Two players create a new invention. Player one starts with an object (“We’re making a shoe”). Player two builds on that (“Yes, and this shoe is really soft”). Player one continues building (“Yes, and because it’s really soft, it’s really great to cuddle with”). The players keep alternating, every time building on the last thing that was added to the invention, in the format “Yes, and because [last addition][new addition]” (“Yes, and because it’s great to cuddle with, it’s really easy to make new friends with it”)
