Scrawl

Revealing the terrible artist in all of us, players in Scrawl start off with a loaded phrase, doodle it, then pass it on. By the time your masterpiece of an "OAP Conga Line" passes through your friends’ weird minds and wonky pens — and makes it back to you — things will have gone horribly wrong. Points are awarded for the most disastrous doodles and godawful guesses. Most grins wins.
