Which classic board game, first released in the 1960s, has players remove pieces like a "funny bone" without setting off a buzzer?

Operation is the answer. First released in the 1960s, Operation is a classic board game built around Cavity Sam, electric-contact gameplay, and a buzzer that sounds when players using tweezers touch the edge of the opening instead of cleanly removing a piece.

The Electric Buzzer Challenge

Operation is a dexterity game in which players use tweezers to lift small plastic pieces from openings in the patient’s body. Each opening is edged with metal, so if the tweezers touch the side, the circuit closes and the buzzer goes off. That simple electric mechanism turned hand-eye coordination into the game’s main challenge and gave the board game its most recognizable feature.

Cavity Sam and the Game’s Odd Pieces

The patient on the board is known as Cavity Sam. The removable pieces have joke names such as the “funny bone,” which gave the game a cartoon medical theme instead of a realistic one. That mix of careful movement, tweezers, and silly body-part pieces helped make Operation easy to recognize in toy stores and family game collections.

From Original Concept to Store Shelves

John Spinello is credited with creating the original game concept, and Milton Bradley published the commercial version. Operation became one of the best-known dexterity games of its era because it combined a simple skill test with an electronic gimmick that felt fresh in the 1960s. Its identity stayed tied to the buzzer, Cavity Sam, and the challenge of removing the pieces without setting anything off.
