Number Roll

Number Roll is an electro-mechanical rolldown pinball machine from Genco Manufacturing Company, built for two players. As with many rolldown games of the pre-flipper era, gameplay likely centered on launching a ball to score points based on where it landed on the playfield, without any player-controlled flippers to redirect it mid-play.

Genco was one of the prolific manufacturers of the early pinball and rolldown-game era, and Number Roll reflects the simple, durable electromechanical construction typical of the format. Beyond its basic classification — a two-player EM rolldown game — detailed records of its release date, specific scoring mechanism, and original artwork have not survived.

As with many surviving Genco rolldown titles from this period, Number Roll is a fragment of pinball's early history: more information about its exact year of manufacture and gameplay rules would help place it more precisely within the era's development.
