Mini-Viper

Mini-Viper is a 1996 prototype pinball machine created by Sega Pinball, designed by John Borg with concept work by Joe Kaminkow. Rather than a standard commercial release, Mini-Viper was an experiment: an attempt to fit modern pinball electronics and gameplay into a compact, 1950s-sized cabinet, developed in response to operator complaints that contemporary machines were too large for smaller game locations. Sega brought the prototype to an AMOA trade show, but its reduced size was not well received, and it never entered production — only a single unit is known to exist.

Built on the Sega/Stern Whitestar platform and running software adapted from Sega's 1996 game 'Twister,' Mini-Viper is themed around driving a Viper sports car and features two flippers, three pop bumpers, and two shaker motors that activate during multiball. Players work to change a stoplight from green to yellow to red — via ramp shots or upper-playfield targets — to start multiball, and can shift a physical stick-shift toy through six gears, scoring points and jackpots along the way. A miniature Viper car with working headlights sits on the playfield as the game's centerpiece toy, and the game features speech callouts.

Because Mini-Viper never reached production, Sega instead released a full-size version two years later as 'Viper Night Drivin'' (1998). Artist Marc Raneses, who worked on the game shortly before leaving Sega Pinball, recalled contributing only a few of the dot-matrix animations, with colleague Kurt Andersen believed to have done the majority of that work. As a one-off prototype, Mini-Viper is a notable artifact for collectors interested in Sega's design experiments of the 1990s.
