Not quite, I think that there are ~119(ie. more than 100) different
chits.
Hence the D12-D10 combination.

Again, not exactly my intention. You would only have, at most, five
different colors. Each _color_ corresponds to a chit draw. Basically
the dice work in tandem. The major speed increase comes from the
fact that you can "draw" all of the required chits at the same time
with a single handful of dice. Also, it's not the same as rolling
X times on the one chit table. Chit draws are not statistically
independent, whereas a d10000000000 is statistically independent.

Finally, there is another advantage, losing one or more chits
changes the odds. You can't lose one facet of a die ;)

Cheers,
Tony.
