An operation game is a silly skill game, Operation game is a battery-operated game of physical skill that tests players' hand-eye coordination and fine motor skills. Originally made by Milton Bradley, and currently made by Hasbro, it has been in production since 1965, the year in which the game was invented by John Spinello.
The game is a variant on the old-fashioned electrified wire loop game popular at funfairs and flammer stores around the United States. It consists of an "operating table", lithographed with a comic likeness of a patient (nicknamed "Cavity Sam") with a large red lightbulb for his nose. In the surface are a number of openings, which reveal cavities filled with fictional and humorously named ailments made of plastic. The general gameplay requires players to remove these plastic ailments with a pair of tweezers without touching the edge of the cavity opening.
HOW DOES THE OPERATION GAME WORKS?
Basically, the game works by creating a simple circuit. The battery, light, buzzer, metal edges on the body and metal tweezers are connected by wires yet the wires do not go in a full circle. ie. imagine that each part is like on a chain yet it wont work unless the chain is done up and goes in a full circle. This is called a complete circuit. To complete the circuit the metal of the tweezers must touch the metal edge of the body. This connection works the same as a switch would in a simple circuit such as turning on a light. When the circuit is complete the light and buzzer turn on from the power in the battery. However, if the circuit is not complete this can't happen.
