I really like Fate dice (or Fudge dice if you prefer).
For fun, I’ve calculated probabilities to compare if they wouldn’t be too far from 2d6. Turns out it’s totally doable (well at least for me).
Notable differences:
Chances of getting a “10+” (critical success) are a bit higher with Fate Dice when you start having bonus of +2 or more (which is fine by me, heroes are awesome, right?).
Here, if you’re curious.

4dF is very nearly 2d4 – 5.
Good chart. I think the probabilities line up enough to work just fine.
What about d6-d6? It’s supposed to have a comparable curve to 4dF.
It’s certainly doable. But as you determined, any mods significantly skews the results in the hero’s favor. I would be tempted to start with (-4 to 0, 62%) as a fail, (+1 to +2, 32%) as a partial, and (+3 or more, 6%) as a full success. A meager +1 would shift that to (38%,43%,19%) which is close to the default 2d6.
If you check sheet 2, I’ve already made that calculation and it seems numbers are farther than if you do 6- on a 0-, partial on a 0-1 and 10+ on a 3+
Well, they are closer to 2d6 for when you have bonuses than the first method but they screw the players big time when you get minuses.
I cant recall, do minuses are rare in PbtA?
Am I right to say usually checks are between -1 to +2 ?
Todd Zircher Well you know what, I’ve recompared and even there’s less similarities in probabilities than the first table, I think I prefer the second one because it makes penalties more costly and is smoother on when you have bonuses.
[Enlarges browser window] Oh hey, there’s a sheet two. Heh, consider your math verified. 🙂
Haha I actually suck hard at math lol bless anydice
