Clearance of the company by displacement of the balls on a plate or the like.

摘要

The game is played with a spherical ball (1) which is moved between two compartments (11, 12) on a board. The first compartment (11) has an opening (21) whose width diminishes from a maximum value (31) to a minimum value (32). Its narrower end (33) is turned towards the second compartment (12), which has an identical opening to that of the first. The semi-circular opening edge (37) of the first compartment stops the ball. Its diameter is less than the diameter of the ball, but the length (38) of the opening is greater than the radius of the ball.
