A new Zendo 3.0 cards deck is currently only available as a print-on-demand product which you can order through the Game Crafter.
(The version of these cards that we created as a stretch goal for the Pyramid Quartet Kickstarter campaign is sold out, but in 2026 we did major development work to create a new version of these cards! Although superficially similar to the deck we made in 2020, the cards in this version are packed with more options each, so that with just 52 cards (vs the old deck’s 60) it generates ~1700 unique rules (vs. ~200). The new cards also have 4 difficulty ratings (instead of 3) and were playtested extensively in a process described here and here.)
