At least one kind of building block is polygonprism blocks which have grooves to fit for the protrusive arris or have grooves to fit for protrusive arris on the main shell body.
The striking body is made of metals, stone materials or other hard materials, and the striking body is in the shape of a round ball, a football, a polygon ball, a column or a polygonprism.
