You each take a piece of paper and a pen. You shake the die and put them in the box, so you get a nice 3 by 3 grid (or you just arrange them in a 3 by 3 grid). You need a kitchen timer for this one as well.
You set the timer for 25 minutes (one pomodoro) and you write a story based on as little as one die or all 9 die in the 25 minute span of the game. Each round is 25 minutes, if you are willing to play more than one round.
After this round, you each take turns telling your stories.
No points, no competition. Just innocent, creative fun.
Could be a fun game to play at a write-in during Nanowrimo.
