Knock Out

The Allied Leisure Industries' Knock Out, released in 1974, is an early solid-state electronic (SS) coin-operated game - a target/gun-style title rather than a traditional flipper pinball. Cash Box records show a California distributor referencing a delayed shipment of the game in August 1974 due to an airline strike, giving an approximate release window for the title.

The objective is to "knock out" the opposing player in head-to-head competitive play, using the machine's solid-state scoring and sound system - a step up in precision and presentation compared to earlier electromechanical designs. The manufacturer's flyer touted "no moving parts to wear out," though exactly how the game's shooting-gallery targets were displayed is unconfirmed.

Knock Out's design and artwork carry no documented theme, and little else is known about the machine's designer or reception. Still, as an early two-player solid-state title from Allied Leisure, it offers a window into the industry's mid-1970s shift toward electronic gaming.
