I was leaning towards the idea that switching the White & Black trios would be good, but after hearing Andy's reasoning, I now support him on that point.
As for the rules for TreeHouse, I do find them a bit difficult as many others were also seeing.
I will focus on the second revision of the stickers which are definitely better, but still seem iffy to me.
In particular, Swaps "Re-orient only if required." still seems questionable.
Also, moving the "Flat pieces do not nest" line away from the Tip section could cause an issue.
One suggestion I was considering... If the actions were made more basic and unitary, then the wording could also be reduced as well.
I don't know if word length on the die is a problem, but what if the actions were as follows:
1: <LAY> Turn any solo upright piece flat onto its side in the same space.
2: <STAND> Turn any solo flat piece upright in the same space.
3: <STACK> Stack any solo piece on top of an upright piece.
5: <MOVE> Move a solo piece or stack from any space, to any new space.
6: <WILD> Choose one of the 5 actions. Perform it on either your Tree or The House.
Anyway, after listening to the discussion about what new games could be made to make use of the TreeHouse style sets, I came up with a new single-stash game for 2 or 4 players where each player uses a single trio. Check it out and let me know what you think.
