is a vector for its memes (as Dawkins has it), and […]
The Pocket Tripod PRO had massive Kickstarter success in 2013, raising almost $85,000 in a single month. But this isn’t just another case of pre-release product hype. This ingenious little device folds out from a credit-card-shaped plastic slab into a sturdy stand with a surprisingly wide range of motion. In portrait orientation, your phone slides […]

The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
