Word at a Time Story: Two or more improvisers alternate words as they tell a story. If done well, this game can be very entertaining. It teaches the skill of being 'in the moment' (not planning ahead), since there is no way to anticipate the direction in which another actor will take the story.
Yes, Let's: Each improviser in a scene makes a suggestion that is loudly accepted by the others on stage with the words "Yes, Let's". When used as an exercise, this game teaches acceptance of suggestions by other improvisers and the value of a positive attitude on stage.
Guess My Word: An improviser leaves the theatre to allow the audience to suggest a secret word. The improviser then returns to the theatre and tries to guess the word as suggested by another improviser in a scene. This game teaches improvisers to be alert to the actions of others in the same scene.
Status Switch: Improvisers create a scene with an obvious high-low status relationship. Before the end of the scene, that relationship must be reversed (e.g. the meek customer turns the tables on the owner of the bank). This type of scene teaches the improvisers to be aware of the status levels of the characters in the scene, just as we do unconsciously in real life.
Genre Replay: The audience chooses a number of different styles and the same scene is repeated and altered to reflect each style in turn.
Puppets: This game involves players that aren't allowed to move independently (apart from speaking) and other players (sometime audience members) have to physically move them. Variation Torture Puppets: one 'puppeteer' must manipulate two or more "puppets'.
