The game title Whoforwat summarizes the gameplay: Each round, players collectively vote on who is doing...something.

At the start of each round in this co-operative game, lay out six zigoto cards, with each zigoto being a unique, dadaistic living being from the mind of designer/artist Edouard Didelot. Reveal an illustrated question card, such as "Who loves dogs?", "Who ran through this wall?", or "Who would be a good couch?"

Players secretly vote on which zigoto seems like the best who for this what, then they reveal their choices. If no zigoto has received more votes than any other, discard all the zigoto cards and play another round; if a zigoto has received more votes than any other, place it aside for the grande finale, then play another round; and if a zigoto received everyone's vote, place it aside for the grande finale along with a special "connexion" token, then play another round.

Once you've set aside six zigotos, lay out those cards, then play the final round. Reveal a question card, then everyone votes and reveals as normal. If you've all voted for the same zigoto, you win! If not, discard a connexion token and vote again on this same question. If you run out of connexion tokens before unanimously choosing a zigoto, you lose.
