Each player is given a word, number or famous phrase (preferably not something said in every sentence.) Whenever the player’s word is spoken within the scene the player must justify an entrance or an exit.
To improvise and justify within the rules of the game while creating a scene.
Players should be asked not to say their own word unless necessary to avoid the trap of “saying it for laughs.” Be sure to remember to create an activity and find a common focus for the players within the scene. You can also try to forward the story with each entrance and exit.
