Correct, Treehouse is technically both, as it can be played with a monochrome stash. >> * A game is tagged as both ONLY IF it has variants that allow for the >> use of either a SS or TH. >Is there any "single stash" game that couldn't also be played with a >Treehouse set? Oh, hmm, I guess games that require more than 3 opaque >pieces? ...or any game that is hamstrung by opaques: Take That! http://icehousegames.org/wiki/?title=Take_That! Tic Tac Doh! http://icehousegames.org/wiki/?title=Tic_Tac_Doh! 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! David
