Hi Jack!

"Hi Jack!" is not a released Bally pinball machine but surviving concept artwork by artist Dave Christensen for a Cops and Robbers themed game that was never produced. It isn't known whether the design was ever seriously considered for production by Bally Manufacturing Corporation, or simply an unused art concept.

The artwork carries design cues typical of late-1960s Bally output: four-digit score displays and an extra "Bonus Loot" scoring feature for each of its intended four players, both features Bally used in games from that period. This suggests the concept dates from around that era, even though it was never turned into a working electro-mechanical machine.

As unrealized pinball art rather than a manufactured game, "Hi Jack!" offers a glimpse into ideas that circulated within Bally's design process without ever reaching production — a reminder that not every piece of period-appropriate pinball artwork became a cabinet on the show floor.
