This is something no one needed. Maybe not even me. But I did it anyway.

The original question was how to make a fair choice from 7 things using only D6.
It got out of hand. I have a "sort-of" solution that maps to the polyhedral dice (as well as lots of other prime numbers and stuff.)
When playing a game using D6 -- and only D6 -- we're sometimes confronted with a need to make a selection from equiprobable items. For example, pick a random day of the week: 7 choices, but only 6 sides to a die. What can we do? How can we select fairly among …

I went deep into OpenD6, chasing an idea through a maze of strange shapes. See this extract from a Jupyter Notebook: Area Effect Aspect Volume Computations. It was a lot of fun to uncover two errors in the rules, and work out what could have been used instead. TL;DR …

I've got a DSL that covers a number of bases. The corpus of almost 400 spells all seem to work.

whee! #TTRPG i have been working on with my son is out: https://senchawizard.itch.io/peopletown
