Q: What size are the new Zendo pieces, relative to regular pyramids? Would they fit in a Volcano board?

A: The pyramids in the new Zendo set are the size of a medium Icehouse pyramid, and the other Zendo pieces have the expected proportions, in other words the square base shape of all of them is the same size. So they will fit in a Volcano board just fine, but they’ll be a little smaller than the squares, since the Volcano board is designed to hold a large.
