1. An inflatable ball for ball games comprising:
- a circumference with a selected measurement (C);
a surface having a number of interconnected basic panels comprising eighteen squares, twenty four trapezoids and eight equilateral triangles, said squares having four sides of substantially equal length (a) and two corresponding diagonals of length (d), said triangles having three sides of a substantially equal length (c) and a central point (Y) and said trapezoids having four sides composed of two legs of said length (a), one base of said length (a) and a smaller side of said length (c);
said trapezoids being enclosed by three of said squares and one of said triangles, wherein said sides (c) of said trapezoids are connected to said sides (c) of said equilateral triangles and said sides (a) of said trapezoids are connected to said sides (a) of said squares; and
the relation of said circumference measurement (C) with said length (c) ranging between a first ratio of (c)=6.436% (C) and a second ratio of (c)=6.25% (C) and said length (d) of said diagonals of said squares being substantially equal to one eighth of said measurement (C).

Abstract
A ball for ball games, organized in 18 squares and adjusted by 8 helices, wherein the ideal sphericity is obtained when the distance from the center (Y) to the corners of the triangle in the center of the helix is equal to the difference in distance that exists between the square and its diagonal: If c=sqrt(3)*(d−a) and d=⅛C, then sphere.
