This disclosure relates to a bouncer device for pin table bumpers and comprises a resilient metallic substantially concave or cup shaped plate having a plurality of equidistant peripheral slots and mounted with its axis substantially vertical on the stem of a pin table bumper, the peripheral edge of the metallic plate having a greater inclination than the other portions thereof. When struck by a ball, the cup shaped plate deforms elastically and causes the ball to bounce away from the bumper.
