Ten Pin

The Ten Pin is a 1-player novelty pinball machine from Bally. Bally's Numerical List of Machines shows Model 871 released to production on November 21, 1969. Little else is documented about this game: there is no wiring part number on record, and it does not appear on the game lists found in Bally's parts catalogs, leaving it unclear whether Ten Pin was ever actually produced in quantity.

Because so little survives about the specifics of the machine, details of its playfield layout, features, and artwork remain unknown. What is clear is that it falls very late in Bally's long electro-mechanical history — the company had already been manufacturing pinball machines for nearly four decades by 1969 — rather than representing an early or pioneering release.

Ten Pin stands as one of several ambiguous entries in Bally's catalog: officially logged as heading to production, yet without confirmation that any units ever left the factory. Until further documentation surfaces, its exact fate remains a mystery for pinball historians and collectors.
