Time Tunnel, released by Bally in 1971, remains one of the most enigmatic relics in the manufacturer’s storied catalog. Designed by Jim Patla with the distinctive, stylized aesthetic of artist Christian Marche, this four-player electro-mechanical machine draws its inspiration from the cult-classic Irwin Allen television series. With a production run verified at a mere 70 units, it stands as a rare artifact of early 70s design, capturing the campy, high-concept spirit of sci-fi television through the tactile, rhythmic clatter of spinning score reels and traditional mechanical relay logic.
The playfield layout is a masterclass in period-appropriate efficiency, centering on two active pop bumpers and a pair of slingshots that dictate the ball’s frantic trajectory. Navigation is defined by two strategic kick-out holes that demand precise shooting to maintain momentum, while the inclusion of a left kickback lane offers a vital safety net for wayward shots. A double-gated ball return lane complicates the flow, forcing players to account for unpredictable gravity shifts as they navigate the five standup targets. It is a lean, challenging experience that relies on pure flipper skill and timing rather than complex modern software, embodying the challenging, “just one more game” nature of the era’s finest EM machines.
