Knockout

The Bally Manufacturing Corporation's 1975 electro-mechanical machine Knockout is a two-player boxing-themed pinball game designed by Greg Kmiec with artwork by Dick White. Its EM design reflects the era just before solid-state electronics took over the industry.

Knockout's gameplay centers on its boxing theme, with two flippers, two pop bumpers, two slingshots, and a kick-out hole. The two spinning targets require precision and timing to hit, while its twelve star rollovers let players light chicane lane awards and build an end-of-ball bonus, adding a layer of strategy to each game.

A confirmed production run of 2,085 units puts Knockout among the more common Bally boxing-themed titles of the mid-1970s, reflecting the bold colors and boxing-ring visuals typical of the period's cabinet and playfield art.
