Number ball

Abstract

A number ball assembled by an upper and lower ball housings for playing a lotto or bingo game and disposed with an integrated circuit chip inserted therein for a sensor to detect and read is characterized that the spherical surfaces combined by the upper and lower ball housings have six symmetric planes as that on a dice. Various figures or numbers are printed on the surfaces. The surfaces are easier to be printed than that on a conventional spherical number ball; the printed figure is larger and the combination of the spheroid is easier to be positioned and recognized.

1 . A number ball comprising an upper and lower ball housings as well as an integrated chip fixed in the spheroid assembled by the upper and lower ball housings with rim sides thereof glued by adhesive glue is characterized that: 
 the number ball combined by the upper and lower ball housings has six symmetric planes respectively printed with various figures or numbers.    
     
     
         2 . A number ball according to  claim 1 , wherein a circular post is disposed respectively in the upper and lower ball housings with the circular post of the upper ball housing inserted into a post hole on the circular post of the lower ball housing.  
     
     
         3 . A number ball according to  claim 1 , wherein the integrated chip inserts into a post hole on the circular post of the upper ball housing for a sensor to detect and read.
