In Peptide, players make a set of thoughtful selections from a number of openly available Organelle Cards (that are then removed) creating an interactive open-card-drafting mechanic. Players do this in order to link Amino Acid cards side-by-side, thus building a protein chain, and thus scoring points!

Peptide is an open-card-drafting similar to a worker placement, except players take the openly available cards rather than placing workers or meeples, creating a very intense experience with few rules.
