From the box:
In Articulation the player with the best vocabulary will not always win! The game has been designed to provide a level playing field. Duel squares, stop squares, and free roll squares are but some of the equalizing factors in 'Articulation'. Coming from behind to win is the rule and not the exception.
The five categories are slang, jargon, word origins, spelling and vocabulary. The cards, except spelling, are multiple choice.
