This is the family sized (4-6) player version of Telestrations. Gameplay alternates between drawing an image based on your given word, or guessing a word based on the image you've been given. The humor starts to come out when people misinterpret what they had, and the results become more and more outrageous.
Its like the old game of telephone with illustrations, hence the name.
