Rainbow Belle

Rainbow Belle was manufactured by Bally Manufacturing Corporation as model 746. It is not a pinball machine but a payout "electronic upright," also called a flasher-type slot machine. Unlike most games of this type, which award only credits, Rainbow Belle gave operators the choice of awarding either cash payouts or credits — a notable option that distinguishes it from similar uprights. Upright payout games like this were typically built for export.

Rainbow Belle is a single-player game with a cabinet advertised at 57 inches high, 20 inches wide, and 20 inches deep. Its schematic is identified by part number W-885-15d.

Beyond these details, little further documentation survives about the machine's specific artwork, designer, or exact release date, leaving some aspects of its history uncertain.
