Professional Pinball: Challenger IV

The Professional Pinball Challenger IV is one of five conversion kits manufactured by Professional Pinball of Toronto in 1981. This solid-state electronic (SS) game is a conversion of Bally's 1978 'Strikes and Spares.' The conversion kit included a new backglass, playfield overlay, and playfield light shields, giving the machine a new identity distinct from its bowling-themed source game.

No specific theme is documented for the Challenger IV itself, which suggests a more generic or minimal presentation compared to the original licensed Bally title it was built from.

While little is known about this machine's design, art, or production history beyond its conversion origins, it remains a notable example of the early-1980s conversion-kit business, where companies repackaged existing pinball hardware with new branding for continued commercial life. For collectors and enthusiasts, the Professional Pinball Challenger IV offers a glimpse into this niche corner of pinball history.
