Delto was the winner of the 2009 Concours International de Créateurs de Jeux de Société (The Concours International) Delto is a game that allies aesthetic, elegance and the pleasure of thinking. As it is mentioned in the title of the game, the players manipulate triangles trying to make the most extended row with their colour. Each turn the choices are simple : put a piece in the axis from the common reserve or move one already in play. The efficiency of this game comes from the fact that the material channels the rules : if a triangle can’t pass over another one then the move is forbidden. The accessibility of the rules allows everyone to plunge into a surprising game in which the material allies aesthetic and handling pleasure.
