Zendo is a game of inductive reasoning where players try to figure out what Rule causes certain pyramid arrangements to be marked black or white.
This is a packet of cards with easier Rules for novice Masters who don't want to (or shouldn't!) make up their own Rules yet, to play with beginning Players who are still developing their skills.
Five Treehouse tubes (all Rainbow or all Xeno) are regarded as the minimum to play. Full rules for the game can be found in the book Playing With Pyramids, or online.
