Son of Fireball

Son of Fireball was never actually manufactured - it exists only as backglass artwork by Dave Christensen, apparently intended for a solid-state Bally machine, though the Bally name does not appear on the art and it's unknown whether the game was ever formally considered for production. The name suggests it may have been conceived as a follow-up to Bally's earlier 'Fireball,' though this connection is not confirmed by the available records.

Because no machine was built, no gameplay, rules, or theme details survive to describe beyond the artwork itself. Based on the four-score-display and credit/match window layout typical of Bally backglasses, the art is estimated to date from sometime between 1976 and 1986.

As an unproduced concept, Son of Fireball is of interest chiefly to collectors and historians of pinball backglass art and unused Bally designs, rather than as a working machine.
