Abstract: A multi-phase analytical game activity, is prefaced with a construction phase, in which are constructed from component elements, a plurality of [co-operatively-disposed] playing pieces (11), such as hollow, co-operatively inter-nesting cubes; with coded marking of individual facets (15), according to designated topics and subsidiary categories; whereby cube and facet juxtaposition reflect topic inter-relationships and hierarchies; in a follow-on board game phase, progress around a designated playing area is determined by random chance selector means, and coding of placement areas triggers selection of topic query cards for topic exploration.
