Flip Flags

A domino-sized hinged device mounted on the playfield that flips to show one face or the other, indicating whether a particular feature or award has been earned. When the game state changes, the flag physically rotates to display a new color or symbol — a mechanical status indicator visible at a glance during fast-paced play. Flip flags are exceptionally rare: only three Bally machines are known to have used them, making them one of the scarcest playfield mechanisms in pinball history.
