Four Diamonds

The Four Diamonds pinball machine, manufactured by J. H. Keeney and Company of Chicago in May 1941, is a representative of the flipperless electro-mechanical games produced in the years just before America's entry into World War II. Keeney, active from 1934 to 1964, was one of the many Chicago coin-op manufacturers competing in this busy period of pinball's development.

Four Diamonds gives the player five balls per game, and its playfield is packed with twenty scoring bumpers. With no flippers to redirect the ball, play centers on the skill of the plunger launch and the satisfying cascade of the ball working its way down through the bumper field, racking up points along the way.

Little is known about the game's design team or intended theme, leaving enthusiasts to appreciate its historical place and gameplay nuances without additional context. Even so, Four Diamonds remains an intriguing piece of prewar pinball history, and its bumper-laden playfield reflects the state of the art in the era immediately before wartime production halted the industry.
