These sturdy and elegant boards are made for us by a local game/puzzle company. They are formed by a black laser-cut grid affixed to a white base. MegaVolcano requires the equivalent of 10 different monochrome stashes. Rules are in the book Playing With Pyramids, or online.
The MegaVolcano board is the largest of its kind we carry, and therefore the most versatile: just pick up some ELBS (see below in Related Items) and you can convert down to a 5x5 (or smaller!) board whenever you want.
If you are looking for a larger board, you can now order Volcano boards in 7x7, 8x8, and 9x9 configurations directly from our supplier, Kadon.
There are many other games for the pyramids that which use this board. Check online for more info.
