Someone ran a poetry version of An Exquisite Corpse in our group and it worked rather well. Get every participating unit (each Zoom window) to prepare a first line before hand. For each round participants get to see only the previous line of a poem that they haven’t contributed to yet (sent by private chat), they compose the next line and submit it to the organiser by private chat.
Once you’ve done three rounds you will have one four line poem per zoom contributor. Distribute the poems and get people to read them out.
The organiser has to be well prepared, have a scheme set out for collating the poems in a document and for matching participants to poems.
We’ve played pictionary (https://sketchful.io/), charades and a version of pictionary where the clue giver describes the drawing in geometrical terms (sorry, I can’t remember what it is called).
If you’ve played the boardgame Codenames (very good), there’s an online implementation of that game here: https://www.horsepaste.com/
