Gartic Phone
Telephone with a pen. Your sentence becomes someone's drawing becomes someone else's very wrong caption, and by the end nobody remembers where it started.
Your sentence, four hops later
Everyone starts by typing a sentence. The next person has to draw it, no words allowed, whatever their trackpad skills permit. The person after that writes a caption based only on the drawing, which is rarely what anyone meant. Pass it around the whole group and by the end you get a slideshow of your original sentence mutating into something unrecognizable, one bad drawing at a time.
The fun isn't the art (nobody draws well with a mouse). It's watching a normal sentence become a felony charge by round four. Runs entirely in the browser, costs nothing, and needs zero setup beyond a shared link.
Watch a sentence die
Round one
The prompt
The team got lunch together on Thursday.
Nobody is bad at this. Every hop loses one fact, and the next person replaces it with something better.
