In order to be able to indicate the position of the ball (12) in which the ball (12) impacts on the skittle erecting surface, for the scoring of a skittle game, a light barrier (20, 30) is provided directly in front of the skittle erecting surface. The signals identified are sent to an electronic processing device (23, 31) which is connected to a display device (33, 34). <IMAGE>
