These pics show the versatility of the Spiel mit!® Bau-System Universal.  By design, smaller blocks easily substitute larger blocks.  11 Spiel mit!® Original pouches were used to build this tower (218 x 1/1 (full length), 79 x 3/4 length, 80 x 1/2 length and 77 x 1/4 length blocks) - easily achieved if several friends bring their Spiel mit!® for an afternoon of fun.
