Lucky Dice

Lucky Dice, built by Ramtek Corp. of Sunnyvale, California and tested in May 1975, is one of the earliest known solid-state pinball games, built from scratch around an Intel 4004 microprocessor chip. This makes it a landmark piece in pinball history, representing an early step toward electronic technology in the industry, well ahead of the wider industry shift to solid-state games later in the decade.

Only three units were built, each in a different color, and the game was shown privately in a hotel room at the 1975 Music Operators of America exposition (MOA) in Chicago. Despite this exposure, Lucky Dice never went into production, making surviving information about it scarce.

Gameplay centered on its "Playing Dice" theme, though specific rules and features are not well documented. Its status as one of the first microprocessor-based pinball prototypes makes Lucky Dice a significant curiosity for collectors and historians of early electronic gaming, even though it never reached the commercial market.
