Simon

Simon is a Bally whitewood prototype that was never produced. Conceived by Norm Clark and designed by George Christian, it was a four-player, solid-state game built around the electronic memory game Simon, likely developed shortly after Bally's Mr. & Mrs. Pac-Man Pinball.

According to designer Greg Kmiec, the playfield featured four colored inserts (red, yellow, blue, green) matching the Simon handheld toy, along with a smaller matching light box mounted on the lockdown bar. Advancing the bonus and capturing the ball in a saucer would start a video mode in which the playfield displayed a Simon-style sequence for the player to repeat using buttons on the lockdown bar, with the sequence growing progressively harder.

The concept was ultimately judged flawed -- too slow to build tension, with too much downtime and thinking required for a game meant to be played in a bar -- and the whitewood was scrapped before Bally's move to Bally/Midway. No production units exist, and Bally's own documentation makes no mention of the game, leaving Kmiec's recollections as the primary record of this unusual unreleased concept.
