Sometimes, you have to roll a hard six.
-Commander William Adama, Battlestar Galactica
“Rolling a Hard Six” refers to rolling double threes in the game of craps, an outcome that pays 7 to 1 but only has a three percent chance of occuring.
It was popularized in geekdom by the quote above. I’ve also heard it used to express doing something difficult but necessary, something risky but rewarding, etc. It’s kind of like rolling a natural twenty… if your a d6 kind of person.
Also it’s a blog about traditional game design.
