Machine Description

Diamond Jack was an electro-mechanical pinball machine released by D. Gottlieb & Co. during the mid-1970s, arriving during a fascinating period when the pinball industry was on the cusp of its transition to solid-state electronics. The machine's theme capitalized on the enduring appeal of diamond heists and treasure hunting, which was popular in entertainment media of the era.

The playfield design featured classic Gottlieb elements of the period, likely including pop bumpers, drop targets, and traditional scoring lanes. As with many EM games of this era, Diamond Jack would have utilized mechanical score reels and relay-based logic for gameplay operation. The artwork and backglass would have featured imagery related to diamonds, jewel thieves, or mining operations, fitting with similar heist-themed games that were popular during this period.

While not one of Gottlieb's most famous titles, Diamond Jack represents an important piece of pinball history from the final years of the electro-mechanical era. These machines were built to last, with robust mechanical components and time-tested reliability that helped many survive to become collectible pieces today. The game exemplifies the engineering excellence of the EM period, when mechanical innovation was at its peak just before the industry's dramatic shift to electronic systems.
