D66? RoC?

So what’s with the name of my blog, anyway?

I don’t think I ever really explained what these mean, so I’ll explain here.


Astute gamers know that there’s no such thing as a 66 sided dice, unless you’re playing in Rilyeh with non-euclidean dice (of which I have a dice-decahedron full of). Rolling a d66 is achieved by rolling 2d6 and interpreting the results in one of two ways:

  • Bouken (Shinobigami, etc.): The lowest dice becomes the tens digit while the highest dice becomes the ones digit. a roll of a 1 and 4 becomes 14, 3 and 2 becomes 23, and 4 and 4 becomes 44. Note that there is no 21, 31-32, 41-43, 51-54, or 61-65.
  • F.E.A.R. (Tenra Bansho, Monotone Museum, etc.): One dice is designated as the tens and the other as the singles digits. This allows for the full 36 different outcomes, but can get annoying if you don’t have 2 different types of dice.

d66 charts are usual accompanied by:


Roll or Choice. D66 RoC charts are usually life path, personality, or background charts; things that define a character and has an impact on role-playing. If a player has a strong image of a character floating in their head, they can choose the best fit option, otherwise they’ll be rolling the dice to see what character they’ll be making.

Often times, a d66 RoC chart has an option that is impossible to roll–a roll of 00, for example. In these cases, a player must choose the option, obviously, and these are usually the more difficult role-playing challenges or character types that are rare.
