There is two ways to play this game neither is wrong
You either
A. Make a story for each individual gif
B. Make a story for all gifs combined
How does this work?
Well.... When I first made this up. With my friends we would wait until we all had posted 4 gifs each
but seeing as this is a forum. You'll have to interpret everyones, there will be no waiting
Say person A posts 4 gifs and 3 people reply with stories, then 6 days later person B posts 4 gifs.
It doesn't mean people can't reply to person A's gifs and likewise for person B.
You can always reply and make up a story.
