Sakes Alive -- It's World War 5 Using a 3HOUSE set (the pyramids from three Treehouse sets) as army units each player starts with total control of one of the six continents (each of which is broken up into three zones and has nine international travel routes). The goal is simple: conquer another continent while retaining a toehold in your own. A copy of this gameboard plus six regular d6 dice and three Treehouse sets are required to play.
