4x4

The 4x4, manufactured by Maquinas Recreativas Sociedad Anonima (Maresa) of Madrid, Spain, is an electro-mechanical pinball machine that is a copy of Gottlieb's 1971 '4 Square.' Its exact release year is not documented, but its music, people, and op-art theme reflects design trends of its early-1970s source game.

Gameplay features two flippers, three pop bumpers, two slingshots, and eight standup targets. The wedge-head design and drop-down cabinet are typical of Maresa's EM output, and the maximum displayed score of 9,999 points is reached with EM chimes rather than electronic scoring sounds.

Maresa was one of several Spanish manufacturers producing EM copies of American designs during this era, and the 4x4 stands as an example of that practice — closely following Gottlieb's original '4 Square' layout while carrying its own regional branding and artwork.
