The variable velocity control for playing images for video games includes a play condition sensor. A horizontal playing image velocity control is connected to the play condition sensor. The play condition sensor receives signals from other portions of the manually controlled electronic video display game indicative of the number of times a ball image has intersected a paddle image. The play condition sensor then supplies a signal, related to a total count of intersections which it has stored, to the horizontal playing image velocity control. The horizontal playing image velocity control, in turn, controls the horizontal speed of the ball image partially in response to the playing parameters of the game and partially in response to a manual switch closing affected by a player.Other References
