Correct, Treehouse is technically both, as it can be played with a
monochrome stash.

...or any game that is hamstrung by opaques:

Admittedly, you could play them with a Treehouse stash minus the
opaques, but that's a 20% reduction in the number of available pieces,
which would surely affect play--I'd expect a lot more tie games, with
an even number of each size.

SO, how about these revisions:

* If the game uses no more than 15 pieces, and color is irrelevant ***or
the use of opaques hinders play***, then it's "single stash."

* If the game uses no more than 15 pieces, and color is relevant or is
***critical*** to distinguish piece ownership during play, then it's
"Treehouse set."

Closer? Or do you have a set of counter-definitions that "hook into"
simpler ways to distinguish?

Thanks!
