Operation Buzzer, Doctor Card & Solo Rules Explained
This page covers the U.S. Hasbro B2176 edition.
What triggers the buzzer?
If the metal tweezers touch the metal side of an ailment opening, the circuit closes, the buzzer sounds and Cavity Sam’s nose lights.
Does a buzz end the attempt?
Yes. A buzz means the ailment was not removed successfully on that attempt.
Doctor cards
Doctor cards identify an ailment and a money value. Remove the named piece cleanly to earn the reward.
What counts as a clean removal?
The ailment must leave its opening without the tweezers touching the metal side.
Solo play
Hasbro lists B2176 for one or more players. In solo play, use the same dexterity challenge and work through the ailments; there is no need for a multiplayer money comparison.
