Odd Ball Junior

The Odd Ball Junior, manufactured by Daval Manufacturing Co. in December 1938, is a single-player, flipperless electro-mechanical pinball machine typical of the late Golden Age of pinball. It's a 5-ball game featuring 11 spring bumpers -- a center bumper worth 1000 points and ten outer bumpers worth 100 points each, none of which light up.

A distinctive feature is its lighted rollover system: every time the player's score reaches a multiple of 1000 (up to 20,000), the bottom rollover lights up for an extra ball, accompanied by two small non-scoring posts and a lit center backglass indicator. Hitting the lit rollover releases the right-most ball from the outhole trough back to the player. Daval used a similar extra-ball rollover mechanic the following year in 'Side Kick.'

Surviving examples show variation in cabinet artwork -- one specimen, submitted with serial number 3319, was found repainted brown before restoration revealed original artwork resembling Daval's 1939 games 'Box Score' and 'Rajah.' Little else is documented about the machine's designer or original release, but its rollover-based extra-ball mechanic marks it as an inventive example of late-1930s pinball design.
