This puzzle has three differently shaped tabs, each kind fitting into between 1 and 3 different kinds of holes. Several challenges are engraved on the back having to do with where the holes are left over (places where the tab doesn’t match the shape of the hole, leaving some extra space). The pieces are an unusual mix of triangles and squares. One of the designers personal favorites, great for all ages!
