The Wikipedia Adventure (TWA) is organized into seven sequential missions (levels), each targeting different learning objectives tied to the five pillars of Wikipedia: (1) Wikipedia is an online encyclopedia; (2) Wikipedia has a neutral point of view; (3) Wikipedia is free content; (4) Wikipedians should interact in a respectful and civil manner; and (5) Wikipedia does not have firm rules. Beyond technical skills, the missions convey Wikipedia's key common norms and rules and reinforce its purpose as a collaborative effort while explaining the project's history and philosophies.
