Dungeon World Dice Statistics

Well actually they're about any 2d6±3 game. I like this kind of tables—they help you understand more clearly how and why the dice work—and thanks to anydice.com I put together the numbers.

Mod. 6- 7-9 10+
-3 ~83.34% ~16.67%
-2 ~72.23% ~25% ~2.78%
-1 ~58.34% ~33.33% ~8.34%
±0 ~41.67% ~41.67% ~16.67%
+1 ~27.78% ~44.45% ~27.78%
+2 ~16.67% ~41.67% ~41.67%
+3 ~8.34% ~33.33% ~58.34%
edit: corrected the embarassing +2.54 error on the first 6- rows :P

That sweet, sweet +1 is right where you want to be.  +2 if you're scared of your GM, I guess.

What I really like is that I can't do the probability in my head during the game, but now I can't unsee your table! ;)

I also like that the chance of partial stays high across the main rolling zone.

For me these two are part of the genius of the original AW design that's flowed through to DW.

Similarly,  once I made a Lady Blackbird table - I couldn't unsee it either.  Game changer but not game breaker.

I would have edited the first post, but I'm not allowed to do it :(

I went deeper and summed up the chances for a hit no matter if strong or weak, and the chances to have a 12+.

Mod. 6- 7+ 7-9 10+ 10-11 12+
-3 ~83.34% ~16.67% ~16.67%
-2 ~72.23% ~27.78% ~25% ~2.78% ~2.78%
-1 ~58.34% ~41.67% ~33.33% ~8.34% ~8.34%
±0 ~41.67% ~58.33% ~41.67% ~16.67% ~13.89% ~2.78%
+1 ~27.78% ~72.22% ~44.45% ~27.78% ~19.44% ~8.34%
+2 ~16.67% ~83.33% ~41.67% ~41.67% ~25% ~16.67%
+3 ~8.34% ~91.67% ~33.33% ~58.34% ~30.56% ~27.78%

It burns! Ah! I can't unsee it!

(Nice work.)
