4 Square

The 4 Square pinball machine, designed by Ed Krynski and released in June 1971 by Gottlieb, is a single-player electro-mechanical game from the company's early-1970s catalog. With 2,200 units produced, it saw a solid production run, and its add-a-ball counterpart was released the same year as Gottlieb's 'Astro' with different artwork.

Gameplay on 4 Square centers on two flippers, three pop bumpers, two slingshots, and eight standup targets, offering plenty of opportunities for players to build their score toward the maximum displayed total of 9,999 points. It is a classic single-ball EM layout that rewards accurate flipper work on the standup targets.

The psychedelic theme of 4 Square is a notable aspect of its design. Gordon Morison's artwork embraces the dancing, music, and happiness motifs of the era's counterculture, giving the game a distinctive period charm that makes it an enjoyable find for collectors of early-1970s Gottlieb machines.
