ABSTRACT:
A sports game with zig-zag ball, intended for fun and recreation. The required playing surface for this game is a flat surface about 1.5 m wide and about 20 m long, on which central line 10 and at least one pin 2 or gate 7 is placed between two fields 9. This pin 2 is crossed around when the ball 3 crosses the central line 10 behind that pin and in front of the next pin 2', and the winner of the game is the player who has the largest number of crossed pins 2 from a certain number of trials. A zig-zag ball useful as a toy or in sports is disclosed. The ball moves in a zig-zag manner when rolled out on a flat horizontal surface. The zig-zag movement is achieved by a mechanism placed inside the ball which alters the center of gravity of the ball as it rolls. In one embodiment of the invention the ball contains an internal shaft with engraved left and right threads, a hollow cylinder slidably mounted on the shaft, a weight attached to the cylinder and a pin on the cylinder contacting and following the threads as the ball rolls and the cylinder turns on the shaft.
