Rainbow

The Rainbow pinball machine, produced by J. H. Keeney and Company Incorporated in 1936, is an early example of electro-mechanical pinball technology, predating flippers by more than a decade. It was offered as a payout machine and was also available in a Free Play model or a Ticket model at extra cost.

Little detailed information survives about Rainbow's specific gameplay features, scoring, or playfield layout. As an electro-mechanical machine from the mid-1930s, it would have used relays and switches for scoring rather than the flipper-driven, player-controlled mechanics that arrived later in the decade.

Beyond its manufacturer, release date, and payout format, no detailed information on its design, art, or theme is available, leaving enthusiasts to speculate about what made this machine tick back in 1936.
