User A describes up to three images that User B must find on Google Images. User B brings these images back, then describes up to three more images for User C to find. Play continues like that. Example:
User A: Bring me pictures of a mythical creature, a Mexican dish, and a common household appliance.
User B: (insert picture of a gryphon, a taco, and a plunger) Bring me pictures of a citrus fruit and your favorite brand of soda.
User C: (insert picture of an orange and a can of Coca-Cola)
