- description
- A type of [[gameplay-feature:rollovers]] with a distinctive butterfly-wing shape that flips open when the ball passes over, then springs closed again. The butterfly mechanism provides clear visual feedback — the "wings" fan outward on contact — while the switch beneath registers the score. [[manufacturer:bally]] featured butterfly rollovers on *[[title:grand-tour-happy-tour]]* (1964), using the eye-catching flipping motion as both a scoring mechanism and a playfield decoration. A short-lived design from the [[technology-generation:electromechanical]] era, butterfly rollovers appeared on only a handful of machines before simpler [[gameplay-feature:star-rollovers]] and [[gameplay-feature:rollover-buttons]] became the dominant rollover types.
