The MSO consists mainly of single event competitions most of which are for the nominal title of Olympiad champion, though some trademarked games are authorised by the game designer and publishers as the official world championships. All games, whether an Olympiad or the official World championship, can count towards the Pentamind. Medals, and more recently trophies, are awarded for gold, silver and bronze positions in each competition as well as ranks, with similar awards for the top juniors in each event. In early Olympiads sponsorship allowed for generous financial prizes to go with many of the events. In recent years such prizes have been limited to a small number of events, usually as a result of specific outside sponsorship for that discipline.
