A friend was disappointed on playing books II-IV that, unlike in book 1, pumpkins are completely inert. With some help and playtesting, I developed the Books of Pumpkins.
They're quite fun. You probably want to mix these in sparingly, by choosing randomly. A completely pumpkinated game is quite odd.
We have some house rules which improve turn-taking, adjust the balance of certain chips, and clarify some points.
FTR, we no longer play on the test tube side of the boards. In our experience this significantly overpowers blacks. We have not yet found a good way to debuff them by about the right amount.
The Books of Pumpkins, etc. are extensions to Quacks of Quedlinburg, and are Free Culture. See the git repository for source code.
