DODECA SRD v1.0
A downloadable game
If you like rolling d12s and tinkering with randomizing microchoices AND you want to make a solo or GMless tabletop rpg...
Hello?
I think everyone left.
Except you! Thanks for sticking around. I know what you're here for. Sicko.
Here's what's inside the DODECA SRD:
- A unique but easy-to-use d12 table to make games that don't need a GM
- Turn your idea into a playable game by choosing a control group, 3 encounters, a thematic opportunity, and a critical success
- Two detailed examples of my own work with the system so you can see how I approached using DODECA
- Licensing terms (it's open license CC BY 4.0! Free for commercial and personal use, as long as you give me credit somewhere in your game)
If you have any questions, head over to Bluesky where my handle is @titanomachyrpg.com, thanks!

i feel strangely targeted as a forever dm that loves the d12
delighted to sate that desire!!
Hiya! I just picked this up as part of the "No ICE in CA" bundle. The idea of using primes as a specific result blew my mind. Anyway I put together a little table of the regular d4-d20s, their probabilities of a critical success (1), their probability of hitting a prime, and the sum of the two (I was thinking of it in terms of a prime being a success, and you can use larger dice for more difficult attempts).
I then appended the same 1 and prime probabilities for the weirdo DCC dice (d5-d30), for people who might want to use those.
It's not the same as Dodeca, as it wouldn't be an oracle, but rather a resolution mechanic for a game with a GM, though now that I'm thinking about it, certainly a solo player could use it if they wanted to for resolutions of attempted actions. They could, for example, replace the percentiles in Mythic based on the odds determination, if a person prefers to use a bunch of different dice...
Anyway, here's the table. I may write this up as a one pager and post it on its own, I don't know.
THIS IS SO FREAKING COOL. Yeah, please write it up and post it! Thank you for the kind words and for sharing this with me!! Very very cool
Thanks...but I screwed up my formulas, ha. It's not as good in actuality--the lowest probability is still too high. Even if you include d100, the lowest probability of success is still 0.26. So, hrm, back to the drawing board...there may be something here though, I'll keep playing with it and I'll let you know if I write anything up.
ah dang. but yeah keep me posted!!
My first ever published game was a titanomachyRPG SRD, and you better bet I'm always on the edge of my seat to see new things~!
ty Chubby Crow!! always love to see what u make with my stuff!
Aw heck you're too kind!
You are doing great stuff and empowering people to do their stuff too
thank you T_T
I like it! I'm going to try to use this to make tables for a solo game I'm working on
wonderful!! best of luck and thanks!!
I see a lot of potential with this. Kinda reminds me of mazes, but boiled down to its essence. Giving it occasional multiple choices, adds a layer to your already cool quantified results system from caltrop. Will be interesting to see what more clever people than I will do with it.
