Mark a story that interests you. You are seated with people in other countries who marked the same one, and each of you writes your own account before any of you reads a word of anyone else’s.
Pick a party of two or a party of four. Different countries first. Nobody reads until everybody has written.
A board of stories is open. If one interests you, mark it. Nobody sees who else has.
You are seated at the party you picked, a party of two or a party of four, with people in different countries wherever that can be managed. You can be seated with somebody from your own country only after a day or more has passed without anybody from another country turning up, and not at all if you have switched that off. Each of you writes your own account before any of you can read a word of anyone else’s. This takes a day or two, because writing does.
When the last person files, all of it arrives at once. Three sentences is a complete answer. Nobody was influenced, because nobody had seen anything.
Each person at the table answers one other, so nobody writes into a room. That is where it ends.
