Abstract: A modular polyhedral object having at least four external faces which each have in the assembled state a different form and/or color design, is formed from several individual building blocks that each forms a part of the form or color design of each external face. The building blocks are joined together loosely or with releasable connecting means, wherein the building blocks of each module have at least four differently designed side faces. A form-congruent assembly of the object is created by arranging the individual building blocks so as to produce matching external faces on each side of the object, as well as to produce matching respective opposing side faces of the building blocks inside the object with vertically and horizontally matching coded pairs. A modular polyhedral cube-shaped object with at least five differently designed side faces is also described.
